Consensus is the median of 11 forecasts or the 6th ranked forecast. 

Color codes show warmest and coolest forecasts, but Normal is lower for DCA, NYC, BOS, ATL and IAH and equal for ORD.

... Will move over the snowfall contest for easier reference and plenty of laffs.

__________________________________________________________

Current GFS guidance suggests temperatures somewhat closer to average than the warm start for the month, but except for the western states, anomalies will remain significantly above normal. Small negative anomalies for SEA may largely disappear in coming days but a few colder days are indicated in the outlook. FWIW, there's a major arctic outbreak coming for April 1st in the Great Lakes and northeast. 

(25th) _ Updated through the 24th and projections look very warm for the eastern and central locations, although only slightly warmer than our higher forecasts, so well done to most ... will post some provisional scores in a while. 

(1st April) _ Final anomalies are posted (as of 1230z) except for BOS which is estimated from 30th CF6 and 31st climate reports. Scoring adjustments will be ongoing until scoring post title changes to Final Scoring.

_________________________________________________________________________________________________

In a few days I will post a scoring table, to be updated (for DEN mostly) until snow stops falling (there).

It is quite unusual, I believe, for both DCA and SEA to have an essentially snowless winter, usually it would be one but not the other.

 

Current scoring for the snowfall contest

Unless shown in red, all these departures are errors on the higher side, and can be reduced if any further snowfall occurs at any locations (now only marginally possible for DEN and perhaps the inland northeast).

__________________________________________________________________________________

(Apr 1st) _ Standings are subject to change, especially if DEN picks up more snow, as the contest leader (wxallannj) will be accumulating error with additional DEN snowfall, and second place BKV has only 1.1" left before starting to do the same; third and fourth place Rodney and DonSutherland1 have some snow left to give -- Rodney can overtake the leader if 12" or more should fall at DEN.  Otherwise it would appear that a few more inches at say BTV or ORD-DTW would make no great difference to the outcome. So we await further developments at DEN. 

(Apr 15th) _ DEN has picked up 1.8" this month, BUF 0.9" and DTW 0.2" -- RodneyS now needs DEN snowfall of 10.5" although any further snow at DTW adds a bit to the task. 

(May 4th) _ ORD and DTW both added 4.7" since last report. For the three leaders, that generally meant no significant change as they had enough to absorb that addition at ORD and were already accumulating for DTW (wxallannj gained slightly as he was not quite over the limit for DTW.) The Midwest snow did move hudsonvalley21 past DonSutherland1 in the contest standings. Since DEN has added only 1.9" since last report above, given the above slight differential, that reduces the amount needed by  RodneyS now to 8.8" to catch wxallannj. RodneyS has moved to within 0.3" of second place BKV who is also now accumulating error points at DEN, so a further 0.2" would change those positions. BUF added 1.9", BOS 0.7" and BTV 0.1" -- these reduced all forecaster total errors equally.

(May 16th) _ Since the last report, DTW added 0.5" BUF 0.3" and BTV 0.1" (NYC trace !) ... these amounts leave the contest in the same situation awaiting any further snow which now is almost certain to be confined to DEN (if any falls, the current model run has no really strong indications of any). I will be posting this summary in the May thread and any further edits or comments will be found there.

Final scoring for March 2020

Scoring is based on the provisional forecasts for end of the month (two posts back).IAH will probably require a scoring boost (max 60 rule). The two lowest raw scores remain as they would be higher than the adjusted progression scores. The late penalties are shown in separate scoring lines after raw scores (in orange type) but for wxdude64, who could only drop one point, raw scores are shown with * meaning a deduction of one point. Scores in bold are high and the color codes for warmest and coldest forecasts are retained. 

Note: scoring adjusted after late penalty review for April contest. Adjustments are small (reduced late penalties).

Extreme forecasts 

DCA, NYC, ORD, ATL and IAH -- the warmest forecasts have prevailed, earning two wins for RJay (DCA, NYC) and Brian5671 (ATL, IAH) and one for DonSutherland1 (ORD). 

At PHX (-0.8) the coldest forecast has won, one more for Brian5671 (total of three this month). 

At SEA (-1.7) the high score was second coldest (RJay -1.5) so he has a win and Brian5671 (-2.0) adds a loss to the three wins.

At DEN the final value (+2.1) gives Roger Smith a win (+2.0) and RodneyS (+2.6) a loss.

BOS ended up in the middle of our range and did not qualify. 

Annual update to follow, and this table subject to adjustments as the actual values are reported.

BEST SCORES -- Totals for January to March

Forecasters are listed in same order as annual points standings. Only those who have any best scores are listed.

Ties are possible which is why some locations have more than two best scores, also, if Normal or consensus

achieve a top score, the actual forecaster with high score gets an award also.
