Mesoscale Discussion 0091
   NWS Storm Prediction Center Norman OK
   0144 PM CST Mon Feb 15 2021

   Areas affected...northeastern Kentucky...southern/eastern
   Ohio...western/central Pennsylvania...northern West Virginia

   Concerning...Freezing rain 

   Valid 151944Z - 160145Z

   SUMMARY...Precipitation will expand from southwest to northeast
   across the discussion area.  0.05 to 0.10 inch per 3-hour
   accumulations of freezing rain are expected.

   DISCUSSION...Radar mosaic imagery continues to indicate an expanding
   precipitation shield across the majority of the state of Kentucky
   atop a shallow, sub-freezing airmass.  The precipitation continues
   to outpace northeastward-movement of most model guidance outside of
   certain CAMS (Nam3, HRRR).  These CAMS indicate continued
   northeastward progression of icing (freezing rain and some sleet)
   into Ohio/northern West Virginia over the next hour or so and
   southwestern Pennsylvania after around 22Z or so.  Upstream
   observations have indicated localized precipitation rates ranging as
   high as 0.05 to 0.10 inch per hour in heavier bands/convective
   elements, and the expectation is that this will continue with
   northeastward extent across the discussion area over the next 6
   hours.  At least 3-6 hours of icing is expected areawide.
   Additionally, a few areas of sleet (or even snow) are expected to
   mix in with freezing rain - especially across the northern extent of
   the discussion area where deeper cold air is present.
