.MESOSCALE UPDATE...
THE REMNANTS OF THE MESOSCALE VORTICITY MAX IN SOUTHEAST
OKLAHOMA WILL TRACK ACROSS NORTHWEST ARKANSAS BETWEEN
08Z AND 11Z ALONG A FORT SMITH TO GREEN FOREST LINE.
THE APPROACH OF THE VORT MAX AND OROGRAPHICS WILL RESULT
IN A FEW THUNDERSTORMS OCCURRING IN NORTHWEST ARKANSAS
DURING THE LATE NIGHT HOURS. INSTABILITY WILL REMAIN
WEAK...BUT WIND FIELDS ALOFT WILL BE STRONG...SO AN
ISOLATED STRONG WIND GUST WILL BE POSSIBLE.
THE ARKANSAS RIVER VALLEY IS HOLDING DEW POINTS
IN THE LOW 60S...RESULTING IN SLIGHTLY LESS CAP AND SOME
WEAK SURFACE-BASED INSTABILITY. SO THE BEST CHANCE
OF A STRONG WIND GUST MIGHT BE IN THE FORT SMITH TO OZARK
AREA. AS AN INTERESTING NOTE...THE WRF-NAM SHOWS A
FAIRLY STRONG PRECIP SIGNAL AND SMALL SURFACE LOW
IN EASTERN CARROLL COUNTY AT 12Z...HINTING AT AN
ISOLATED STRONG STORM THERE.
WE CONTINUE TO SEE WIND GUSTS TO AROUND 45 MPH JUST
BEHIND THE PRECIP AREA IN THE CONVECTIVELY TIGHTENED
SURFACE PRESSURE GRADIENT.

DISCUSSION...
HE MAIN UPPER LEVEL STORM SYSTEM WAS LOCATED OVER THE ROCKY
MOUNTAIN REGION THIS MORNING...WITH A SURFACE COLD FRONT LOCATED
OVER NORTHWEST OKLAHOMA. THE UPPER SYSTEM WILL BEGIN TO LIFT EAST
AND NORTHEAST TODAY. SHOWER AND THUNDERSTORM ACTIVITY IS EXPECTED TO
INCREASE IN SIGNIFICANTLY IN AREAL COVERAGE BY MID TO LATE
AFTERNOON. SLOW MOVING THUNDERSTORMS THAT REDEVELOP OVER THE SAME
AREA WILL PRESENT A FLASH FLOOD THREAT LATE THIS AFTERNOON AND
EVENING...WHERE LOCALIZED AMOUNTS MAY APPROACH 3 TO 4 INCHES ACROSS
PARTS OF EASTERN OKLAHOMA. A FLASH FLOOD WATCH REMAINS IN EFFECT
TODAY AND TONIGHT...SEE /OKCFFATSA/ FOR DETAILS. THE THREAT OF SEVERE
WEATHER MAY BE HAMPERED THIS AFTERNOON BY ONGOING RAIN AND
THUNDERSTORM ACTIVITY...AS THIS WOULD RESULT IN INSTABILITY AND CAPE
VALUES NOT SUPPORTIVE OF SEVERE THUNDERSTORMS. AS A 100 KNOT UPPER
LEVEL JET AND THE COLD FRONT APPROACH TONIGHT...THE IMPROVED
DYNAMICS MAY RESULT IN HIGHER POTENTIAL FOR SEVERE STORMS VERY LATE
TONIGHT ACROSS SOUTHEAST OKLAHOMA AND WESTERN ARKANSAS. STRAIGHT
LINE WINDS APPEAR TO BE THE MAIN RISK FROM SEVERE STORMS
LATE...HOWEVER LOW AND MID LEVEL WIND FIELDS SUPPORT ROTATING STORMS
SHOULD ANY STORM MAINTAIN A STRONG UPDRAFT.
HOWEVER...THE LIMITING FACTOR WOULD BE STABILIZATION FROM PREVIOUS
CONVECTION. A DRY SLOT WILL PUSH INTO FAR WESTERN SECTIONS OF THE
OUTLOOKED AREA LATE TONIGHT...WHICH WILL MARK THE BEGINNING OF
DECREASED RAINFALL FROM SOUTHWEST TO NORTHEAST.
SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
SPOTTER ACTIVATION MAY BE NEEDED.

SATURDAY...THUNDERSTORM POTENTIAL.

EXTENDED DISCUSSION...
THE UPPER SYSTEM WILL QUICKLY LIFT NORTHEAST ON SATURDAY... HOWEVER
RAIN AND THUNDERSTORM CHANCES WILL REMAIN ACROSS FAR EASTERN
OKLAHOMA AND NORTHWEST ARKANSAS SATURDAY MORNING. SETTLED AND WARM
WEATHER IS EXPECTED FOR SUNDAY AND MONDAY. THUNDERSTORM CHANCES
RETURN AS A COLD FRONT MOVES THROUGH MONDAY NIGHT. A REINFORCING SH
SHOT OF COOLER AIR WILL APPROACH FROM THE NORTH LATER IN THE WORK
WEEK.

CONCERNING CONVECTIVE CHANCES NEXT WEEK.
