Driving down to the West Country (well my wife is driving I should add!) Near Yeovil and the car thermometer has climbed to 7.5C from 2.0C near Basingstoke. Amazing the temperature difference as you head west.

Possibly, although it wasn't specific to just this area. Lots of places had negative DP and temps of zero to one, yet recorded rain or sleet. Odd, but would be interesting to know why for future ref

In particular, it assumes that there's a linear decrase in temperature with height and that there are no troublesome moist/milder layers aloft. You can see these on upper air charts, but they're not regularly posted on here (or anywhere, for that matter).


With this current spell there have been all sorts of complications, as shown by this midnight ascent from the south coast of England (Herstmonceux this morning):

Note how at around 750 feet there's milder air, temperatures are well above freezing and the dewpoint + temperature formula would give a positive result. It was so very, very marginal!

That explains a lot, the snow would need to fall through 1,000 feet of above freezing temperatures before reaching the cold surface, no wonder it rained!


Are these readings available widely on the net?

Which is above average.

Little surprise we get rain or sleet really.

Sleet here, varying from a 5% snow / 95% rain ratio to 75% snow / 25% rain ratio as a heavier burst went through.

The temperature's fallen from 2.8C / dew 1.2C to 1.8C / dew 0.8C since the sleet started.

Roderick avenue and earlier Dorothy avenue.
We had a classic White Christmas December 25th 1970. White out conditions in a blizzard that raged all day. Very deep snow and large drifts. That was 1 week after we moved from Woodingdean. Now that is a snow Trap.

Anyway turned dull dreary and damp here now.

The showers down in the West Country are impressive. As I said it was 7.5C at Yeovil but then after leaving the M5 and climbing the hill on the A361 the temp dropped from 6.5 to 0.0C in the space of about 2 miles! Heavy sleet, virtually snow at times.

Then in Barnstaple there was a heavy hail shower reducing visibility to a few hundred yards and covering the road with ice. I had to hit the brakes to let an ambulance through and the car skidded like it was on ball bearings... all good fun...

Heavy Snow with huge flakes then moderate snow then sleet then drizzle then back to the beginning again. Turns the grass grey in the heavier bursts otherwise just makes everything wet.

Now overcast with spitty cold rain.

3.5 C with 85% humidity under a brisk northerly breeze.

EDIT: Strike that, the cold rain has just turned into wet snow.

The best Snow in this part of the world comes in a Easterly set up. The winter of 1984 1985 and 1986 were fab for deep drifting Snow.

Now it turns to heavy snow which quickly turns all the wet roads, paths and roofs white.
