VALID 221300Z - 231200Z

...THERE IS A SLGT RISK OF SVR TSTMS OVER PARTS OF THE MID
MS...OH...AND TN VLYS...

...THERE IS A SLGT RISK OF SVR TSTMS OVER PARTS OF FL...

...THERE IS A SLGT RISK OF SVR TSTMS OVER PARTS OF THE NRN PLNS/MID
MO VLY...

...SYNOPSIS...
LWR MS VLY UPR RDG WILL BUILD N INTO THE CNTRL PLNS THIS PERIOD AS
IT BEGINS TO RETROGRESS SLOWLY WWD. THE RDG WILL REMAIN BETWEEN
ANOMALOUS LOW OFF THE MID ATLANTIC CST...AND BROAD WRN TROUGH.
SATELLITE SHOWS AN IMPULSE NOW OVER UPSTATE NY MOVING S ALONG WRN
SIDE OF THE ERN LOW. THE DISTURBANCE SHOULD REACH ERN NC EARLY
TONIGHT. IN THE WEST...SATELLITE SHOWS WRN TROUGH EVOLVING INTO A
SPLIT FLOW PATTERN. TWO IMPULSES OF NOTE...ONE OVER WA/ORE AND THE
OTHER OVER CNTRL MT...LIKELY WILL AFFECT TSTM DEVELOPMENT OVER THE
NRN PLNS.

AT LWR LVLS...COLD FRONT NOW OVER THE NRN RCKYS WILL MOVE E INTO THE
NRN PLNS LATER TODAY/TONIGHT. A DIFFUSE...NEARLY STATIONARY
CONFLUENCE ZONE WILL PERSIST FROM THE MID MS/LWR OH VLY SSE INTO
GA...ON NE FRINGE OF UPR RDG. OTHERWISE...SFC FEATURES SHOULD
REMAIN RELATIVELY NONDESCRIPT.

...MID MS VLY SSE TO SRN APPALACHIANS...
SCTD CLUSTERS OF STRONG TO POSSIBLY SVR TSTMS ARE EXPECTED TODAY AS
DESTABILIZATION OCCURS ALONG AXIS OF DEEP CONFLUENCE EXTENDING FROM
IL/IND SSE INTO GA/WRN SC. MODERATE...DEEP NNW FLOW WILL SUPPORT
ORGANIZATION INTO SEVERAL SMALL FORWARD-PROPAGATING CLUSTERS THAT
COULD YIELD DMGG WIND AND PERHAPS MARGINALLY SVR HAIL THROUGH EARLY
THIS EVE.

...NRN PLNS/MID MO VLY...
RISING HEIGHTS SHOULD GRADUALLY SHUNT AREA OF WIDELY SCTD...
SLIGHTLY ELEVATED STORMS /LIKELY ARISING FROM MOIST LAYERS BETWEEN
800-700 MBS/ NOW OVER THE CNTRL PLNS NWD WITH TIME. LATER TODAY AND
TONIGHT...EXPECT SFC-BASED STORMS TO FORM ALONG COLD FRONT ENTERING
WRN ND. MORE ISOLD ACTIVITY MAY FORM IN CNTRL MT...AHEAD OF UPR
IMPULSE NOW OVER WA/ORE.

AMPLE INSTABILITY AND FAVORABLE DEEP-LAYER VEERING/SHEAR WILL BE
PRESENT FOR SVR HAIL/WIND IN ND...AND STRONGER WIND FIELD/DRIER
ENVIRONMENT MAY SUPPORT A FEW SPOTS OF HIGH WIND IN MT.
OVERALL...HOWEVER...CONFIDENCE IS NOT GREAT FOR WIDESPREAD STORM
DEVELOPMENT IN EITHER AREA. SOME OF THE STORMS COULD PERSIST INTO
THE NIGHT IN ND AND POSSIBLY REACH WRN MN LATER IN THE PERIOD.

...CNTRL/SRN FL...
STORMS SHOULD FORM OVER CNTRL AND S FL TODAY...AS MOIST ...VERY WARM
BOUNDARY LAYER DEVELOPS BENEATH SEASONABLY STRONG UNIDIRECTIONAL NLY
FLOW. STORMS MAY INITIATE ALONG WEAK W-E WIND SHIFT LINE NOW MOVING
S ACROSS NRN FL...AND/OR ALONG MERGING W CST/E CST SEA BREEZE
FRONTS. SATELLITE DATA SUGGEST THAT FOR SOME TIME TODAY REGION MAY
EXPERIENCE WEAK SUBSIDENCE IN WAKE OF APPARENT IMPULSE MOVING SSE ON
FRINGE OF ATLANTIC UPR LOW. IN ADDITION...MID LVL INVERSIONS ARE
PRESENT IN THE MORNING RAOBS AT TLH AND TPA. NEVERTHELESS...GIVEN
DEGREE OF EXPECTED SFC HEATING AND DEEP UNIDIRECTIONAL FLOW ROUGHLY
PARALLEL TO THE PENINSULA...POTENTIAL WILL EXIST FOR STORMS TO
ORGANIZE INTO SWD-MOVING CLUSTERS THAT COULD YIELD DMGG WIND.
DEPENDING UPON THE DEGREE OF STORM COVERAGE/OVERTURNING THAT OCCUR
THIS AFTN...THE SVR THREAT MAY LINGER AND PERHAPS LOCALLY INCREASE
TONIGHT AS REGION ONCE AGAIN COME UNDER THE INFLUENCE OF UPR
DIFFLUENCE/DPVA AHEAD OF NEXT IMPULSE ROTATING AROUND ATLANTIC LOW.

...CHESAPEAKE BAY REGION...
UVV AHEAD OF AFOREMENTIONED UPR IMPULSE...STRONG SFC HEATING...AND
DEEP...CYCLONIC...UNIDIRECTIONAL NLY FLOW MAY SUPPORT DEVELOPMENT OF
SHORT BANDS OF LOW-TOPPED STORMS. THESE COULD POSE A THREAT FOR
MARGINALLY SVR HAIL AND LOCALLY DMGG WIND THIS AFTN/EARLY TONIGHT
FROM ERN MD/DE INTO NE NC.
