MD 0008 CONCERNING HEAVY SNOW FOR CENTRAL/EASTERN PA…SOUTHERN NY…NORTHERN NJ

Mesoscale Discussion 0008
NWS Storm Prediction Center Norman OK
0327 PM CST Sat Jan 06 2024

Areas affected…Central/Eastern PA…Southern NY…Northern NJ

Concerning…Heavy snow

Valid 062127Z – 070230Z

SUMMARY…Snowfall rates around 1″/hr appear probable across this
region, with some potential for 2″/hr rates,

DISCUSSION…A shortwave trough continues to progress quickly
northeastward across WV and VA. 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.
