So far this year, 30 locations out of 45 have qualified, 4 in Jan, 5 in Feb, 7 in March, 6 in April and 8 in May. Of those, 16 were awarded to warmest forecasts, 14 to coldest. A loss in the standings represents a case where second most extreme forecast had the high score and the win for that month. Normal can only win along with a forecaster. There have been two shared wins (one by three) accounting for the 33 total wins (excl Normal).

Final scoring for May 2021 The NWS has changed reporting to the 1991-2020 normals but as the contest specified 1981-2010 normals for this contest month, the anomalies reported will be adjusted (all but PHX will be adjusted up since 1981-2010 values are cooler than 1991-2020, PHX actually went down 0.1 from May 1981-2010 to May 1991-2020, not a very significant change). Small late penalties are shown as * per point lost. Total in brackets is before accumulated late penalties. A verification was made to ensure that CF6 reports were using 1991-2020 normals. DEN worked out to a value 0.2 below the 1991-2020 normal and 0.3 above the 1981-2010 normal. All eight other locations worked out to values identical to the 1991-2020 normal. The DEN anomaly may be either (a) a manual error or (b) a rounding issue within max and min. In any case it makes no difference to the outcome, I decided to take their reported actual value and the differential from 1981-2010 which worked out to a contest anomaly of --1.0 (would have been -0.8 had the same rounding issues been applied). As our lowest forecast was -0.6, the differential in scoring would have been the same.

(Normal also scores a win). _ NYC _ RodneyS wins with lowest forecast. _BOS _ RJay wins with highest forecast. _ORD _ For 1981-2010 anomalies highest scores were near our consensus (for 1991-2020 coldest forecast would win). _ATL _ RodneyS wins with lowest forecast. _IAH _ wxallannj wins with lowest forecast. _DEN _ wxallannj wins with lowest forecast. _PHX _ DonSutherland1 (second lowest forecast) has a win, RodneyS a loss (lowest forecast). _SEA _ Tom, BKViking and Roger Smith would share a win at +0.8 or higher. ============================================== How scores would vary with 1991-2020 normals used to score instead DCA, NYC, ATL, IAH, DEN would all be lower scores (anomalies further below all forecasts). BOS would all be higher scores (not as much warmer than all forecasts). -- nobody at any disadvantage in these cases. The net gain is 64 points vs using 1991-2020 (for these five). ORD had a higher differential in normal values than other locations. And it fell right into the middle of the forecasts. Those four with forecasts above +1.1 have a higher score by 30. Those between --0.4 and +1.1 have more similar scores which changed up or down by smaller amounts. The lowest forecast from wxallannj (--0.5) lost thirty points relative to score for 1991-2020 (98). RodneyS ended up 18 points lower. Most of the others gained slightly (but not the 30 points gained by warmer forecasts). So only two scores were really impacted significantly with a few smaller adjustments all of them a disadvantage to some extent. PHX only changed by 0.1 and in the downward direction unlike almost other changes in the normals. That means that the scores are all 2 points higher than they would be for 1991-2020, except for DonS and RodneyS who would score two higher with 1991-2020. SEA would come out in almost the opposite order, the new normal is +1.5 higher and the forecasts were generally between the anomalies that were generated by the two different values. The largest differentials are around 30 points. Wxallannj who up until this forecast was running at a disadvantage did relatively well by the change so that overall we reach a situation where using either normal would make only small and limited differences overall for scoring. ============================================== The annual scoring report will be along later today I hope, with an update on the "four seasons" scoring.

Just to confirm, Ana and any other named storms that occur before you post are in the final result for the contest which is simply this year's count (which people were nice enough not to comment, but I had it backwards in post one, it's named storms, canes, majors, but as everyone knows that probably didn't notice my mangling of the order). My guess is going to be 23/13/7 and there is no reasoning because I simply know this to be a fact (until proven otherwise).

