November 2017 temperature forecast contest and winter snowfall contest (with added locations)


Recommended Posts

First of all, the routine business ... predict the temperature anomalies in F deg (relative to 1981-2010 normals) for these nine locations:

DCA __ NYC __ BOS _____ ORD __ ATL __ IAH ____ DEN __ PHX __ SEA

The deadline for this ongoing contest is 06z on Wed Nov 1st with 1% late penalties for each 2h first 36h, then 1% per hour.

Snowfall contest -- improved over previous years by deleting ATL, IAH and PHX and adding three places where it actually snows :)

So predict the total 2017-18 winter snowfall (including anything already measured) at these nine locations:

DCA __ NYC __ BOS _____ ORD __ DTW __ BUF ____ DEN __ SEA __ BTV

You can submit entries for this up to and including November 15th. Also you can edit entries already made, as I won't collect your forecasts for a table of entries until Nov 16th after the deadline of 06z. This does not apply to the temperature forecasts, those were collected and stored several days after the deadline of Nov 1st. 

Good luck and thanks to ATL, IAH and PHX for giving up their spots for future considerations. (now watch it snow like crazy in the south)

(just reminding all participants you have to end of Nov 15 to submit or edit snowfall contest forecasts, check post 1 for the locations, we're not bothering with the southern three this winter)

Color codes:

+4.0 __ warmest forecasts (regular entrants)

--2.0 __ coldest forecasts (regular entrants) __ where positive (ATL,IAH), Normal has coldest value.

+8.0 __ more extreme forecasts from other entrant(s).

____________________________________________________________

Consensus is determined from the regular entrants (so that at end of year, it is comparable to total scores in the regular group) and in this case (to date) this is the median of 14 forecasts (2nd to 15th listed in the table of forecasts) and thus is the mean of 7th and 8th ranked values. This will be adjusted if Damage makes an appearance (Stebo has bowed out for the year, see his post above). This was not quite a precise operation over the year as I probably included occasional entrants Jan to Apr before having this brainstorm of making consensus fully comparable (in other words, giving us all a chance to outdo our own internal consensus). Last month, for example, it probably reduced the Consensus score from 400 to about 350. I think this is a better comparison for the regular entrants.

SnoSki14 (and rainsucks if you enter later) may catch up to me or other stragglers in the annual contest at the rate achieved so far, and you will gradually enter into regular forecaster territory if you stay with us, the first occasion would be winter 2017-18 seasonal scoring where all who enter three months are eligible, and of course the 2018 contest year

(note: Nov 11th, temp forecasts verified and placed in excel file, edits only allowed for snowfall contest which closes end of Nov 15th).

Here's our first look at the anomalies and projections ... expect the eastern values to drop sharply after today with record low readings reported (Central Park broke a record for Nov 11th from 1933 which came before some notable record lows in late Dec 1933 and through Feb of 1934).

Thanks Don, and just a reminder to all entrants or lurkers who would like to enter this snowfall contest, the deadline will be whenever I come into the thread on the 16th to create the table of entries, so let's say 16th 06z to be safe. Anyone can edit their current entries without making a note of it, before then, as I have not marked anything down yet. Good luck. I just added my entries to my original post. Expecting a fairly snowy winter in the Pac NW and closer to normal most other locations, thinking the winter will have some good periods but it may be a dry cold when it gets cold.

There is also a snowfall contest in the Lakes/OV forum (deadline end of Nov) and off-site some of you already know about this one, the Northeast U.S. snowfall contest blog at the location indicated below, seasonal forecasts there are due Nov 30th and then they also have storm forecast contests through the season.

Not late, the deadline is tonight. Anyone can edit their entries for the rest of the day, I will be collecting the forecasts into a table of entries around 06z to 07z which is still before midnight where I live, but most of you might want to have a look in the morning to see the spread of snowfall predictions.

Extreme Forecasts

 

DCA __ win for Tom (+1.1) and Normal, "no decision" for SD (+1.0) due to 7% score reduction

NYC __ win for Tom (+0.8) and Normal

BOS __ win for Tom (+0.2) and Normal.

ORD __ no longer qualifies as an extreme forecast, third lowest forecast was high score.

ATL __ high score around consensus, does not qualify.

IAH __ at +4.9 is a win for RodneyS (+5.4), loss for DonSutherland.1 (+5.7)

DEN __ win for wxallannj (+2.5) 

PHX __ win for RodneyS (+2.8)

SEA __ win for wxdude64 (+1.1)

I have finished moving and posted final anomalies (several posts back) ... will be hooked up on home net late 4th, finish scoring then.

In the above, all will gain 4 pts DCA,2 pts NYC, 2 pts IAH, and most 8 for ORD (some colder fx will lose 8 there). All will lose 4 BOS and 6 SEA (wxdude64 only loses 2 there). ATL points change by 4 (based on 2.0, actual 2.2). Will have to check back on adjustmentts to all-low-scoring DEN, PHX, these scores may not change much.

All other updates to come. Scoring order not likely to change much).
