A broad precipitation field covers much of the northern Mid-Atlantic states as well as NY, supported by moderate to strong low-level warm advection ahead of the wave. Occasionally heavy snow has been noted across the region over the past few hours, particularly across western and southern PA, where the low-level warm advection/frontogenesis is being augmented by large-scale forcing for ascent near the shortwave trough. This general trend is expected to continue over the next several hours, with heavy snow shifting from western/central PA into western/southern NY. Snowfall rates around 1"/hr appear probable across this region, with some potential for 2"/hr rates, particularly just north of the leading edge of the mid-level dry air. ..Mosier.. 01/06/2024 ...Please see www.spc.noaa.gov for graphic product...
