Winter '09 / '10 - Strike 2


Second contest-worthy storm in less than a week to be poorly forecast with enough lead-time to make a call for forecasts.

Early NWP forecasts indicating three-to-four hour snow burst followed by change-over to rain were way underdone.  HPC/s winter weather products also failed to indicate a decent event was coming for New England until it was too late.


ALB:  7.3" between 0836z and 1551z  (~7.5 hrs)  New daily record.
BGM:  6.4" between 0553z and 1216z  (~6 hours)  New daily record.

BDL:  6" between 0906z and 1251z  (4 hours)
ORH:  7.5" between 0933z and 1503z  (4.5 hours)

CON:  8.3" between 1117z and 1848z  (7.5 hours)
PWM:  4.3" between 1248z and 1839z  (6 hours)
BGR:  4" between 1534z to post time  (7 hours and counting; 8 - 12" forecast)
CARL  6 - 10" forecast

At least three other forecast stations measured nuisance snowfall amounts.
