VALID 030028Z - 030130Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 332
CONTINUES.

SCT TSTMS HAVE BEEN ONGOING ALONG THE FRONT RANGE OF SRN CO/NRN
NM...WITH MORE ISOLATED CONVECTION MOVING S/SEWD OFF THE RATON MESA
INTO THE WRN TX/OK PANHANDLES. OVERALL CONVECTIVE INTENSITY HAS
APPEARED TO REMAIN MARGINALLY SEVERE AT ITS BEST...LIKELY OWING TO
WEAK INSTABILITY /MLCAPES AOB 1000 J/KG/ AND MODEST EFFECTIVE SHEAR
/AROUND 25 KTS/. WITH THE ONSET OF DIURNAL COOLING...EXPECT
CONVECTIVE COVERAGE/INTENSITY TO WANE ACROSS THE HIGH TERRAIN OF
SERN CO/NERN NM.

FARTHER S...AN ISOLATED SUPERCELL FORMED ALONG A STATIONARY FRONT
AND HAS DRIFTED VERY SLOWLY SWD INTO NRN CASTRO COUNTY TX. WITH
SURFACE DEW POINTS IN THE LOWER TO MIDDLE 60S TO THE S OF THIS
STORM...MODERATE INSTABILITY IS PRESENT WITH MLCAPES OF 1500 TO 2000
J/KG /PER MODIFIED 00Z AMA/MAF OBSERVED SOUNDINGS/. ALTHOUGH S/SELY
LOW-LEVEL INFLOW IS ANEMIC /AOB 10 KTS/...THE MAGNITUDE OF
INSTABILITY WOULD LIKELY AID IN MAINTAINING STRONG TO SEVERE
CONVECTIVE INTENSITY WITH STORMS ALONG AND N OF THE FRONTAL
BOUNDARY. FARTHER S...CLUMPING CU HAVE BEEN NOTED ALONG AND N OF AN
EAST TO WEST ORIENTED OUTFLOW BOUNDARY FROM AROUND 25 SW HOB TO BWD.
ATTM...THERE IS CONSIDERABLE UNCERTAINTY WHETHER ANY STORMS CAN
INITIATE IN THIS REGION GIVEN THE CAPPING INVERSION NOTED ON THE MAF
SOUNDING AND RATHER WEAK CONVERGENCE. THIS AREA WILL BE MONITORED
FOR A SEVERE TSTM WATCH IF ADDITIONAL STORMS CAN INDEED FORM.
