Storm Forecast Issued: 2010-10-22 20:28:00
Valid: 2010-10-23 00:00:00 - 2010-10-23 23:59:00

Regions Affected
Wales, Midlands, East Anglia, SE, CS + SW England and Ireland (all of the United Kingdom is included in the WATCH)

Synopsis

Low pressure "Ursula" (FU Berlin) centred over the North Sea will dominate the weather across the country on Saturday.

Behind an eastward-moving cold front, clearing the east by late morning, a cold rPm airmass is advected across the majority of the country, steepening lapse rates. Scattered showers and isolated thunderstorms are forecast to affect many parts of the country, particularly nearer the coasts.

Given the airmass, hail is likely in many of the showers, perhaps locally large in diameter, particularly (but not exclusively) in southern counties of England. There exists the potential for a spout to form. Gusty, blustery winds will accompany heavier showers.

Showers are forecast to decrease in coverage rapidly during the evening hours, becoming increasingly confined to the coasts.
