Winter '16 / '17 - Snow Storm #1: Near Miss

ACY Boardwalk (1928)
The season/s first snow storm out-performed not only the numerical models but the professional meteorologists responsible for issuing the official forecasts.

Heaviest significant snowfall (>= 4") at first-order reporting stations was observed along and either side of a line from CON - BOS - BDR - BDL - ORH - CON.  In addition to these five forecast points ... PWM at 3.6" and CAR at 3.5" ended up being close enough to have warranted a 'call for forecasts' and a contest-worthy snow storm had the writing been on the wall Thursday evening.  As it was ... NE snowstorm legend Paul Kocin painted a large swath of 40% probability for at least 4" on WPC/s afternoon package.

Models were late catching on to this storm/s potential.  Similar circumstances plagued last year/s contests ... as well.

Winter '15 / '16 Regular Season Snowfall Contest Note

Great Blizzard of 1888 - Wilmington ... DE
Market St looking N from 10th St
17th Annual 'Regular Season'
---
No FINAL standings
Two contest-worthy storms were too few for a valid contest.

Under the 'two-thirds' rule;
Forecasters are included in end-of-season rankings
if they entered at least two-thirds of all storm contests.


Given only two contest-worthy storms during the season ... forecasters with one entry only would not have been eligible.

In the interest of fairness; forecasters should have at least three opportunities to enter ... so three storms seems like the bare minimum to make certain a valid contest.
