MD 0034 CONCERNING HEAVY SNOW FOR NORTHEAST OK…SOUTHEAST KS
Mesoscale Discussion 0034
NWS Storm Prediction Center Norman OK
0821 AM CST Sat Jan 11 2020
Areas affected...northeast OK...southeast KS
Concerning...Heavy snow
Valid 111421Z - 111615Z
SUMMARY...A short duration (1-2 hours) of heavy snowfall rates
around 1 inch per hour is expected this morning.
DISCUSSION...Radar imagery during the 7-8am CST period has shown a
blossoming of precipitation across north-central OK into southeast
KS as mid-level ascent becomes maximized over this region. Cushing,
OK recently reported heavy snow as of 755am CST. Forecast soundings
in northeast OK show 700-500 mb lapse rates around 7 degrees C per
km and weak upright instability (50-100 J/kg MUCAPE). Therefore,
weak convection resulting in bursts of heavy snow are seemingly
likely during the next 2 hours as the precipitation shield gradually
pivots east across northeast OK and southeast KS.
