Well, it's hard to argue with persistence of the extreme warmth, but at the same time there's some very cold air masses at times, still the second half of the month could go very warm again ... I think it will be 2 deg lower than these at mid-month for most of them, then more torchyness.

Roger Smith · March 2, 2017

Hello, glad to see you're okay and sorry to hear of any troubles in the background, I sent you a PM and I hope you can live with the relatively small late charge (I shaved off a fraction as I had done earlier with the other two late ones, this is what I usually do, overlook the fractional part and round down not up).

<<< --- UPDATE on SNOWFALL CONTEST 2016-17 --->>>

The first table is the current standings showing errors to date. Errors in red represent forecasts that are at last update lower than actual amounts, and where errors could increase. Errors in black are cases where you haven't reached your predicted value yet and these errors can decrease (until you do reach your target). Your total error is shown in the last column. This table will be updated whenever snow falls. Meanwhile, the second table is the table of forecasts from November.

... between these tables, new feature added March 13, total error based on assumptions of future snowfall this season ... this feature was updated after the actual amounts on 14th.

... UPDATE _ Apr 7 _ 1.2" added at BOS on Apr 1st and 0.1" at DEN on 4th.

... UPDATE _ Apr 30 _ 2.4" added at DEN on Apr 29th.

_______________________________________________________________________________________________

PROJECTED TOTAL ERRORS for these assumptions of additional snowfall .... assumptions have been revised after reviewing amounts that fell on March 13th--14th. These may be revised again. BOS revised after 1.2" of 9.4 fell on April 1st. DEN revised by 0.1" Assumptions were changed on April 7th. A final change was made on April 30th, namely that the current order will stand because it seems unlikely that DEN will get more than 7.3" (the smallest residual left to be used for any forecaster, RodneyS), and all other stations are now most likely finished for the season. Any snowfall of 7.3 to 13.4 at DEN will drop RodneyS and Damage in Tolland by several ranks. The leader, Mercurial, will only lose ground to other forecasts if more than 13.4" falls at DEN.

Comments:

8th _ (It may be another GFS figment but it certainly looks cold in the east and central regions mid-month to 24th ... I have gone rather conservative in case this is rolled back into the warehouse closer to the time).

11th _ I knew I could get it to turn cold by finally predicting warm.

(15th) _ The cold regime looks like it wants to fade out in the east in last ten days and this usually means a huge torch in actual fact, so I went perhaps a bit warmer than strict map guidance alone. Even so, the projected outcomes are lower than almost all forecasts until we reach the west, then rather warm.

(16th) _ Updated again to be more confident of values for preliminary scoring tables. My assumptions for 23rd to 31st are generally on the warm side of options but would still leave outcomes below most forecasts.

(20th) _ Trying to find some points for the very warm group, have bumped up some of the projections slightly. But NYC and BOS are running generally below the field, extreme forecasts likely there and also for DEN and PHX. We were on to IAH enough to make an extreme forecast less likely there.

(23rd) _ Some minor changes to end of month projections will generally drop most scores a little although helping at SEA for most.

(25th) _ Changes made to ORD and NYC both down 0.5, still looking at a warming trend but the numbers fell short of the previous estimates there. BOS will have to skate hard to get to -2.0 but as that's below all forecasts anyway, will ride that to the finish line and adjust as required.

(26th) _ Changes made to ORD, NYC, BOS and PHX will generally take away 40 points from the field except for a few brave souls who went cold at ORD, they will gain by losing only 20 (this is for those who are not already at zero points now) as all the others were already outside the range of forecasts.

(27th) _ Basically a trade in points between DCA (down) and ATL (up) for most today. BOS may have trouble making even my grim estimate.

(28th) _ Warm sector avoidance pushes NYC and BOS further down into no man's land.

(30th) _ More erosion of pointage, where did we (almost) all go wrong?

(April 1st _ 14z _ Final anomalies are posted above, scoring will soon be final).

... ... ... ... ... ... ... (see post 26 for March scoring) ... ... ... ... ... ... ... ...

Best scores: The first six numbers refer to the six locations, the last two refer to eastern and central division totals. Months won (in this part of the contest) are shown by name after the number codes. Example, RodneyS had best scores for BOS, ORD (in March) and also for the central total (in March), and was high score for March. There are sometimes ties so the totals may add up higher than the number of months. Meanwhile, best total scores Jan-Mar are highlighted in red in the table for six locations, and in bold italic for two groups and for all six.

Roger Smith · April 2, 2017

I have been thinking about this problem with many (almost all) forecasters scoring zero despite large differences in their forecasts.

This is due to a flaw in my approximation of the correlation scoring method. It works fine on the same side of zero (your forecast and the actual anomaly) and expands to fit larger anomalies, but when we run into this situation of all the forecasts being wrong sign and way off, then a 5 degree error gets the same score (zero) as a 10 degree error.

I will work on a refined scoring technique and adjust the scores in the spirit of fair competition, it's not really a change in my method so much as a response to an unforeseen issue (this basically didn't happen in 2014-16, we adjusted alright to very large anomalies by expanding the scoring "net" but this recent streak of missing the right sign is new and gives us an unreliable outcome.

I think the best solution will be to score all months the usual way then boost the scores when the highest score is under 50, and when two thirds of the field or more score zero. Where that happens, the maximum score will be set as follows: where 35 or less, it will go to 40, and where 36 to 49, it will go to 50. If anyone scores higher than 50 (other than Normal), then no adjustments will be made. So you can more or less skunk the field but you have to score 51 or higher.

After some consultations, I have decided to make this the official scoring method. The changes in the annual scoring will be seen in the final (edited) post in this thread. They are mostly minor in terms of change of ranking, and give the field a boost of 20-30 points overall. But this method will separate out the weak from the very weak forecasts in these odd cases.
