Temperatures to Climb This Weekend
The UK is set to experience a warm weekend, with temperatures reaching summer-like levels in some regions. It will feel warm and muggy, especially where sunny spells occur, but heavy rain is also anticipated.
Computer Models Differ on Long-Range Forecast
While computer weather models suggest a mixed picture for late September, there are currently no definitive signs of a heatwave. While some areas may experience warm spells, cooler conditions are expected to return by midweek.
Weekend Weather Outlook:
-
Saturday: Rain spreading southwards, clearing from Scotland and Northern Ireland but persisting into the afternoon across parts of northern England, Wales, and the Midlands. Possible heavy rain, thunder, and lightning.
-
Southern England: Largely dry with sunny intervals, feeling particularly warm and humid, with temperatures in the mid-20s Celsius.
-
Sunday: Rain lingering in southern England but clearing to a dry afternoon across much of the UK. Sunny spells and light winds. Temperatures slightly cooler in the northern half, rising further south. Parts of Wales, the Midlands, and southern England could reach 23-25°C.
Heatwave Criteria:
Temperatures would need to exceed:
- 25°C in Scotland and Northern Ireland.
- 28°C in the London area for three consecutive days to qualify as a heatwave.
Long-Range Prospects:
Computer models suggest unsettled weather for the next week or so, with areas of low pressure bringing rain and windy conditions. Later in September, high pressure could bring longer dry spells and above-average daytime temperatures. However, long-range forecasting is uncertain, and details may change.
There is currently no indication of a heatwave, but as autumn advances, cooler mornings could be on the horizon.
