Valid: 2009-05-21 00:00:00 - 2009-05-21 23:59:00
Regions Affected
Northern Ireland, East Midlands, Yorkshire, counties bordering The Wash and Northern, Eastern & Southern Scotland (all of the UK, excluding the south coast, is included in the WATCH region)
Synopsis
Showers are expected to develop widely across Northern Ireland, Scotland, and central & northern England during Thursday, in response to daytime heating. Thunderstorms are also likely to develop - the most favoured region based on current data is northeast Scotland, where storms may cluster during the afternoon and evening hours. Thunderstorms are also forecast across parts of Northern Ireland, eastern parts of Ireland and also perhaps eastern parts of England. Surface based storms may develop, which may produce a funnel or weak tornado. Hail and gusty winds are likely to accompany many of the showers, and torrential downpours combined with light winds may result with local flooding due to the persistence of the showers. Showers and storms are forecast to rapidly decrease in coverage during the evening, although they may persist for some time across eastern Scotland in particular during the evening.
