I don't know how to word this correctly but here goes
How does a cold pool come about and what sort of temps can be expected if
one arrives here this month?




This is an excellent question:


It is quite straightforward really. That is assuming my description is
correct. A cold pool forming from a high pressure system is created soon
after an intensification of the high pressure to the east or north east of
the UK. This would cause the high to pull a wedge of cold air from NW Russia
in our direction. This cold pool would accumulate over the UK until the high
pressure weakened sufficiently to allow warmer west or sw winds to remove
it. In rare occasions the cold pool would sit until it was reinvigorated by
a resurgence of the high or even a shift in the high pressure to an even
more advantageous position.
In most cases though the cold pool will sit until the air warms in its
lower altitudes giving a few good night frosts until such time as the high
declines and then the cold pool is replaced by milder air.
The sort of temperatures I would expect in a cold pool over S and
Eastern England in mid November would be daytime maximums of 5C or 6C and
nightime temps of -2C to -3C.
I hope my answer is OK.

Regards, Gavin.
