Horndean (Hampshire) weather

Headline:

Warm and humid with a risk of thundery showers.

Today:

Any early mist and fog patches soon clearing to give a very warm and humid day with the risk of isolated showers, a few of these perhaps turning heavy and thundery during the afternoon. Winds generally light away from showers. Maximum temperature 30 °C.

Tonight:

A muggy night with showers gradually dissipating, before areas of heavy, thundery rain move across the region later in the evening and continue into the early hours of Saturday morning. Minimum temperature 18 °C.

Saturday:

Turning slightly cooler and unsettled with widespread, often heavy and thundery rain or showers lasting much of the day, likely clearing into the evening to give another muggy night. Maximum temperature 25 °C.

Outlook for Sunday to Tuesday:

Remaining unsettled, with a mixture of sunny spells and rain or thundery showers throughout the period. Feeling warm in any sunny spells and breezy at times towards the coast.

Overall a rather more changeable pattern of weather through this period, compared to much of the summer thus far. Tuesday will likely see a continuation of heavy, perhaps thundery showers, although the focus may be more across the north and east by this stage. Thereafter, a general westerly regime looks to become established, with occasional weather systems moving in from the Atlantic. This means further rain or showers and breezy conditions at times, especially in the northwest. This will be interspersed with some drier, sunnier periods. Temperatures are expected to average out above normal with some humid conditions possible at times making it feel particularly warm in any sunshine. This broad pattern is likely to continue through to the end of July.

The rather changeable pattern will likely continue through early August with spells of rain or showers mixed in with some drier, brighter days. Towards mid-August, there are tentative signs that high pressure may become rather more dominant, which could bring more in the way dry, settled weather more widely. Temperatures will likely continue to be above average overall, with the possibility of very warm or hot spells developing later in the period, especially further south and east.
