Thanks, RJay, as a friend of the contest in many ways, and in view of extenuating circumstances which you explained to me privately, I am going to post your forecast with just a small time penalty that would protect the field given that you had a bit of extra information by posting time. But I won't apply the entire penalty. As I mentioned, anyone else who (in coming months) has more pressing concerns at forecast time should feel free to seek a partial waiver on late penalties. I am just going to say -x% for now and see what I think is fair after assessing a few things that aren't in my head right now, such as trends in modelling since 1st, and differential from consensus in the forecast submitted. Anyone who would like to offer an opinion on this, would prefer in private message.

Final anomalies _________--1.5_--2.7 _--3.5 __ --0.6 _--0.4 _+1.3 __ --1.2 _+1.5 _ +2.0

 

(8th) _ The trends in the coming week appear fairly cold relative to normal, and this remains the case to some extent in the longer range although departures do not look very great. Quite a few of the locations are slowly trending towards a near normal overall outcome after this faintly warm start, more or less the afterglow of the warm March we just finished. 

(15th) _ This past week saw a slight drop in the earlier anomalies, one very warm day on Monday 13th in the east prevented a larger slide there. It continues to look rather cold in eastern and central regions both this coming week and later in the month. Will stay with the original idea for the 24th as end of month anomaly projection with slight changes. The snowfall contest has been updated in the March thread. Around the end of the month I will move the post over here, contest runs until Denver stops snowing which is often mid-May. It can still affect the outcome of this contest.

(22nd) _ Anomalies have dropped to near or even below zero in some cases, but the coming week looks a bit closer to average, and I have only adjusted the earlier end of month projections slightly. Will perhaps post some preliminary scoring soon.

(29th) _ Warmth in western regions has reversed some anomalies there, but east locked into rather cold weather for a while yet. 

(May 1st) _ Posting final anomalies overnight and updating the scoring below. All are now confirmed. Scoring is more or less complete (just checking some updated totals). 

[bkviking]

Man I blew this month big time. 
you and Don S we’re onto something. I just expected the blocking to be temporary - we saw how that went. Now I’m v cautious about May 

[Roger Smith]

In my case, it's the broken clock syndrome. Figures that nature would waste below normal on April after that sad excuse for a winter though ...

Have decided the following on the late penalty situation. Just happy that we seem to have survived the pandemic, so will be reducing earlier issued late penalties and just tapping RJay lightly for his entry at the new max of 5%. Former late penalties will be basically cut in half with the same max. I can edit the scoring in earlier threads to reflect this (no penalties were that much bigger anyway so won't be much of an adjustment of scores already posted) ... I really wanted to go with the no penalty sentiment but then I have these pre-existing late penalties already applied, seemed a bit too lenient to say zero. But I realize that RJay made a forecast under health duress and probably without much influence from guidance. So I needed to balance all of those considerations. Moving forward, I will just set the late penalties a bit more leniently but they will be applied where necessary. The new standard will be 1% for every 8 hours late up to 2 days (8%) then 1% added per hour. 

Hope people think this is a fair solution for everyone. Scoring to follow, updating the anomalies tonight (a few posts back now). 

[Roger Smith]

Final Scoring for April 2020

BOS scores are now adjusted to the max 60 rule as top raw score was 50. The new distribution favors everyone but me so I have lodged a protest with myself which I plan to ignore.  ... Normal score was adjusted to scale and on raw score was 30. NYC also finished colder than provisional and almost went the same way but I held on to 62 points there so no adjustments. ... Hudsonvalley21 late penalties are only 1 point where applied, those are marked with an asterisk (raw score was one higher) ... RJay had a 5% late penalty assigned as explained above in previous post. That leads to a separate line of final scoring with the raw scores partially hidden in the light orange type.

Extreme forecast report 

Going cold gave your host four extreme forecast awards (DCA, NYC, BOS, and ATL) with Normal sharing the ATL award.

At ORD DonS has the high score with second coldest forecast for a win, Roger Smith takes a loss here.

IAH ended up a little closer to our consensus and won't be an extreme forecast this month. 

DEN was running as cold as -4 for quite a while then warmed up big time, so wxdude64 has a win and Roger Smith another loss. 

PHX has verified right on the money for warmest forecast (Scotty Lightning at +1.5).

SEA has warmed considerably against our expectations and that gives Brian5671 a win with warmest forecast still a half degree below the outcome.

So the summary would be 4-2 for Roger Smith on the month, and wins for Normal, DonS, SL, wxdude64 and Brian5671. 

________________________________________

Annual update follows, after revision of some penalized scoring in March. DonS has moved up several spots and RodneyS has a much smaller lead than last month, some shuffling of the deck below that. 

[Roger Smith]

< < < < < ........ <<<< ---- ====== Annual Scoring (Jan-Apr) 2020 ====== ---- >>>> .......> > > > >

Numbers in red denote highest cumulative scores for each of nine locations. Numbers in bold black type denote highest subtotals for regions. 

Some late penalties in March were reduced (because of the April decision) and a few scores were adjusted in the March scoring tables. The increases were minor (5-12 points).

It was not deemed necessary to adjust February and there were no late penalties in January.

BEST SCORES -- Totals for January to April

Forecasters are listed in same order as annual points standings. 

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.
