Storm Forecast Issued: 2010-07-11 23:21:00
Valid: 2010-07-12 00:00:00 - 2010-07-12 23:59:00
Regions Affected
(SE England, East Anglia and Northern Ireland are included in the WATCH)
Synopsis
Low pressure "Mae" moving northeastwards away from the United Kingdom, west of Scandinavia, and Low pressure "Norina" approaching the southwest of the country will dominate the weather on Monday.
There is a low risk of convective activity associated with a developing wave along the cold front as cyclogenesis occurs over the southeast of England and nearby continent during the early hours in association with the destabilisation of the warm and humid airmass present there. The risk of thunder/lightning decreases significantly by dawn, but pulses of heavy rain may give localised flooding given the dry, baked nature of the ground.
Attention then turns to Northern Ireland and Ireland where scattered showers are forecast to develop as the winds fall slack. There is a low risk of thunder and/or lightning, with cloud heights limiting this chance, thus any lightning is likely to be quite isolated.
