MD 2188 CONCERNING HEAVY SNOW FOR PORTIONS OF NORTHERN NH INTO ME
Mesoscale Discussion 2188 NWS Storm Prediction Center Norman OK 1142 AM CST Tue Dec 03 2019 Areas affected...portions of northern NH into ME Concerning...Heavy snow Valid 031742Z - 032145Z SUMMARY...Heavy snowfall with rates of 1-2 inches per hour will continue to impact portions of northern ME into northern NH through early evening. The greatest snowfall rates are expected across parts of central into northern ME. DISCUSSION...Heavy snow associated with an intense coastal low offshore of ME will continue to pivot north/northwest through the 21-00z time frame. Strong isentropic ascent is evident in water vapor satellite loops as the warm conveyor wraps around the north/northwest sides of the cyclone. Forecast soundings across northern portions of ME continue to indicate deep, saturated profiles through the dendritic growth zone. This will aid in efficient snowfall production, further aided by strong ascent and warm advection in the 850-700mb layer. The heaviest snowfall rates are expected from central into northern ME through 21-00z. Farther west, periods of heavy snow are possible into northern NH, aided by orographic influences. Though stronger forcing will be shifting east of this area over the next couple of hours. ..Leitman.. 12/03/2019 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...CAR...GYX...BTV...
