March 2020 – wet in the northwest but rather dry in the east

March 2020 was a wet month in the northwest of Scotland, but further south and east rainfall was closer to the seasonal average, and the further east that you came the drier it became, such that counties bordering the North Sea, such as East Yorkshire, Lincolnshire and Norfolk...

Rise in global temperature checked in March

The rise in the 12 month moving average in global temperatures has been checked during March in my DIY series after rising continually since August 2018. My DIY global temperature series has been wrong before, and it may well be wrong about this, but as far as I...

Today’s visible satellite image

Just fascinating to watch the movement in the multicellular cloud to the west of IONA. If you watch closely there seems to be a pulse of could moving westward as the day progresses, I reckon it must be another thin layer of altocumulus or more likely a thin...

A shock to the system

The temperatures over the weekend must have come as quite a shock to the system to people who are hunkered down self isolating across England and Wales, especially those in the northwest, where maximum temperatures on Sunday were as much as 12°C lower than they were on Wednesday.

MOSAiC expedition flushed out of Arctic

It seems to me that although the MOSAiC expedition may end up being a huge success as far as a collaborative scientific mission goes, it missed the most important aspect (to me at least) of reaching and crossing the North Pole, and now the Polar Stern seems to...

A quick dip in Arctic sea ice

The better start to the Arctic sea ice extent season didn’t last too long because of a week or so of large daily losses during the second half of March, which look like they seem to have stopped for now. Otherwise sea ice extents are the 8th lowest...

As the days grow longer the cold gets stronger…

I think the 12 UTC anomaly chart is much more informative than the 12 UTC wind chill chart. There were negative wind chill values down the east coast and on any high ground. I notice as the axis of the ridge from the intense anticyclone Keywan slipped south...

New March record of 1051.3 hPa at Malin Head

I guessed correctly because as far as I can see Malin Head pipped Tiree to the highest March MSLP in March. At 11 UTC this morning the pressure there was 1051.3 hPa or 31.04″ of mercury. This is the fourth highest pressure ever recorded across the British Isles...

08 UTC wind chill

The wind chill is negative across many parts of the country this morning.

March highest pressure record broken

This one caught me out. I had committed the cardinal sin of believing that NWP is always right, something that you can usually take for granted, but not always. The 1049.3 hPa at Stornoway at 21 UTC is the highest pressure in the British Isles for March. It...

Todays anomalies & windchill

The BBC weathercasters are already making a play about how high the windchill factor will be across England and Wales on Sunday, so I thought I’d just make a point in saying that there’s also a strong wind chill across Scotland today. But of course that’s not very...

Lock down week 1

It’s been quite a week one way or another, what with the Corona Virus lock down and then most of England and Wales seeing seven straight sunny days. It’s been no wonder people have been tempted to go out and try and get some of that spring sunshine,...

Showers in north as air mass cools

After finally seeing the back of that old cold front I never expected to see showers following on so quickly behind during this afternoon.

So much for that much anticipated meridional spell

I must have put the kiss of death on it when I wrote about how this huge high pressure (with a central pressure of 1054 hPa by this Sunday) was looking like it would stick around for at least the next ten days, only to find that the...

Sunshine totals since Saturday

Six sunny days with between ten and twelve hours of sunshine each day across many parts of England and Wales, with another sunny day to come, which is highly likely to be the last. Weybourne in Norfolk is top of the IONA sunshine table for the last six...

Much of a muchness

I see Scotia Myopia is still alive and kicking down in Exeter. As far as I know you are allowed to use 280 characters in a Tweet these days – so why leave out the northwest Highlands and Islands? I wouldn’t mind so much if the statement they...
