UK Braces for Extended Dry Spell as High Pressure Dominates
Met Office issues fog warning for Friday morning while long-term forecast indicates a prolonged period of dry weather, raising drought concerns.
Hazardous driving conditions are expected across parts of the UK on Friday morning due to thick fog, prompting a yellow severe weather warning from the Met Office. The warning covers areas including Lincolnshire, the East Midlands, the Home Counties, and parts of Greater London, with visibility potentially dropping below 100 metres during the morning rush hour. The fog is forecast to gradually lift and clear throughout the day, though some rural areas in eastern England may experience lingering fog until the afternoon.
Looking ahead to the weekend, early morning mist and fog patches on Saturday may give way to low cloud, potentially persisting throughout the day in some regions. Despite this, many areas are expected to remain dry with intermittent sunshine. The exception is northwest Scotland, where a weather front is predicted to bring cloudier skies and rain. Temperatures are anticipated to remain close to average.
By Sunday, the fading weather front may introduce some thicker cloud to Wales and central England, with a possibility of light rain or drizzle. The rest of the UK is expected to experience a dry day with variable cloud cover and some sunshine.
Extended Dry Period Ahead
The UK is set to enter an extended period of predominantly dry weather as high pressure builds and is expected to dominate for at least ten days. This pattern is a significant shift from the recent stormy conditions, which were fueled by a powerful Atlantic jet stream. The current high-pressure system is attributed to a 'diffluent blocking pattern' in the Atlantic jet stream, which will impede weather systems from reaching the UK.
This prolonged dry spell is likely to exacerbate existing drought conditions. According to the Environment Agency, 82% of England remains in drought status. While recent rainfall provided some short-term hydrological benefit, sustained precipitation is needed for rivers, reservoirs, and groundwater levels to recover fully. Philip Duffy, Chief Executive of the Environment Agency, emphasized that "A few wet days cannot reverse months of hot, dry weather." Water companies are being urged to accelerate leak repairs, and the public is encouraged to conserve water.
The Met Office's three-month outlook suggests a doubled chance of wetter-than-average conditions due to El Niño, but the immediate forecast points towards a sustained dry period. Any precipitation during this time is expected to be minimal, likely associated with early morning mist and fog.
With no storms currently on the horizon, the next named storm, Chloe, is not expected in the immediate future. The extended lack of rainfall is a significant concern for drought management and the recovery of water resources across England.
