UK Outlook for Friday 25 Jan 2019 to Sunday 3 Feb 2019

On Friday, southeastern areas are likely to stay dry, bright and cold, perhaps with some freezing fog patches at first. Elsewhere it could turn less cold as a band of rain and drizzle moves in from the west, with some hill snow possible in the north. However, there is a small chance that it could stay dry, bright and cold across much of the country with wintry showers in the east. Thereafter, an unsettled period of weather is possible with further band of rain moving southeast across the UK, with brighter and showery weather in between. Snow is also possible in some northern and central areas at times as it turns increasingly cold with overnight frosts, although some brief milder interludes are possible too.

UK Outlook for Monday 4 Feb 2019 to Monday 18 Feb 2019

Changeable conditions are most likely at first, with spells of rain, strong winds and some snow at times. However, very cold conditions are more likely to develop through this period with a greater chance of northerly and easterly winds. This brings an enhanced risk of snow and widespread frosts, however there is currently a large amount of uncertainty. The driest and brightest weather is likely to be in the northwest. The conditions described above could still be interspersed by some milder and wetter interludes, most likely across southern parts of the British Isles, and this would bring a risk of significant snow and ice at times.

Forecast Information

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.
