A few snow showers overnight have left a covering over the grass.
Temperature has stayed around +1.8C all night meaning roads are wet
and clear. Veil of medium frontal cloud passing to my south with a
few showers to the north. Wet-bulb freezing levels have risen to
circa 550m asl due to the frontal plume but set to fall again later
today.
Postbridge is up to +2.7C now in the warm plume but webcam is
showing a snow cover.
0800
Sleet falling from medium cloud. T+2.2C. Peak of mild air will be
next couple of hours.
0900
Still sleeting, T+2.2C and steady. Just been a drive around and it is
snowing at 400 metres but not settling on the road which is wet.
Extensive thin cover of snow which looks to be more substantial above
450 metres. Went down to the shops at Bovey Tracey which is just 30
metres above sea level and it was cold rain with temperature +4C.
Seemed wrong being there with ice on the car roof!

Sleet showers have continued this morning despite higher dewpoints
(circa 3C). Practically all rain at one stage. Now more snow in the
mainly light showers as the colder air in depth starts to dig back in.
Fascinating weather!
1150
Crazy weather!
Showers have stopped and temperature has rocketed up to +5.5C which is
warmer than this time yesterday.
Yet ..... in 6 hours time wet-bulb freezing level is forecast to be
250m asl (i.e. below my house) and snowing. The line moving south down
the Irish Sea (same line that has given Norman and Manchester a dumping
on the pivot) is taking on cold front characteristics, so I guess it
will be that set to cause the decrease. Pressure continues to fall
relentlessly at 986 hPa.
Ah sun is out time to put on my shades and have a coffee on the terrace
in the balmy conditions. Needless to say, remaining lying snow melted
rapidly in the past hour in the Haytor area.

The drama continues - no sooner that I went outside when it started to
rain. This quickly turned to small hail and then a few minutes later
snow, medium sized flakes. Snow falling into a cup of coffee doesn't
half cool it quickly :-)
Now sun is coming out once again but the skyscape is completely
different to this morning. The medium cloud has gone and there are low
winter Cb tops visible. Temperature is falling quickly and is back down
to +3.8C after a max. of 6.0C just 15 minutes ago!
This is why I love Dartmoor weather so much, we actually get weather,
sometimes four seasons in one day. What next? Bring it on :-)
1420
Moderate to heavy snow. Vis. less than 500 metres. Really coming down
hard and blowing blizzard-like in the strengthening wind. Accumulating
quickly and rapidly turning Haytor white.
T +2.5C and falling quickly
1615
Heavy hail depositing 1cm followed by heavy horizontal snow. Main road is
covered in snow 1 hour after gritter went through.
Temp +0.3C.
Now clearing up with large areas of blue sky. That's it now for a wee
while!


2130
Light snow showers have continued this evening. 1cm full cover, road slushy.
Although temperatures are still over 1 degree above freezing the top of the
snow has frozen.

Going to be interesting tonight when that polar low comes down. It has a
history of thunder and very heavy precip. Above 300 metres in SW England
thundersnow is a possibility.
It seems to be tracking further west than the models suggested at midday.
Shades of Feb 2009 when the WBZ was over 600 metres asl initially and yet we
still got 9 inches of snow in 4 hours. Convection is a powerful force for
bringing freezing levels right down. Having said that there is a lot of rain
being reported at low level stations in Northern Ireland.

Arrived back to Blackheath just now to snow falling. I'm easily pleased in
my middle age as I'll happily take that for the winter.

Interesting that "the swirl" is only really producing rain....at the
moment.
