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

.DAY ONE...THIS AFTERNOON AND TONIGHT

THE COMBINATION OF AFTERNOON HEATING...ALONG WITH WARM AND HUMID
CONDITIONS OVER ARKANSAS...WILL RESULT IN THE DEVELOPMENT OF WIDELY
SCATTERED SHOWERS AND THUNDERSTORMS THIS AFTERNOON. BETTER CHANCES
WILL EXIST OVER NORTHWEST ARKANSAS AS AN UPPER LEVEL IMPULSE IS
FORECAST TO APPROACH THE AREA FROM OKLAHOMA.

WHILE THE CHANCES OF ORGANIZED SEVERE WEATHER WILL REMAIN LIMITED...
A FEW STORMS WILL BE CAPABLE OF PRODUCING GUSTY WINDS OF 40 TO 50
MPH...SMALL HAIL AND LOCALLY HEAVY RAINFALL. MOST OF THE ACTIVITY IS
EXPECTED TO DIMINISH SHORTLY AFTER SUNSET THIS EVENING.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY

SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE IN THE FORECAST
FROM MONDAY THROUGH WEDNESDAY NIGHT. THE HIGHER CHANCES FOR STORMS
WILL BE NORTH ON MONDAY. TUESDAY WILL SEE MORE NUMEROUS SHOWERS AND
STORMS AS A COLD FRONT APPROACHES OUR FORECAST AREA. THERE WILL
EXIST THE POSSIBILITY OF SEVERE STORMS ON TUESDAY...MAINLY OVER THE
WESTERN SECTIONS OF THE STATE. SOME OF THE STORMS ON TUESDAY MAY
DROP HEAVY RAINFALL AMOUNTS IN SOME SPOTS...BUT THIS WILL NEED TO BE
MONITORED MORE CLOSELY AS WE GET CLOSER IN TIME. DRY WEATHER WILL
RETURN FROM THURSDAY ONWARD INTO SATURDAY.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION IS NOT ANTICIPATED AT THIS TIME.
