Lynn Hilton WINTER WEATHER OUTLOOK FOR SUNDAY THROUGH MONDAY FOR THE FOUR STATE REGION MAINLY ALONG AND NORTH OF INTERSTATE 20... A STRONG COLD FRONT HAS ALREADY MOVED THROUGH THE REGION AND COLDER AIR WILL FILTER INTO THE AREA OVER THE NEXT 24 HOURS. A SLOW MOVING UPPER LEVEL TROUGH CURRENTLY OVER SOUTHERN CALIFORNIA WILL SLOWLY MOVE EAST AND INTO THE TEXAS PANHANDLE BY MONDAY AFTERNOON. THE COMBINATION OF ABUNDANT MOISTURE AND LIFT FROM THE APPROACHING UPPER TROUGH WILL BRING INCREASING PRECIPITATION CHANCES TO THE AREA BEGINNING SUNDAY MORNING. WINTRY PRECIPITATION WILL BE POSSIBLE DUE TO THE COLD AIR THAT WILL BE IN PLACE. PRECIPITATION IS EXPECTED TO BEGIN SUNDAY MORNING AND EARLY SUNDAY AFTERNOON AS A MIX OF RAIN AND SLEET OVER SOUTHEAST OKLAHOMA AND PORTIONS OF SOUTHWEST ARKANSAS AND NORTHEAST TEXAS ROUGHLY ALONG AND NORTH OF INTERSTATE 30 WHILE LIQUID RAIN IS EXPECTED FARTHER SOUTH. AS SURFACE TEMPERATURES FALL TO NEAR OR BELOW FREEZING SUNDAY EVENING...A TRANSITION TO A MIX OF SNOW AND SLEET IS EXPECTED NORTH A LINE FROM MINEOLA TEXAS TO EL DORADO ARKANSAS. A MIXTURE OF RAIN...FREEZING RAIN...AND SLEET WILL BE POSSIBLE AS FAR SOUTH AS A LINE FROM TYLER TEXAS...TO SHREVEPORT AND FARMERVILLE LOUISIANA. TEMPERATURES SHOULD WARM ENOUGH BY MONDAY AFTERNOON FOR A TRANSITION TO ALL LIQUID RAIN. SNOW AND SLEET ACCUMULATIONS ACROSS SOUTHEAST OKLAHOMA...SOUTHWEST ARKANSAS...AND NORTHEAST TEXAS ARE EXPECTED TO BE LESS THAN AN INCH. THE GREATEST ICE ACCUMULATIONS...LESS THAN A TENTH OF INCH...ARE EXPECTED TO BE ACROSS EAST TEXAS WEST OF A LINE FROM MINEOLA TO LONGVIEW. CONSIDERABLE UNCERTAINTY STILL EXISTS REGARDING PRECIPITATION TYPE...AMOUNT...AND DURATION. WINTRY PRECIPITATION MAY CONTINUE LONGER THAN CURRENTLY EXPECTED IF TEMPERATURES FAIL TO WARM AS QUICKLY AS ANTICIPATED DURING THE DAY MONDAY...WHICH WOULD AFFECT ACCUMULATION AMOUNTS. THIS WINTER WEATHER EVENT IS STILL EVOLVING. AS MORE INFORMATION BECOMES AVAILABLE...THE FORECAST MAY CHANGE. RESIDENTS...TRAVELLERS...AND ANYONE WITH INTERESTS IN THE FOUR STATE REGION SHOULD PREPARE FOR THE POSSIBILITY OF WINTRY PRECIPITATION SUNDAY AND MONDAY...ESPECIALLY ALONG AND NORTH OF THE INTERSTATE 20 CORRIDOR.
