MD 0078 CONCERNING WINTER MIXED PRECIPITATION FOR PORTIONS OF NORTHERN AND CENTRAL IL INTO CENTRAL MO
Mesoscale Discussion 0078 NWS Storm Prediction Center Norman OK 0918 PM CST Tue Feb 20 2018 Areas affected...portions of northern and central IL into central MO Concerning...Winter mixed precipitation Valid 210318Z - 210915Z SUMMARY...Rain will transition to a wintry mix of freezing rain, sleet and snow across parts of northern and central IL into central MO over the next several hours. This wintry mix is expected to continue through the overnight hours, though precipitation rate should remain light. DISCUSSION...A slow, eastward-advancing cold front was draped from roughly northwestern IN into northwest AR this evening. Cooler temperatures are filtering southward across the mid-MS Valley, with readings generally in the 32-37 degree F range from near Chicago toward St. Louis and Springfield MO. Light to moderate precipitation was occurring over this area with mainly rain noted on the eastern edge of the MCD area with a mix of precip types further west. This transition from rain to a wintry mix will slowly progress eastward through 09z. Precipitation should generally remain light as heavier precipitation translates eastward with the front. Freezing rain rates up to 0.05 inches per 3 hours are expected through the night. Sleet and occasionally light snow may mix with freezing rain. ..Leitman.. 02/21/2018 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...LOT...ILX...LSX...DVN...SGF...
