Aside from the risk of severe weather as a result of rain, sleet, snow and freezing rain across England, Wales and Scotland, there may be a window of opportunity for some well-forced convection to occur over the Republic of Ireland on Saturday afternoon, either along or just ahead of the wrap-around occlusion. Strong low-level shear and a marked wind veer suggests the potential for perhaps a tornado. Some sporadic lightning and hail will be possible - reluctant to issue a SLGT since the risk of lightning is considered below the 30% threshold, but have issued a low-end SLGT to better highlight the areas at risk.

Elsewhere, showers will become more widespread over the Celtic Sea and English Channel (and adjacent land areas) on Saturday night as cold air aloft overspreads relatively warm SSTs. A few sporadic lightning strikes, small hail and gusty winds will be possible from the most intense cells.
