AFTER days of basking in the balmy sun it may be time to take cover in West Berkshire with heavy storms forecast for later today and tomorrow.
Thunder and lightning with rain and hail could be on the way as the Met Office issue a yellow weather warning for the region across Thursday and Friday.
From 3pm today (Thursday) slow moving thunderstorms are forecast which could lead to torrential downpours with conditions expected to worsen overnight (Friday).
The Met Office chief forecaster said: "Isolated thunderstorms developing later on Thursday are expected to become more widespread across southern, central and eastern parts of England overnight and during Friday morning, whilst more isolated downpours may develop further north and west ahead of an eastwards moving cold front.
"This brings the risk of 30-40 mm of rain in an hour in places and more than 50 mm in a few hours.
"At this stage, there remains uncertainty in the location of the most disruptive thunderstorms, although the area south of a line from The Wash to Bristol is considered to be at greatest risk during Friday morning."
Following the warning Park House School in Newbury has decided to postpone tomorrow's sponsored walk to Monday.
A statement on the school's website said: "Due to a yellow weather warning and the high risk of lightning, the sponsored walk planned for tomorrow (Friday 16 September) will now be postponed until Monday 19 September."