I have posted a full report on the 1991-2020 normals in the June thread, and they apparently are already replacing the 1981-2010 in NWS reporting, I believe ... (from the June thread ...) By the looks of the SEA current reporting, they have already switched to 1991-2020, the anomaly for 56.3 is reported as -0.8 which says that the "normal" for 1-26 is 57.1, comparing that to 1981-2010 and 1991-2020 it would appear that the report is relative to 1991-2020. Will discuss this with you all by private message and see what you think should happen for May, but for June we will take the reports using 1991-2020 so it's up to you to assess the new normals at the nine locations, hope you find the above tables useful in that regard. Some locations have warmed more than others (not only climate change at work but also urbanization issues).

Here are May and June normals for both intervals, the May data will be used to determine what reporting is in place for the May contest and the scoring will be based on an adjustment to 1981-2010 if necessary since all contest entrants agreed that they were providing forecasts relative to 1981-2010. I have added all the monthly normals for both intervals.

Update: I am reading press releases stating that the 1991-2020 normals will be in use perhaps even this month (May) so I assume they will be used for the June CF6 products that are used to score the forecasts. Hold off on posting until I can get a list of 1981-2010 and 1991-2020 normal values for the nine locations, to see if some stations have significant differences.

Predict the temperature anomalies for the usual nine locations ... check back closer to the deadline for any updates as I try to find out if the NWS plans to change to 1991-2020 normals for June. For now, will assume entries are relative to 1981-2010. Will score them as such unless otherwise tagged, if I can establish the differentials. Also due to the timing of Memorial Day weekend, probably will not start charging late penalties until June 2nd, if you don't see a table of forecasts you can edit on June 1st without penalty.

The projections above are based on the following: (days 1-10) continued rather cold in the east but this regime spreading further south to include ATL and IAH in below normal northeast wind patterns, west warming esp valid SEA and DEN, then days 11 to 16 and beyond for a month end projection just took normal values in east expecting a warming trend beyond the model run, and a +2.0 anomaly for western locations days 11-20. 23rd _ Back to warmer weather after mid-month, some of the anomaly projections were not quite as far off as they look because of the difference in update time (to 22nd) and projection (to 20th), but a warmer look now to end of month in most cases, will result in warmer end of month projections. 30th _ The most recent projections have been thrown into disarray by the huge negative anomalies on the backside of the east coast low, and the introduction of 1991-2020 normals which are higher (as discussed below) therefore the reported anomalies are lower by that much also. Will be working out what the anomalies should be for the contest since you all made forecasts based on 1981-2010 normals for May. As I've been saying we will go with the reported anomalies relative to 1991-2020 from June onward. For now, the numbers I am using to start the provisional scoring process are my estimates of what the contest anomalies will be, the 1991-2020 anomalies will be lower by various amounts. See the June thread for more details. (11th, 23rd) _ Checked for snow at contest sites, just a trace at DEN on 10th. Probably not quite time to call the contest yet (latest updates are in the April contest thread).

It's no longer Greek to me, the simplified format makes scoring easy, especially if everyone scores zero. Hopefully we won't have a repeat of the astronomical distorted season last year, last time I checked, 59/8/-2. So this year once again just predict the count at the end of the year, Majors, all canes, all named storms (e.g. 18/10/5). We'll say June 10 for a deadline, may extend it if the season is slow to get going and/or entries have fallen short of a good number. Edit your entries without notice before June 10, won't be making any notes although I will read them.

So far this year, 22 locations out of 36 have qualified, 4 in Jan, 5 in Feb, 7 in March and 6 in April. Of those, 14 were awarded to warmest forecasts, 8 to coldest. A loss in the standings represents a case where second most extreme forecast had the high score and the win for that month. Normal can only win along with a forecaster.

Predict the temperature anomalies for these nine locations: DCA _ NYC _ BOS ___ ORD _ ATL _ IAH ___ DEN _ PHX _ SEA As far as I know the anomalies in use will continue to be 1981-2010. If this changes before the deadline I will get in touch with entrants. If it changes during the month with 1991-2020 to be used at end of month, I will try to find the differentials to apply and unless otherwise notified your forecasts will be assumed to be with reference to 1981-2010 normals. We will do the seasonal max forecasts this summer but I'll add that to June this year.

