Still expecting something? Rather borderline at the mo perhaps

Temp dropping - 2.2c and dp 0.2c

.... I know: with this flow, we could be in for several hours of rain,
some sleet, but little else. We'll need the flow to come from the
lower dew-point north and get entrained in the circulation of this low
as it forms: we could be in for a wait!

A case of 'testing the forecasters' nerve', a phrase used in another
context many years ago.

This low is obviously dragging in some milder air off the Channel.

As I've suspected all along... certainly for where I live.

I think it's pot luck if we'll get rain sleet or snow here... probably
all of them at some point in the next 24 hours but any snow
accumulation down here will I think be low and slushy (from past
experience and Martin's reports)

We shall see.

I'm reliably informed it's currnetly snowing near Bournemouth University but
not settling. Don't panic ;-)

Probably worth noting that here at an altitude of 300 metres the precipitation
during the past 24 hours has all fallen with the temperature around -1. That
equates to a sea level temperature of about +2. I guess that precipitation at
low levels witll be right on the snow/rain divide.

.... interesting: as you know, I can *see* the a/c taking off/arriving
from here ... all we've had is rain (now stopped) and the
temperature/dew point structure wouldn't support anything other than
rain!

Or how about dragging in some lower-dewpoint air from the south? France
looks a little chilly at the moment.
