CONCERNING...SEVERE THUNDERSTORM WATCH 467...

VALID 030131Z - 030300Z

SEVERAL SEVERE TSTMS CONTINUE IN PARTS OF WW #467. EXPECT THIS
ACTIVITY TO CONTINUE TO SPREAD ESEWD THRU THE EVENING HOURS...HENCE
WW WILL LIKELY REMAIN IN EFFECT THRU EXPIRATION.

RECENT SFC ANALYSIS DEPICTS WEAK SFC LOW NEAR RTN WITH NOTICEABLE
BOUNDARY LAYER CONVERGENCE SSWWD TOWARDS TRUTH AND CONSEQUENCES AS
WELL AS NWWD FROM THE RTN AREA INTO SRN CO. AREA OF CONCERN HAS
SURFACE TEMPERATURES FROM THE UPPER 70S INTO THE LOW 90S WITH
DEWPOINT VALUES FROM THE MID 40S INTO THE LOW 50S...WHICH YIELDS
100MB MIXED CAPE VALUES FROM 500-1000 J/KG. A SIGNIFICANT PRESSURE
FALL AXIS EXISTS FROM AROUND RTN SSEWD INTO THE NWRN TX PANHANDLE
BETWEEN DHT AND LBB.

BOTH RECENT ETA40/RUC40 MODELS SUGGEST 850MB FLOW WILL INCREASE FROM
THE SSE AT 25-35 KTS IN THE NEXT 3-6 HOURS AND WILL COMBINE WITH
INCREASING MID-LVL FLOW ASSOCIATED WITH A WEAK ESEWD MOVING
SHORTWAVE TROUGH TO ALLOW STORMS TO CONTINUE SEWD INTO THE OVERNIGHT
PERIOD. AN INSPECTION OF THE UPSTREAM AMA RAOB REVEALS 7 C/KM
700-500MB LAPSE RATES...PW VALUES AROUND 0.75...LITTLE CINH...AND
RATHER LOW WBZ LEVELS. EXPECT ACTIVITY TO INCREASE IN COVERAGE ESEWD
BY OUTFLOW INTERACTION AND INCREASING ISENTROPIC UPGLIDE INTO SWRN

LARGE HAIL AND DAMAGING WINDS GUSTS.
