How much snow have you got?

[Roger J Smith]

The main part of this storm is now over North Dakota and Minnesota, with amounts of 10-20 cms being reported. A hangback low over Idaho-southeast B.C. continues to promote light snow further west, have heard some reports of 25-30 cms in Alberta.

A stronger storm is about to develop in Nevada-Utah on Monday and will move across Colorado into Nebraska on Tuesday, bringing the threat of 30-50 cms of snow for parts of South Dakota, North Dakota and Minnesota on 28th-29th. This one may have a significant freezing rain swath ahead of the warm front hitting southern Minnesota and central Wisconsin.

Both of these storms are due to weaken once into the Great Lakes region and will become rather minor snowfall producers further east (5-10 cms) while maintaining the mild trend along the east coast.

How much snow have you got?

Judging by the fact it has taken me 2 hours to clear my drive..i would say in excess of 30cm has fallen

Nice bit of snow!

We got a cold week in store for us anyway all week till Sunday, Northerly wind daytime highs of around minus 5 to minus 10, add another minus 10 top with the windchill, certainly one of the coldest snaps of the winter. Not really any snow in the forecast though besides flurries, really am wondering when or if the next big snow storm will happen, last one was Feb 2nd here!

Snowmaggedon: Winter storm barrels toward Brainerd lakes area

More than a foot of snow possible

Snomaggedon is coming.

“This is going to happen,†said Amanda Graning, National Weather Service meteorologist in Duluth. “This is a big one. We are going to make up our winter here.â€

Winter storms have slipped past the Brainerd lakes area. In fact, that’s been the routine this season. But this time, the weather service computer models are in agreement. A powerful winter storm carrying heavy, wet snow and packing gusty winds is bearing down on the Brainerd lakes area like four burly guys packed into a bobsled. The weather service described it as the strongest storm of the season by far. “The latest trend is for the band of heaviest snow to be in the Brainerd to Duluth area,†Graning said. “The greatest potential to see over a foot does include the Brainerd area.†That means the narrow band may dump a good foot-and-a-half of snow in the lakes area. Graning said the heaviest snow may not be larger than a countywide event, which is why the weather service is issuing a winter storm warning with a range. “There is going to be a pretty broad swath of more than 8 inches.â€

For those who have travel plans, plane tickets or events that can’t be missed, the message is to leave early. “(Tuesday) night is going to be a brutal night,†Graning said. “The main show should get going during the evening hours. Right now the warning does begin at 6 p.m. so anyone with travel plans after 6 p.m. will want to watch how things evolve.†The winter storm warning is in effect from 6 p.m. Tuesday to 6 p.m. Wednesday. The weather service predicts the heaviest snow will be south of Highway 2 and the strongest winds at the head of Lake Superior. Snow fall totals greater than 14 inches is possible in from Pine River to Hayward, Wis. Winds are expected to be strong and relentless, causing a blizzard warning to be issued for West Central Minnesota.

Sleet or ice may fall farther south, such as the Twin Cities region and southern Minnesota. Folks in International Falls may only read about snow in this storm without ever seeing a flake outside their windows. The weather service issued a winter storm warning. It is expected to start slow with about an inch of snow falling Tuesday, Feb. 28, mainly after noon. By nightfall, heavy and blowing snow is anticipated. Winds may gust to 30 mph. The weather service isn’t hedging bets. It lists the chance of precipitation at 100 percent. Snowfall amounts may reach 9 to 13 inches. And it may not be done yet with more snow, and blowing snow, expected well into Wednesday.

On the plus side, temperatures are expected to remain mild and near 30 degrees. But the wind, expected to move snow with force, may put a bite into the warmer air. After months of being in a quiet and dry weather pattern with storms slinking by instead of dropping in, there is a change in the air. “Our weather pattern has kind of shifted so we have more of a storm track over our region,†Graning said. “Storms were going north and west and southwest storms out of the Rockies typically bring the snow. It’s definitely a pretty active pattern. Now we do see a few more little systems coming through.†Another system is coming up Friday. The current track is taking the storm over Michigan but is expected to bring heavy snow to Wisconsin. But the weather service is watching the path. It wouldn’t have to shift much to bring that heavy snow to central Minnesota, Graning said.

