UK Outlook for Sunday 25 Aug 2019 to Tuesday 3 Sep 2019
Sunday is expected to be dry, bright and warm across most of the UK. Temperatures will be well above average across the southeast, but remain closer to normal in the northwest. The odd shower is possible but most people won't see one. On Monday (the Bank Holiday except in Scotland), warm dry weather is expected again in the south and east, but it may be wetter and windier in the far northwest. In the following days, dry warm weather may well continue in the south and east, though there is a risk of some thundery showers moving up from the near continent. Northern parts of the UK may see further spells of wet and windy weather, though some drier warmer spells are likely here too.
UK Outlook for Wednesday 4 Sep 2019 to Wednesday 18 Sep 2019
Confidence remains rather low during this period. Southern areas are most likely to see the driest and sunniest weather in the early days of September, perhaps with some lingering wet and windy conditions affecting the north. However, longer spells of dry and sunny weather may occasionally develop across all parts. Temperatures are generally likely to be warmer than average, although there is little indication of anything exceptional at this time.
Based on the latest output from various weather models, expert opinion and analysis by the Met Office, the long weather forecast provides guidance on expected weather conditions across the British Isles for the next 30 days.
The forecast provides useful information on the possible conditions. However, science, as yet, does not allow specific detail on, for example, the number of nights of frost, days of rain or snow. Nor will it highlight when specifically within the period any severe weather may occur.
Ensembles forecasts shown are from the latest run of the GFS computer model for Chelmsford. Apart from showing confidence levels in the short and medium range, it gives a guide of expected temperatures (minimum and maximum) and rainfall over the next two weeks.
