Looking unsettled late June

Duty forecaster: Garry Nicholson

Risk of thunderstorms midweek

The current hot spell will transition into a thundery breakdown in midweek as humidity builds and fronts spread in from the Atlantic. Much fresher conditions will arrive by the end of the week, leading to a rather changeable outlook for the rest of June, although the far south may see further very warm days into next week.
