This Evening and Tonight:

Evening sunshine before cloud arrives from the north overnight. Mostly dry, although perhaps some heavy showers developing towards Kent and London, small risk of thunder. Another warm and humid night. Minimum temperature 18 °C.

Wednesday:

A cloudy start across the region with thundery rain possibly affecting parts of Kent and Sussex at first. Increasing sunny spells spreading in from the west, feeling fresher than late. Maximum temperature 27 °C.

Outlook for Thursday to Saturday:

Thursday brings a fine day with plenty of dry and sunny weather. Another fine day of Friday with hazy sunshine. Turning unsettled on Saturday with cloud, wind, and occasional rain.

Cloud and rain associated with an Atlantic frontal system and area of low pressure is likely to sweep south and east, with rain always most persistent on western hills, especially western Scotland where large rainfall totals may have built up by this time. Eastern areas in shelter could see warm and humid brighter breaks, but with a risk of thundery showers, which could be slow moving at first. Likely turning cooler and more showery into next week, followed by a changeable pattern with further areas of cloud and rain and brighter, more settled spells in-between. Temperatures are likely to be around average overall, with an increasing chance of warmth in the south as the period progresses.

Changeable conditions with a predominantly northwest to southeast split in temperature and rainfall, and the potential for further occasional episodes of hot weather and thundery outbreaks, are considered likely to gradually give way to something more settled and dry overall through the second half of July. Temperatures are likely to be above average, with the greatest chance of very warm or hot spells in the south or southeast.
