Met Office Level 3 - Heatwave Action

There is a 90 % probability of Heat-Health Alert criteria being met between 1200 on Tuesday 09 Aug and 2300 on Sunday 14 Aug in parts of England.

High pressure dominating this week, with fine and dry conditions across most of the country, prolonged sunshine, and light to moderate breezes. Temperatures rising from warm or very warm to locally hot in most regions, with a focus of the warmest weather in central-southern England. Headline max temperatures reaching mid 30's, most likely Friday or Saturday. The biggest uncertainty is over the end of the hot spell, with thundery showers expected to arrive from the south through the weekend introducing cloudier, somewhat cooler conditions. Confidence in the details of these showers remains low however with potentially for a continuation of warm or very warm temperatures into next week for some areas before we see a gradual return to around average.

An update will be issued when the alert level changes in any region. Alerts are issued once a day by 0900 if required and are not subject to amendment in between standard issue times. Note that the details of the forecast weather are valid at the time of issue but may change over the period that an alert remains in force. These details will not be updated here unless the alert level also changes, the latest forecast details can be obtained at the following link:http://http://www.metoffice.gov.uk/public/weather/forecast/#?tab=map
