December 2020 Boards weather forecast contest

    1. Predict the IMT (Irish mean temperature, an average for five stations, Casement, Claremorris, Mullingar, Oak Park and Shannon). The 1981-2010 "normal" value is 5.4 C.

    2. Predict the MAX, the highest daily maximum at any reporting station as confirmed at end of month in the Monthly Summary.

    3. Predict the MIN, the lowest daily minimum at any reporting station as confirmed at end of month in the Monthly Summary.

    4. Predict the PRC, the average rainfall expressed as percentage of normal at the eleven stations we normally use, which include the five mentioned for IMT and also Ballyhaise, Belmullet, Malin Head, Johnstown Castle, Cork and Valentia.

    5. Predict the SUN, the total sunshine expressed as a percentage of normal at the six stations used (Belmullet, Casement, Dublin, Shannon, Cork, Valentia).

    6. For the BONUS question, our traditional prediction of MAX and MIN on Christmas Day at Dub (A) and (for 3 point super-bonus), will it snow at any location among the 25 regular reporting stations on the met.ie website, and this includes 24th as well as 25th of December. If you get this right on Yes or No, it's worth 2 points for yes verifying, a correct location is worth 1 more point, but no locations will bring in the "No" scores at 3.

    Deadline for entries will be 0300h Tuesday 1st of December, with 1 point deductions for every 4h late to 1500h Monday 2nd, after which penalties are 1 point per hour (in addition to the 9 points accumulated to that time).

    Good luck !!

    I think the scoring will be very close after this current month ends, but that's just a hunch, I haven't had much time to study the situation.

    ____________________________________________________

    30 forecasts so far, will add in any later ones, gave our two recent late entrants a bit of a break
    on the total points deducted since they aren't in contention for this year's awards,

    for the snowfall question, 15 said no, 15 said yes (Knock 8, Casement 4, Ballyhaise 1);


    consensus looks very close to average, with one forecaster throwing in the towel and taking

    average altogether (and why not you might ask) ...

    Welcome to our new or occasional forecasters, good luck -- November scoring in progress, awaiting confirmation later from MS.

    Well there's no problem in missing this last month, here's what your scoring lines are going to be for the best 10/12

    taking the lines from the last update and blanking out the score, unfortunately 200motels you already missed one month and will draw on your lowest score of 43, while Kindred Spirit will be adding second lowest 48 to the existing total.

    Currently


    08_(11)_ Kindred Spirit_____ 61 _63 _71 _71 _60 _53 _37 _53 _48 _55 _74 __ 646 ____ 561 (07t) (12t)


    17_(15)_200motels ________47 _--- _75 _61 _60 _65 _60 _43 _64 _65 _52 __ 592 ____ 549 (11t) (07)


    will end up

    ??_(08)_ Kindred Spirit_____ 61 _63 _71 _71 _60 _53 _37 _53 _48 _55 _74 _ --- _ 646 ____ 609 (??) (07t)


    ??_(17)_200motels ________47 _--- _75 _61 _60 _65 _60 _43 _64 _65 _52 _ --- _ 592 ____ 592 (??) (11t)

    At this point,

    others in the contest are guaranteed to go up from previous total by their second lowest score (in most cases) so what they actually go up will be the surplus of December over that score. For example, I have mick's score handy since I block copied the small part of the table between your lines, and in his case, second lowest score is 50, so his best 10/12 will be at least 550 + 50 = 600, and if he scores more than 50 in December, then it will go up by that much instead. But if he scores less he will add the 50.

    currently

    07_(08)_ mickger844posts __ 55 _63 _60 _48 _74 _59 _54 _53 _50 _70 _62 __ 648 ____ 550 (10) (11)

    will become

    yada yada 648+DEC ______ 550 + 50 or Dec whichever higher

    ... with the late penalties now in play, you can't beat your reserve scores anyway, I think we're past -50 now.

    My apologies for not contacting you soon after deadline, I only noticed who had not checked in late yesterday and figured it was too late for a solution.


  • Registered Users, Registered Users 2 Posts: 6,047 ✭✭✭appledrop


    Min -1.7 Mt Dillion on 3rd Dec.

    I'd say last night was even colder though.


  • Registered Users, Registered Users 2 Posts: 14,583 ✭✭✭✭M.T. Cranium


    Checked out the mins on 4th, about the same as 3rd, but meanwhile -3 at Dunsany 0700h today.

    A rather cold start to the month and only limited warming shown on model runs, could be running IMT values around 4 to 5 for quite a while.

    A number of stations at -3 at 11pm. I'd say -4 could be possible as night goes on.


  • Registered Users, Registered Users 2 Posts: 1,775 ✭✭✭Bsal


    -4.1 at Dublin airport on the 0100z


  • Registered Users, Registered Users 2 Posts: 14,583 ✭✭✭✭M.T. Cranium


    Too late to edit the table of forecasts but this line

    for the snowfall question, 15 said no, 15 said yes (Knock 8, Casement 4, Ballyhaise 1);

    should read

    for the snowfall question, 15 said no, 15 said yes (Knock 9, Casement 4, Ballyhaise 2).

    If a moderator can make that change then you could also delete this post. (it makes no difference to the contest scoring anyway).


  • Registered Users, Registered Users 2 Posts: 6,047 ✭✭✭appledrop


    So new official min is -3.4 at Dublin airport on 6th.

    However as Bsal noted DA reached -4 overnight + Dunsany is showing -5 at 5am.

    So the 7th Dec data when complied with give us our new min.
