Martin Stew weather blog: Wednesday

Martin Stew will be on the London Tonight sofa with more at 6pm Photo:

Anyone like me who forgot their gloves on the walk to work this morning won't be surprised to know overnight temperatures were the coldest we've seen so far this winter.

It got down to -7.7 degrees in Charlwood (near Gatwick) and even St James' Park in the city centre was well below freezing (-3.7 degrees).

The cold settled weather we've had over the last few days is the result of an area of high presure. As the week progresses that high pressure will be replaced with a depression - bringing cloud, wind, rain and far milder temperatures.

Friday is looking like seeing the worst of the rain with the weekend shaping up to be sunshine and showers but temperatures up into the double figures.So the big question...

What does that all mean for our prospects of a white Christmas in London? Well the gossip in the MET office (subject to the usual caveats that they don't forecast more than 5 days ahead) is that in London we'll probably miss the snow.

The long term forecast looks unsettled but with temperatures predicted above freezing William Hill's odds of 3-1 to snow on Buckingham Palace roof look like very bad value to me!

Have a great day.
