UK long range weather forecast summary
The overall theme during most of this period will be mixed conditions. High pressure looks set to develop to the north of the UK, becoming a blocking feature and forcing our weather to come largely from the east. Drier days will be replaced by wet or showery days and this occurrence will happen quite regularly although some areas may get lucky escaping the worst of the rain, perhaps most likely across the north of the country. Heavy showers or longer spells of rain are more likely across the southern half of the UK and some of these showers will be thundery at times. Temperatures overall will likely be around average to slightly above but early in the period temperatures will be cool along eastern areas.
UK Long Range Weather Forecast WEEK 1 (20th May to 26th May):
Summary: Mixed conditions with average temperatures.
Quite a mixed period is expected with drier and brighter days interspersed with wetter or showery days. The flow in general will perhaps come from the north or north east as high pressure builds to the north of the country and this may mean western areas see more brightness than eastern areas as here, cloud cover will tend to be more frequent, with perhaps some light rain at times.
Later in the period heavy showers could develop across the south and some of these may be heavy at times. Overall however precipitation values will remain slightly below average, especially across the north. Temperatures will be no better than the seasonal average, with cool conditions possible in the east at times.
UK Long Range Weather Forecast WEEK 2 (27th May to 2nd June):
Summary: Signal persists for mixed conditions but feeling warmer.
Signals persist for mixed conditions as neither pressure will dominate. High pressure along with low pressure will come and go across the country during this period and as a result drier brighter days will be replaced by wetter and showery days. The blocking heights to the north of the UK is chiefly responsible for this pattern, with the flow generally coming from the east or even south-east at times. As a result conditions will feel a touch warmer but again showers may be heavy across the south. Temperatures overall will remain slightly above the seasonal average with rainfall amounts around average, perhaps below across the northern half of the UK.
UK Long Range Weather Forecast WEEK 3 (3rd June to 9th June):
Summary: Little change likely as blocking continues.
Confidence becomes much lower during this period but signals hint at mixed conditions continuing with higher heights still to the north of the UK, meaning the flow remains generally from the east. Again there will be plenty of fine sunny periods but also rain and showers at times and again these are more likely across the south of the UK with northern areas perhaps seeing the brightest conditions. Temperatures will remain slightly above normal with rainfall around average for the south, below average across the north.
UK Long Range Weather Forecast WEEK 4 (10th June to 16th June):
Summary: No signal for either pressure to dominate, remaining mixed.
Long range models are largely against each other for this period with none in full agreement but taking the overall view, it’s possible that mixed conditions will prevail. There is no clear signal for any drier weather but equally no firm signal for wet weather either so expect a mixture of drier days and wetter or showery days. Temperatures and rainfall are likely to come in around the seasonal average.
