    Enter the temperature forecast contest by end of day Friday, 31 December (2021) or with increasing time penalties on the first three days of January 2022. 

     

    (Optional) EWP forecast contest

    -- Predict the January precipitation (snowfall liquid equivalent so for every 10 cm of snow, 10 mm precip on average), the standard we are using for this contest is the Hadley England and Wales Precip (EWP) and here are the averages and extremes (the period of record is 1766 to present) ...

    184.6 .. wettest January (2014)

    176.8 .. 2nd wettest Jan (1948)

    146.0 .. 2021

     95.8 .. --- average 1992-2021 ---

     94.2 .. --- average 1991-2020 ---

     93.0 .. --- average 1981-2010 ---

     81.7 _ average of all data 1766 to 2021

     16.5 .. driest January in recent past (1997) -- 5th driest since these records started in 1766

     15.3 .. second driest January on record (1779)

     04.4 .. driest January (1766)

    Notes: The recent past has seen several quite wet months besides 2014, 1988 (169.0 mm) was third wettest, 1995 (162.6 mm) was fourth wettest, and 2016 (149.5 mm) was 8th wettest while 2021 (146.0 mm) was 12th wettest. Jan 2020 had 82.5 mm, while 2019 was a relatively dry 47.1 mm, and Jan 2018 was slightly wetter than average at 104.5 mm,  2017 produced 79.6 mm and 2015 had 101.0 mm. Dry Januaries have been rare in recent decades. Aside from 1997, the only cases since 1981 to record 40 mm or less include 1987 with 33.9 mm, and 2006 with 31.9 mm. 

    To enter the precip contest, forecast the England and Wales precip for Jan 2022, to nearest mm (and tenth if desired). You can add this to your temperature forecast or place it in a separate post. Same deadlines, scoring is to a maximum of 10 points each month. 

    __ Good luck !! __

    Bang on 4*C please, and 70mm of rain and snow. Tar!

    See it being quite a chilly one, but still with some milder outbreaks at times.

    5.2C and 130mm.

    Bit of a 'hedge your bets' as opinions, and models, are currently split between something very mild and something colder.

    I'm anticipating something rather like 1994, 1998 or 2004 on balance. Perhaps, like 1994 or 2004, predominantly mild and wet, but with one or two short and potent perhaps snowy spells. Or, a 1998-style two-thirds mild and wet, one third cold and dry setup. Expecting February to be drier.

    Two months in row I've gambled that we'll spend more time on the south side of an amplified jet stream than otherwise.

    I've learned my lesson. 

    6.5c and 127mm please.
