Default [WR] 30/1130Z NOV West Moors/E.Dorset

... (1000Z): PPN past hour has been rain/snow mixed (very light) or
drizzle as temperature has slowly risen ... currently OAT = +1.3°C.
All earlier fragmentary lying snow has melted - all surfaces damp.
Current -RASN. It'll need advection of colder air, or sustained
heavier PPN to give us anything dramatic I suspect.

... (1130Z): PPN ceased not long after above report - cloud
character becoming more convective - shallow Cu, underneath thick Ci
and residual Ac. OAT now up to 2.1°C.



.... (1300Z): deepening Cu produced shower rain/snow mixed & snow
pellets from 1225Z, then the cloud transformed to layer type (though
no doubt Cu there / can't see it), and we've got light snow flakes
now - no impact surface/minimal impact visibility. OAT =
+2.0°C/DP=-0.4°C
