AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE EL PASO TX/SANTA TERESA NM 245 PM MDT WED SEP 15 2010 .SYNOPSIS... WE WILL SEE ONLY A SLIGHT CHANCE FOR RAIN EACH DAY THROUGH THE WEEKEND. TEMPERATURES WILL CONTINUE TO RUN WELL ABOVE NORMAL AS HIGH PRESSURE WILL CONTROL OUR WEATHER THROUGH THE END OF THE WEEK. && .DISCUSSION... DRIER AIR WAS MOVING INTO THE AREA THIS AFTERNOON. OUT WEST DEW POINTS WERE IN THE 50'S THIS MORNING...NOW THEY HAVE DROPPED TO THE UPPER 30'S. EAST OF THE RIO GRANDE DEW POINTS ARE STILL IN THE 50'S AND GUESS WHAT...THAT IS WHERE THE CONVECTION HAS STARTED TO POP UP. THE DRIER AIR WILL CONTINUE TO MOVE IN FOR THE NEXT 48 HOURS AND THOUGH I CAN'T COMPLETELY RULE OUT ANY RAIN...IT JUST DOESN'T LOOK GOOD THROUGH THE END OF THE WEEK FOR ANY THUNDERSTORMS. IN ADDITION TO THE DRY AIR ARRIVING WE WILL ALSO HAVE A RIDGE ALOFT AND WARM TEMPERATURES ALOFT. ALL OF THESE THINGS WILL CONTINUE TO KEEP US WARM AND MOSTLY DRY. FOR THE WEEKEND...NOT MUCH OF A CHANGE. THE RIDGE WILL STILL BE ALOFT AND THERE WILL BE ONLY ENOUGH MOISTURE TRAPPED AT THE SURFACE FOR A FEW WEAK ISOLATED THUNDERSTORMS EACH DAY. BY SUNDAY THE ECMWF AND GFS SHOW THE RIDGE RETREATING TO THE EAST...BUT THE DGEX IS SLOWER...KEEPING THE RIDGE OVER HEAD THROUGH NEXT MONDAY. DESPITE THE RIDGE MOVING EAST NONE OF THE MODELS SHOW A SURGE OF MOISTURE COMING UP OUT OF MEXICO. BY THURSDAY OF NEXT WEEK THE GFS DOES BRING A HEALTHY DOSE OF MOISTURE UP...BUT BY THEN THE ECMWF HAS BUILT A RIDGE OUT WEST SO THAT IT IS COMPLETELY OUT OF PHASE WITH THE GFS...SO CONFIDENCE IS LOW THAT WE WILL BE ABLE TO SQUEEZE MUCH MORE RAIN OUT OF THIS MONSOON SEASON. LOOKING AT THE TEMPERATURES. WELL IF YOU HAVE READ THE DISCUSSION UP TO THIS POINT YOU PROBABLY CAN GUESS WHAT OUR TEMPERATURE TREND WILL BE FOR THE NEXT SEVEN DAYS...YEP MORE ABOVE NORMAL READINGS. TEMPERATURES ON THURSDAY AND FRIDAY WILL RUN FIVE TO EIGHT DEGREES ABOVE NORMAL. MORE OF THE SAME FOR SATURDAY AND SUNDAY. SHOULD BE A NICE WEEKEND. ON MONDAY THE GFS MOS GUIDANCE DROPS OUR HIGHS A FEW DEGREES BELOW NORMAL...BUT NOTHING INDICATES WHY THAT WOULD HAPPEN SO FOR MONDAY AND TUESDAY WE WILL SEE MORE HIGHS RUNNING FOUR TO SEVEN DEGREES ABOVE NORMAL. THE LONG WARM SUMMER LOOKS TO CONTINUE. && .AVIATION...VALID 16/00Z-17/00Z... VFR CONDS EXPECTED THRU PD. ISOLD 5SM TSRA MAINLY EAST OF KELP POSSIBLE THROUGH 03Z. FEW-SCT120-150 AFT 18Z WITH ISOLD 5SM TSRA EXPECTED AGAIN EAST OF EL PASO COUNTY. && .FIRE WEATHER... DRIER AIR WILL BE PUSHING FURTHER EASTWARD TONIGHT AND THURSDAY WHICH WILL LIMIT MOST THUNDERSTORM ACTIVITY TO THE SACRAMENTO MOUNTAINS AND HUDSPETH COUNTY. ON FRIDAY...UPPER RIDGE WILL BECOME ESTABLISHED OVER FAR EASTERN TEXAS AND SLOWLY MOVE EASTWARD INTO THE SOUTHEAST U.S. FOR EARLY NEXT WEEK. THIS WILL SETUP A SOUTHEASTERLY FLOW ACROSS THE AREA AND BRING LOW LEVEL MOISTURE BACK INTO FAR WEST TEXAS AND SOUTHERN NEW MEXICO. SINCE MOISTURE WILL BE FAIRLY SHALLOW AND WITH WARM TEMPERATURES ALOFT...THUNDERSTORM ACTIVITY WILL REMAIN VERY ISOLATED THROUGH EARLY NEXT WEEK. HIGH TEMPERATURES WILL REMAIN AROUND 90 FOR THE LOWLANDS THROUGH THE PERIOD. && && .PRELIMINARY POINT TEMPS/POPS...
