Valid: 2009-05-17 23:00:00 - 2009-05-18 22:59:00
Regions Affected
Scotland, Northern Ireland, Northwest & Northeast England (all of the UK is included in the WATCH)
Synopsis
An unstable airmass continues to affect much of the UK during Monday. Showers will affect many western coasts from the very beginning of this forecast period, but they are forecast to become increasingly heavy, frequent and widespread, particularly in northern UK during Monday. Thunderstorms are also likely to develop in response to daytime heating, especially across Scotland, Northern Ireland, Ireland and Northern England. The showers will be heavy in most places, but across England and Wales strong and gusty winds will ensure that the showers only last a short period, whilst across Scotland and Northern Ireland lighter winds could give rise to local flooding due to persistent torrential downpours in places. Hail and gusty winds are likely to accompany many showers. The showers should rapidly decrease in coverage around or soon after sunset.
