Areas affected...Pennsylvania...New Jersey...Northern West
Virginia...Northern Virginia...Northern Delaware...New Jersey...Far
Southeast New York

Concerning...Heavy snow

Valid 251101Z - 251700Z

SUMMARY...Heavy snowfall, with rates of around 1 inch per hour, is
expected to continue to develop from parts of the upper Ohio Valley
eastward to the Mid-Atlantic this morning.

DISCUSSION...The latest mosaic radar imagery shows widespread
snowfall ongoing from the Ohio Valley eastward into the
Mid-Atlantic. This is occurring along a broad zone of strong
isentropic ascent, aided by warm advection associated with a 50 to
60 knot low-level speed max over the southern Appalachians. The exit
region of this feature will continue to move northward this morning
into the upper Ohio Valley and northern Mid-Atlantic, helping to
gradually intensify snowfall rates. This will result in areas of
heavy snow from Pennsylvania and northern Virginia eastward to New
Jersey and far southeastern New York. Snowfall rates of 1 inch per
hour will be possible within the more well-defined bands that setup.
The heavy snowfall potential from Pennsylvania and New Jersey
northward should continue through the mid to late morning. In
northern Virginia, Maryland and Delaware, a changeover to freezing
rain is expected by late morning.
