Late August bank holiday

There is still over a week until the bank holiday, which means there is plenty of time for the prospects to change. Also, at this time of year the impact of ex-hurricanes and tropical storms can add to the uncertainty. In particular, at the time of publication there are indications that the remnants of Hurricane Ernesto will be making their way towards the UK as the bank holiday weekend approaches.

High pressure not likely to dominate

Computer models are suggesting the bank holiday weekend will be quite mixed. High pressure building from the southwest is likely to have influence at times. The uncertainties are how much influence and how far north it will extend.

Therefore, in general terms the wettest periods are likely to be in the north and west, with drier ones focused on the south and east. That said, some computer models are showing wet and windy weather affecting the southern half of the UK early on.

The chart below shows forecast pressure patterns for Sunday 25th August. It is intended to give an idea of the general theme, not the details.

With high pressure not expected to dominate, there is a possibility of rain bearing weather fronts pushing in from the Atlantic later in the bank holiday period. 

Mixed bank holiday weekend?

At the present time fairly mixed weather is expected during the bank holiday weekend. There is a risk of wet and windy conditions at times, particularly in the north and west. The chance of dry and sunny periods is higher in the south and the east. Temperatures probably won't be too far from the average overall across the UK, but regional variations are expected. In the south it may be warm at times, with the north having cooler spells.