But first things first. The approaching storm creating this winter storm warning is moving out of Nebraska and expected to track right over Minnesota and extend to Green Bay, Wis. With that track, Brainerd will be on the north side of the low pressure system. That side of the snow is the cold side and more favorable for heavier snow. “We have very high confidence in this storm,†Graning said. “It’s going to be nasty.†The heavy snowfall may be coming down at such an intense rate to create “thunder snow†as the winter storm takes on thunderstorm intensity with lightning and booms of thunder.

“This kind of really heavy snowfall, when it is coming down at intense rates that we are expecting Tuesday night, plows can’t keep up with that snowfall and we are expecting that through much of Wednesday,†Graning said. She advised people to think ahead and prepare for possible power outages, as well as be safe themselves and check on neighbors. Once the snow stops, people will want to take their time shoveling or depend on those with snowblowers and plows. On the plus side, Graning said the snow is coming so late in the season, people can see the end already. Dealing with this snow now means a winter of just weeks remaining instead of months.

FRESNO, Calif. (AP) — Heavy snow and strong winds have rushed into California's Sierra Nevada, finally giving the area a long-overdue blast of winter.

A winter storm carrying the prospect of up to 5 feet of snow for the Northern Sierra began to hit late Tuesday and was expected to last well through Wednesday, putting state road crews on alert while brightening the state's water outlook heading into spring. "After tonight, you probably don't want to travel in the Sierra until Thursday," said George Cline, a forecaster with the National Weather Service. State surveyors from the Department of Water Resources measured the Sierra's paltry snowpack on Tuesday and found it just 30 percent of normal.

The Northern California storm could ease fears among the 29 agencies that depend on snowmelt delivered through the State Water Project that already are bracing for meager allocations. Some farmers on the west side of the San Joaquin Valley have been told to expect just half of the water they requested for the spring and summer growing seasons. The forecast calls for snow in both the Sierra and Coast mountain ranges with the biggest wallop coming above 6,500 feet, where accumulation could be between two and four feet, and up to five feet at the highest elevations. The cold front sweeping down from the Gulf of Alaska will also bring gusts up to 110 mph along the Sierra crests, and 60 to 70 mph "where people are," Cline said. Snow levels could drop to 2,000 feet. "It's going to be pretty miserable through tomorrow," he said.

Caltrans is bracing for what could be the biggest snowfall of the extremely dry winter by having Sierra crews work continuously on 12-hour shifts. On Interstate-80, the main east-west trucking corridor in Northern California, at least 200 people operating 134 pieces of equipment will be on duty. On Interstate 50, 100 people and 74 pieces of equipment will be working to keep roads clear. Supervisors on the road will monitor ice conditions and decide with the California Highway Patrol when to require chains. In the Coast ranges, forecasters predict six to 12 inches of snow above 3,000 feet and four inches at 2,000 feet. Up to a half-inch of rain is expected in the Sacramento Valley with scattered showers farther south. Along the coast, up to an inch of rain could fall on areas north of the San Francisco Bay, with showers diminishing near Monterey

PORTSMOUTH (Maine US) — The calendar says winter isn't over yet, and meteorologists say Mother Nature is about to prove it.

Forecasters are predicting the Seacoast is going to get slammed tonight with a snow storm that might remind locals what winter in New England is all about. Jon Cannon, meteorologist with the National Weather Service in Gray, Maine, said projections are calling for 6 inches of snow on the Seacoast and up to 10 inches inland. If the forecast is accurate, it will represent one of this winter's largest snow events. According to Crescent Snow and Ice Management, Portsmouth has seen only about 12 inches of snow this season through mid-February. That compares with 73 inches in 2010-11.

Cannon said he expects snow to start falling at about 5 or 6 p.m. today, continuing through to Thursday evening. On the Seacoast, the storm may turn to rain or freezing rain Thursday, but the western half of Rockingham County and all of Strafford County should see snow all the way through the storm, he said. Utilities and road crews are watching the forecasts closely and are taking steps to prepare. Unitil spokesman Alec O'Meara said a third-party weather service gives the company updates twice daily and that Unitil has been in a "heightened sense of readiness" since Monday.

Mike Skelton, communications specialist with Public Service of New Hampshire, said crews are ready to respond to any potential power outages. The good news, he said, is that the forecast in most areas is calling for a dry snow that is less of a hazard for power lines. "As of right now, it appears the snowfall will be relatively manageable," he said. Bill Boynton, public information officer with the N.H. Department of Transportation, said road crews will begin checking equipment during the day today in preparation for the evening snow. He said plow operators are expecting to work all night and have adjusted their schedules accordingly.

