The SE was particularly warm. There was some severe flooding in NE England at the start of the month, with Todmorden and Hebden Bridge aprticularly badly affected. Heavy prolonged rain gave 50-75 mm on the 2-3rd. Then another 50 mm or so fell in thunderstorms from the south at the end of this wet spell. The extra rain on top of saturated ground led to flooding. Severe gale midmonth, affecting Scotland on the 12-13th: gust of 83 mph on Stornoway. The pressure at the centre of the depression that caused this was 968 mb, the lowest June pressure in British waters since the D-day storm of 1944. Brief hot spell midmonth (17-19th): 32C in Leeds on the 18th; 32.6C at Colthishall (Norfolk) on the 19th. The heat was accompanied by some very low relative humidities: 20% was widespread across the south on the 18th, with Brize Norton (Oxon.) recording 11.5%. Overall it was slightly less sunny than average, with Birmingham only getting 66% of the average.
