Due to timing constraints, have opted to follow NWS forecast product closely this update concerning the Clipper System and trailing lake effect snows, with only some minor tweaks.
Concerning the Clipper... per latest radar, first batch of precip about to make its way offshore with many areas reporting light snow with upwards of a coating as this moved thru, with rain mixing in aross the immediate coast. Final batch of precip is now entering western PA and will move thru during the overnight, producing another coating to an inch in most places from western PA to the coastal plain. One other noticeable area of snow was across the western half of upstate NY, where light to moderate snow was falling. Expecting widespread trace-1" in this area, with up to 2" in the heavier bands. This batch of precip is progged to continue off to the east-northeast into western New England during the overnight hours.
Other concern is across the eastern half of Maine, where latest radar showing some enhanced banding activity affecting the area. Have followed closely with NWS forecast, and issued a swath of 3-7" across this area...with heaviest accumulations of up to 7" across the far east on the Canadian border and lesser amounts of around 3" along the coastline.
Concerning lake effect potential: Have also stayed close to NWS forecast on this potential, with heaviest snows southeast of Lake Erie. Do to expected short duration of the event, total snowfall totals look to remain below the 12" mark, with mostly advisory level accumulations. Off lake Ontario... this looks to be a solid advisory event here as well, with highest totals across the Tug Hill where up to 7" is possible. Elsewhere across north central NY, a general 2-5" looks to be a good bet.
Behind frontal passage on Sunday...bitterly cold temperatures look to be on tap for overnight Sunday into Monday. It will be blustery with lows ranging from the teens and 20's across along the coast, to single digits inland. Wind chills will approach advisory criteria overnight Sunday into Monday morning across the interior northeast, especially interior New England and northern NY.
Next Week: Cold spell will be short-lived however as next system approaches region from the southwest on Tuesday bringing mixed precip and rain to much of the northern Mid-Atlantic and Northeast before changing to all rain by Wednesday. Behind this system, there remains quite a bit of uncertainty with regards to a possible coastal storm to impact atleast a portion of the area by the end of the workweek. At any rate, upcoming week looks to be quite active. Will be taking a closer look at mid-week storm with next update.
