Administrators NorthGeorgiaWX Posted January 16 Administrators Share Posted January 16 MD 0073 CONCERNING WINTER MIXED PRECIPITATION FOR PARTS OF THE MID ATLANTIC INTO SOUTHERN NEW ENGLAND Mesoscale Discussion 0073 NWS Storm Prediction Center Norman OK 0749 AM CST Tue Jan 16 2024 Areas affected...Parts of the Mid Atlantic into southern New England Concerning...Winter mixed precipitation Valid 161349Z - 161745Z SUMMARY...Locally moderate winter precipitation rates will spread northeastward this morning, with some modest ice accretion possible where freezing rain persists. DISCUSSION...A surface low currently off of the Mid Atlantic coast is forecast to gradually deepen as it moves northeast toward coastal southern New England this morning. Multiple waves of light to locally moderate precipitation are ongoing and will continue to spread northeastward in conjunction with the surface low. While interior portions of the Northeast will likely continue to see snow (with generally light to moderate rates) this morning, low-level warm advection will support a transition from snow to sleet across parts of southern New England, with freezing rain persisting over portions of the Mid Atlantic region. As the low deepens offshore, a modest uptick in precipitation intensity will be possible through the morning. While rates will likely remain light to locally moderate, antecedent cold conditions (with temperatures initially in the 20s F) may result in relatively efficient ice accretion in areas that transition to freezing rain. Pockets of moderate sleet/snow will also be possible into parts of southern New England. Low-level warm advection will support a gradual transition to rain along the Mid Atlantic and southern New England coasts, but subfreezing temperatures may persist inland through the morning. ..Dean.. 01/16/2024 ...Please see www.spc.noaa.gov for graphic product...
