oops, missed one.

(and there's something wrong with the consensus sum of squares)

Right you are abt CONSENSUS
Don't know what I'd do w/out your eagle eye.

Root cause: formula didn't copy down all the way.
FIX on the morrow.

TQ said...

DOH! Lost your entry too!
OMG ... so sorry RS.
Working on fix now.

TQ said...

Should be good to go.
If not ... just shoot me.

No worries, I like to document my failures. ;)

As for consensus, pretty difficult for it to finish last in anything, that would make an interesting math problem.

I can do it with ease however.

and thanks for the contest, we all enjoy it, strange sort of a season in some ways, and it may not even be over (well this part is).

As you well know ... running a contest is a labor of love. Thankful for the continued interest and support from the Forecasters.

Yep, this is a great website, hope it attracts even more forecasters in the coming years. Also I hope it snows where I predict snow, that would help.

Congrats to Don Sutherland for a solid forecast and season. He is also leading a contest that I have running on American Weather forums (our season only ends when DEN stops snowing although it barely started this winter). If you like this sort of thing, look in the February contest thread for the snowfall contest updates. Also have one running in the Great Lakes / Ohio valley forum on American weather.
