AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE EL PASO TX/SANTA TERESA NM 240 PM MDT TUE JUN 29 2010 .SYNOPSIS... DEEP LOW-LEVEL EASTERLY FLOW IS KEEPING MOISTURE OVER THE BORDERLAND. DAYTIME HEATING SHOULD HELP TO GENERATE ISOLATED TO SCATTERED STORMS FOR THE NEXT COUPLE OF AFTERNOONS AND EVENINGS. IN THE GULF OF MEXICO ALEX IS EXPECTED TO BECOME A WEAK HURRICANE AND TRACK WEST ACROSS MEXICO THURSDAY THROUGH SUNDAY. FORECAST MODELS INDICATE A SIGNIFICANT INCREASE IN MOISTURE FOR THE WEEKEND AS DEEP SOUTHERLY FLOW PULLS ADDED MOISTURE INTO THE REGION FROM THE REMNANTS OF ALEX TO OUR SOUTH. CURRENT THINKING IS THAT THE REGION WILL SEE INCREASING SHOWERS AND THUNDERSTORMS FOR THE WEEKEND. ABUNDANT CLOUD COVER WILL KEEP TEMPERATURES BELOW NORMAL. && .DISCUSSION... STILL A GOOD DEAL OF MOISTURE ACROSS THE FORECAST AREA AS EASTERLY WINDS CONTINUE AND DEEPEN. SURFACE DEWPOINTS AND PWS REMAIN HEALTHY. TODAY EXPECT SOME DOWN TICK IN THE AREAL COVERAGE OF STORMS AS THE UPPER SYSTEM THAT GOT STORMS STARTED OVER THE GILA HAS DIMINISHED AND MOVED NORTH...AND THE SURFACE FRONTAL BOUNDARY HAS SLIDE AWAY TO THE W AND S. THUS FOR THIS EVENING JUST ISOLATED STORMS INITIATED IN MOST PART TO OROGRAPHIC LIFT AND HEATING.

THUS WILL ADD A BIT TO THE POPS WITH ALL AREAS LOOKING TO GET EQUAL CHANCES FOR STORMS AND RAIN. THURSDAY NOT A LOT OF CHANGE IN THE WEATHER PATTERN SO NOT MUCH DIFFERENT IN THE FORECAST. THE BIG CHANGES INTRODUCED INTO THE GRIDS AND FORECAST BEGINNING FRIDAY AND LASTING THROUGH THE WEEKEND AS LATEST MODELS ARE STRONGLY SUGGESTING THAT ALEX TAKES A WESTWARD TRACK ACROSS MEXICO. BOTH THE NAM AND THE GFS SHOW DEEP SOUTHERLY FLOW INGESTING A LOT OF ALEXS' MOISTURE AND BRINGING IT UP OVER THE CWFA BEGINNING FRIDAY MORNING. THUS HAVE ADJUSTED THE GRIDS TO ADD A LOT OF CLOUDS...COOLER TEMPS...HIGHER POPS/QPF FOR THE FRI-SAT-SUN PERIODS. && .AVIATION...VALID 30/00Z-01/00Z EAST WINDS WILL CONTINUE TO BRING MOISTURE INTO THE AREA FOR THE NEXT 36 HOURS. ONLY ISOLATED CONVECTION IS EXPECTED NEAR THE TAFS SITES THIS EVENING. THERE MIGHT BE ISOLATED HEAVY RAINS AND STRONG WINDS ASSOCIATED WITH THESE STORMS.