Due to a relative lack of snow this winter, Boynton said the state's salt and sand reserves are in good shape, but he has been warning people not to get too excited until winter is truly over.

"There's still winter to come and here's an example," he said.

Boynton reminded drivers "spoiled" by snow-free roads that they likely will not be able to safely drive 65 mph on the interstate in a storm. He said the DOT may issue speed advisories as needed. Cannon said milder temperatures are coming and that the forecast calls for rain in the middle of next week

In the midst of probably the coldest snap all winter here, as we head into March and the 1st day of meterolgical Spring tomorrow may well be the coldest overnight and daytime highs we've seen from the previous 3 months. Is a gloriously sunny high pressure though, if you can walk with the Northerly wind behind you and the sun facing you it almost feels warm can really feel the sun now, till youturn around and walk into the wind is like a different world!

Expected to warm up over the weekend back more average March temperatures with a system on Sunday bringing snow rain. Have seen a couple of sites forecasting us some more significant snow for around next Tuesday though I know is a long way off, anyone think the conditions here more favourable for snow next week?

Blizzard warning issued for Twin Ports

The winter storm took longer than expected to move into the Twin Ports, but it’s packing a wicked wallop this morning with heavy snow and winds gusting to more than 60 mph at the head of Lake Superior.

The National Weather Service in Duluth has issued a blizzard warning for the Twin Ports, with snow falling at more than an inch an hour causing near-whiteout conditions.

The storm slowed down while moving north and hit Northwestern Wisconsin the hardest overnight, with up to 17 inches in parts of Burnett, Washburn, Price and Sawyer counties and more still to come. Pine County in Minnesota also has received a foot of snow.

U.S. highway 2 and 53 are closed in some areas, officials said, and the city of Duluth is asking residents not to travel if they don’t have to. Some trees are reported down on roads and some transformers have been reported blown.

“Even if you manage to get in to work today, you might not be able to make it back home,†said Kelly Fleissner, manager of maintenance operations for the city.

In Duluth, more than 6 inches had fallen at the airport by 10 a.m. and heavy snow is expected all morning, said Kevin Krujalis, assistant forecaster at the National Weather Service in Duluth.

“We’re still thinking 8 or 9 inches storm total by this evening if it keeps up this heavy stuff all morning,’’ he said.

But the storm never made it much north of Duluth, and areas from the Iron Range north now are expected to see little accumulating snow.

Wind gusts at about 9 a.m. this morning hit 60 mph on the Blatnik Bridge, 55 mph at Sky Harbor Airport at the harbor and 47 mph at Duluth International Airport. Visibility in the Duluth area was about an eighth of a mile, and roads are reported to be very slippery.

Duluth Transit Authority buses were running at mid-morning with the exception of the No. 14 route, which had been temporarily suspended.

Many schools and colleges in the Northland – including all Duluth schools and UMD -- are closed today; see the accompanying link for details.

Fleissner said plow operators are doing their best to keep main thoroughfares passable but have not had time to get to many residential streets.

“With this kind of wind and this rate of snow, 1 to 2 inches per hour, there are visibility problems out there. The wind is filling in behind us as we plow. It’s an ongoing battle,†Fleissner said.

Both the Blatnik and Bong bridges are open with no plans for closure, said Sgt. Curt Mowers, regional public information officer for the Minnesota State Patrol. As of 9 a.m., Duluth has been “unbelievably quiet†as far as accidents and vehicles going off of roads, he said.

The Duluth airport was open, but there were delays and cancellations.

“Our guys are keeping the runway open but two flights have canceled and I’d guess we may see more,’’ said Brian Ryks, director of Duluth International Airport.

Snow is expected to diminish this afternoon and end this evening for most areas.

Here's a roundup of the latest weather warnings and advisories:

• Blizzard warning for Duluth and Cloquet until 6 p.m.
• Winter storm warning until 6 p.m. for Superior, Two Harbors and Aitkin for an additional 4 to 6 inches of snow today
• Winter storm warning until 6 p.m. for Northwestern Wisconsin and Pine County in Minnesota for an additional 4 to 9 inches of snow today. That's on top of 6 to 12 inches of snow that fell in many areas overnight.
• Winter weather advisory until 6 p.m. for the Iron Range, Grand Rapids and Grand Marais for a few inches of snow possible.

