The last week of June saw the hottest day so far this year, temperatures of 30 c recorded at Blackpool. Followed within days by (possibly) the wettest day ever recorded in Cumbria.
The Jet Stream flows south of the UK and the North West sees Atlantic lows, slow moving, so rain lingers over Cumbria. June is wetter than normal with rainfall totals mounting to 50 mm, by Monday 29. Double that on the high fells.
