January 2020 Boards weather forecast contest -- new participants welcome

Welcome to the 2020 forecast contest ... we may get a few more entries but for now, this is the table of entries received. As noted in the original post, late penalties are cut in half for this month only. Even if you were to read this mid-day Thursday and enter, you would only be looking at a six point deduction instead of the normal 12 (at 1500h, after that, penalties will increase 1 point per hour). Welcome to esposito and WesternStorm, hope we do get some more new (to our contest) forecasters. For their benefit, I will mention that the table of entries runs from highest to lowest IMT predictions and where tied, from high MAX to lower MAX values, if still tied, same idea for MIN etc. Consensus is based on a median rather than a mean of the entries so that a few wildly different values don't have as much effect. Con Sensus has always been about a top five performer in our contests, rather hard for the math to be much different. Scoring is based on the following general concepts:

IMT max of 25, deduct 1 pt per 0.1 error
MAX and MIN score 20, deduct 1 pt per 0.1 error
PRC scores 15, deduct 1 pt per 3% error
SUN scores 10, deduct 1 pt per 5% error (rounded off, so within 2 scores 10, within 3-7 scores 9 etc)
BONUS question usually scores 10 and sometimes a point or two extra if you get very close to the right answer(s).

When regular scoring will be too low, scores revert to "minimum progression" which awards points on a rank-ordered scale from 1 under max to zero. There can be modified minimum progression if one forecaster's raw score is within 2 of the max, then the rest of the scores can only be boosted half as much from raw to progression so that the one accurate forecast is better rewarded relatively speaking. No minimum progression score will be lower than a raw score, sometimes a blend is the fair solution.

______________________________________________-

The general consensus appears to be rather mild and near average for rain and sunshine, with a lack of apprehension for strong winds (only three of us went as high as 75 knots). Later entries will be added and Con Sensus may change as a result.

Just a heads up also, if anyone is following this month's thread and didn't notice, I posted historical scoring records from the entire decade in the December thread. Will be adding a few things to that going forward.
