    With these temps I'd of expected them to be snow....

    Its 5c here,  not a chance.  The snow risk is from around 3am to midnight tomorrow with the key time here in Dover being Monday morning. Its a 1-2 cms thing on hills, not very exciting in historical terms,,,, but we live in challenging times,,, where snow is becoming ever more vanishingly rare, so on that basis its now something of note! LOL.

    Icon Hi Res is suggesting some mainly light snow cover Tuesday morning in the SE. Sweet spot appears to be SE part of M25 (chaos alert!)

    But...

    The forecast from the 0z GEFS for the upper air temperatures varies from -12 to -4 (8 degrees)! for Monday evening:

    so the above chart is probably at the more extreme end of the range. Caution required.

    looks like some pretty big cells between folkstone and the english channel, could see them from here but nowhere near folkstone to get a good picture of them

    Yes indeed, those cells looked full of menace, glowering and laden with trouble.  The atmosphere had a very disturbed look as I cast my eye southward from Dover Castle this afternoon.  The appearance of the atmosphere suggested to me that there is scope for some rapid deepening and heavy precipitation.  Some place on the north west side of any closed circulation could get quite a pasting in a short space of time - around rush hour.  All quite impossible to be certain of in predictions at this distance of time, but the possibility is there for some mayhem - poss a 1/4 chance, though maybe up to 1/2 over areas with a good altitude to get rapid accumulation of snow.

  4. Evening All.  A classic channel low situation, except its even more marginal than in days of yore thanks to higher SSTs and other background factors.  Much variance in the modelling of the feature, though in the last 24 hours the trend has been to take the feature further north than had been forecasted yesterday.  Clearly areas that benefitted from the pre Christmas fall may again get some wet snow accumulating.  Areas with an altitude of greater than 100m will be better off to catch some snow, plus there will be some input from our old friend evaporative cooling in the heavier bursts of precipitation.  Im expecting rain on this corner but I guess places on the north Downs and High Weald may well be favoured.  Going to be interesting to see if anything transpires across the region.

  5. The latest fax charts are worth a scan through.  Frontal systems portrayed as skimming the Kent coast in the next 36 hours.

    WWW.METEOCIEL.FR

    Météociel propose le modèle UKMO à maille moyenne (1.25 degrés) jusqu'à 144h. Cartes de prévision des précipitations, du vent, des températures à tous les niveaux

     

     

    A set for the scrap books there.

    and Euro 4 is flexing its muscles on the 12z

    Showing 25cms accumulated snow at Ewell Minnis north west of Dover at 5pm tomorrow

     

    WWW.METEOCIEL.FR

    Meteociel propose de manière régulière le modèle à maille fine EURO4 0.04° du UK MetOffice (météo angaise) sur 5 zones (France, Nord-Ouest, Nord-Est, Sud-Ouest...

     

     

    Sheesh.  Seems way out compared to the other models, and Im not sure why?

    Arpege                  13

    GFS.                       10

    WRF MNM             15

    Arome.                   14

    ICON.                       6

    Thought i was going mad then lol!!Arome is a bit more optimistic for snow in maybe parts of East Kent but even then its marginal and i didnt find Arome very accurate in the past.Hope its right though!!

    Hi

     

    18z GFS better.  Its only of bonus value to see some flakes falling.  At the moment Id say its 50/50 but Ive a feeling it will be colder than is currently forecast, so chance of at least seeing some flakes fall to get that winter feeling.
