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

.DAY ONE...THIS AFTERNOON AND TONIGHT

SCATTERED SHOWERS AND THUNDERSTORMS WILL BE NOTED ACROSS MUCH OF
ARKANSAS THROUGH THE REMAINDER OF THE EVENING AS AN UPPER LEVEL
SYSTEM MOVES EAST ACROSS NORTHERN ARKANSAS. THERE IS ONLY A SLIGHT
RISK FOR AN ISOLATED STRONG TO SEVERE THUNDERSTORM ACROSS SOUTHERN
PARTS OF THE STATES...WITH THE MAIN CONCERN BEING LARGE HAIL.

ACROSS NORTH AND NORTHWESTERN PORTIONS OF THE STATE...WHERE
TEMPERATURES WILL BE A LITTLE COOLER...THERE IS A SLIGHT CHANCE FOR
SOME SLEET MIXING IN WITH THE RAIN SHOWERS. NO ACCUMULATION IS
EXPECTED.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY

PARTS OF NORTHERN ARKANSAS WILL ONCE AGAIN SEE LOW TEMPERATURES
APPROACH THE FREEZING MARK MONDAY MORNING...WHERE A FREEZE WARNING
REMAINS IN EFFECT. PRECAUTIONS SHOULD BE TAKEN TO PROTECT TENDER
VEGETATION.

THE NEXT SIGNIFICANT STORM SYSTEM IS FORECAST TO AFFECT THE MID
SOUTH STARTING MONDAY NIGHT AND TUESDAY...WITH A GOOD CHANCE OF
SHOWERS AND THUNDERSTORMS. AT THIS TIME IT APPEARS THE SYSTEM WILL
TRACK SOUTH OF ARKANSAS...LIMITING THE POTENTIAL FOR WIDESPREAD
SEVERE WEATHER. HOWEVER...SOME OF THE STRONGER STORMS COULD PRODUCE
HAIL UP TO ONE INCH IN DIAMETER.

YET ANOTHER LOW PRESSURE WILL BRING SHOWER AND THUNDERSTORMS CHANCES
BACK TO THE NATURAL STATE WEDNESDAY NIGHT AND THURSDAY. ONCE
AGAIN...INDICATIONS ARE THAT THE LOW WILL PASS SOUTH OF ARKANSAS AND
KEEP THE AREA IN A SOMEWHAT COOL AIRMASS. THIS WOULD LIMIT THE
POSSIBILITY OF SEVERE WEATHER.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION IS NOT ANTICIPATED AT THIS TIME.
