    __________________________________________

    Requests sent out for the bonus question dates (two missing that) ... Con Sensus subject to adjustment for any later entries ... for the location of the coldest max, the choices were

    Mullingar 5, Knock 5, Ballyhaise 5, Mountdillon 6 (Con scores 3 if any verify)

    Oak Park 4 (Con scores 2 if OP verifies)

    Dunsany, Claremorris, Gurteen (Con scores 1 if any of these verifies)

    any other location (Con scores zero, forecasters score from performance of their location relative to actual coldest, i.e., location is second coldest, 2 points, third coldest 1 point).

    Overall scoring for bonus, 5 for value, 2 for date, 3 for location, 1 and 2 superbonus points available. ... for date, top third of field gets 2 pts, middle third 1 point, lower third zero.


    Normal scores the same way as Con for location but can get 2 for Markree and 1 for any other location inland not selected or Dublin A, zero for coastal locations and Moorepark.

    Normal scores 2 for date if 25-30, 1 if 18-24, zero if 1-17.

    ================ - ===================

    Slight changes to Con Sensus as a result of later entry ... see my post below for further info about late entry validated MAX or MIN data ... this has been required in a few situations way back when, not very often recently as far as I can recall. Late penalties are not that big a bite nowadays after I reduced them earlier (in 2019 I think it was). Added later ... actual max on 1st was apparently 16.2, so I have removed the "max 15" sticker from Danno's forecast and edited my post about it, also Eon1208 entered later but has a value that is not advantageous from knowing the result on 1st, so just the regular late penalty applies there. Anyone who shows up even later and enters 16.2 or close values will be capped at 15 for that portion.

    Also by the way, welcome to SleetAndSnow who is a regular participant in storm threads but as far as I can recall hasn't entered this contest before this month. Danno of course was quite a regular (and successful) participant many years ago (like when there was winter).

    Okay, will have to mention that when people enter after a likely monthly extreme is set and they quote that value in their forecast, the usual late penalty isn't really large enough to deflate that advantage, so what we have done in past situations like this (can't remember one recently, but obviously it could apply to the forecast just entered), is to cap the MAX score at 15 for that entrant as well as the late penalty. So I trust this will be seen as a fair decision here (and it would apply to anyone else who either entered later than this or a regular asking for a late penalty on revision).

    This will of course not be an issue if the max on 1st is superseded by an even higher value. Will place the forecast in the table with those provisions.

    (later edit) _ Apparently the max on 1st was 16.2, so I have removed that cap of 15 points on a forecast that is not conclusively based on a known result, poster could be thinking 16.4 will verify later in month. And since it's not a regular entrant in the late stages of the annual contest, it doesn't make much practical difference anyway. This is a rule to be applied in relevant situations later though, in case we get another situation similar to this.

    Max 16.2 on the 1st at Phoenix Park. Does that beat the Max for October 20.

    Bonus Question I didn’t see that I had to put in a date for a low max temperature as well as location. So my guess is 28th at Mt Dillon.
