16th _ Went a day late as NWS had not updated all CF6 on 15th, BOS and DEN still not updated so used daily climate reports to estimate. The forecasts to 14th were not out as much as 15th data might imply (DCA to BOS, ORD, DEN) because 15th was very warm, still, they were low by about a degree; the rest were fairly accurate. ... Have now projected to 22nd and end of month, the GFS continues quite warm in all regions 23rd to 30th. Month will likely end quite a bit warmer than forecast range for central and DEN. Seasonal max had no new developments despite 98F at DCA on 12th, the table back in August thread is likely final now, will confirm around 25th.

23rd _ Some of the stations have not updated since the 8th so I had to estimate their anomalies so far. Since the seven-day NWS forecast takes us to the 29th, I have added day 8 from the GFS to the one forecast added today although most of the NWS forecasts I used had updated through Monday 30th (I am a bit late getting to this today). This will make it possible to post provisional scoring by tomorrow.

1st Oct _ Final anomalies are now posted, and scoring will be adjusted very soon as most of the estimates proved to be correct..

Final scoring for September, 2019

 

Scoring is based on provisional anomalies in previous post. 

* one point late deduction included

^ scores based on max-60 rule _ 

__ the progression used was 60, 53, 46, 39, 32, 25, 18, 11, 4 setting normal between levels or at zero if lower than all.

__ this was modified to a more equitable progression for ORD and ATL where most of the raw scores were lower than 30.

__ the progression used for those two locations was 60, 55, 50 etc.

Extreme forecasts

DCA __ +5.5 is warmer than all forecasts, Roger Smith (+2.4) has a win.

NYC __ +2.4 is warmer than all forecasts, Roger Smith (+2.0) has a win.

BOS __ +3.1 is closest to the warmest forecast (Roger Smith +3.3) for another win.

ORD, ATL, IAH and DEN are all likely to finish well above all forecasts. Roger Smith has a win for ORD, wxallannj for ATL and RodneyS has two for IAH, DEN.

PHX __ +0.7 is lower than all forecasts. Due to late penalty, BKViking (+0.9) has a "no decision" while Scotty Lightning (+1.0) has high score and the win.

SEA __ As the outcome is +1.5, Tom has second coldest forecast and high score for a win. Scotty L has a loss. Normal also gets a win.

Scoring has been completely updated now. 

FYI, BKV would have one point less than second place DonS without any late penalties (175 points in total). Tom is down 31 on one set of late penalties, but would remain a bit behind Scotty L. Wxdude64 has only lost nine points, but that would move him ahead of me into third (fourth counting BKV who has one more point than wxdude64 when late penalties are added). As I mentioned in a previous post, I don't really think BKV has lost quite that much ground as the later forecasts may have gained insight (which is why we have late penalties more than as a punitive measure). In the two months where BKV took significant numbers of points, he did manage to finish middle of the pack and had some high scores (best forecasts) at least on raw scores. If you assume that half the lost points would have remained lost with less insight, then adding 80 would get BKV closer to the chase pack but no further ahead (his total is now 128 behind hudsonvalley21). The chase pack has five within about 50 points, but RodneyS retains a lead of 237 over DonSutherland1. I worked out that over three months remaining in this year's contest, you can gain 216 points by being 0.4 F closer on each location.

=============================================================================

Congrats to wxallannj for a winning total of 14 deg just ahead of RodneyS at 15, with hudsonvalley21 and DonSutherland1 tied third at 17.

The best performances in regions were:

_ Eastern (DCA, NYC, BOS) __ best score RodneyS (5 deg) __ second place wxallannj, BKViking, DonSutherland, Tom (all 6 deg)

_ Central (ORD, ATL, IAH) ___ best score RodneyS (3 deg) ___ second place Don Sutherland and Scotty Lightning (both 4 deg)

_ Western (DEN, PHX, SEA) _ best score wxallannj (2 deg) __ second place hudsonvalley21 (3 deg) __ third wxdude64, BKV (4 deg)

 

The most perfect forecasts went to RodneyS with two. 

Our consensus forecasts would have scored 16 points, good for third place. We were generally a bit too high for NYC and ORD, otherwise quite close as a group to the other seven.

Given the number of hot days, it's perhaps somewhat surprising that the outcomes were all rather close to seasonal normals, but perhaps that was due to high humidity which can make it difficult for readings to get much past 100 degrees (apart from PHX which also had a rather average outcome despite a lot of sustained heat waves). 

The next special contest will be seasonal snowfall and that will be introduced in the November thread.
