Can't see much action in this thread in the coming days in terms of talk about the days cold weather. Far from it, all we will be able to talk about is wind, rain and cloud, oh and nice mild temps with double digit maxes, though I am not expecting anywhere to see anything higher than 12 degrees, and here in Cumbria will be probably just manage to squeeze a couple of days at 10 degrees. So although mild, nothing ridiculously mild on the cards.

I fear we will be talking about localised flooding instead of snowfall.

But I anticipate this is going to be a brief blip and next week we will be talking frosts and snow potential again..

As for snow, well we had some heavy snow first thing which left a slushy cover..

Wow, barely a cloud in the sky! Didn't think it would be this sunny today.

Is anybody home?

Milder, But For How Long?

Over the next few days the weather is going to turn milder, however there will be alot of wet and windy weather around. Although we are not done with the snow just yet, as the next front to sweep in from the Atlantic may well bring a brief period of snow to some areas.

However before that Northern areas will see increasing amounts of sunshine, however further South i think it will remain cloudy with some light showers possible even these will be far between. As we move towards the evening hours a front will begin to move in from the Atlantic, however skies will be clear and this will allow tempertures to drop and a slight frost may develop. The charts below are from the 06z and show the tempertures for 18.00 and midnight.

The rain will turn heavy across Ireland for a time, turning lighter later overnight. The rain will be at it's heaviest across Wales, The South West and later Northern England and Scotland.

However as the rain hits the colder air sitting across the Scotland and the far North of Northern England it may turn to snow, more so across Scotland, Scottish Hills and the Hills across Northern England. Snow will even possible across lower levels for a time. Amounts are very uncertain could be alittle bit more or less, however i would not rule out 2-3cm to some localized lower levels and as much as 5-8cm across the hills. Any wintery weather across Northen England should turn to rain fairly quickly, elsewhere is going to be a milder night with rain (heavy at times) across all areas of the UK. Heavy rain coupled with last night's heavy rain and snow-melt could lead to some localized flooding, there are a number of flood watches in force across the UK and can be found here http://www.environment-agency.gov.uk/homeandleisure/floods/31618.aspx

The charts below are taken from the 06z precip type charts.

As we move towards dawn the tempertures across Scotland will be on the chilly side, so ice may be a hazard first thing. However rain will still be sitting across most parts, and this again will be heavy towards the West.

However the rain should clear East towards dusk, although it will leave some sharp showers in its wake.

The milder air should reach all areas of the UK by the end of Thursday, and temps will be 8-13c. For the rest of the week its looking wet and windy at times, however there will be a couple of dry windows at times. However with all the rain that's due over the next week or so flooding is expected.

Im suprised how cold it is outside, car temp has it at 1c. The windscreen was also frosty. So i might see something wintry on the very front edge.

Whats your temp?

[Thunder Snow]

Currently -1 here and a dew of -3, i could well get something wintery from this.

[Backtrack]

Whats your temp?

Dunno.

One station says 3.3C but that needs a battery change. Been saying 3/4c for ages. Others batteries have ran out and the one upstairs isn't accurate till 3am. xD

[itsnowjoke]

dewpoint -2c

[Lancashire Lass]

I could be wrong but I'm pretty sure it's 0C so you're definitely on the right side.

[The Yellow Snowman]

i remember someone saying if you add them up and they make less than 0, precipitation will fall as snow.

[Lancashire Lass]

The band of rain should be reaching us within the next hour or so.

[The Yellow Snowman]

the band of precipitation is probably less than 20 minutes away now. We will see soon, i hope it falls as snow, even if it doesnt stay around for long

Lancashire Lass beat me to it

No, generally <0 is needed for snow, but many other factors determine the likelihood os snow.

As a General rule you need:

-At most 528 DAM line ( This can be flexible in heavy precipitation, but any lasting snow at low levels really generally needs this)

-At most -5c 850's ( Also flexible, but for anything decent at lower levels, this is a must)

- The Zero Degree Isothern must be low enough. I believe its something like 300m for lower levels to see snow

[damianslaw]

Its been a lovely day here. Lots of sunshine and clear skies with light winds, though it was quite cold. A quick frost developed this evening and we are currently hovering around 0 degrees. Depending on when this front arrives we may well see some temporary heavy wet snow before it turns to rain.
