January 2018 Boards weather forecast contest

Here's where things stand after the first week ...

IMT was 4.7 which is 0.6 below average; the weekend more than compensated for a generally mild first five days.

MAX is 13.4 and during the week MIN was --5.5 but has since fallen to --6.7 this morning (see above posts).

PRC was 134% of normal. While all eleven sites were above normal, only Malin Head at 243% and Belmullet at 170% were appreciably above that average, in fact all nine of the others were below it and averaged 114%.

SUN averaged 160% of normal (962/600) and most of that work was done over the weekend. Despite this, Casement was slightly below its average (only Sunday 7th had much sunshine there). Normal appears to be around 1.7 hours a day on average at this time of year.

We interrupt your slumber for this second week update ...

IMT now at 4.3(4) after a somewhat chilly second week that averaged 4.0 (1.2 below normal).

MAX remains 13.4 and MIN --6.8

PRC now 125% of normal, the second week averaged 116% and was almost the opposite of week one with heavier amounts in the south, below average in the north.

SUN fell to 113% with this past week only 76% (456/600), the southwest was mostly overcast all week, slightly above normal values from the northwest and east.

Getting ready for Wednesday night's possible assault on the bonus values and locations which are 53 Mace, 84 Knock.

Well, I finally got around to doing this update ... after three weeks ...

IMT is 4.5 C (range is 3.8 Mullingar to 5.7 Shannon) and the third week averaged 4.8 which was 0.4 below normal. It must have come up fairly sharply on Sunday 21st as the IMT for the day was 7.8 C). I think this might bounce up and down but stay in the 4's probably a bit higher at the end than now, perhaps 4.7 or 4.8 would be favoured (by latest guidance).

MAX now 13.7 and MIN remains --6.8.

PRC is now up to 158% as the third week was a soaker at 224% of normal. Even with 50% in the last ten days this will finish around 120% so most of us will be hoping that it stays rather dry.

SUN is now closer to average at 107%, the past week had 95% (572/600). This is about where it might finish up as there will be some sun at times and it doesn't take much in January.

If no further change to max and min, and my estimates are close, also bonus settled by earlier events, then highest score I can see would be Con around 87 but some of you will be close and might edge past Con if your PRC or SUN forecasts are better than my estimates. Mickger844posts has almost the same total score from my estimates (this could all change of course, just saying). NormaL would score about 80 and could edge up to meet Con if the IMT is closer to 5.1 or above. Lots of fairly decent looking scores anyway. As a group we are quite good at this, the power of many minds sort of a thing ...

Update through four weeks ...

IMT on 5.4 with this past week quite mild, 8.1 C (+2.8 deg). Should finish close to 5.2 C.

PRC still very high at 153% with this past week near 140%. Likely to finish near 150%.

SUN limping home near normal, 103% now with this past week at 92% (553/600). May rebound to above 105%.

The Monthly Summary confirmed all values used except for SUN which came in higher, and I realized why after the fact, when I estimated the impact of the last three days I overlooked the 29th which had about five hours at all sites. So the three-day period had about 170% of normal sunshine, boosting the overall average to 110% of normal.

This will generally change all scores up or down by one point. So here's the revised table.

____________________________________________________________

* Minimum progression rule was necessary for PRC, highest forecast was 134%, did not qualify to limit boosted scores (131 to 137 would have done so).

Scoring for max wind and location was based on 4 points for wind values and 1 for correct location, disregard discussion below forecast entries as that was based on a different scoring assumption. Nobody qualified for superbonus scoring (one did but was capped at 8 points by later entry than events, ^symbol indicates one point not counted when 8 points reached).

Assuming all other variables are confirmed by MS, the SUN scoring is based on 105% and will be adjusted where necessary after final reporting.

Congrats to waterways, tae laidir and mickger844posts for leading the way in the first contest of 2018, generally good scoring results for most.
