... MIX OF WINTRY PRECIPITATION POSSIBLE SUNDAY AND SUNDAY NIGHT...
LOW PRESSURE OVER THE SOUTHERN PLAINS WILL MOVE JUST SOUTH OF THE QUAD STATE REGION ON SUNDAY. AS THE LOW APPROACHES... IT WILL SPREAD RAIN INTO THE AREA TONIGHT. AT THE SAME TIME... A COLD FRONT IS FORECAST TO PASS THROUGH THE REGION TONIGHT. BEHIND THE FRONT... MUCH COLDER AIR WILL BE DRAWN SOUTHWARD ON SUNDAY... RESULTING IN THE POTENTIAL FOR A MIX OF WINTRY PRECIPITATION.
WHILE THE POTENTIAL FOR A MIX WITH SNOW ON THE BACK SIDE OF THE DEPARTING SYSTEM HAS BEEN ANTICIPATED FOR SOME TIME... LATEST MODELS NOW SUGGEST THE SURGE OF COLD AIR ON SUNDAY WILL BE MUCH FASTER THAN EARLIER INDICATED. THIS MEANS THAT MORE OF THE PRECIPITATION WILL HAVE A CHANCE TO FALL AS SNOW... SLEET... AND PERHAPS A LITTLE FREEZING RAIN BEFORE IT COMES TO AN END SUNDAY NIGHT.
AT THE PRESENT TIME... INDICATIONS ARE THAT THE GREATEST ACCUMULATION OF SNOW AND SLEET WILL OCCUR ACROSS NORTHERN AND CENTRAL PORTIONS OF THE QUAD STATE REGION. THIS WOULD HAVE THE GREATEST IMPACT ON TRAVEL IN SUCH COMMUNITIES AS CAPE GIRARDEAU MISSOURI... CARBONDALE AND MARION ILLINOIS... EVANSVILLE INDIANA... AND HENDERSON AND OWENSBORO KENTUCKY. IN THIS ZONE... AT LEAST 1 TO 2 INCHES OF SNOW AND SLEET MAY ACCUMULATE SUNDAY AFTERNOON AND EVENING. EVEN IN AREAS THAT RECEIVE MAINLY RAIN... SUB-FREEZING TEMPERATURES SUNDAY NIGHT MAY RESULT IN THE DEVELOPMENT OF ICING... ESPECIALLY ON ELEVATED AND UNTREATED SURFACES.
AS THIS STORM APPROACHES... MODIFICATIONS TO PRECIPITATION TYPE... AMOUNTS... AND THE LOCATION OF GREATEST ACCUMULATION ARE ALL POSSIBLE. IT WOULD BE WISE TO KEEP IN TUNE TO THE LATEST FORECASTS ON THIS DEVELOPING WINTER WEATHER EVENT.
