Currently light to moderate rain, +0.3deg C, slush has compacted on my

even on the side roads.

After I last posted it turned to a mix of rain and sleet, with another
brief spell of snow just before 1700.
At the moment of the solstice (1747 apparently) it was wet and cold.
As appropriate as any I guess.... I'd be willing to bet that for a
combination of rain and cold, this could, appropriately be enough, one
of the wintriest days of the winter in these parts.

The rain band moved West late afternoon before returning Eastwards in
the late evening - but as rain with just a suspicion of sleet,
stopping after midnight. However, the rain has failed to clear the
slush from pavements and side roads, which remain treacherous. Two
miles E and S of my location, the sleet and snow failed to stick at
all, there is no slush.

I suspect that even the small difference in elevation (40m) made a
difference, and the intensity of the precipitation which seems to have
been a bit less just to my East.

Midnight to midnight, I recorded 17.4mm of rain, sleet and melted snow
(collected in the guage) and most of it will have fallen during the
heavy sleet and snow in the afternoon. If it had been one degree
colder, I might now have been reporting a snow depth of 6 to 8 inches.

Temperature is now falling slowly (+0.5) and the remaining slush will
I am sure be frozen by dawn.
