Upavon (Wiltshire) weather

Headline:

Dry for many with isolated showers on Thursday.

This Evening and Tonight:

The chance of an isolated shower at first, but most places staying dry this evening and overnight. Clear spells are likely at times and turning rather chilly inland with a few mist or fog patches forming where skies remain clear. Minimum temperature 4 °C.

Thursday:

A dry day for most but isolated afternoon showers are possible. Cloudier in the west with low cloud and fog in west Cornwall. Pleasant in any sunshine with light winds. Maximum temperature 17 °C.

Outlook for Friday to Sunday:

Sunny spells on Friday but rain possible in the west later. Saturday starting damp in places, but an increasingly bright weekend thereafter. Occasionally breezy but feeling warm in any sunshine.

Most likely starting off widely fine with sunny spells, following the clearance of early morning mist and fog. This most likely in the south, whilst in the north there's a greater chance of more cloud which may take some time to clear. There's a small chance that fine and very warm weather could extend right across the country over the following days, but it's more likely that cloud/rain in the northwest will sink southeast introducing more changeable and cooler conditions for a time mid-week. It then becomes roughly equal chances that we see a resumption of mainly fine and dry conditions versus a continuation of more changeable weather with a mixture of rain and drier interludes.

Forecast confidence is lower than average for this range, although fairly typical for late Spring. A typical mixture of drier and settled periods, and periods of wetter and more unsettled conditions, is on balance slightly more likely than predominantly unsettled or predominantly settled. Temperatures are likely to be around average overall, with a slightly increased chance of warm or hot spells. Any such spells could be accompanied by locally heavy showers and thunderstorms.
