I'm back. a finger of precipitation has fed northwards from the channel, of all directions and sources, proving that a low formed today over london and has slipped south westwards, or has re-emerged there. The finger is bringing snow with it to parts of west sussex and surrey. There is a similar finger further east, in Kent. Update a3 13:43: those fingers of snow are expanding and one has reached north to london
Dunno but precipitation in the SE area is now circulating anticlockwise, over a wide area, around ... London. Is London the temporary centre of a shallow low, which, earlier, was centred south of London?
Looking at the Met Office radar again ... still indications of a low or trough in the far SE, centred on where there is little or no snow at present. Snow on the East Anglia coast is edging north, while off the coast of eastbourne it's heading ENE or EN. In Surrey it's edging south well into west sussex. Or is all this to do with a France Low; e.g. or a perturbation of it...
Ah, that's probably what i saw via the radar - when going back in time a bit then to the present ... Anti clockwise movement, with the centre of that south of london/north of the sussex coast.
OK, thanks. cold winters can clump together ... why not cold springs. i remember frozen snow flakes on the ground in the winter of 1956. i was very young. Then came 62-63, lol! Magnificent.
Look at the the met officer rader ... go back in time from then to now. You'll see the direction the snow bands/showers are movingin the SE - which is anti clockwise, with the centre of the bands between london and the sussex coast. That centre might be a low pressure forming.
Both. you can track it here: https://www.metoffice.gov.uk/public/weather/observation/rainfall-radar#?map=Rainfall&fcTime=1521226800&zoom=5&lon=-4.00&lat=55.01
Looking at the direction [anti clockwise] of the snow radar returns for the SE ... it does look as if a low is forming over the south east [between london and the sussex coast].
At 1.30pm today ...OC right by the sea in Shoreham, -1C a few miles inland. Crazy temps. Snow settled on the hills and trees. Incidenally, is a trough or low forming on or off east anglia?
