Areas affected...northern Ohio... much of Pennsylvania... northern
Maryland... far northeastern West Virginia... far southwestern New
York
Concerning...Heavy snow
Valid 192324Z - 200230Z
SUMMARY...Moderate to heavy snowbands continue to overspread the
region, with widespread 1-2 inch per hour snowfall rates likely.
DISCUSSION...Regional radar shows moderate to heavy snowbands
continuing over portions of northern Ohio, and developing/spreading
into portions of Pennsylvania and northern Maryland. Locations where
these snowbands have setup are currently experiencing snowfall rates
of 1-2 inches per hour.
These observational trends are expected to continue for the next few
hours. Strong mid-level frontogenetical forcing is resulting in
broad vertical ascent over the region. RAP soundings indicate
moderate vertical motion through the dendritic growth zone, helping
to enhance snowfall rates. With time, areas of northern Maryland and
southern Pennsylvania should transition to rain, but could
experience some brief freezing rain as warm air advection aloft
outpaces warming at the surface.
