MD 0053 CONCERNING FREEZING RAIN FOR OK PANHANDLE…WESTERN/NORTH-CENTRAL KS…SOUTH-CENTRAL/SOUTHEAST NE…FAR NORTHWEST MO…EXTREME SOUTHWEST IA
Mesoscale Discussion 0053 NWS Storm Prediction Center Norman OK 0159 PM CST Sun Jan 15 2017 Areas affected...OK panhandle...western/north-central KS...south-central/southeast NE...far northwest MO...extreme southwest IA Concerning...Freezing rain Valid 151959Z - 160100Z SUMMARY...A large area of freezing rain is expected to persist through the afternoon and into the evening. Freezing rain rates from 0.02 to 0.05 inch an hour are possible. DISCUSSION...Large area of light to moderate precipitation associated with warm conveyor of the negatively-titled upper low centered near El Paso will continue to expand northward/northeastward over the next several hours. As a result, the area of freezing rain across northeast KS will move into far southeast NE during the next hour or two. Surface observation at CNK in northeast KS reported 0.05 inches of freezing rain and 0.04 inches of ice accretion in the past hour, with these rain rates expected to continue as the area moves into southeast NE. Another area of precipitation across southwestern KS is expected to move northward/northeastward into more of west-central KS. Freezing rain rates have been lighter here than areas northeastward (generally around 0.02 inches per hour) but prolonged nature of the event has lead to significant ice accretion. The 18Z observations at RSL and GCK reported 0.18 and 0.13 inches of ice accretion, respectively, over the past 6 hours. Convectively enhanced area of precipitation across northeast NM and the western TX panhandle is expected to gradually move northward/northeastward within the warm conveyor, taking it into the central/eastern OK panhandle and southwestern KS around 23-00Z. Surface temperatures are expected to remain at or just below freezing with overall thermal profiles remaining supportive of freezing rain. ..Mosier.. 01/15/2017 ...Please see www.spc.noaa.gov for graphic product...
