THIS HAZARDOUS WEATHER OUTLOOK IS FOR A LARGE PART OF ARKANSAS.

.DAY ONE...TODAY AND TONIGHT

A WARM FRONT SITUATED JUST SOUTH OF ARKANSAS COULD PRODUCE SOME
SCATTERED STORMS THIS AFTERNOON IN SOUTHERN ARKANSAS. SHOULD ANY
CONVECTION REDEVELOP IN THE VICINITY OF THIS BOUNDARY...MOST OF IT
SHOULD STAY SOUTH OF THE FORECAST AREA. HOWEVER AN ISOLATED STRONG
STORM IS NOT OUT OF THE QUESTION.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

THE WARM FRONT...CURRENTLY SOUTH OF ARKANSAS...WILL LIFT NORTH
ACROSS ARKANSAS ON THURSDAY AS A SYSTEM STRENGTHENS TO THE NORTH
OF ARKANSAS. THIS SYSTEM WILL THEN DRAG A COLD FRONT THROUGH THE
STATE ON FRIDAY. RAIN CHANCES WILL INCREASE SOMEWHAT ON
THURSDAY...THEN SIGNIFICANTLY ON FRIDAY.

SOME SCATTERED STORMS WILL OCCUR ON THURSDAY AS THE WARM FRONT
LIFTS THROUGH. SOME OF THESE STORMS WILL HAVE THE POTENTIAL TO
BECOME SEVERE...WITH THE BEST CHANCES BEING IN THE NORTHERN PARTS
OF THE STATE. THE MAIN THREATS WILL BE DAMAGING WINDS AND HAIL.
MORE WIDESPREAD SHOWERS AND THUNDERSTORMS WILL EXIST ON FRIDAY AS
THE COLD FRONT MOVES THROUGH. AGAIN...SOME WILL HAVE POTENTIAL TO
BECOME SEVERE AND THE THREATS WILL BE THE SAME AS ON THURSDAY.

EVEN WITH RAINFALL IN THE FORECAST...THE FIRE DANGER WILL REMAIN A
CONCERN DUE TO THE SIGNIFICANT DROUGHT ACROSS THE AREA. BURN BANS
ARE IN PLACE IN MANY COUNTIES OF ARKANSAS...AND ANY UNCONTROLLED OR
ACCIDENTAL FIRE COULD QUICKLY GROW OUT OF CONTROL.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION IS NOT ANTICIPATED.
