Hot Spell to Break as Thunderstorms and Heavy Rain Sweep In

The current hot weather is set to break from Sunday afternoon, ushering in a spell of unsettled conditions lasting through next week.

Heavy and scattered thunderstorms, along with longer spells of rain, will bring above-average rainfall nationwide. Western counties could see totals of up to 70mm by week’s end, while the far south and southeast may see lower amounts between 20–30mm.

Saturday will remain hot and sunny, with temperatures widely in the mid to high 20s and potentially exceeding 30°C in some areas.

Very warm conditions will linger into Sunday, but cooler air will begin pushing in from the southwest by afternoon, extending eastward through the evening. Thunderstorms are likely to develop in the west from mid-afternoon, with risks of localised flooding and power outages.

The unsettled pattern continues into next week, with scattered showers and longer spells of rain—some of it thundery—expected each day.

Temperatures on Monday and Tuesday will dip to the mid to high teens before gradually rising again later in the week to the high teens or mid-20s. High humidity may trigger further thunderstorms later in the week.

This showery, Atlantic-driven pattern is expected to persist into next weekend and beyond.
