NAE says turning to rain on Wednesday morning: http://expert.weatheronline.co.uk/daten/proficharts/en/nae/2010/01/11/basis12/ukuk/prty/10011312_1112.gif
BUT .......... turning to rain on Wednesday morning, 6am to midday: http://expert.weatheronline.co.uk/daten/proficharts/en/nae/2010/01/11/basis12/ukuk/prty/10011312_1112.gif
Latest NAE charts (which are moderately accurate) for Tuesday. Pink is snow! 6am to midday: http://expert.weatheronline.co.uk/daten/proficharts/en/nae/2010/01/10/basis18/ukuk/prty/10011212_1018.gif Midday to 6pm: http://expert.weatheronline.co.uk/daten/proficharts/en/nae/2010/01/10/basis18/ukuk/prty/10011218_1018.gif Remember, don't get TOO excited, things may change ..........
Temp here is +0.4c and snow is light to maybe moderate, yet it's settling well on all surfaces. Now I know that the air temp isn't everything, but I do sometimes wonder if my thermometer reads about 0.5 to 1 degree C too high ...........
I'd say more like 50/50, and even then it's likely to be wet snow on low ground (if that) and settling snow the higher you are. But it really is very uncertain.
I think some people need to invest in a barrowload of patience.
Also, don't set your expectations so high - you know that the forecasters are often wrong, so just wait and see what happens.
Not sure which forecasts you've seen but for south and west Wales it has ALWAYS been forecast as light snow, perhaps with the odd moderate or 'heavy' burst. Also worth watching the streamers forming up and moving into south and west Wales right now: http://www.meteox.com/gmapstatic.aspx?zoom=6&type=zoom&x=170&y=224
Based on the 12Z output from GFS and UKMO, we're heading for a real, full-on Blizzard Tuesday onwards.
All might change of course, so don't get you're hopes up (or down!) too much just yet, there's still plenty of room for change.
The models don't know for sure so neither do the good people who are looking at them.
As a rank amateur I'd say that it looks about 50/50 and is still a few days off, so keep watching them models and reading this forum.
Worth remembering that the wind is due to start increasing tomorrow - given the very low night time (AND day time) temps this is going to cause existing lying snow to drift. This will be especially noticeable along roads that border fields where the drifts will form in the hedges and will no doubt encroach on some roads too.
I love snow drifts.
Can't say as I see a 'problem' either, a few doom and gloom merchants around as usual, but I'm just going to enjoy what I've got. :lol: It'll go one day, but most of us have had some fun times from the current cold spell. No complaints from me (although a foot of snow would have been nice and could yet happen). :lol:
Not a good idea to base a forecast on one run from one model, especially when that model is the overly progressive GFS.
And even IF it was to pan out that way, since when does Tuesday count as the weekend?
That's most helpful, thanks. But that's for precipitation from an easterly direction - what happens when we have the forecast borderline thicknesses AND precipitation approaching from the West or South West but still with low level cold air from the continent - wouldn't that give freezing rain or drizzle?
A piddling -5c for us, but it did get foggy so perhaps that tempered it a little, along with the slight westerly component to the wind overnight and perhaps a bit of cloud cover.
