.... (03/0740Z JAN 2011) just a bit of 'ground truth' to confirm that the
PPN belt indicated on the latest radarnet animation has given us a miss
- looks like it's developed as it ran further inland - and may also be
evaporating into the drier low-level air.

Martin, 0800UTC, Here it's dry and quite mild-feeling: +1.3C, DP -1.7C.
So if there's ppn to come it may be sleety/snowy, I guess.

.... (03/0810Z JAN 2011): a very few 'flakes' of melting snow floating
down when I poked my nose outside - from leaden-grey skies; no impact
surface/visibility. OAT= +1.3°C // DP= -2.0°C.

According to RainToday it has been snowing for the last two hours where I live
yet I haven't seen a single flake.

.... (03/0910Z JAN 2011): little change - a very few 'flakes' melting
snow (about 2 or 3 per minute) with no impact surfaces/visibility -
latter is excellent. OAT= +1.7°C // DP= -1.9°C.

very slight PPN ceased, certainly nothing falling by 1115Z and it may
have given up well before then. Cloud base higher/cloud thinner (BKN SC
under BKN AC).

Surfaces damp. Cloud looking a bit convective.

.... (03/1600Z JAN2011): OAT= +4.3°C // DP= +0.4°C: continuous slight
rain past hour; looking at the Hurn DP ( a few miles to the south of us
/ +1.7), I think the curly occlusion must be somewhere down the Poole Road!