Glos, this is a tough pattern to be very confident of 5-6 day forecasts, the storm track will generally remain about where it has been except for tonight's coastal low which is being spawned by the Minnesota mauler of last night. That storm is weakening and moving through Wisconsin, but will split into two systems overnight, the coastal will rapidly gain most of the energy and then head well south of your location by Friday. New England can expect 5-10 inches of snow in most parts (it has already started in Albany NY).

Last night's storm brought several major tornadoes and as many as 10-20 deaths (count is not complete) in parts of Illinois, Missouri, and Kansas. The worst damage looks to be EF-4 from news videos, in Harrisburg, IL which is southeast of St Louis MO and west of Evansville IN. A shopping centre was largely destroyed but casualties there were light as the storm happened around 0100h local time. A Wal-mart was substantially damaged and some staff (stocking shelves) were injured there. Fatalities occurred in nearby housing estates (subdivisions as we call them). There were also reported deaths near Branson Missouri in a trailer park that was hit earlier. This severe outbreak is becoming marginal now that the storm is weaker, but could still drop one or two twisters in Kentucky.

Meanwhile, Duluth Minnesota had an all-out blizzard with hurricane force gusts off Lake Superior (all open due to the mild winter) and 15-25 inches of snow in the region. Highways are closed in parts of northern Wisconsin as well. Freezing rain fell across southern MN, central WI and into parts of MI and ON.

We also had another light snowfall here, 1-2 inches of wet snow was on the ground at 0730h local time here, and this has turned largely to slush but still coats some grassy areas at 1245h local time. Temperature is about 4 C. This disturbance will feed into a developing storm in the western U.S. that will turn into another powerful severe weather event for the central plains and Ohio valley on Friday into Saturday. Glos, that storm may head north of you but you could see snow turning to rain around Monday from its final stages.

I know, the snow I seen forecast for early next week has gone, as I was expecting tbh I know it was too far out. Snow to rain not what I want to see, still hold some hope we might see a decent snowstorm before the end of March?

Thats quite an inland low pressure area i have to say.

Perhaps if it moves towards the E coast then it could form a secondary low.

The lack of Nor'easters this winter has been very annoying.

Has there been a proper one all winter? There was one around the weekend of Halloween so way back in Autumn which delivered alot of snow (not here though) think people thought it was going to be a bad winter to follow? Our biggest single snowfall (30cm), was also back in Autumn towards the end of November, December was ok with regular smaller falls of 5-10cm but since then apart from a 2 week spell towards end of Jan/first 4 days in Feb nothing really in terms of snow.

[Roger J Smith]

There appears to be a high risk PDS (particularly dangerous situation) type outbreak developing later today. It is 0515h CST at the moment so pre-dawn but already some tornadic cells developing in Missouri with all the ingredients in place for explosive tornadic development today across the Midwest and southeast. Rapid deepening of the surface low will create a fast-moving and self-sustaining squall line type situation, affecting a huge portion of the east-central U.S. today. Would be very surprised if this fails to produce numerous tornadoes and a large damage potential -- as the media seem to be in full coverage mode, there may be a chance to reduce the inevitable casualty toll today. It actually looks ominously similar to the worst outbreak ever, the tri-state tornado of March 18th, 1925. Very similar look to the maps (upper air of course implied in that case).

Will post any relevant radars as things develop (peak should be around 21z to 03z but I am expecting a relatively early explosive development phase). Don't be fooled by unwitting references to "very early in season" -- that is bunk, the season is really February to June for the worst severe weather and with the mild winter ground conditions are more like mid to late March in tornado alley already. March is almost as prolific as April in tornado climatology.

It is now 1210h CST and the main event is about to unfold. The storms on the radar posted above are along a frontal wave on the warm front of this storm, but the cold front shows signs of rapid development across parts of IL, KY, se MO and AR. I will post a radar of tornadic warned cells when they erupt (probably around southern Indiana) but the NWS has already upgraded to a high risk and PDS for the Ohio valley and parts of the mid-South. The low is progged to deepen by 20 mbs now to 06z moving from near St Louis MO to Lake Huron. This will be a very active day. I managed to get three hours of sleep anyway.