Winter Snowfall contest 2020-2021 -- Table of entries and scoring _ updated for April snowfalls (at DTW, BUF, DEN, BTV). The red highlighted numbers are best forecasts at this stage, and those underlined are settled as such because all forecasts have already been passed or for ORD the max forecast is closer than the others although not yet passed. BOS is tied for best forecasts on either side (37.0, actual 38.5, 40.0). (Apr 23 update _ DEN added 12.6" BUF, DTW and BTV 3-5" amounts since last report, as shown. ) Note _ for current total departure, the first number is your total error at this point. The second value in brackets is the total of "non-reducible errors" for those stations that have passed your forecast. Your total departure can improve if more snow falls at stations where your forecast is higher than current values. It can only be increased by snow falling where your forecasts are now passed. All of us have been passed at NYC, DEN and SEA. All but one have been passed at ORD. Nobody has been passed yet at BTV (contest leader RJay would be first and has 1.9" to spare). Two forecasters have some left to use up at DTW, and BUF has only passed contest leader RJay and current third place wxallannj.

The same is true of ORD since only Scotty Lightning can gain any ground and that would be a net of 3.0" before he also joins the rest of the field. The main potential for change would be snow at DTW which would assist third place wxallannj and hudsonvalley21, but they only have 2.1" and 3.3" to use, their net gain can be twice those amounts, meaning that both could pass wxdude64 but not RJay. (at around 2.6" hudsonvalley would pass wxallannj). More snow at BUF could give wxdude64 back his advantage over wxallannj but hudsonvalley21 would keep pace. It would take a fairly large dump of snow at BUF to overtake RJay who is already passed there. Unless that happens I think the contest is fairly well settled now.

It would only be the last two maps in play for our contest implications, and those are annual averages, various months at various locations may show odd variations -- I expect most of the 1991-2020 normals to be in the range of 0.5 to 1.0 F deg higher than the ones we have been using, whether that's going to be significant to our estimates is probably near the edge of our presumed tolerances anyway. If it's possible I will post the differentials for each location with each monthly announcement once I know that the NWS will be giving us anomalies in the new time frame. Haven't heard anything new, still on the lookout for that info (Don seemed to think it could be June). In other news, I have updated the anomaly tracker (two posts back) and found some extra snow for the contest sites in recent days, so that table will come over here from March in an updated form soon. Provisional scoring will follow. I have a feeling our consensus was pretty close. My cold came a little too late to tip the scales.

No new snow at any of the contest sites so that report stays over in March for now. (note BOS anom estimated, 4.1 to 13th, +1 for 14th not added to CF6 report yet). 23rd _ A day late getting to the verification which is probably better than it looks because anomalies were changing fairly quickly in past two days. The projection to end of month is based on the idea that warm anomalies will outweigh cold by 2:1 as different sectors move through, so that the downward slide currently going on may continue for a couple more days then a reversal to much warmer temperatures will occur in the east, while DEN and IAH will get into very warm air soon and then turn a bit cooler. Except for DEN there have not been large changes in these projections since last week's effort. (note: these changes will need to be made to snowfall contest amounts _ DTW +3.6" (44.9") BUF +4.9" (77.0") BTV +3.5" (63.1") DEN +12.6" (80.2") The snowfall contest post in March will be updated and moved into this thread later today. 1st _ Posting final anomalies and adjusting scoring. Some final anomalies are close estimates based on 29th CF6 and 30th climate report. I am also checking against Apr 2020 CF6 to verify that normal values derived from anomalies quoted are same (i.e., 1981-2010). So far these are verified results: DCA same (both 56.8) NYC was -0.1 diff, 53.0 this year, 53.1 last year, BOS same (both 48.1) ORD was -0.1 diff, 48.9 this year, 49.0 last year (could be a rounding with NYC,ORD, or new normal is almost same as old one, in any case not significant to scoring really) ATL same (both 62.0) IAH same (both 69.5) DEN was -0.1 diff, 47.4 this year, 47.5 last year PHX same (both 72.7) SEA same (both 50.3) __ I think the 0.1 differences may be second decimal rounding results, these are obviously same normal sets as used a year ago. For example, let's say a month ends 59.23 and normal is 59.37, then the difference is -0.14 or -0.1 although from rounded values it would be -0.2. So I have convinced myself that we are still using 1981-2010 normal values for this month. __ all updated now __ scoring also updated (being double checked)

