...MULTIPLE ROUNDS OF SEVERE THUNDERSTORMS POSSIBLE THIS WEEK...
...SIGNIFICANT SEVERE THUNDERSTORM POTENTIAL TUESDAY...

THIS OUTLOOK IS FOR NORTHWEST AND WEST CENTRAL ARKANSAS AS WELL AS
MUCH OF EASTERN OKLAHOMA.

.DAY ONE...TONIGHT.

DISCUSSION...
SOUTHERLY WINDS OF 5 TO 20 MPH TONIGHT WILL HELP TO TRANSPORT LOW
LEVEL MOISTURE BACK INTO THE REGION. THIS WILL HELP TO DEVELOP
CLOUD COVER OVER EASTERN OKLAHOMA AND NORTHWEST ARKANSAS BY EARLY
MONDAY MORNING. NO HAZARDOUS WEATHER IS ANTICIPATED THROUGH
TONIGHT.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
SPOTTER ACTIVATION NOT EXPECTED.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY.
MONDAY...THUNDERSTORM POTENTIAL.
TUESDAY...SEVERE THUNDERSTORM POTENTIAL...HEAVY RAIN POTENTIAL.
WEDNESDAY AND THURSDAY...THUNDERSTORM POTENTIAL.
FRIDAY...SEVERE THUNDERSTORM POTENTIAL...HEAVY RAIN POTENTIAL.
SATURDAY...THUNDERSTORM POTENTIAL...HEAVY RAIN POTENTIAL.

EXTENDED DISCUSSION...
SEVERE WEATHER POTENTIAL INCREASES THIS WEEK...WITH POTENTIAL
SIGNIFICANT SEVERE WEATHER TUESDAY.

A FRONTAL BOUNDARY WILL CONTINUE TO BE ACROSS KANSAS ON
MONDAY...WITH THE DRYLINE EXTENDING ACROSS WESTERN OKLAHOMA.
DAYTIME HEATING AND CONVERGENCE NEAR THESE INTERSECTING BOUNDARIES
COULD INITIATE AN ISOLATED STORM OR TWO...ALTHOUGH THE FORECAST
CAP STRENGTH MAY PRECLUDE DEVELOPMENT ACROSS EASTERN OKLAHOMA AND
WESTERN ARKANSAS. IF A STORM DEVELOPS...ATMOSPHERIC PARAMETERS
WOULD FAVOR SEVERE STORMS...MAINLY ACROSS PARTS OF EASTERN
OKLAHOMA...WITH ALL SEVERE MODES POSSIBLE. THE SEVERE THREAT COULD
EXTEND INTO THE OVERNIGHT HOURS ON MONDAY IF A STORM DEVELOPS.

THE HIGHEST SEVERE WEATHER POTENTIAL CONTINUES TO BE TUESDAY EVENING
AND INTO THE OVERNIGHT HOURS...AS DRYLINE STORMS DEVELOP TO OUR
WEST AND MOVE EASTWARD. DETAILS CONTINUE TO BE REFINED BUT IT
DOES APPEAR THAT A SIGNIFICANT SEVERE WEATHER OUTBREAK MAY OCCUR
DURING THIS TIME FRAME...WITH ALL MODES OF SEVERE WEATHER
POSSIBLE...INCLUDING STRONG TORNADOES. THE SEVERE WEATHER THREAT
WILL CONTINUE ACROSS MAINLY SOUTHEAST OKLAHOMA AND NORTHWEST
ARKANSAS ON WEDNESDAY.

A LIMITED SEVERE WEATHER THREAT WILL EXIST ACROSS FAR SOUTHEAST
OKLAHOMA NEAR THE RED RIVER THURSDAY. THUNDERSTORM CHANCES RETURN
TO THE ENTIRE REGION THURSDAY NIGHT...FRIDAY AND SATURDAY AS THE
NEXT UPPER WAVE MOVES INTO THE ROCKIES. THIS WILL ALLOW FOR AT
LEAST A LIMITED SEVERE POTENTIAL CONTINUING INTO THE WEEKEND.
FLOODING COULD BECOME AN ISSUE DURING THIS TIME FRAME GIVEN THE
SEVERAL ROUNDS OF HEAVY RAINFALL THAT ARE ANTICIPATED DURING THE
WEEK.

EMERGENCY MANAGEMENT PLANNING STATEMENT...
FIRST RESPONDERS AND EMERGENCY MANAGEMENT PERSONNEL SHOULD REVIEW
SAFETY PLANS AND MAKE SEVERE WEATHER PREPARATIONS...AS THE
WEATHER PATTERN THIS WEEK SHOWS THE POTENTIAL FOR MULTIPLE ROUNDS
OF SEVERE WEATHER...ESPECIALLY TUESDAY WITH POSSIBLE SIGNIFICANT
SEVERE WEATHER.
