Potters Bar (Hertfordshire) weather

Headline:

Temperatures slowly rising this week becoming hot by the weekend.

Today:

Perhaps on the cloudy side in the east with isolated light showers possible at first. Drier and brighter further west with the best of warm sunny spells, though all parts will see a fine afternoon. Breezy at first, easing later. Maximum temperature 24 °C.

Tonight:

Mostly clear overnight with light winds, perhaps the odd patch of low cloud near the coast and some high cloud moving into the west by dawn. Minimum temperature 7 °C.

Wednesday:

Cloudy in the west at first but staying dry. Fine further east with warm sunshine spreading to all parts through the afternoon. Light winds. Maximum temperature 27 °C.

Outlook for Thursday to Saturday:

Temperatures increasing in fine and often sunny weather. Winds will fall light with potential for very warm and humid conditions before the weekend. Early coastal mist patches will be short-lived.

Settled at first, with very warm or hot weather quite widely across the UK. There is a small chance of a few thunderstorms, but most areas will likely be dry. Early next week, a transition to less hot conditions is expected, but with uncertain timing. This could bring an increasing chance of some rain or showers, perhaps thundery, but there is scope for very warm or hot conditions to persist in more eastern and southern areas. Beyond midweek, a rather changeable pattern is anticipated with some rain or showers possible at times, which could be heavy and thundery, but interspersed with drier interludes. Whilst a downward trend in temperature is anticipated, it will still likely be warmer than average, especially in the south and east where hot spells 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.
