Second amber warning of thunderstorms
A second amber warning has been issued by the Met Office for thunderstorms this afternoon, this one for western areas of England and Wales, but unlike last nights amber warning which they got out in good …
Where’s nowcasting when you need it most?
You may not have heard much about nowcasting. It’s a short-range forecasting technique pioneered by the UKMO. It strikes me (no pun intended) that it would be a handy thing to have on a day like …
Heatwave goes out with a bang as Met Office issue thunderstorm warnings for the next five days in the south
One of Jimmy Greaves favourite expression was that football was “a funny old game” and I’m sure the same expression could be equally applied to describe the weather so far in August 2020. The Met Office …
Four inches of rain across Fife overnight
My estimates from weather radar images suggest that there has been around four inches of rain from severe thunderstorms in a belt that stretches northward from Edinburgh, across the Firth of Forth then on into Fife …
Isolated thunderstorm tracks north across the Cairngorms
All quiet across the UK on the thunderstorm front apart from this single cell moving more or less due north across the southern Cairngorms.
Drat – missed it!
The UKMO mesoscale model seems to be floundering with these thunderstorms at the moment, it’s no wonder the Met Office have had to issue blanket yellow thunderstorm warnings for the entire UK for the next three …
Heat low triggers thunderstorm close to Coventry
It has been awhile since I’ve seen a proper heat low form over the UK, but it has this afternoon just to the west of London, and this evening it has managed to spark of a …

Heatwaves and today’s thunderstorms
Tomasz Schafernaker has a theory that today’s thunderstorms are only occurring where there hasn’t been a heatwave so far, which just goes to show what he knows about the definition for heatwave definition, and the fact …
Uncertain about where and when thunderstorms will occur? Then why issue a warning!
A third update to the ongoing saga of the thunderstorms that are forecast for coming week. It seems that the UKMO have now narrowed the area down a bit, but are still uncertain about the location …

Met Office covering all their bases
The Met Office are certainly intent on covering all their bases with two separate (!) 24 hour yellow warnings for thunderstorms next Monday and Tuesday. I have no idea what merit they is in putting out …
A tale of three warnings
I have never seen a warning specifically issued for the Shetland Isles before, and that includes strong winds, but the Met Office in their wisdom decided to issue one specifically for them for just 20 to …
Thunderstorm close to Paris
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 …
This evenings thunderstorms
A terrific collection of cumulonimbus clouds scattered across the continent and edging N’NW into blighty at the moment.
Fifth day of thunderstorms
A fifth day of thunderstorms across central and southern parts of the UK, and if yesterday’s thunderstorms hadn’t dampened things down a touch, then another band of moderate or heavy overnight rain finished the job off. …
A fourth day of thunderstorms
A dreadful last few days north of Inverness. Rather humid and cloudy with fog and low cloud in the mornings gradually clearing to reveal another layer of upper low or medium cloud during the afternoon, with …
No flies on the Met Office
There are no flies on the Met Office this week. Quick as a flash they’ve latched on to the main theme of this week’s weather, there’ve been some thunderstorms around! And just to let us know …
Model misses thunderstorms again (update 3)
Whatever mesoscale model the UKMO are using to predict where and when thunderstorms are likely to break out looks like it requires some tweaking, because this is the second day it’s missed thunderstorms that have formed …
Thunderstorms show up late
I did wonder if yesterday evening’s thunderstorms that spread northwest across the heart of central England were ever going to materialise, but they finally make it across northwest England at around 19 UTC. It’s notoriously difficult …
Yesterdays rain and thunderstorms
Unfortunately we live close to the wettest place in the UK yesterday and I can testify to the fact that yesterday afternoon was pretty dire with outbreaks of heavy rain up here, and which continued into …
Thunderstorms breaking out over northern France
So far there has been little SFERIC activity in the rain that’s been falling across the south, that might well be set to change as thunderstorms are now breaking out behind the frontal zone across northern …
16 April 2020 – thundery showers
In this estimate of rainfall accumulations from weather radar, most of yesterday’s rainfall across the southeast at lunchtime, looks likely to have been falling from medium level unstable cloud and barely reached the ground. The thunderstorm …
Another one they missed
Quite a large thunderstorm and cumulonimbus cloud developed close to the coast of northern France at around 15 UTC this afternoon, you can see the anvil clearly in the 1645 UTC visible satellite image, along with …
Active cold front crosses Georgia
I noticed this active cold front that was crossing Georgia at 06 UTC this morning. Quite a common occurrence at this time of year in the United States when there is still an abundant supply of …
