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

.DAY ONE...THIS AFTERNOON AND TONIGHT

A LARGE AREA OF LIGHT TO MODERATE RAIN COVERS MOST OF THE AREA AT
THIS TIME. ISOLATED THUNDERSTORMS ARE ALSO OCCURRING WITH THE
MAJORITY OF THE STRONGER STORMS OVER THE SOUTH. SOME OF THESE STORMS
OVER THE SOUTH HAVE BECOME SEVERE WITH DAMAGING WINDS AND LARGE
HAIL.

NUMEROUS OUTFLOW BOUNDARIES WERE GENERATED EARLIER TODAY BY A LARGE
AREA OF THUNDERSTORMS THAT MOVED ACROSS THE NORTH. THESE BOUNDARIES
WILL BECOME THE FOCAL POINT FOR REDEVELOPMENT THIS AFTERNOON.
SHOWERS AND THUNDERSTORMS ARE EXPECTED TO REDEVELOP STATE WIDE
DURING THE TIME OF MAXIMUM DAYTIME HEATING AS AN UPPER LEVEL
DISTURBANCE MOVES ALONG A STATIONARY FRONT DRAPED ACROSS THE CENTRAL
PART OF THE STATE AND INTERACTS WITH THESE AFOREMENTIONED BOUNDARIES.

A FEW OF THESE STORMS WILL BECOME SEVERE WITH MORE DAMAGING WINDS
AND LARGE HAIL POSSIBLE. THE FRONT IS EXPECTED TO BE PUSHED TO THE
SOUTH OVERNIGHT TAKING THE CHANCES OF RAIN AND SEVERE WEATHER WITH
IT. THE BEST CHANCES OF SEEING SEVERE WEATHER THIS AFTERNOON WILL BE
OVER THE SOUTH.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

NO HAZARDOUS WEATHER IS EXPECTED AT THIS TIME.

HIGH PRESSURE WILL SETTLE OVER THE REGION ON THURSDAY IN THE WAKE OF
THE FRONT AND WILL DOMINATE THROUGH THE WEEKEND AND INTO EARLY NEXT
WEEK. THE NEXT CHANCE OF ANY PRECIPITATION WILL NOT BE UNTIL MONDAY
AND THEN ONLY OVER THE NORTHWEST HALF OF THE STATE. TEMPERATURES
WILL REMAIN BELOW NORMAL THROUGH THE WEEKEND BEFORE A SLIGHT WARMING
TREND BEGINS.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION IS NOT ANTICIPATED.
