    With the prospects of some Spring warmth, we mustn't get complacent at this time of the year as there can be drastic changes. It can easily can go from warm Spring sunshine to Winter frosts and snow in a space of a couple of days, I call it "Switch Around". Spring is the season when such drastic changes are at their greatest.

    Here's a selection of past "Switch Arounds"

    There was another striking one I recall in early May 1995; temperatures here were peaking at around 25-26C after a warm week by the 6th but on the 8th (the VE day holiday) were struggling to reach 10C, as they did for the following 10 days; there were airfrosts and even snow.

    There was a fairly notable one at the end of March 1995 also, at least in this part of the North East: 15C max on the 23rd, but maxes of around 4C on the 27th and 28th:

    There were also strong temperature falls around 28 February-2 March 1995 and also 12-15 March 1995, though not as dramatic. I also remember the mild spring of 1999, with the isolated but potent northerly spell around the 13th-19th April.

    Was there not a rapid drop in temperatures in the lead up to Easter 2003?

    It was just before I began recording temperatures so I have no stats.

    However, I recall visiting my brother in Southampton on Maundy Thursday with temps of about 24c/25c and everyoine wearing shorts/t-shirt. Then Good Friday was about 21c with warm sunshine, but an E'ly wind picked up which led into a bitterly cold feeling Easter Saturday - I recall shivering at football that afternoon.

    It would be interesting to compare the switcharound this year between the 4th and 6th, I would expect it to give some of the others quoted a run for their money.

    Could this be done?

    One of the great switch-arounds (4th April to 6th April 2008). Snow falling and lying added to the effect more so than just a mere temperature drop.

    Jeez, some real drops there. Perhaps slightly too late in the season but in May 2005 for Bristol:

    27th: 28.1C

    Thanks for posting these. Gosh, the 4-6 April 2008 event wipes the floor with most of the others you have put up, indeed places like Gatwick saw an unprecedented switcharound. These figures are evidence that last weekend was a very notable switcharound indeed. Exceptional stuff.

    Some places reported lying snow that morning of the 4th April 1990 such as Manchester. I remember waking up to a covering of snow from showers that fell during the early hours.

    April 1981 It was quite sunny in the first half, particularly in the north. In some places it was the warmest first half of April for twenty years, but the second half as the coldest of the century; hence temperatures overall were not too far off average. It was cloudier at times in the south, with some rain. Thunderstorms gave 83.6 mm of rain at Horsham on the 14th, leading to severe flooding. 86 mm of rain fell at Horsham (Sussex) on the 14th. Around Easter most of the country was cloudless. Cold weather came south from the Arctic on Easter Monday, the 20th, as northerly winds set in. Then very cold air swept south on the 22nd, interacting with a complex low moving east across the Midlands to bring snow. It was -11C at Dalwhinnie (Highland) on the night of the 23rd. There was a maximum of only 1C at Leeming (Yorks.) and Nottingham on the 24th. From Birmingham to Nottingham the afternoon maxima did not exceed 3C from the 24-26th. In hilly districts the temperature remained permanently subzero. There was a great blizzard with thunder on the 24th and 26th; particularly affecting the Pennines, the west, southwest, and even Salisbury Plain and the Cotswolds. Thunder and northerly winds of 40 mph. There was 20 cm of snow on the night of the 25th across southern and western England and Wales: 66 cm was reported in Gloucestershire. Level snow of 60 cm around the Peak District with 20' drifts reported. The snow was wet and drifted in very strong winds: 20' high drifts were recorded in Derbyshire and Staffordshire. The Snake Pass in Derbyshire was closed because of the risk of an avalanche. There was widespread disruption to power supplies, farming (particularly on Dartmoor), particularly livestock, and traffic. The thaw led to serious flooding in the east Midlands, in some places the worst since 1947.

    Wow. You'd never get that much lying snow in London in April these days.
