MD 0057 CONCERNING SNOW SQUALL FOR PORTIONS OF EXTREME NORTHEAST PENNSYLVANIA…FAR EASTERN NEW YORK…MASSACHUSETTS…VERMONT…NEW HAMPSHIRE
Mesoscale Discussion 0057 NWS Storm Prediction Center Norman OK 1039 AM CST Wed Jan 29 2025 Areas affected...portions of extreme northeast Pennsylvania...far eastern New York...Massachusetts...Vermont...New Hampshire Concerning...Snow Squall Valid 291639Z - 291845Z SUMMARY...Occasional snow-squall conditions are possible in stronger portions of a snow band over the next few hours. A rapid onset of moderate snow, gusty winds, and reduced visibility may all occur. DISCUSSION...A low-topped, progressive convective snow band has recently materialized, with a 10 F surface temperature drop, moderate snowfall rates, and half-mile visibility reductions noted on surface observations over the past couple of hours. This band is being driven by a progressive cold front and rapidly ejecting mid-level trough, which is also preceded by at least partially clearing skies. 16Z mesoanalysis shows up to 8 C/km low-level lapse rates downstream of the snow band, suggesting that snow squall potential may increase this afternoon in stronger convective cells. Bouts of at least moderate snowfall rates, as well as a 10 F temperature drop, 25+ kt gusts, and visibility reduced to a quarter mile, may occur with this band until it moves offshore. ..Squitieri.. 01/29/2025 ...Please see www.spc.noaa.gov for graphic product...
