The Met Office eventually did modify their yellow wind warning for strong wind which they originally had issued on Friday morning, but it took them till 0827 BST this morning to do it! That meant the …
Wendy not that windy as Met Office modify their warning Read More »
The various models have got their knickers in a twist about how low Wendy will develop overnight as it runs eastward across Scotland. The latest consensus from four of the worlds NWP models is that it …
The values of the maximum rainfall accumulations in their amended and shortened yellow warning for heavy rain look fairly reasonable, maybe totals were a little higher over the highest ground across Argyl, but they forgot to …
The latest NWP forecasts do show a strong potential for a spell of severe gales across the northern Scotland on Sunday morning. Let’s see if the UKMO sit this one out as they so often do …
The old occlusion (in all reality a cold front) that has been edging south for the last 36 hours or so has refused to die gracefully, and has deposited as much as 40 to 50 mm …
Results from my rainfall estimates from weather radar were a bit mixed over the last 30 hours. My estimate for Capel Curig was too high whilst the estimate for Keswick was on the low side. That’s …
I notice that the yellow warning for heavy rain has been updated by the Met Office to cover the north and west of Scotland. Wise move, as it’s already been bucketing down here in the strath …
It is not very often that we get three thundery days in a row across IONA, so this one is a little exceptional in that regard, and who knows it might extend to four or five …
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 …
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 …
Highest rainfall accumulations in the Lochaber region of Scotland for the last 40 hours or so (since 18 UTC on the 21st of May) indicate that there has been between 175 and 200 mm of rainfall …
The winds are quite lively over parts of England and Wales this afternoon. I wonder if the UKMO are now regretting not taking low Gudrun a little bit more seriously and extending their yellow warning area …
I can’t understand why the UKMO were so reluctant to issue a yellow warning for strong winds for later this afternoon for western Scotland. The NWP models have all been very consistent about how 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 …
The Met Office are playing it cool about issuing a warning for the forecast strong winds associated with low Gudrun later this week. Met Eireann wisely on the other hand have already issued a yellow warning …
Nothing particularly unusual about Friday’s low for May. The ECMWF hires model has it’s minimum central pressure at around 970 hPa at midnight on Friday. They forecast the low itself will skirt wide of the northwest …
I am not sure that the yellow warning for strong winds for the southwest overnight was totally necessary. Winds this strength affecting north of the border would attract little attention from Exeter. With regard to this …
Yesterday’s hurriedly issued yellow warning for thunderstorms and heavy rain by the Met Office was very accurate as far as maximum rainfall totals were concerned, but the area of the warning didn’t extend far enough southeast …
12 April 2020 – Hit and miss thunderstorm warning Read More »
The Met Office seem to have missed the SFERICs that have broken out across the west of London in their yellow warning for thunderstorms this afternoon for the north Midlands. This looks like medium level instability …

This is a chart of estimated rainfall totals since 12 UTC on Monday that’s a period of almost 26 hours, the estimates look fairly reasonable when compared to the reported totals from the SYNOPs. The highest …
The models are predicting a wet start to the week across western Scotland, particularly on the Outer isles and Skye. The totals don’t look quite as dire in the 00 UTC run of the GFS as …
There are no warnings of strong wind in force today from the Met Office. But Meteoalarm reveals that’s not the case in other countries across Europe. Portugal have warnings issued for gusts of 75 kph on …
The only reason that I can see why almost identical warnings were issued for heavy rain across central Wales and central northern England, one amber and the other yellow, is that the Met Office thought that …