In the net-weather thread I have recently edited in these new data and a few corrections: (a) March 2021 at 45.8 F (7.67 C) was t13 warmest with 1995, and Toronto (4.0 C) was t9 with 2020. (b) March 2021 at 3.41" was t60th driest with 1879. The trace of snowfall is tied with seventeen other years ranked t-4th. Only 1878, 1903 and 2012 recorded zero (no traces) snowfalls in March. (c) A new daily record of 82 F was set on March 26, 2021 (replaced 76 1922). (d) New high mins were set or tied on March 11th (52 broke 48 1898) and 26th (52 tied 1986). (e) An error was found in the max daily temps, Oct 15 should read 1956 rather than 1930 (84 F was okay). (f) The 65 F record for Dec 28 was later tied in 2008. (g) The 60 F record on Jan 24, 1967 was not color coded. Some of these additions or errors can be adjusted if you downloaded the excel file. The corrections and additions will appear in the next instalment due around June 2, 2021. I am working on a log of record and notable daily highs, which tracks the evolution of the final set through a set of "starter records" for 1869 to 1900, adjustments to 1930 (about half the starters are broken in that interval), then any other new records in chronological order to the eventual record high (if not already set), then any notable close calls and a complete log of warmest days in the recent past (1991-2021 incl). This is about three-quarters finished and is the reason why I found the errors noted above. Hopefully this work will establish that all the listed records are correct. I plan to do the same for record lows where the starter records are going to do a lot better in terms of surviving later challenges. If you downloaded the Toronto file, there was just one error found since then, a ranking error, the details are in the net-weather thread.

So far this year, 16 locations out of 27 have qualified, 4 in Jan, 5 in Feb and 7 in March. Of those, ten were awarded to warmest forecasts, six to coldest. A loss in the standings represents a case where second most extreme forecast had the high score and the win for that month. Normal can only win along with a forecaster. There has been one shared win accounting for the 17 total wins (excl Normal).

For slightly larger late penalties on Tom, raw scores in orange, adjusted below in regular type. ORD was scored by "max 60" rule but ATL ended up with a raw score of 72 so by the rules it was scored by raw scores for all forecasts. The scores marked with ^ symbol are adjusted up from raw scores to progression (60, 54, 48 etc). Late penalties reduced some by 1 pts.

DCA had a tie between so_whats_happening and wxdude64 who both predicted +3.1 (final +4.4). NYC and BOS both go to RJay with +2.5 forecasts (NYC prov +3.5, BOS final +3.7). ORD heads to DonSutherland1 (+3.0) (actual +6.3) and ATL to so_whats_happening with +3.2 (actual +4.8). DEN will be a win for wxdude64 (-2.2) as well as Normal (actual -1.0). PHX will be a win for DonSutherland1 with +0.3 as well as Normal, with outcome -1.1. IAH (+1.7) and SEA (-0.9) are out of the running with consensus closer than the extreme forecasts. So in total that's two wins each for Normal, RJay, DonSutherland1, wxdude64 and and so_whats_happening. ______________________________________________ Annual update has been posted and is now also confirmed. Looks very competitive after March. We had a tie for scoring lead in March, congrats to wxdude64 and so_whats_happening who overcame slight late penalties; Tom actually had a higher score before his somewhat larger late penalty reduced the outcome to fourth place.
