Early provisional statistics for April (1st-26th) show that overall it has also been a sunny and warm month so far compared to the long-term 1981-2010 average.
Following on from the mid-month statistics, Middlesex remains the driest historical county with 2.7mm of rainfall so far this month just 6% of the long-term average for April which is 45mm. In comparison Sutherland has so far been the wettest historical county with 130.8mm of rain, 41% above the expected monthly rainfall.
The UK as a whole has seen just 41% of the average April rainfall; the wettest region has been Scotland with 62.5mm and the driest southern England with 8.1mm.
It is likely many of the rainfall statistics will change as we expect an area of low pressure to move in from the south-west over the Bank Holiday weekend. As a weather front pushes eastwards across the UK on Sunday and Monday, we could see 10-15mm of rain in some areas, especially in the south-west.
