A low pressure system runs near or across the northwest of the UK at the start of the period bringing some wetter, windier conditions to the northwest. Elsewhere a good deal of dry and very warm or hot weather at first, but it is possible the odd thunderstorm could develop in response to the heat before it turns cooler and fresher from the west by the middle of next week. Beyond this, conditions look like being rather changeable, with some drier spells but also some spells of rain and wind. There is also the chance of further very warm or locally hot and humid weather, as brief bursts of hotter air encroach from the continent, but probably fairly short-lived. Should these occur they bring with them the threat of thunderstorms.

Conditions will likely continue to be changeable through much of July. The wettest and windiest conditions look most likely towards the northwest with a risk of some heavy rain at times, especially over hills. Southern and eastern areas are most favoured for longer drier and more settled spells, although even here some rain or showers will be likely, perhaps heavy and thundery at times. There are signs of more widely settled weather during the second half of July, however this signal is very tentative. Temperatures are expected to be above average for most areas, especially towards the southeast where there will be an ongoing chance of some very warm or hot conditions at times.
