Mesoscale Discussion 0124
NWS Storm Prediction Center Norman OK
0455 PM CST Thu Feb 03 2022
Areas affected...Ohio River Valley
Concerning...Winter mixed precipitation
Valid 032255Z - 040300Z
SUMMARY...Moderate to heavy mixed winter precipitation will likely
continue for the next several hours through the greater Ohio River
Valley region.
DISCUSSION...Surface observations and MPING reports along much of
the OH River Valley show a variety of precipitation types at the
surface, including freezing rain, sleet, and moderate to heavy snow.
The transition zone from mostly rain to frozen hydrometeors remains
fairly narrow with temperatures in the mid 30s noted in far
southeast OH and southern KY, quickly falling into the upper 20s in
central OH and southern IN. Latest RAP forecast soundings maintain a
persistent warm nose between 850 to 700 mb through the early evening
hours with only slight cooling with time. This is largely due to
continued warm advection along a tight mid-level baroclinic zone
draped over the region. Lift within this baroclinic zone and ahead
of the upper-level trough will continue through at least 02-04 UTC,
which should maintain areas of moderate to heavy mixed precipitation
for the next several hours.
