Day 2 Convective Outlook
VALID 06:00 UTC Tue 28 Mar 2017 - 05:59 UTC Wed 29 Mar 2017

ISSUED 18:09 UTC Mon 27 Mar 2017


A shortwave trough will migrate NE from Biscay and across the British Isles on Tuesday, accompanied by cool mid-levels and hence steeper lapse rates. Assuming this phases favourably with diurnal heating, several hundred Jkg-1 CAPE will allow scattered showers and a few thunderstorms to develop. However, there is a chance that the upper trough may move through slightly too early for peak heating.

Nonetheless, a SLGT has been introduced where there is some reasonable confidence for an overlap of instability and upper-level support for at least a few scattered thunderstorms to develop, especially during the afternoon/early evening. It is plausible another SLGT may be needed for portions of E Wales and the Midlands into southern parts of N England, but forecast profiles look drier farther east with hints of capping - so while a few showers and/or thunderstorms are also possible here, they are likely to be more isolated / well-scattered in nature, and hence coverage perhaps not high enough to upgrade to SLGT at this stage.

Given instability and dry air aloft, hail up to 1.5cm in diameter is possible in the strongest cells.

The skies were pure black when I left Fairymount so that's not a surprise!

Any upgrade IYO for today/tomorrow Meteorite58?

06z shows a risk for the NW this evening. Initiating over land then quickly moving out over water. Could still put on a light show for people near the coast.

Decent shear for storms to organise. Could be some nice hail in places before it moves over water.

One worry though would be the cloud moving up from the south which may limit initiation. http://en.sat24.com/HD/en/eu/visual
