Typhoon Tip Posted December 17, 2018 Share Posted December 17, 2018 Mm... my immediate impression is that the models that upped the QPF will be right ... but this system is just got a warm layer (whether surface or intervening aloft) that was not as well handled by the colder ones. So,... cold rain wins for the larger chunk of the area. 2 1 Link to comment Share on other sites More sharing options...

I wonder what model they use Here you go .NEAR TERM /THROUGH MONDAY/... 730 PM Update... Band of intense precipitation is not moving onshore in southern NH and will eventually lift into coastal Maine tonight. Water vapor imagery shows a large area of cooling cloud tops moving into southern New Hampshire. The band of frontogenetically forced precipitation is moving quickly and have opted to move the advisory time up for southeastern NH and southern Maine to 10 PM as opposed to midnight. By then accumulations will have already started. Dew points in the mid to upper 20s leave room for wet bulb cooling, and although many spots may start out as rain they will change to a wintry mix or snow. Merrimack and Belknap were also added to the advisory. After retooling the PoPs and snowfall amounts to match a blend of the latest HRRR/RAP13/ NamNest...more than half of these counties may receive 3" of snow with a trace of ice.
