Lord's Marylebone C.C. (Greater London) weather

Headline:

Hot or very hot again on Tuesday.

Today:

Very hot for most and remaining humid with long spells of very strong sunshine across the region. Some mist could affect southern coasts, especially towards Sussex and Kent. Winds remaining light. Maximum temperature 34 °C.

Tonight:

Fine start before low cloud advances south-westwards across London and Kent with possible light drizzle. Thundery rain probably reaching Sussex and Kent around midnight, before spreading northeast-wards overnight. Minimum temperature 15 °C.

Wednesday:

Cloudy in east with further thundery rain eventually clearing Kent during Wednesday afternoon. Clearer skies with warm sunshine over western areas reaching all parts by evening. Mostly light winds. Maximum temperature 26 °C.

Outlook for Thursday to Saturday:

Dry and bright Thursday and Friday with some cloud. Chance of an afternoon shower on Thursday. Saturday breezy with increasing chance of showers or rain. Temperatures remaining above normal.

Following a fine couple of days in the run up to this period, away from the far northwest where more persistent rain is expected to develop, a transition to something more unsettled countrywide looks likely. 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 whilst some eastern areas in shelter could see warm and humid brighter breaks. Likely turning cooler and more showery later in the weekend and 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.
