Steepening mid-level lapse rates and diurnal heating will allow a few scattered heavy showers to develop over parts of Scotland, Northern Ireland and northwest Republic of Ireland Tuesday afternoon. Instability is not particularly impressive, though strong DLS may compensate to produce a few isolated lightning strikes. Forecast profiles look quite dry in the upper troposphere, and deep convection may become capped around 500mb.


Later in the night a much more significant upper cold pool arrives from the Atlantic, accompanied by numerous showers into western coasts of Ireland and Scotland. Again some isolated lightning will be possible from this activity, given very steep mid-level lapse rates and some marginal instability.
