2026 forecast contest thread -- call for Jan 2026 forecasts

[Roger Smith]

With the new year approaching, I am terminating the 2025 contest thread with the results of Dec 2025 and the annual contest, and moving all new activity over to this thread where you can post Jan 2026 forecasts at any time, as is our custom in January, no late penalties will fall until later into the first week, let's say for sure no penalties before end of Jan 2nd, so take your time and post / edit freely -- if you don't see a table of forecasts you can edit because I only see the forecasts when I make up the table.

For anyone new wanting to enter, the forecast contest asks you to predict temperature anomalies at nine locations across the U.S., in F deg relative to 1991-2020 averages.

The nine locations are DCA _ NYC _ BOS _ ORD _ ATL _ IAH _ DEN _ PHX _ SEA

... Happy new year ...

Glad to see all of you wanting to continue, will perhaps send invites to some part-time participants of recent times too.

You can edit any of those forecasts up until afternoon of Jan 2nd when I start working on a table of forecasts. 

A lot of the scoring work for last year's contest has been done, just adjusting a few numbers as final data reports come in. ORD was -3.5 with a +14.3 week 22nd to 28th. Now that's bizarre.

tossing some numbers out: hopefully not too late! I keep saying I’ll be consistent but maybe for real this time!
