Stratus not quite melting away as quickly as planned…

Southeast sizzle on another hot Fri-day
Temperatures peaked at 36.4°C in the mid afternoon at London Heathrow Airport and Kew Gardens according to the Met Office Twitter feed – yippee! I shouldn’t be surprised if the Met Office don’t have a climate …

The large cumulonimbus that has rapidly developed in the last three hour and is now close to Paris at 1245 UTC is tracking N’NE and will miss Kent by a long chalk. But there are signs …
Northern Scotland on edge of rain band
Yesterday’s NWP models were spot on about how far today’s rain would extend northward. Much of the northern Highlands have stayed clear of the rain from low Beate. We just had a couple of hours here …

High speed stratus

Low Juliane from above
A very dramatic view of low Juliane from above this afternoon with some big CBs across eastern England and some lovely multi-cellular cloud streaming down from the northwest close to Ireland. I would like to have …

It is rather uncommon to see a spell of moderate rain with pressure over 1030 hPa but it’s forecast to happen overnight across northern Scotland. There seems to be no end to these kind of scenarios …

Low Gudrun
So the UKMO finally issue a yellow warning for strong wind for Friday, but they reckon that gusts of 50 to 60 mph will only affect Northern Ireland and nowhere else? Obviously they know more than …

It’s been a long time since I’ve seen it snow in May, but as I write the snow is swirling down again from another shower in Strathpeffer (40 metres AMSL). The air temperature before the shower …
Sparkling day
It’s a sparkling day across most of the country with blue skies and strong spring sunshine, except that is for the northern Isles and western Cornwall.
Rain in the south another frost for Scotland
Another beautiful clear and sunny, if not cold start to the day in the Highlands, we certainly need a good day to make up for the non-stop April showers of yesterday, but the air frosts just …
