Old news, but I took at look at some of the output from the 6UT GFS for BWI. 

 

According to this simulation, 

Snow begins Friday morning at 9 AM and ends Saturday afternoon at 1 PM.

Temperatures range from 26 to 29 degrees 

1000-500 hPa thicknesses peak at 541 and 850 hPa T peak at -2 C late Friday evening. 

Winds strengthen throughout Friday and approach blizzard levels  (34 mph late Friday evening) .

Wind direction E to NE to N

Total precipitation 2.07".

over 300 posts for me to catch up on, so forgive me in this information has been posted already.

 

Cobb Output for Westminster

00z GFS: 1/22 18z to 1/24 06z 3.48 QPF (mostly snow, one 3hr period where temp was just above 32, so Cobb has it as RASN)

 

06z GFS: 1/22 15z to 1/23 18z 2.27 QPF (all snow)

 

 

can't complain about that! Now to catch up on the thread. 

12 inches of snow over one three hour period is just WOW.
