Looks a bit chilly on Wednesday - low dragging in precip and rainfall
off the north sea, temps of 2c! No doubt some overcooking going on but
a bit of shock to the system to come potentially...

Its an interesting one Richard. Unfortunately, I'll be away to see it.


Good. It really is interesting and very unusual for October. I've been
commenting all day on this on http://totallyweatherandclimate.co.uk/
Have a read. You'll get some decent discussion on the possibilities
too. Not like you've just encountered here.

It is not that unusual for the end of October. In the 1960s I always looked
forward to seeing the first wintry showers and snow on the pennines end
Oct/early Nov. Last October snowfall here on Dartmoor was as recent as 2003.
It is going to be a cold one for sure. Arctic blast straight from the pole
which does seem cooler than normal going on how far the 510DAM thickness is
forecast to come south and the 492DAM on the charts earlier. What does it
mean for the UK, in a word, cold. Frost at night and showers of rain sleet
or snow. Most of the snow will be confined to northern Britain (Manchester
northwards) and hills further south (above about 800 feet), and a fetch off
the sea is required too, the SE could stay dry, sunny and cold. Having said
that the situation is conducive to deep convection and polar low formation,
clearly any prolonged precipitation will lower the wet-bulb freezing level
and bring sleet and snow down to sea-level. My personal view is that western
areas are more prone to these developments. Dawlish Paul in our neck of the
woods whisperSW England/whisper we may see sleet/snow falling down to
150m asl but it will mostly be confined to 300m (1000 feet) asl and above
where it might lay for a while, most precipitation on low ground will be of
rain or hail as the windward seas are still quite warm. Having said that
convection could be deep and I would not be surprised to hear thunder.
Interesting week ahead. If we do get a polar low down the Irish Sea, please
don't try and get to Haytor for the snow, you won't make it, unless you walk
:-)

Wintry cheers,

Will (Haytor, Devon, 1017 feet asl)
