With low pressure approaching from the SW and high pressure building over the continent it means we’ve increasingly humid air drifting in from the Atlantic merging with very warm air lifting from the continent. So, despite a cloudy day for most, it’ll feel increasingly warm and humid into this evening.

Setup today through Thursday.

A lot of cloud over the UK but a little brighter over Ireland means a little warmer here. It reached at least 24C in the Dublin area, 23C Tyrone this afternoon.

Thanks to the juicy air and thickening cloud after sunset, today’s warmth is trapped. We could see some record high September minimum temperatures tonight!

A more southerly air flow Tuesday/Tuesday means less moisture and therefore a greater chance of seeing more sunshine Tue/Wed and therefore warmer temps.

However, the high only holds back the inevitable for so long and we have change by late week.

The trough is soon to return according to the CFSv2 weeklies and we should begin to feel a little more autumn-like.

See today’s video.
