The dew point here right on the coast is currently -1.8℃ but this is forecasted to rise as the Lp slides down the north sea, hopefully for those on the coast (myself included) see snow and not a wintry mix.

I think we've just hit an all-time low..Ha ha.!! http://www.southshields-weather.co.uk/Today%27s_weather.htm

Radar now showing ppn starting to develop this side of the Pennines/Cheviots, unless its radar clutter..

It would have to be out of thin- air judging by the radar..!! © Netweather 5min radar V4

Yeah, made me chuckle when I read your post last week.."what a waste snowing into puddles"

I really wouldn't despair to much regarding wet surfaces. If the showers become heavier and frequent as forecast the snow should stick.

Snow right down to low levels so early. Snowing 'quite' moderately but looks worse than it is in this very strong wind.

A term used quite often in the states, seen it used by NOAA.. I'm another who dislikes that wording for low pressure.

I can't understand why SM has said poor charts for longevity of this colder spell compared to previous runs as the GFS ensembles I posted yesterday clearly shows the 'colder' period ending around 4/5 Feb. The latest GFS ensemble (00z) does show the period after the 5th trending slightly 'warmer' than yesterdays but with scatter like that I'd not like to call what the conditions will be like thereafter. There's 2-3 members now calling sub -10℃ 850hpa which weren't present on yesterdays ensemble.

The 06z GFS Ensemble showing a fair bit of PPN but as we know determining where it will fall will come down to nowcasting but with the T120 fax chart showing fronts and troughs running down from the north (Arctic source) so I can only imagine snow/hail from these. T120 fax chart. 06z GFS Ensemble for my location here right on the coast Precipitation rate.. although pretty unreliable at this range

Around 2 this morning we had a thin (3-5mm) but 100% covering of snow, shame the surface wind direction changed and started coming off the sea from a NNE direction pushing dew points well over 0℃ and sleet/rain was the end result.. Oh well looked pretty at 2:30am..

Looking good for a decent snowfall evening/night (away from immediate coasts, although a wintry mix here) as an occluded front and a small trough push south through the region. The 'warm' sector (-5℃ 850hpa) over the north sea extending towards our region has been 'watered' down a degree or two so trending colder. For some reason I cant post charts.

Pretty accurate on the timing but a bit out on the 'thin band' bit, its actually a lot wider than suggested from the NMM Hi res. © Netweather 5min radar V4

Cheers Paul. Wow what a difference, dont think Ive seen so many arrows indicating wind direction, I suppose thats due to the higher resolution?

Oh sorry Paul, wrong thread but whilst Im here, the V4 radar GFS data overlays aren't showing.

Hi Paul, any news on getting this issue resolved? Cheers.

Well we can all say a big farewell to the GFS and welcome in the GFS parallel, as from tomorrow it replaces its older brother for good. Tis pleasing to cold fans that the parallel shows the best of any cold/snow chances.

Give em one of ya 'chilli choking pepper belly curries LG.. Thats proper 'central heating'..!!

Did anyone watch Wild Weather with Richard Hammond on BBC one last night? A fascinating insight into the dynamics of wind where Richard Hammond visits the Wind Engineering, Energy and Environment Research Institute in Canada to see the worlds first hexagonal wind tunnel that can simulate different wind conditions such as tornadoes with help from its 106 massive fans. http://www.bbc.co.uk/iplayer/episode/b04tqghf/wild-weather-with-richard-hammond-1-wind-the-invisible-force

What a year that would be, witnessing all of that weather fury in a space of 12 months.

That is a fine shelf indeed, much, much better than the one Alabama got yesterday and that was a 'moderate' risk..!!

According to ESTOFEX there's a small risk of tornadic activity over southern areas overnight. S-UK however is placed next to the still deepening cyclone with strong S/SE-erly flow. Models differ in degree of CAPE build-up, but there are some hints that even an isolated near-surface based thunderstorm can occur during the night. With maximized LL shear along/just south of the synoptic front an isolated tornado event is possible. Marginal hail and gusty winds accompany this activity. http://www.estofex.org/ Looking at the charts I believe this is through Sunday night into Monday morning.

Torrential downpour accompanied with one bright flash of lightning here. A wet early evening in prospect hopefully with thunder, hail and the odd tornado. Anyway to set the record straight this is a 'mini' tornado.

G'mornin Paul, when I log into netweather I get this on the home page. Apart from that everything seems fine. Working now..

Yes and its not very interesting, lightning resembles someone turning the lights on and off very quickly and the thunder is barely audible.
