UK Weather - Summer 2024

Unread post by Simon Culling »

Summer has started with high pressure resident to our west (1036mb at 12Z today - 2nd June - well to the west of Eire - see chart below) and a slack N-NW flow that is warming as daily sunshine radiation is now above night-time radiational cooling. It has been nice and warm over much of central and western parts of the UK, but a breeze just off the North Sea is still keeping eastern parts cooler - this is normal in Spring and into early Summer. The temperature reached 23-24°C over much of England + Wales (away from the coast) today (Sun 2nd June) and here in Tiverton we had a sunny and warm day with a light wind and a high of 22°C - best day of the year so far as the humidity was quite low so it felt very comfortable.

However, the high will retreat a little further west this coming week allowing low pressures to move SE across Scandinavia and we will see a renewal of the NW flow with rain and/or showers and much cooler conditions. But here in the SW rainfall totals should be small.

Whilst it has remained mostly dry here in the south, there have been plenty of showers in the last few days in the northern half of the UK where it has been on the chilly side. As the high pressure retreated a little to the west (into mid-Atlantic), lows have been able to move SE from Iceland and we are stuck in a cool NW flow. Down here in the SW it has been dry with variable amounts of cloud and some sunshine at times - just a few fleeting very light showers today. The nights have been chilly with the temperature falling to 5°C on a couple of nights here in Tiverton town, but out in the country there has been a nip of ground frost in more sheltered locations. Not unusual for early June, but rather a contrast to the very warm start we have seen to the year so far.

A small waterspout was observed this morning off the west Wales coast (near to Borth) and it appears to have come ashore and inconvenienced some campers. Thankfully, only minor damage. Picture copied from this linked tweet.

The CET for June was 12.9°C (-1.2°C) up to the 6th and the EWR was 3mm up to the 5th which is just 4% of the monthly average of 71mm.

The rather chilly theme to the weather this June has continued as we still have winds from a northerly quarter. There has not been much in the way of rain with showers rather than continuous precipitation - and this looks like continuing through the coming weekend and into early next week. After that the models indicate a considerable warm up, but with the unsettled theme continuing with winds more from the S-SW.

This morning (Thursday 13th June) there was an air frost in places in Scotland and the low of -1.6°C at Kinbrace Hatchery in the far north (County of Sutherland) was a new date record minimum for the 13th - beating the old record of -1.4°C set at Dalwhinne (Highlands) in 1978. It is not often nowadays that we see any minimum records being set.

The last few days have been showery, but the temperatures have begun to creep up - daytime maximums are now getting to around 20°C for England + Wales which is near to average. The showers have been heavy and thundery and there were 8 reported funnel clouds on Saturday (15th June) and a couple more yesterday (Tues 18th) - this is quite normal on showery days in late Spring and into the Summer, especially when local convergence zones become established. Picture below is from a video of a long funnel near to Burnley in Lancashire yesterday.

The forecasts for the next 10 days are rather promising with high pressure becoming dominant with plenty of dry and warm weather on the cards - not sure on the sunshine front as we can be plagued by cumulus development in the UK which spreads out in the afternoon to a Sc sheet to hide the sun.

The CET for June was 12.1°C (-2.0°C) up to the 14th and the EWR was 21mm also up to the 14th, which is 30% of the monthly average. The temperature average may return to a small surplus by the end of the month if the current long range forecast proves correct.
