Broad Blunsdon (Swindon) weather

Headline:

Increasingly warm this week.

This Evening and Tonight:

Plenty of late spells of sunshine for many with clear skies at first overnight. Turning increasingly misty in the west, with fog developing readily across higher ground. Dry for all, with light winds. Warmer than last night, feeling rather muggy. Minimum temperature 13 °C.

Thursday:

Early mist and fog will soon clear, leaving a widely dry and sunny day. Feeling warm for all with light winds and plenty of strong sunshine. Maximum temperature 29 °C.

Outlook for Friday to Sunday:

Remaining dry and settled beneath high pressure this weekend. Plenty of strong, hot sunshine by day and clear skies overnight, although staying humid and rather muggy. Breezier by Sunday.

The heatwave from the weekend will be gradually eroded from the west early next week as a cold front arrives from the Atlantic. This will bring the chance of some heavy rain or showers, perhaps thundery, especially in northern and western areas. Towards and beyond midweek, a rather changeable pattern is anticipated with some rain or showers possible at times, which could be heavy and thundery, and particularly focussed in western and northwestern areas. Longer drier spells are most likely towards the south and east, although even here some showers may be possible at times. Temperatures are likely to remain above average, especially in the south and east where further spells of very warm or hot weather remain possible.

A continuation of the broad themes from earlier in the month at first, with high pressure probably dominating the south and lower pressure more favoured to affect the north and northwest. Temperatures are likely to end up above average overall with a continued, and perhaps higher than normal, chance of occasional hot spells or heatwaves, especially further to the southeast. However, around the turn of the month, there is a signal for perhaps more widely unsettled weather to develop, though the details of this remain rather uncertain.
