... (11/0915Z): steady, light snow - but I can now see the As tr above
St fra so I suspect it's on the way out. VIS back up to ~4 km; shallow,
non-continuous cover on roofs, sheds and similar: all blacktop surfaces
wet with only a light/patchy cover at the edges of sheltered pathways.
Quite difficult to assess (for 09Z reading) whether we've got a genuine
more-than-halfcover of snow - I'd assess as 60% given our suburban
character, so only just. Depth just about 1 cm on shed roof and screen,
otherwise 0.5 cm and much of it just about 0.1 cm.

OAT = -0.6°C // DP -2.8°C.


.... (11/1155Z): still light PPN, small flakes of snow, wandering lazily
down out of thin As (sun's position clearly seen); low-level air clearly
drying out as the previous St fra has dispersed as far as I can see. No
impact from PPN, VIS good now, at least 12 km, and earlier snow cover,
such as it was, has largely melted off from residual/stored heat.

OAT = +1.1°C // DP = -3.9°C.

Martin.
