NWS Phoenix, AZ wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 31, 1:55 PM MST, 6 hours 49 minutes earlier.
Area forecast discussion, Jul 31, 1:55 PM MST, 6 hours 49 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PHOENIX AZ 155 PM MST THU JUL 31 2014 .SYNOPSIS... A LOW GRADE MONSOON EVENING IS ANTICIPATED TONIGHT WITH JUST A SLIGHT CHANCE FOR THUNDERSTORMS FORECAST OVER THE LOWER CENTRAL DESERTS. EXPECT AN UPTREND IN THUNDERSTORM CHANCES EXPANDING FROM EAST TO WEST FRIDAY THROUGH SUNDAY. ACCORDINGLY...TEMPERATURES WILL NOT BE AS HOT. BY SUNDAY HIGH TEMPERATURES IN THE CENTRAL DESERTS WILL LIKELY LOWER INTO THE 90S. NEXT WEEK...A DOWNTREND IN THUNDERSTORM CHANCES AND STEADILY WARMING HIGH TEMPERATURES IS ANTICIPATED AS DRIER AIR FILTERS IN FROM THE WEST. && .DISCUSSION... TONIGHT... UPPER HIGH REMAINS CENTERED TO OUR SOUTH NEAR THE MEXICAN BORDER THIS EVENING...ALLOWING FOR A SOMEWHAT DRIER SWLY TO WLY FLOW ALOFT TO AFFECT SRN/CENTRAL ARIZONA. AT 2 PM IR IMAGERY SHOWED CONSIDERABLE MAINLY HIGH CLOUDS ACROSS THE LOWER DESERT OF SERN CA AND ARIZONA...A RESULT OF A DECAYED CONVECTIVE COMPLEX THAT FORMED OVER NWRN MEXICO LAST NIGHT. THE CLOUDS ALONG WITH SLIGHTLY INCREASED HUMIDITY LEVELS ALLOWED TEMPERATURES TO FALL OFF SLIGHTLY COMPARED TO YESTERDAY AND THEY DROPPED BELOW EXCESSIVE HEAT WARNING THRESHOLDS. AS A RESULT THE HEAT WARNING WAS CANCELLED EARLIER THIS AFTERNOON FOR SOUTHEAST CALIFORNIA. SURFACE DEWPOINTS OVER THE LOWER DESERTS WERE RUNNING IN THE LOW TO MID 50S EARLY THIS AFTERNOON AND PWAT VALUES WERE AROUND 1.4 INCHES. WITH WEAK WIND FIELDS ALOFT... UNFAVORABLE WESTERLY STEERING FLOW AND LIMITED LOW LEVEL MOISTURE... CHANCES FOR STORMS TONIGHT OVER THE LOWER AZ DESERT ARE MEAGER. EXPECT A LOW GRADE MONSOON EVENING WITH POPS RUNNING AROUND 10-15 PERCENT UNDER PARTLY CLOUDY SKIES. FRIDAY THROUGH SUNDAY... MODEL REMAIN VERY CONSISTENT IN CALLING FOR A MARKED INCREASE IN MOISTURE DURING THE PERIOD...WITH THE FLOW BECOMING MORE CLASSICALLY MONSOONAL. STEERING FLOW CHANGES FROM WEAK WEST TO STRONGER OUT OF THE SOUTHEAST AND SOUTH...AND MOISTURE SPREADS WESTWARD ACROSS THE LOWER DESERTS WITH PWAT VALUES CLIMBING TO NEARLY 2 INCHES IN SOME LOCATIONS BY SATURDAY AFTERNOON. OF COURSE...THERE ARE MODEL DIFFERENCES REGARDING THE DISTURBANCES IN THE UPPER FLOW BUT MOST OF THE GUIDANCES SUGGEST THAT AN INVERTED TROF WILL ROTATE AROUND THE HIGH AND INTO WESTERN AZ BY SATURDAY...AND FLOW ALOFT WILL BECOME STRONGER AND MORE DIFLUENT BY THAT TIME. CAPE/INSTABILITY ALSO UPRAMPS AND CORRESPONDINGLY