13th Feb 04:44. This one should be a fairly windy sunny spell. So far
it is a wet spell with overnight showers and quite warm days. I would
have expected clear skies, by and large, giving cool weather and more
sun. Or at least a continuation of the anomalous High we have had since
who knows when.
(Strange that such a singularity should go out without a bang.)

21st Feb 07:17. The weather we are "enjoying" at the start of the spell
for the 13th, aught to be the weather during this one: Deep lows
sweeping in from the west and windy too. Something is tosey turvey here
but I can't see what or where.

28th Feb 00:31. I have come to the conclusion that this sort of spell
(00:00 + half an hour) is a move from a "Col" to a "Trough of low
pressure". But of course things are in some strange turmoil at the
moment so I have no clue really. I'd be looking for a trough creeping
in from a low that is one of a suite of highs and lows that aught to be
surrounding the UK.
Not this time though.

Here's a weather lesson for you, something you may not encounter all that
often across the pond, a classic winter storm combined with upslope flow at
the surface, this spells disaster for areas of higher elevation 7,000+ ft.
Parts of Wyoming and Nebraska will see anywhere from 1 to 3 feet of snow
from this system, could turn into a bad one for the entire northern plains
if it can gather enough moisture.
