Thanks for that. Do you know, I had only ever noticed the regular rainfall radar on the Met Eireann website but not the forecast. Hopefully, it'll be accurate this evening.

It does look as though much of the ppn on the radar, at least the lighter parts, is actually nonexistent or not reaching the ground.

The Euro4 looks interesting for here although could do with being a bit further south. Snow opportunities to chase / track at the very least.

Amber may be modified shortly, removing W Country but extending east to SE areas. The small wave low now running along the Cherbourg Pennisula coast will enhance ppn and push it into Sussex/Kent from 9pm. Larger totals likely here than previously modelled.
You can see this process happening in the radar loop.

Temp has now dropped to 0C at Farnborough, just need the ppn to nudge northwards now!

I notice that the auto output has now extended the period of light snow to last through most of the day tomorrow, rather than ending in the morning rush hour. Met O keeps it going till 4pm, with another light snow shower at 8pm.

again, clearly not scientific but is very broadly representative of how it seems to be evolving.

Neil, you called it earlier with the runner low. Some bright echos now blowing up mid-channel due south of the Sussex coast. Looks to be about 75/90 minutes off the coast at the current rate of movement. Moving north but also seems to be feeding brighter echos back north west along the front towards Hants and perhaps even Dorset. Winds here around steady 20mph from ESE and pressure dropping rapidly at 987hpa and a temp of 0.1c/-1dp just 12 miles or so from the coast. 


An interesting evening ahead!

Although there is light snow here in south Dorset I don't have high hopes for disruptive snow. There is though a dusting now.


But looking way down to the south west there seem to be some interesting looking thundery showers appearing over the Brittany area that might come this way.

Temperature down to 2.3c now with a bit of sleet in the heavier bursts of rain. We might just get something out of this, though I'm surprised that there doesn't seem to be any widespread snow elsewhere over here.

The intensity does seem to be diminishing rapidly as the band moves northwards.

As said earlier the pivoting seems to have started earlier which is bad news for those on the eastern side of the area affected. As it turns it now looks like breaking up over Eastern Kent and South Essex, East London and moving more  NW. i would have thought it is still positioning itself well for Surrey, Sussex and West Kent. Certainly not certain about this though, just an observation watching the radar this evening.

Latest from the Met Office posted 2 mins ago, not good news..

Snow, initially moving north & east across parts of southern & southwestern England, the Midlands & Wales, will stall & tend to fragment. Wintry showers will continue in northern & eastern areas.

Meto auto updated and heavy snow from midnight for 6 hours and then light snow until 4pm.

Met, Beeb & others offering hous of heavy here but actually, after a pathetic 10 minutes blowy shower, nothing's happened. Now, I'd like to say the little low risked at on the Beeb forecast has formed and messed up the small detail, or the timing is just a bit out, but I, not a frequent cynic, am starting to wonder if actually, they've got a clue.


 


Here's a clue: skies are clearing.

Indeed it is starting to look like a bit of a failure not just for the western amber area but for anyone to see any accumulations from this. It's fizzling out rapidly.

Roads wet otherwise a non event...still due to the Mass panic sent out by the met office to so many organisations , the M3 and M27 were quiet?...I wonder how much business was lost!

Agree. And with schools closed tomorrow from what looks at the moment out of the window little more than a decent hoar frost.


I suppose higher up things will be different but but it's a very weak squib here at 60m above sea level.


Maybe things will go bang in the night with a lightning show as they mention thundery showers coming up from the Biscay area.
