____________________________________________________________________________

median of 16 forecasts for consensus is average of 8th and 9th ranked.  

where Normal changes color (to purple) it is also coldest, for human forecasters the extremes are marked in red and blue.

__ Edit made on April 18th was to put forecasts in correct order. Please note, I have made slight adjustments to scoring in January and March, no changes were needed for February. The changes are explained in the March thread. This is in response to the problem of having several months that turned out much different from most forecasts with a change in sign involved -- this did not fall into the already-existing expanded error range for cases of large anomalies, so I have scored low-score months from an essentially rank-ordered correlative method that removes most of the zero scores that were in the tables. Let me know if you think this is working more fairly, I think it is (and my rank went down as my zero scores were more earned than most of them). :)

Anomalies and projections will be updated every second day 20th to 28th and then on 29th and 30th ... yet again reality seems warmer than our forecasting range (in the east anyway).

(03z May 3) _ Final anomalies appear in bold, now that  DCA have confirmed the provisional value of +7.0 ... that happy circumstance means that our tables are already final. 

__ 2.4" snow at DEN on 29th, have updated the snowfall contest in the March thread, will make a final report in the May thread as DEN can record snow to at least Memorial Day. However, if we assume all other locations are done for the season, DEN needs 7 inches more to affect any of the current rankings (RodneyS in second place has the lowest DEN residual to use up) and contest leader Mercurial has 13.4" left for his DEN forecast.

No problem the way most of us are edging slowly ahead with dozens of points every month. :)

(check the March thread, I adjusted all scoring so that we didn't have all zero scores from a range of forecasts, now there's a guaranteed minimum progression of scores based on some rather low arbitrary high scores of 40 (where the old system gave 35 or less) or 50 (where it was 36-49). but when anyone gets a non-adjusted score above 50 the field has to go off the basic scoring still. So it rewards those who are bold and accurate. We had an expanded metric for those cases where most were on the right side of normal but too timid, but this brings the same sort of spread to the cases where people are also on the wrong side of normal in general and outside the normal scoring zone. It didn't really change the order that much but one or two people will notice that this method gave them a bit of a boost for forecasts that were closer than most (better than most).

Since these two posts have appeared, I should mention that the anomaly countdown is now two posts back, and some provisional scoring will be posted tomorrow after the 18th update (I plan to update after tomorrow every second day with this trend of warmer than all forecasts continuing its ugly path of destruction).

Extreme Forecast Update

 

Oops, we did it again ... five more extreme forecasts qualified making it a total 25 out of 36 so far this year. 

 

DCA finished at +7.0, a win for the highest forecast of +3.0 (dmillz25).

NYC finished at +4.2 with a win for RJay at +2.5.

BOS finished at +3.5, another win for RJay with a forecast of +2.0.

ORD finished at +4.8, that's another win for RJay at +4.0.

ATL finished at +5.8, a win for Damage in Tolland (+3.0).

IAH dropped out of contention and finished at +2.2. 

DEN also dropped out of contention with the finish of +1.5 close to consensus.

PHX ifinished at +2.6, and the third highest forecast (+2.7, RodneyS) is high score, so not quite an extreme forecast.

SEA was also won by the third highest forecast, finishing +0.3, and Dmillz25 with +0.5 had high score. 

 

UPDATED TABLE OF EXTREME FORECASTS (wins and losses)

<<< ---=--- 2017 Annual Scoring Summary (Jan-Apr) ---=--- >>>

... ... ... ... ... ... ... (see post 22 for April 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, RJay had best scores for NYC, BOS and ORD (in April) and also for the eastern and central totals in April, and is high score for April. There are sometimes ties so the totals may add up higher than the number of months. Meanwhile, best total scores Jan-Apr are highlighted in red in the table for six locations, and in bold italic for two groups and for all six.

All scoring has been updated except for DCA as they are late reporting a final anomaly. My provisional of +7.0 is not likely to change much, and as that's outside our forecast range, the scores won't change except slightly for anyone above +1.8, so check back but don't expect more than a ripple of 1-2 point changes here and there. 

(edit May 2nd) _ The tables were upgraded to final as DCA just reported in with +7.0 (CLM document confirms this). Snowfall contest was recently updated in the March thread, and a final report will appear in the May thread.
