Issued at: 1234 on Sun 28 Jun 2015

There is an 80 % probability of heatwave conditions between 1200 on Tuesday and 0600 on Thursday in parts of England.

Temperatures are expected to build on Tuesday 30 June and into Wednesday 01 July, with the hottest day of the year so far expected on successive days this working week. There is still some uncertainty regarding peak temperature values on these two days, however the highest maximum temperature is expected on Wednesday. Confidence in warm and humid nights to end Tuesday and Wednesday is currently much higher. A final area of uncertainty is the longevity of the episode, with temperatures currently thought likely to moderate from the west on Thursday as the warmest air gradually transfers eastwards.

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://www.metoffice.gov.uk/public/weather/forecast/#?tab=map
