Euro4 has overdone these accumulated snow predictions near the coasts recently so not saying its gospel, however by 6pm tomorrow it shows this, inland and higher elevations should do well as usual.
That Euro4 should be banned for snow charts! Unfortunately will probably be another sloppy mess save for very high ground.0 -

Going by this winter. That's nature about to de-ice us before the snow arrivesLooking at satellite animation and there appears to some sort of front or more organized area or cloud and I would imagine associated precipitation about to arrive on the West coast. Could be just cloud but in any case there's a good area of convective showers to follow. https://en.sat24.com/en/gb/infraPolair

could be some sleet and snow showers across the country tonight. A few of the charts have them making it to the east as well, but I wonder how much of them will survive the journey intact.
Dew Points heading in the right direction.
Temperatures still a bit high, hopefully if the showers make it here later the temperatures will have fallen by a few more degrees.

First trough line (or enhancement of precipitation) approaching the west coast. Won't be sleet or snow to lower levels in coastal counties there yet but as Gonzo said showers turning increasingly wintry overnight with falls of snow toward morning particularly inland.

Come on Euro4, be right for once!
It’s on steroids tonight. One of GL’s soundings wont be long putting it in its place.0 -

Sure is Sleety_Rain . Good forecast below from Convective weather, will stick it in here as very much part of the cold wintry day tomorrow. Showers galore with hail hopping off the ground, looks like we could get sparks inland as well as along Atlantic coasts.
Day 2 Convective Outlook
VALID 06:00 UTC Tue 25 Feb 2020 - 05:59 UTC Wed 26 Feb 2020
ISSUED 22:08 UTC Mon 24 Feb 2020
ISSUED BY: Dan
Broad upper troughing covers the British Isles on Tuesday, sharpening and sliding southeastwards during Tuesday night. The associated cold pool overspreading relatively warm SSTs (and diurnal heating inland!) will generate a few hundred J/kg CAPE in an environment with very steep mid-level lapse rates. Numerous showers are expected throughout this forecast period, primarily focussed over western areas initially but developing more widely as the upper trough slides southeastwards with time. Several shortwaves will also provide the focus for more enhanced activity as they drift southeastwards in the mean flow.
One such feature will be close to western Ireland first thing on Tuesday morning, drifting towards Wales / SW England by midday and then across southern England / Midlands during the remainder of the afternoon and evening. This will be strongly forced in an environment with strong shear, helping organisation of cells and it is quite like sporadic lightning and hail will occur with this activity. Ahead of this, a strip of vorticity coupled with diurnal heating may allow a separate line/zone of showers to develop and drift across the Midlands / southern England / East Anglia / SE England during the first half of the afternoon, and this could also produce some sporadic lightning.
Another shortwave will enhance shower activity towards NW Ireland on Tuesday evening, eventually approaching western Scotland during the early hours of Wednesday. Away from these more organised features, random scattered showers will still occur capable of producing a few isolated lightning strikes - particularly over NW England. Strong, gusty winds will be possible with the most intense showers - particularly in southern and western Ireland towards SW England, and it is in these areas that an isolated tornado may also be possible. Eastern Scotland and NE England will see very few showers, and could stay largely dry.

Here's the source of the 250-m air that arrives at Mace Head tomorrow evening. It will have set out from Baffin Bay 72 hours previously, with a more northerly and hence shorter sea track than previous similar outbreaks.
Most should see snow showers as the coldest 700-500 hPa air gets in tomorrow afternoon and evening, with a many white cars by Wednesday morning. This level warms considerably during Wednesday afternoon, so shower activity will be dampened by then.

tomorrow looks very showery indeed, in places prolonged showers.
showers already in the east by early morning.
showery all afternoon and into the evening:
showers making it to the east even tomorrow night:
Hirlam wants to bring a spell of sleet and snow across the south and south-west tomorrow evening.
Bitterly cold tomorrow afternoon, temperatures will struggle to get to 5C.
Uppers of -7 to -8C
fairly raw wind chill tomorrow which gets more noticeable as the day and evening goes on.
Quite windy at times with gusts between 60 and 90km/h
Tomorrow has the potential to be the most wintry day of the year so far. I don't think there will be much in the way of lying snow away from high ground until after dark. Could be temporary dusting in places during the daytime.0 -