WE HAVE A SIGNIFICANTLY INCREASING POP TREND WITH THE HIGHEST NUMBERS FOR SATURDAY AFTERNOON AND EVENING. BY THAT TIME EXPECT 30-35 PERCENT OVER MOST OF THE LOWER DESERTS...WITH VALUES AROUND 60 PERCENT IN THE HIGHER TERRAIN EAST OF PHOENIX. INCREASING CLOUDS/MOISTURE WILL RESULT IN A SHARP DOWNTURN IN HIGH TEMPERATURES DURING THE PERIOD WITH WELL BELOW NORMAL HIGHS FORECAST FOR THE WEEKEND. BY SUNDAY...GIVEN THE EXPECTED CONVECTION OVERNIGHT ON SAT NIGHT...WE SHOULD SEE HIGHS IN THE 90S ACROSS MUCH OF THE LOWER DESERTS AND WE LOWERED THE HIGH FOR PHOENIX TO JUST 97 DEGREES. MONDAY THROUGH THURSDAY... THE FIRST HALF OF THE NEXT WORKWEEK CONTINUES TO LOOK LIKE A DOWNTREND IN STORM ACTIVITY AS THE INVERTED TROUGH DEPARTS AND DRIER AIR MOVES INTO THE REGION...AT FIRST FROM WESTERLY FLOW THEN NORTHERLY. ACCORDINGLY...POPS RETREAT EASTWARD AND TEMPS SLOWLY CLIMB. && .AVIATION... SOUTH-CENTRAL AND SOUTHWEST ARIZONA AND SOUTHEAST CALIFORNIA...INCLUDING KPHX...KIWA...KSDL...KIPL...AND KBLH... CONSIDERABLE MID AND HIGH CLOUDINESS IS EXPECTED TO CONTINUE OVER THE ENTIRE REGION THROUGH THE TAF PERIOD AS INCREASING SOUTHERLY FLOW CONTINUES TO IMPORT MOISTURE INTO THE DESERT SOUTHWEST. ALTHOUGH THUNDERSTORMS ARE NOT EXPECTED TO AFFECT THE TERMINALS AT THIS TIME...THERE IS A CHANCE THAT OUTFLOWS FROM DISTANT STORMS TO THE NORTH COULD AFFECT THE WINDS AT THE PHX AREA TERMINALS THIS EVENING...WITH OUTFLOWS FROM STORMS OVER SE AZ ENHANCING THE TYPICAL LATE-EVENING EASTERLY WINDS LATER TONIGHT. WINDS AT BOTH THE SE CA TAF SITES WILL REMAIN MOSTLY OUT OF A SOUTHERLY TO SOUTHEASTERLY DIRECTION THROUGH THE TAF PERIOD. AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS. && .FIRE WEATHER... SATURDAY THROUGH WEDNESDAY... MOISTURE WILL RETURN TO THE AREA BY THE WEEKEND WITH SHOWERS AND THUNDERSTORMS EXPECTED. DAY TO DAY TIMING AND PLACEMENT OF STORMS IS HARD TO PIN DOWN BUT IT LOOKS LIKE A DECENT CHANCE OF A WETTING RAIN EVEN ACROSS SOME DESERT LOCATIONS. HUMIDITY VALUES WILL STEADILY INCREASE WITH MINIMUM VALUES BETWEEN 20 AND 30 PERCENT EXPECTED ACROSS THE DESERTS SATURDAY INTO THE EARLY PART OF NEXT WEEK. CORRESPONDINGLY...HIGH TEMPERATURES WILL FALL OFF...DROPPING FROM AROUND SEASONAL NORMALS FRIDAY TO WELL BELOW NORMAL VALUES ON SUNDAY. SLIGHT WARMING WILL RETURN BY NEXT TUESDAY AS HUMIDITY VALUES LOWER SOMEWHAT. STRONG WINDS ARE NOT EXPECTED DURING THE FIVE DAY PERIOD...AND THEY SHOULD TYPICALLY FAVOR SOUTH TO SOUTHWEST DIRECTIONS DURING THE AFTERNOON AND EVENING HOURS. && .PSR WATCHES/WARNINGS/ADVISORIES...
