MD 0079 CONCERNING WINTER MIXED PRECIPITATION FOR PORTIONS OF NORTHERN OKLAHOMA…SOUTHERN/EASTERN KANSAS…AND WESTERN MISSOURI
Mesoscale Discussion 0079
NWS Storm Prediction Center Norman OK
0751 PM CST Wed Feb 06 2019
Areas affected...Portions of northern Oklahoma...southern/eastern
Kansas...and western Missouri
Concerning...Winter mixed precipitation
Valid 070151Z - 070745Z
SUMMARY...Winter mixed precipitation will develop across portions of
northern Oklahoma, southern/eastern Kansas, and western Missouri
tonight. Heavy freezing rain/sleet are possible.
DISCUSSION...A strong upper-level trough is moving onto the Plains
this evening and a strengthening low-level jet is increasing
warm-air advection above a cold air mass across Kansas/Oklahoma. A
couple of elevated multi-cellular convective clusters are moving
along the northern edge of the low-level jet/warm-air advection.
Mid-level lapse rates are steepening as cold air aloft spreads
eastward, which will increase coverage of storms/showers in the next
couple of hours across portions of northern Oklahoma,
southern/eastern Kansas, and western Missouri. The warm-nose should
remain in place tonight within the MCD area at 850-700 mb with below
freezing surface temperatures resulting in freezing rain and sleet.
MUCAPE of 250-1000 J/kg and mixed-phase clouds should result in CG
lightning and could produce locally heavy freezing rain/sleet.
Generally, precipitation rates will be 0.05-0.15" per hour with
widespread ice accumulation expected. In areas with stronger surface
winds, ice accretion will be more efficient and sleet accumulation
is also possible within convective bands/showers.
