TORRO CONVECTIVE DISCUSSION 2010/016
A TORRO CONVECTIVE DISCUSSION has been issued at 12:25GMT on Tuesday 7th September 2010
Valid from/until: 12:25-2000GMT on Tuesday 7th September 2010 for the following regions of the United Kingdom & Eire:
Much of England
Wales
Eastern Eire
Much of N Ireland
S & Cent Scotland
THREATS
Hail 10-15mm diameter; wind gusts to 45-50mph; CG lightning; isolated tornadoes
SYNOPSIS
Upper trough will approach from the west with an unstable, moist airmass in place across much of the area, behind a northward moving occluded front, which is currently across central Scotland. Showers and thunderstorms have developed within the unstable airmass, due to diurnal heating and the approach of the trough. Shear is sufficient for organised multicells capable of marginally severe wind and hail. Low-level shear is not too high, but the combination of low LCLs and marginal shear means isolated tornadoes are possible, especially across the northern portions of the area.
Forecaster: RPK
