SUFFICIENT MOISTURE WILL BE SITUATED ACROSS THE SOUTHWEST STATES THE NEXT FEW DAYS TO WARRANT A SLIGHT CHANCE OF MAINLY AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS OVER THE LOWER DESERTS...WITH BETTER CHANCES OVER THE SOUTH-CENTRAL ARIZONA HIGHER TERRAIN. THE MAIN THREAT FROM THESE THUNDERSTORMS WILL BE LOCALLY HEAVY RAINFALL. BY THE WEEKEND...SOME DRYING IS EXPECTED TO OCCUR OVER SOUTHEAST CALIFORNIA AND FAR SOUTHWEST ARIZONA AS A SOUTHWEST FLOW OF AIR RETURNS. THIS WILL BRING AN END TO THE THUNDERSTORM THREAT OUT THERE. MEANWHILE ...MAXIMUM TEMPERATURES WILL SHOW LITTLE DAY-TO-DAY VARIATION THE ENTIRE WEEK. && .SHORT TERM... TONIGHT THROUGH FRIDAY... ISOLATED STORMS HAVE OCCURRED OVER ZONE 24 EARLY THIS AFTERNOON AND LIKELY HAVE PRODUCED LOCALLY HEAVY RAIN. STORMS ARE APT TO BECOME A BIT MORE NUMEROUS BEFORE DIMINISHING DURING THE EVENING. WESTERN PORTIONS OF THE FORECAST AREA HAVE BEEN QUIET WITH ONLY SOME MINOR CUMULIFORM CLOUD DEVELOPMENT SO FAR. HOWEVER...1Y7 SOUNDINGS HAVE SHOWN SIGNIFICANT MOISTENING DURING THE DAY TODAY SO SLIGHT CHANCE POPS IN WESTERN PORTIONS OF THE FORECAST AREA TONIGHT.

OTHERWISE...EXPECT TEMPS TO BE PRETTY CLOSE TO NORMALS. && .LONG TERM... FRIDAY NIGHT THROUGH TUESDAY... BY THE WEEKEND...EURO AND UKMET BRING IN ANOTHER RATHER STRONG TROUGH TO THE WRN US WHICH WOULD ENHANCE THE SWLYS AGAIN AND TOTALLY DRY OUT PERHAPS THE ENTIRE CWA. GFS IS MORE RELUCTANT TO DO THIS AND WILL NOT GO THAT GUNG-HO WITH DRYING AS YET...BUT WILL DROP POPS BELOW 10 PERCENT WRN CWA OVER THE WEEKEND.
