Borehamwood (Hertfordshire) weather

Headline:

Turning unseasonably windy on Monday with periods of rain.

This Evening and Tonight:

Generally dry and clear initially but cloud gradually thickening from the west after midnight, though most parts should stay dry. Mainly light winds increasing in strength later. Minimum temperature 13 °C.

Monday:

Rather windy and cloudy Monday, with outbreaks of rain, heavy at times, moving east through the afternoon, followed by dry and brighter conditions later. Maximum temperature 24 °C.

Outlook for Tuesday to Thursday:

Blustery winds Tuesday with sunny spells and the odd shower possible. Winds ease Wednesday, largely dry with sunny spells. Breezier and cloudier Thursday but mostly dry. Temperatures trending warmer later.

This period likely starts with something of a north-south split. Some locally heavy rain or showers, with a risk of thunder, will likely affect the north, along with some strong winds, whilst the south looks like starting mainly dry with some warm sunshine and lighter winds. There is a chance of some rain or showers even in the south, but more likely it will be mainly dry and warm here. Temperatures will probably be close to average in the north at first. As we move towards the middle of the month, there is an increased chance of high pressure becoming more dominant, leading to drier, more settled conditions becoming more widespread with above average temperatures. However, some brief unsettled spells remain possible, particularly towards the end of this period.

High pressure, and therefore fairly settled conditions overall, appears most likely for the second half of August. Although dry weather is likely to dominate, periods of rain or showers and thunderstorms may develop at times, these perhaps more likely later in the period. Above average temperatures overall seem most likely, with the potential for hot spells to develop, especially in the east and south.
