SHORT TERM...TONIGHT THROUGH THURSDAY NIGHT

SURFACE ANALYSIS SHOWS A COLD FRONT FROM NORTHERN MISSOURI...
EXTENDING INTO THE RED RIVER VALLEY OF TEXAS AND OKLAHOMA. THIS
FRONT WILL MOVE INTO NORTHWEST ARKANSAS LATE TONIGHT...WITH
SHOWERS AND THUNDERSTORMS DEVELOPING.

AS THE BOUNDARY GETS INTO CENTRAL ARKANSAS DURING THE DAY...IT
SHOULD SLOW DOWN A BIT...WITH ADDITIONAL PRECIP FIRING DURING THE
AFTERNOON AS AN UPPER WAVE MOVES THROUGH SOUTHEAST ARKANSAS AND
INTERACTS WITH THE BOUNDARY. THIS WILL PROLONG PRECIP OVER THE
SOUTHEAST HALF OF THE AREA INTO THE EVENING HOURS TUESDAY.

OTHERWISE...COOLER AND DRIER AIR WILL WORK ITS WAY IN BEHIND THE
FRONT...WITH PRECIP ENDING FROM NORTHWEST TO SOUTHEAST DURING THE
AFTERNOON IN THE NORTHWEST HALF AND OVERNIGHT IN THE SOUTHEAST
HALF.

HIGH PRESSURE WILL PUSH IN BEHIND THE FRONT ON WEDNESDAY...WITH
TEMPERATURES MUCH CLOSE TO SEASONAL AVERAGES. A WEAK...REINFORCING
BOUNDARY WILL MOVE THROUGH LATE THURSDAY...BUT WITH LITTLE DEEP
LAYER MOISTURE TO WORK WITH...NO PRECIPITATION IS EXPECTED AT THIS
POINT.

LONG TERM...FRIDAY THROUGH MONDAY

HIGH PRESSURE WILL BE OVER THE REGION FOR MUCH OF THE EXTENDED.
THIS WILL BRING COOLER TEMPERATURES FRIDAY AND SATURDAY...WITH THE
COOLEST READINGS SATURDAY AFTERNOON. THERE IS A CHANCE FOR FROST
ACROSS THE FAR NORTH AND NORTHEAST BOTH SATURDAY AND SUNDAY
MORNINGS.

THERE WILL BE A WARMING TREND STARTING SUNDAY...AS THE HIGH SLIDES
OFF TO THE EAST. THIS WILL ALLOW A COLD FRONT TO ENTER THE REGION
