... (11/0715Z): light, small flakes of snow - VIS ~4km - now covering
most roof surfaces and patchy covering on paths, but roads clear and
running well. At 06Z (first light), even less impact with just a few
patches on roofs, all blacktop surfaces clear. Even struggling to settle
on grass. No impact on daily life if this is the worst it gets.
OAT = -0.2°C.


... (11/0800Z): steady/slight - but recently could just about justify
something a little more intense? VIS now come down noticeably - circa
1500M, with a 'misty' element. More surfaces picking up a shallow cover
- but roads/paving etc., all fine/clear.
OAT = -0.4°C


.... (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.
