South East and East Anglia Weather Discussion Sept 2020 onwards
SMU replied to Blessed Weather's topic in Regional
Significant upgrade on 12z GFS as the -8c isotherm is modelled about 100 Miles further south This is Weds night but Tues is the same -
Big swing south on the -8c isotherm at T54 on the GFS ... More alligned into Norfolk & essex Then @60 spreads SW means more in the way of snow
-
ICON key > good with the greenland heights > probably a bit over blown on the low...
-
Good Afternoon ICON improves with more cold over the UK ( sub -6 ) but also a negative tilted high in the atlantic & less 'warm' pocket influence from that low over benelux

Really sorry to hear that...... -
GFS day 7 mean stays at -6 now where as before it was only half covering the UK, also lower heights... Also, already the GFS backtracking on the speed & 'positive' tilt on the high as it sharpens up. As ever UKMO is the model to follow...
-
GFS 06z trends back towards the UKMO with a larger pool of 850s impacting the UK reducing the non snowy shower periods especially in the SE
-
ICON 120 does being that band of snow into England from the East... Far to many people worrying about the end today when its not even started ... Same old story on here...
-
-
ECM mean @96 V the operational shows that the op was nearer the top end of the table for 850s especially the further south you go- I think 96-120 the ECM got another downward drop of 1c in it...
-
At least it will dry > has *Never happened* Get to the days & there will be heavy showers kicking about....
-
00z...
-
Just waiting for WX charts to update Interesting to see how far south the snow is on the eastern flank Maybe some imaginary 20-30cm snow depths by then
-
Snowstorm for Wales / Midlands at 240...
-
Ha no sense of humour.. 216 ECM crucially shows residual heights over greenland which is very important in sustaining the cold spell > which is somewhat expected given the eastward momentum is rapidly decelerating...
-
-
As said its not going to drop.... Look at the nose... Look south for the squeeze up for energy flushing the continental cold WSW
