Storm Forecast Issued: 2010-09-07 00:48:00
Valid: 2010-09-07 00:00:00 - 2010-09-07 23:59:00
Regions Affected
Wales, Northern Ireland, S Scotland and England (excluding East Anglia and SE England - all parts of the UK south of the Moray Firth are included in the WATCH)
Synopsis
Behind a cold front moving erratically northwards across northern Britain, an rPm airmass is advected across Ireland, England and Wales. Steep lapse rates are expected to enable widespread showers and thunderstorms to develop over a good portion of the country, including overseas, given enough insolation and cloud clearance from the straddling front.
In any of the showers, given the airmass, hail seems very likely, perhaps up to 3cm in diameter. Thunder and lightning is expected to be quite widespread, but rather more isolated in the east due to less favourable cloud heights.
Showers should become to confined to coastal parts, and over the north Atlantic, during the evening and night hours, though brisk winds may enable them to travel further inland. The risk of thunder/lightning continues into the night.
