Mesoscale Discussion 0095 NWS Storm Prediction Center Norman OK 0715 AM CST Thu Feb 13 2025 Areas affected...Central and Northern New England...Northern New York... Concerning...Winter mixed precipitation Valid 131315Z - 131915Z SUMMARY...A mix of snow...sleet and freezing rain will move across northern New York and central New England this morning. Freezing rain rates could exceed 0.03 inches per hour in some areas. Heavy snow could develop in some areas across central and northern Maine. DISCUSSION...Heights will fall across the Northeast today, as a mid-level trough approaches from the west. Several areas of precipitation are ongoing in the Northeast. This is being supported by large-scale ascent ahead of the trough, and by strong low-level jet currently located in northern New York. At the surface, a strong thermal gradient is present with temperatures in New England ranging from the lower to mid 30s F over southern and central New England, and teens to single digits over central and northern Maine. In association with the low-level jet, a nose of warm air aloft is evident on forecast and observed soundings. This warm nose, with temperatures of 2 to 5 C, will favor a mixed precipitation type from northern New York eastward across northern New England into southern Maine. Freezing rain within this zone could exceed 0.03 inches per hour within the heavier pockets of precipitation. To the north of the zone, air aloft will be cold enough for snow. Localized heavy snow will be possible, mainly across parts of central and northern Maine. ..Broyles/Mosier.. 02/13/2025 ...Please see www.spc.noaa.gov for graphic product...
