Areas affected...OH...northern WV Panhandle...and western PA

Concerning...Heavy snow=20

Valid 020954Z - 021400Z

SUMMARY...Snowfall rates could exceed 1"/hr from OH into the
northern WV Panhandle and western PA over the next several hours.

DISCUSSION...Regional radar imagery shows a large area of moderate
to occasionally heavy snow across the middle/upper OH Valley, within
the northern periphery of the warm conveyor associated with a
shortwave trough moving into the lower OH Valley. The heaviest
snowfall is currently ongoing over the southern IN/OH border
vicinity, just downstream of a mid-level jetlet preceding the
shortwave. The general expectation is for this jetlet to progress
northeastward over the next few hours, with an attendant
northeastward shift of the heavy snowfall anticipated as well. This
shift would bring the highest snowfall rates, which could exceed
1"/hr, into central OH shortly and into eastern OH and western PA
later this morning.
