In Birmingham the temp is thought to be 0C Sunday night so may be snow or frost possible. Monday the temp is going to 4C. So it wouldn't last anyway.

15 March 2007
Arctic winds set to bring a wintry spell

Forecasters at the Met Office are warning of a marked change to very cold weather for early next week as Arctic winds bring a sharp drop in temperature and a risk of snow to some areas of the UK.

Northern and exposed western and eastern parts of the UK are most at risk of seeing the snow, with 5 cm possible at low levels. Upland areas of Scotland could see up to 30 cm of snow. The snow may lead to some disruption in the worst affected areas. Daytime temperatures have recently been as high as 19 °C across southern England, next week southern England will have daytime highs of 7 °C with around 4 °C in Glasgow.

Nick Grahame, Chief Forecaster at the Met Office, said, "The snow showers will be heavy in places and the strong northerly winds will make for difficult conditions at times. Melting snow may refreeze at night, with frost and ice being an additional hazard for some."

The wintry weather may lead to difficult driving conditions in the affected areas and motorists should check the latest weather forecast when making their travel plans.

Those with a keen weather interest may wish to see the Met Office Chief Forecaster's commentary.

Chief Forecaster’s commentary

Period Sunday 18th to Monday 19th March

Snow threat

An Arctic air mass will push south during Sunday, with deep instability bringing heavy snow showers, enhanced at times by organised troughs. Exact timings of organised troughs still remain uncertain at this stage.

The 1,000-500 hPa thickness will fall below 516 decametres (remarkably low for the time of year) by the end of Monday, even in the south of the UK. Couple this with sea-surface temperatures of between 1.5 and 2.5 °C above average and we can expect deep convective instability and heavy snow showers in places.

The main areas at risk will be Scotland and Northern Ireland at first, but there is also a significant risk for western and eastern areas of the UK exposed to the northerly winds. Conditions may be conducive for the formation of polar lows.

Winds will veer slowly during Monday, becoming northerly by the evening leading to an increasing number of snow showers to affect North Sea coasts and adjacent land areas later.

Significant accumulations are expected above 200 metres and temporary accumulations at low levels.

Ice threat

There is a moderate risk of ice associated with areas affected by earlier daytime snow subsequently melting and then re-freezing after dark. The risk of ice is primarily for Scotland on Sunday morning, but extending to other areas thereafter; still too early for the detail on this.

Wind

Generally very windy with gales in northern and western areas of UK, with a low risk of severe gales in exposed places.

'organised troughs', 'deep convective instability'??

All I want to know is if it's worth dusting off the sledge again!

Where are these cold winds coming from? I thought we were all warming up around the poles!

So nothing for London? This place is boring. Always sun, sun, sun. Unfortunately its no Barcelona. Saying that, probably for the best. A bit of drizzle and they all get over-excited

FLINTOFF · 16-03-2007, 5:19 PM

Sorry but hope we get none

Well there is still time to change, but all I see are blue skies broken by white fluffy clouds. A breeze and the weather is still nice out. I want snow too!
