DISCUSSION...
STORMS HAVE BEGUN TO DEVELOP ACROSS PARTS OF NORTHEAST TEXAS ALONG A
NEARLY STATIONARY BOUNDARY. GIVEN THE AMPLE MOISTURE IN PLACE...LIFT
IN THE VICINITY OF THE BOUNDARY AND LOCALLY ENHANCED SHEAR AND
HELICITY...STORMS WILL HAVE THE POTENTIAL TO BECOME SUPERCELLULAR IN
NATURE. STRONG ROTATING UPDRAFTS CAPABLE OF PRODUCING TORNADOES AND
LARGE HAIL WITH ANY STORM ACROSS SOUTHEAST OKLAHOMA THIS EVENING.
ELSEWHERE...MUCH OF AREA HAS CAUGHT A BREAK FROM THE RECENT SHOWER
AND THUNDERSTORM ACTIVITY THAT BROUGHT HEAVY RAIN AND FLOODING TO
PARTS OF THE REGION...AS RAINFALL AMOUNTS OF 2 TO 4 INCHES HAVE BEEN
COMMON ACROSS NORTHEAST OKLAHOMA AND FAR NORTHWEST ARKANSAS. ANOTHER
COMPLEX OF STORMS IS LIKELY TO FORM TO THE SOUTHWEST TONIGHT AND
MOVE NORTHEAST ACROSS PARTS OF EASTERN OKLAHOMA AND NORTHWEST
ARKANSAS LATE TONIGHT. WHILE MARGINALLY SEVERE WIND AND HAIL WILL BE
POSSIBLE...THE BIGGER THREAT WILL BE HEAVY RAIN AND FLASH FLOODING
AS THE ADDITIONAL RAIN FALLS OVER ALREADY SATURATED GROUND. THE
EXACT LOCATION OF THE HEAVIEST RAINFALL WHERE THE MAIN SURFACE
BOUNDARY SETS UP TONIGHT. IN ANY CASE...MUCH OF EASTERN OKLAHOMA AND
NORTHWEST ARKANSAS MAY SEE AN ADDITIONAL 1 TO 2 INCHES OF
RAINFALL...WITH AROUND 4 INCHES POSSIBLE IN THE VICINITY OF THE
SURFACE BOUNDARY.
SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...SPOTTER
ACTIVATION LIKELY WILL BE NEEDED OVER SOUTHEAST OKLAHOMA THIS
EVENING. EMERGENCY MANAGERS AREAWIDE SHOULD ALSO CONTINUE TO MONITOR
LATER FORECASTS CONCERNING FLASH FLOOD POTENTIAL OVER THE REST OF
THE AREA LATER TONIGHT.
.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY.
TUESDAY...THUNDERSTORM POTENTIAL...HEAVY RAIN POTENTIAL.
WEDNESDAY THROUGH SATURDAY...THUNDERSTORM POTENTIAL.
SUNDAY...NO HAZARDS.
EXTENDED DISCUSSION...
A COMPLEX OF STORMS WITH HEAVY RAINFALL WILL PERSIST INTO THE
MORNING HOURS BEFORE MOVING OUT OF THE AREA BY AFTERNOON. FLOODING
OF LOW LYING AREAS WILL LIKELY PERSIST THROUGH A GOOD PART OF
TUESDAY EVEN AFTER THE RAINFALL ENDS.
THE UPPER LEVEL STORM SYSTEM TO OUR WEST WILL BE VERY SLOW TO
MOVE EAST SO THUNDERSTORM CHANCES WILL PERSIST THROUGH SATURDAY.
HEAVY RAIN AND FLASH FLOODING WILL BE THE GREATEST THREAT WITH A
LESSER THREAT OF SEVERE WEATHER.
EMERGENCY MANAGEMENT PLANNING STATEMENT...

WEATHER.
