EVENT...LOCALLY HEAVY RAINFALL FROM N GRANT COUNTY EWARD INTO CNTRL SIERRA
.
SATELLITE ANALYSIS AND TRENDS...NEGATIVELY TILTED SHORTWAVE TROF AXIS
APPEARS TO BE COINCIDENT WITH THE AZ/NM BORDER.  DPVA ASSOCIATED WITH THIS
FEATURE HELPING TO DESTABILIZE ATMOSPHERE AND IN RESPONSE CONVECTION HAS
RAPIDLY DEVELOPED ALONG THE HIGHER TERRAIN OF SW NM.  CONVECTION APPEARS
TO BE ANCHORED TO THE HIGHER TERRAIN IN N GRANT COUNTY WITH DEEP LEVEL
ESERLY FLOW ALLOWING FOR TRAINING INTO CNTRL SIERRA COUNTY.  GOES WEST
DIGITAL PRECIPITABLE WATER VALUES WERE SHOWING THAT PRECIPITABLE WATER
VALUES BETWEEN 0.9-1.0" WERE BEING TRANSPORTED BY ESE FLOW UP THE RIO
GRANDE VALLEY.  CONSIDERING AVAILABLE MOISTURE AND THE RELATIVELY SLOW
MOVING/TRAINING NATURE TO THE CONVECTION WOULD EXPECT THAT LOCAL RAINFALL
RATES IN EXCESS OF 1.0"/HR ARE QUITE POSSIBLE OVER GRANT/SIERRA COUNTIES.
MOST RECENT VIS IMAGE DOES SUGGEST THAT CONVECTION MAY BE TRYING TO
SLOWLY SLIP SOUTHWARD PRESUMABLY DUE TO STRENGTHENING OUTFLOW BOUNDARY.
WILL CONTINUE TO MONITOR.
