The snow event was of particular note for its lateness in the season and its intensity. Also associated with the pressure system was low temperatures. On the night of the 23rd, the temperature at Dalwhinnie fell to {{convert|-11.0|C|F|abbr=on}}.[2] Snowfall totalsTotals across the southern England, Wales, the Midlands and the North West widely exceeded {{convert|30|cm|in|abbr=on}}. On the 25th alone, {{convert|20|cm|in|abbr=on}} were reported to have fallen across southern and western England and Wales. In total, {{convert|66|cm|in|abbr=on}} was reported to have fallen in Gloucestershire. Also, there was level snow of {{convert|60|cm|in|abbr=on}} around the Peak District with {{convert|20|feet|cm|abbr=on}} drifts reported in strong winds. Also {{convert|20|feet|cm|abbr=on}} high drifts were recorded in Derbyshire and Staffordshire.[2] TemperaturesAlong with a snow, temperatures were exceptionally below normal for this stage in April. At Birmingham, the temperature didn't exceed {{convert|3.0|C|F|abbr=on}} between the 24th and 26th and in some places, the temperature remained permanently below {{convert|0|C|F|abbr=on}}. The lowest temperature of all was {{convert|-11.0|C|F|abbr=on}} on the night of the 23rd at Dalwhinnie.[2] Usually at this stage in April, the temperature would be expected to reach around {{convert|16|C|F|abbr=on}}. Impacts and aftermathThe snow thawed very quickly, this led to major flooding in areas such as the east Midlands. In some places it was the worst flooding since the thaw of March 1947. There was also widespread disruption to power supplies, farming (particularly on Dartmoor), particularly livestock, and traffic. And also the Snake Pass in Derbyshire was closed because of the risk of an avalanche.[2] References1. ^1 {{cite web|url=http://www.wetterzentrale.de/reanalysis.php?uur=1800&var=1&nmaps=24&map=1&model=noaa&jaar=1981&maand=04&dag=22|title=Reanalysis archives|first=Rogier|last=Floors|website=www.wetterzentrale.de}} {{Heat waves in the United Kingdom}}2. ^1 2 3 4 {{cite web|url=http://www.trevorharley.com/weather_web_pages/british_weather_in_april.htm|title=British weather in April|website=www.trevorharley.com}} 1 : Snow in the United Kingdom |
