SATELLITE ANALYSIS AND TRENDS...COMPACT UPPER LVL TROF LIFTING ENE ACROSS NE OK /NW AR/SW MO WILL PRODUCE LOCALLY MOD-LOCALLY HVY SNOWFALL RATES ACROSS PARTS OF AR/MO/IL/IN/KY AND OH OVER THE NEXT 6-12 HRS. PRECIP HAS STARTED TO INCRS IN COVERAGE/INTENSITY ACROSS SE MO/SRN IL OVER THE PAST 2-3 HRS WITH CLOUD TOP COOLING EVIDENT IN IR IMAGERY AS WELL. EXPRMTL MESOSCALE WIND ALGORITHM IS CURRENTLY IDENTIFYING THE AREA OF BEST UPPER LVL DVG TO BE OVER S CENTRAL/SE MO AND SW CORRELATING WITH THE ENHANCING PRECIP. SFC TEMPS ARE GNRLY IN THE LOW TO MID 30'S ACROSS NRN AR/MO/SRN IL/SRN IN BUT HAVE SOME ROOM TO COOL THROUGH EVAPORATIVE AND NIGHTTIME COOLING OVER THE NEXT FEW HRS TO TRANSITION FROM RAIN TO SNOW..WITH GRADUAL EXPANSION OF SNOW SEWD INTO NRN/WRN KY OVERNIGHT AS THE FRONT MOVES E. . SHORT TERM OUTLOOK VALID 2345-0545Z...MEDIUM CONFIDENCE FACTOR IN SHORT TERM OUTLOOK...S/WV TROF MOVING ENE WILL UTILIZE MOISTURE ALREADY DRAWN NWD INTO THE TN VLY BY THE PREVIOUS WAVE TO PRODUCE PRECIP ACROSS PARTS OF AR/TN/MO/IL/IN/KY/OH. GRADUAL COOLING WILL KEEP OR CHANGE PRECIP TO MOSTLY SNOW ACROSS SE MO/S IL/S IN DURING THE NEXT 3-6 HRS WITH EWD MOVING FRNTL BNDRY ALSO COOLING SFC TEMPS FROM W-E. SNOWFALL RATES MAY REACH AS HIGH AS 1"/HR IN DVLPG BANDS WITHIN THE DIFFLUENT ZONE OUT AHEAD OF THE TROF AXIS. WITH MODEL FCSTS SHOWING BEST UVV'S MOVING FROM SE MO TO SRN IN/SW OH DURING THE NEXT 6 HRS..EXPECT THESE AREAS ARE WHERE GREATEST CHC OF HVY SNOW RATES WILL OCCUR. . ....NESDIS IS A MEMBER OF 12 PLANET.... .
