Storm Forecast Issued: 2009-06-17 16:00:00
Valid: 2009-06-18 00:00:00 - 2009-06-18 23:59:00
Regions Affected
Northwest, West & Southwest Scotland, Northern Ireland and parts of Ireland ( all of Scotland & Ireland, and parts of Northern England and Northwest Wales are included in the WATCH )
Synopsis
An unstable and cool airflow affects the UK during Thursday as a cold front exits into the nearby continent. The Azores High extends into southern areas of the UK, whilst an area of Low pressure centred between the Faroe Islands and Iceland dominates the weather across northern UK. Numerous showers are expected to affect much of Scotland & Northern Ireland and northern and western parts of Ireland & Northern England during the day. Some of the showers are expected to be heavy with hail likely, and also occasional thunder and lightning, especially where the showers are most frequent (in the areas highlighted on the map). Strong winds, gusting to Gale force at times, will ensure any showers move quickly, and therefore the risk flash flooding seems minimal. However the showers will be very frequent across western upslopes in particular. The showers will move further south during the evening and overnight, possibly affecting parts of north and west Wales, whilst also advancing southwards down the North Sea. Showers should become increasingly confined to the coasts overnight.
