Snowfall rates of 1-2 in/hr are possible within the heaviest band late this evening into the overnight hours. DISCUSSION...As of 0130 UTC, regional radar and surface analysis showed a broad area of stratiform precipitation ongoing across parts of the Mid Atlantic and southern New England. Associated with an approaching coastal low, periodic moderate to heavy snow/rain has been observed within this precipitation over the last several hours. Slow northeastward progression of the heaviest precip has been noted with the primary east-west oriented band stretching from east-central PA to Long Island Sound. Driven by strong low-level warm advection ahead of the deepening coastal low, moderate to heavy snow should slowly increase in coverage over portions of southern New England late this evening and into the overnight hours. Rates between 1 to 2 in/hour are possible within the primary band, though there remains some uncertainty on how quickly the heaviest snow will lift northward. Light snow has already been reported across parts of RI, MA and CT but, regional model soundings and observed ceilings above 4k feet suggest some low-level dry air remains in place. Inland moisture advection and the approach of the surface low should slowly cool and moisten the low-level thermodynamic profile sufficiently for higher snow rates after 03z. Periods of moderate to heavy snow will likely continue into the overnight hours. ..Lyons.. 01/07/2024 ...Please see www.spc.noaa.gov for graphic product...
