…A MIXTURE OF WINTER AND SEVERE WEATHER WILL BE POSSIBLE CHRISTMAS
DAY THROUGH CHRISTMAS NIGHT ACROSS PORTIONS OF THE FOUR STATE
REGION…

A VIGOROUS UPPER LEVEL STORM SYSTEM WILL DIG THROUGH THE TEXAS
PANHANDLE REGION CHRISTMAS EVE NIGHT AND INTO THE RED RIVER
VALLEY AND NORTH TEXAS CHRISTMAS DAY. A WARM FRONT WILL BEGIN TO
RETURN NORTH INTO DEEP EAST TEXAS AND NORTHCENTRAL LOUISIANA EARLY
CHRISTMAS MORNING…WITH SHOWERS AND THUNDERSTORMS RAPIDLY
DEVELOPING ALONG AND NORTH OF THIS FRONTAL BOUNDARY AFTER MIDNIGHT
CHRISTMAS MORNING. GIVEN THE EXTENT OF SHEAR AND STRONG
INSTABILITY ALOFT…SOME OF THESE STORMS MAY BECOME SEVERE EARLY
CHRISTMAS MORNING…WITH LARGE HAIL AND POSSIBLE DAMAGING WINDS
THE PRIMARY THREATS. THE SEVERE WEATHER THREAT MAY CARRY OVER
THROUGH THE AFTERNOON CHRISTMAS DAY…AS ADDITIONAL UPPER LEVEL
ENERGY AHEAD OF THIS STORM SYSTEM OVERSPREADS OUR REGION. SHOULD
THIS THREAT MATERIALIZE AND LOW LEVEL SHEAR AND INSTABILITY
INCREASE…THE THREAT FOR ISOLATED TORNADOES WILL EXIST IN
ADDITION TO DAMAGING WINDS AND LARGE HAIL. LOCALLY HEAVY RAINFALL
WILL ALSO BE POSSIBLE IN THE STRONGER STORMS.

IN ADDITION TO THE SEVERE WEATHER THREAT CHRISTMAS DAY…WINTER
WEATHER WILL BE POSSIBLE LATE TUESDAY AFTERNOON OVER SOUTHEAST
OKLAHOMA AND OVER PORTIONS OF EXTREME NORTHEAST TEXAS…SOUTHWEST
ARKANSAS…AND EXTREME NORTHERN LOUISIANA CHRISTMAS NIGHT. A
STRONG COLD FRONT WILL SURGE SOUTHEAST INTO NORTHEAST
TEXAS…SOUTHEAST OKLAHOMA…AND SOUTHWEST ARKANSAS CHRISTMAS
AFTERNOON AND NIGHT NEAR THE COLD CORE CENTER OF THIS STORM
SYSTEM…WITH RAIN GRADUALLY CHANGING OVER TO SNOW. SHOULD THIS
STORM TRACK AND TIMING OF THE COLDER SUBFREEZING AIR
VERIFY…SNOWFALL ACCUMULATIONS OF ONE TO THREE INCHES WILL BE
POSSIBLE OVER MCCURTAIN COUNTY OKLAHOMA AS WELL AS THE NORTHERN
SECTIONS OF SOUTHWEST ARKANSAS…GENERALLY NORTH OF AN
ASHDOWN…TO HOPE AND BLUFF CITY LINE. THE RAIN SHOULD CHANGE OVER
TO SNOW ALONG THE INTERSTATE 30 CORRIDOR OF NORTHEAST TEXAS AND
THE REMAINDER OF SOUTHWEST ARKANSAS TUESDAY EVENING…BUT ONLY A
DUSTING IS EXPECTED AT THIS TIME. THE RAIN MAY MIX WITH SNOW LATE
CHRISTMAS NIGHT NORTH OF THE INTERSTATE 20 CORRIDOR OF NORTH
LOUISIANA…BUT NO SNOW ACCUMULATIONS ARE EXPECTED AT THIS TIME.

UNCERTAINTIES WITH THE EXACT TRACK AND TIMING OF THIS STORM SYSTEM
STILL REMAIN…AND A NORTHWARD TRACK WOULD RESULT IN A REDUCED THREAT
OF WINTER WEATHER AND AN INCREASED THREAT OF SEVERE WEATHER FOR
THE REGION. A MORE SOUTHWARD TRACK WOULD RESULT IN GREATER SNOW
ACCUMULATIONS FARTHER SOUTH ACROSS NORTHEAST TEXAS AND SOUTHWEST
ARKANSAS…WITH A REDUCED THREAT OF SEVERE WEATHER OVER DEEP EAST
TEXAS AND NORTHCENTRAL LOUISIANA.

RESIDENTS ACROSS THE FOUR STATE REGION SHOULD STAY TUNED TO THE LATEST
STATEMENTS AND FORECASTS IN THE NEXT COUPLE DAYS FROM THE NATIONAL
WEATHER SERVICE IN SHREVEPORT CONCERNING THE POTENTIAL FOR WINTER
AND SEVERE WEATHER CHRISTMAS DAY AND NIGHT.
