Area forecast discussion, Aug 5, 2:02 PM MDT, 3 hours 5 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE EL PASO TX/SANTA TERESA NM 200 PM MDT TUE AUG 5 1997 CONVECTION IS UP AND GOING EARLY TODAY. STORMS HAVE FIRED OVER THE SOUTHERN SACS IN RESPONSE TO DIFFERENTIAL HEATING, BUT WHAT'S A LITTLE UNUSUAL IS THAT WE HAVE A NORTHEAST FLOW THAT IS MOVING THE CONVECTION INTO FAR WEST TEXAS AND SOUTH CENTRAL NEW MEXICO. THE HIGH OVER ARIZONA IS WRAPPING SOME MONSOON MOISTURE ACROSS THE FA. AND WITH 700 MB TROF TO THE SOUTHEAST OF ELP, I EXPECT CHANCE OF CONVECTION TO BE PRETTY GOOD FOR ELP AND SURROUNDING AREA ALONG WITH THE USUAL CONVECTION OVER THE MOUNTAIN WITH A LESSER CHANCE OF T-STORM OVER THE WESTERN PART OF THE CWA TONIGHT. MOISTURE WILL NOT BE IN A HURRY TO LEAVE SO I WILL KEEP SOME KIND OF DECENT POPS IN THE FORECAST. NO STRONG SURFACE GRADIENT TO DRIVE WINDS BUT I DO EXPECT THEM TO BECOME A LITTLE MORE SOUTHEASTERLY OVER THE NEXT 24 HOURS. GUIDENCE TEMPS LOOK GOOD. BEST CHANCE FOR STORMS TOMORROW WILL BE OUT WEST AS MOISTURE ACCESS REMAINS THE STRONGEST THERE.
