I will start with Feb.....
Feb 2020 - Mildest in recent years. Settled and foggy mid month but ending with an horrific storm to rival Oct 1987.
March 2020 - A weird month starting stormy, segueing into the only real ‘winter’ weather of the season with a wet snowy early period and staying a little below average before an insane warmup near the end. Vet just below average at 6.2.C which will be lower than any of the 3 ‘winter’ months we have just had.
April 2020 - A prolonged spell of dry weather with very warm daytime highs and cool nights. Record CET of 12.1.C
May 2020 - Vacillating between unseasonably high temperatures exceeding 30.C courtesy of a very warm continent (breaking many May warmth records) and cooling off and stormier periods, CET close to 15.C so warmest in recent years.
June 2020 - At last a genuine ‘flaming June’ with insanely high temperatures on the Continent exceeding 40.C and our first ever temp above 39.C. CET running above 20.C until mid month thereafter the weather steadily degenerates into a succession of unseasonable Lows with a disappointing cold wet end. CET of 18.C, high but not a record.
July 2020 - The severe heat will shunt off into Eastern Europe and Russia with some places exceeding 50.C there. We will be left with a strangely autumnal feeling month of Lows and rain which will put the kibosh on the CET at 15.9.C
August 2020 - Very tops turvy, with an unseasonal cold snap early on bringing frost and even snow in places. Thereafter a High pressure over the continent will feed the warmth of Eastern Europe and Russia in a Heat of the East event sending temperatures over 41.C in the UK with a nighttime low of 28.4.C Sadly this heat will be a transient several day feast before terrific thunderstorms clear it off and resume normal Atlantic service before Bank Holiday. CET of 19.6.C, a record for August if not overall.
September 2020- The bank of heat in Europe will return, with an absolute outlier of a month and Mediterranean conditions. CET of 19.1, record breaking and outrageous for the time of year.
October 2020 - The 1st will see a 30.C day before the heat gently subsides but continues to cool as the dominant High gains a rather wicked Siberian origin and the end of the month is more of a Oct 1997(?) with severe frosts and fog. CET 13.0.C, near record warmth, a record killed off dramatically by cold of last few days.
November 2020 - An unusual early season snowfall followed by a fairly Atlantic month but with much needed rain after a very dry Autumn. CET of 10.1.C
December 2020 - Like December 2015 on steroids until Christmas, 19.4.C recorded. An Arctic snap and Twixmas snow pulls the CET back to 9.5.C by end.
Also in 2020s...
2021 - very wet Autumn indeed.
2022 - Highest CET monthly value of decade in August 2022. A relentless heatwave seeing 40.C somewhere for over a week and the Met Office to issue a Level 4 warning.
2029 - A trial of the Urban Heat Island Cooling project which sees freshwater pumped from deep underground at dusk on the hottest evenings in parts of London and Birmingham onto buildings and roads. Locally shown to reduce temperatures temporarily by over 8.C and daily means by over 2.C. Widely employed technology by 2030s that actually inverts the effect of the urban heat islands in warmest days.
