THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF SOUTH CENTRAL
ARKANSAS...SOUTHWEST ARKANSAS...NORTH CENTRAL LOUISIANA...
NORTHWEST LOUISIANA...SOUTHEAST OKLAHOMA...EAST TEXAS AND
NORTHEAST TEXAS.

.DAY ONE...TONIGHT...
TEMPERATURES SHOULD NOT BE AS COLD TONIGHT WITH LOWS MOSTLY
IN THE 20S TO LOWER 30S. THE COLDEST TEMPERATURES WILL BE
FELT ACROSS EXTREME NORTHEAST TEXAS...SOUTHEAST OKLAHOMA
AND SOUTHWEST ARKANSAS WHERE A SNOW PACK REMAINS ON THE
GROUND FROM THE WINTER STORM THURSDAY NIGHT THROUGH
FRIDAY. THIS SNOW...ALONG WITH LIGHT SOUTH WINDS TONIGHT...
COULD RESULT IN PATCHY FREEZING FOG ACROSS THE REGION. THIS
WOULD RESULT IN RIME ICE FORMING ON AREA ROADWAYS THAT MAY
HAVE ALREADY DRIED OUT FROM THE MELTING SNOW. LATE TONIGHT...
THE LEADING EDGE OF AN UPPER LEVEL STORM SYSTEM WILL MOVE
ACROSS CENTRAL OKLAHOMA INTO THE REGION FROM THE WEST.
THIS SYSTEM WILL HAVE THE CAPABILITY TO PRODUCE LIGHT
FREEZING RAIN OR FREEZING DRIZZLE ACROSS MAINLY SOUTHEAST
OKLAHOMA INTO EXTREME SOUTHWEST ARKANSAS. IF THIS PRECIPITATION
MATERIALIZES LATE TONIGHT...ONLY VERY LIGHT ACCUMULATIONS
WOULD BE EXPECTED.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY...
THE UPPER LEVEL STORM SYSTEM MOVES INTO THE SOUTHERN PLAINS AND
LOWER MISSISSIPPI VALLEY DURING THE DAY SUNDAY INTO SUNDAY NIGHT.
THIS SYSTEM WILL NOT HAVE A GOOD FETCH OF MOISTURE TO WORK WITH...
BUT THE DYNAMICS OF THE SYSTEM...ALONG WITH THE COLD AIR ASSOCIATED
WITH IT...WILL SUPPORT A MIXTURE OF RAIN AND SNOW LATE IN THE DAY
SUNDAY. THIS MIXTURE SUNDAY AFTERNOON WILL BE FELT MAINLY ALONG
AND NORTH OF THE INTERSTATE 30 CORRIDOR OF NORTHEAST TEXAS...
SOUTHEAST OKLAHOMA AND SOUTHWEST ARKANSAS. LATER SUNDAY NIGHT...
THE RAIN AND SNOW MIXTURE WILL BE POSSIBLE FURTHER SOUTH...INCLUDING
THE INTERSTATE 20 CORRIDOR OF NORTHEAST TEXAS...INTO NORTHERN
LOUISIANA. THE SYSTEM SHOULD EXIT THE REGION LATE SUNDAY NIGHT INTO
EARLY MONDAY. ANY SNOWFALL ACCUMULATIONS WITH THIS STORM SYSTEM
SUNDAY INTO SUNDAY NIGHT WOULD BE LIGHT...IF ANY.

A MUCH MORE SIGNIFICANT WINTER STORM...EFFECTING THE ENTIRE FOUR
STATE REGION...WILL BE MOVING INTO THE FOUR STATE REGION WEDNESDAY
INTO WEDNESDAY NIGHT. THIS DISTURBANCE WILL HAVE MUCH MORE
MOISTURE TO WORK WITH AND MUCH MORE IN THE WAY OF COLDER AIR AS
WELL. WHILE THE STORM SYSTEM IS STILL SEVERAL DAYS AWAY...IT
APPEARS THAT SIGNIFICANT SNOW AND ICE ACCUMULATIONS WILL BE
POSSIBLE FOR THE REGION WEDNESDAY INTO WEDNESDAY NIGHT. THE
EVOLUTION OF THIS STORM SYSTEM WILL CONTINUE TO BE MONITORED
CLOSELY AS THE EVENT NEARS.
