Mesoscale Discussion 0023
NWS Storm Prediction Center Norman OK
0855 AM CST Sat Jan 17 2026
Areas affected...northern NJ into southwest New England
Concerning...Heavy snow
Valid 171455Z - 171800Z
SUMMARY...Transient heavy snow is expected to shift northeastward in
the Northeast to southwest New England through early afternoon.
Rates should briefly reach 1 inch per hour before waning.
DISCUSSION...A confined band of moderate to heavy snow with several
half to quarter-mile visibilities ongoing across mainly southeast
PA, north-northwest of the Philadelphia Metro Area, in association
with a shortwave impulse progressing northeastward across the
Northeast. 12Z observed and forecast soundings indicate the
dendritic growth zone is centered between 575-650 mb. Ascent within
and below this level appears likely to peak through about 18Z, which
should favor snowfall rates around 1 in/hr. This should be transient
at any one location as the burst of heavy snow shifts northeastward
followed by drying in the dendritic growth layer.
