General model consensus along with radar trends indicates snow may move into the area a little faster, likely beginning around 1am in Keene, and peaking between 5am and 7am. An inch could be on the ground by 4am, with another 1 to 2.5 inches between 4am and 7am. Light snow will continue through mid morning, with another 1 to 1.5 inches likely, then change to sleet and light freezing rain before ending by 2pm. No ice accretion is expected. Total of 3 to 5 still looks right.

Friday and Monday still look very good. Between the GFS and ECMWF combo (12z Euro looks amazing by the way), I have good confidence in 6+" accumulations with both storms. Details will be posted later tonight.
