  1. All models bring through showery rain/sleet/snow around the centre of the low tomorrow through the Midlands. Looking at the data - dew points hovering between 0-1C will likely mean sleet/snow in heavier bursts 100m+. Generally snow anywhere 200m+ looking at the freezing level. Looking like mostly rain below 100m.

    Unlikely any settling snow will last below 300m. Can't rule out temporary accumulations if precipitation is heavy enough but ultimately it will be another dreary damp day for most. 

    GFS well out on it's own with the band of snow for Sunday.

  2. Love snow, but as Winter nears Spring I become less interested in it. Don't really enjoy the snowfalls you get in March/April where it melts by mid-afternoon as per last year. Prefer the early Winter dumps where the snow becomes crunchy underfoot and makes you feel like you're in the baltics for a few days.

    Mind you, it is pretty seeing colourful crocuses pushing out of the white blanket. 

  3. It wasn't meant to be. No entrenched cold before today, temperatures haven't gone below freezing for most places, ground temps are higher than normal after a very mild week and dew points were about on the line as you can get. 

    You had to question the models over the past few days that it predicted anything other than what we see today.

    That's not strictly true though, air temperatures still need to be conducive to allow that to happen. I've seen plenty of snowfalls where the opposite occurs because the conditions aren't right. One of them being last March. 

    The reason snow settles on wet roads is because the atmosphere becomes favourable eventually, like due to evaporative cooling or a change in the direction of air as examples. 

    The Met Office clearly see this being snow to sleet/rain with little accumulation for most places below 200m (where conditions above that in the air are conducive of significant settling snow). 

  5. Big difference actually when it comes to the dew points - degree or so down on the last run for the same time. A shift of about 30-40 miles southward which indicates the cold is undercutting a bit more than originally forecast. 

    Incredible thermal gradient though. 10-12C along the south coast 0-2C across the Midlands. Spring to Winter in about 150 miles.

  6. Any significant snowfall will rely on evaporative cooling. Most models drag the dew point down from positive values to near freezing as the band moves across - the heavier the precipitation the more this will have an impact on conditions at the surface and the longer we all see snowfall. 

    Most models lower these dew points to near favorable conditions but many are just on the wrong side of the border.
