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...
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...
This is getting rather monotonous. It’s reached 18°C again across many parts of northwest England again today under glorious blue skies. Meanwhile 250 miles further north we’re basking in occasional rain and 8°C, but the strong winds of the last few days have now abated. I notice that...
It’s not uncommon to see very mild temperatures in March so this afternoon values widely above 16°C and locally up to 19°C, with a little help from Snowdonia, shouldn’t be considered another sign of global warming as so often they are. Temperatures as high as 25.6°C have been...
Not unsurprisingly the north of Scotland saw up to 30 nights with air frost in what has been a very mild Winter. There are a dozen or so coastal sites around the IONA that got away with a frost free winter including places such as Fair Isle in...
The high pressure has brought some low negative dew point and resultant low humidity air across central England today. There is an area of descent and relative humidities down to around 30% close to Birmingham which although not remarkably low humidities will help dry you dry washing and...
I meant to post these graphics of the diurnal range in temperature across IONA between yesterday’s maximum [06-18] and the overnight minimum [18-06]. It was obviously going to be large on a spring morning after such a near perfect night of radiative cooling across Scotland, and Aboyne didn’t...
The vernal equinox occurred precisely at 0349 UTC this morning and to help celebrate the fact it’s been another sunny start with Mediterranean blue skies across many northern parts of the country. Pressure has continued to build strongly overnight and the barometer has now topped 1037 hPa across...
At last a dry and sunny morning here in the northeast of Scotland for change, but that’s not likely to last for very long.
The freely available gridded data series for temperature by the Met Office has now been extended back to 1884, so I thought I would take a closer look at it by means of 12 month moving averages of maximum, mean and minimum temperature, by adding a couple of...
There was a moderate to severe frost over the north of Scotland last night, call me pedantic if you like, but I think that’s a more accurate way of describing what a beautiful frosty morning it is than “some of us started off with a bit of frost”....
There seems to be no respite in the exceptional warmth that we have seen across much of Europe, Scandinavia and western Russia this winter. Mean temperature anomalies for the first thirteen days of March are close to +10°C across the Ukraine, it’s no wonder that the SST’s in...
It’s a very mild afternoon across much of England, that’s thanks to the disintegrating remains of a warm sector that most of the area is still sat in. Temperature anomalies at 12 UTC were widely between 5 and 7°C above the long-term average, and at Weybourne in North...
I am bit late on this one, and it won’t come as a big surprise for people further south but spring has sprung, well at least in central England. It happened on the 17th of February and that’s a full 33 days earlier than it normally does on...
It was a mild early March day everywhere eventually yesterday, with temperatures widely up to 12 or 13°C across the whole of IONA (well except the Faroes which I suppose must also be a part of IONA). The warmth took it’s time to permeate through to the northeast...
I normally watch the weather spot at 2.30 PM each day on the BBC News channel on most days, it’s a real education, but why has it taken the BBC weathercasters so long to cotton on to the fact that it’s been so very mild across Europe, particularly...
