MD 0086 CONCERNING HEAVY SNOW FOR NORTHEAST OHIO INTO FAR NORTHWEST PENNSYLVANIA AND EXTREME SOUTHWEST NEW YORK

Mesoscale Discussion 0086
NWS Storm Prediction Center Norman OK
1203 PM CST Sun Jan 22 2023
Areas affected...northeast Ohio into far northwest Pennsylvania and
extreme southwest New York
Concerning...Heavy snow
Valid 221803Z - 222000Z
SUMMARY...A couple hours of heavy snow may accompany the primary
band of precipitation exiting the OH Valley. A couple instances of
1+ inch/hour snowfall rates are possible.
DISCUSSION...A snow band with a history of producing brief bouts of
heavier snowfall rates continues to move northeast across OH in
tandem with deeper moisture and the approach of a mid-level trough.
Warm-air/moisture advection continues across the eastern OH Valley
toward the Appalachians, with tropospheric profiles remaining below
freezing from central/northeast OH into far northwest PA and extreme
southwest NY. Here, continued moistening of the dendritic growth
zone and 700 mb frontogenesis will promote enough lift for moderate
to occasional heavy snow, as already indicated by ASOS stations at
the Erie and Akron-Fulton International Airports. As such, 1+
inch/hr rates are still possible into early afternoon.
