  1. looking further ahead for more Snaw chances.....as mentioned by @Kirkcaldy Weather a day or so ago, the MJO is in prime phase and forecast to move from phase 7 to 6 then back to 7 again. This gives us more chance of an Atlantic ridge or Scandinavian blocking. The NAO has a much greater % chance of being negative in these phases however the models are not showing this on their output, why? I personally think the SSW downwelling and the effect of the Canadian vortex lobe draining into the Eastern US has trumped standard pattern drivers and thwarted our chances somewhat of the "standard" pattern emerging for the current MJO phases. Thankfully the Canadian Vortex has now started to recede somewhat and will have less of an influence downstream into the Atlantic. So I suppose that begs the question will things improve for us in terms of overall blocking pattern and snow potential? I'm thinking yes and the models will start showing this potential by the middle or end of next week. Teleconnections this winter so far have took a bit of a beating as things have not worked out quite as expected and the overall pattern will need to be carefully analysed to determine why. Even right now the torques and AAM are doing strange things, ~Mountain torque remains high with frictional torque low forcing AAM for longer than expected given the overall momentum budget, things should have started easing off a bit allowing the atmosphere to slow its pace (Imo this then allows for a more wave jet stream allowing the blocking patterns to take hold) This doesn't mean we should dismiss teleconnections as 9/10 times they are the best indication of how an overall pattern longer term will pan out. So a few more days of modelling miseerableness then back to something of a bit more interest. 

    Dont get me wrong here we have done ok in terms of snow and cold, even the far south of the UK has seen some but the potential is there for more and us low level Fifers are snow starved and want some Snaw!!

    Some charts for consideration while reading the post.

  2. @Kirkcaldy Weather Scandi heights are going to become a more prominent feature in the next few weeks I feel. As you say the MJO phase is favourable for some HLB. Hoping for some serious snaw this month as from the start of March until mid June I will be in Texas for work and will miss any March madness here   Will be keeping a keen eye on the Radar this evening on the nightshift and I think there will be a chance of some fleeting snow showers anywhere from Aberdeen down the coast to the borders.

    Surprised no mention at all in the forum about expected low mins tonight, BBC reckoning possible -15 degrees in Grampians. Would be good to know of current min temps.

    Kirkcaldy snow shield fully operational 2.6 / 1.6 C InbornBruisedHalibut-max-1mb.gif  good to see the likes of @Blitzen @Benvironment @Snowlover2 getting in on the snowy action (and all of you lot further west too of course) 

     @ghoneym  what's it like along in costa del Methil same as here id suspect  pish.thumb.jpg.cdf525f3ae65966ad8e7ca7eac1ecc74.jpg 

     

    Were in Leven nowadays but obviously close enough to Methil but just rain here today, I was working at Cowdenbeath and we had quite a decent snow shower this morning for a few hours from 7 to 9, didn't last long and turned to mush by midday

    Despite what the radar says, it has been raining in Glasgow during the past half hour.

    Its wet bulb temperature, its too high. It needs to be at freezing or below. Quick math - say its 3.5 degrees in Glasgow centre - relative humidity 91% currently (from netatmo live map) - Then dew point is 2.2 deg C - to work out wet bulb  we need the dew point depression so - temperature minus dew point  = 1.3 - you then divide this number by 3 = 0.4333 - and subtract from the actual temperature - so your sitting at approx 3 deg C wet bulb temp. Not cold enough for snow.      

    This is the problem our sothern friends will have tommorow also.

    Could even bring a bit of snow down to the Edinburgh area. I guess we'll find out tomorrow where exactly it will hit.

    Coming back to the showers moving in at the moment, i'd be really surprised if nothing reaches here. There are a lot of them moving in, and they are heading for the forth and towards Edinburgh from that direction. Will going over water again pep them up a bit?

    The direction of travel is very important in what your talking about, probably a more NW flow rather than a direct Westerly flow.  you've probably heard of a Squall before and that's short  sharp burst of wind and precip that last minutes rather than seconds. So It is possible yes but like a say direction is important for a strike on Edinburgh area.

    I work at the jetty at Braefoot Bay on the ships occasionally and the Squalls we experience during winter can be excruciating, yet 6 mile away in say Cowdenbeath, they have very light wind, light precip.

    on a Serious note what do you guy and girls think the polar low will bring for us? Blizzards?? just so i know to get snacks and beers in to sit and watch it all unfold.

    Short lived, but has the potential to bring strong winds, a true polar low is wind speeds above 40 mph I think, will have enough precip to give a good dump on its paths outer edges if I'm not mistaken.

    Just seen this on Facebook, not sure what you all think?

    A think someones been on the glue over at GBW weather, if that's an accumulation chart then no chance. Most of any snow falling south of Northampton / cambridge will thaw pretty quickly as the front moves through.  North of that maybe a chance.

    The Welsh Eastern coast

    Costa del Llannerch-Y-Mor on the East coast of Wales ......

    Anyway, whats the script with the ECMWF license stuff, I thought if you pay for the service you can share certain model graphics on certain parameters.  Think I read 5 a day or something like that?

  10. Here is my take on Tuesdays snow events using that trusty old Swiss HD model. 

    By Tuesday morning the centre of the low pressure system is out in the bay of Biscay, West of Nantes.  Precipitation from the front reaching the Welsh Eastern coast is just starting to show.  The charts can be moved on in 1 hour time slots but I have done it in 2 hour time slots here to save posting too many charts.

    The snow line continues to track in a south easterly direction throughout the day.

    Snow depth totals by Tuesday evening then. Just for bants.....

    Wednesday could be an interesting day also with freezing for forecast across many parts of the UK from midday through to early evening, again, making rush hour and driving conditions extremely hazardous.

    For my Scottish comrades, we await Thursday as I think this will bring some decent Snaw for us from the borders up through the central belt. Here's hoping !
