The episode as NWS TWC wrote it up.
Hurricane Marie tracked west of Baja California and out to sea, but resulted in a southeast flow of moisture into southeast Arizona. Morning surface dew points were in the 60s to near 70, with precipitable water amounts of 1.5 to 1.8 inches. Pima and Pinal Counties received the majority of the heavy rainfall and flash flooding.

NWS Tucson, AZ wrote its last area forecast discussion before the first event at Aug 25, 2:43 PM MST, 17 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE TUCSON AZ 243 PM MST MON AUG 25 2014 .SYNOPSIS...A SIGNIFICANT CHANGE IN THE WEATHER PATTERN WILL TAKE PLACE THROUGH TUESDAY AS DEEPER MOISTURE MOVES BACK INTO ARIZONA. THIS WILL RESULT IN SHOWERS AND THUNDERSTORMS...SOME WITH VERY HEAVY RAINFALL...THROUGH TUESDAY. IMPROVING WEATHER CAN BE ANTICIPATED WEDNESDAY...WITH DAYTIME TEMPERATURES REBOUNDING TO SLIGHTLY ABOVE NORMAL READINGS BY THE WEEKEND. && .DISCUSSION...CONVECTION...HEAVY RAIN AND SOME FLASH FLOODING ONGOING ACROSS SOUTHEAST ARIZONA. THE RAIN RATES IN THESE STORMS ARE IMPRESSIVE...WITH SOME RAIN GAUGES REPORTING UP TO ONE INCH RAIN TOTALS IN 15 TO 30 MINUTES. STORM TOPS SO FAR HAVE BEEN RELATIVELY LOW...WITH THE STRONGEST STORM CORES BELOW 20 KFT. SO THE PRIMARY THREAT FOR THE NEXT 24 TO 48 HOURS IS HEAVY RAIN BUT A STRONGER STORM MAY KICK OUT SOME INTENSE WINDS. THE GOOD FOLKS AT NESDIS POINTED OUT TODAY THAT THE MOIST AIR IN PLACE CURRENTLY OVER SE ARIZONA IS LIKELY FROM THE REMNANTS OF HURRICANE LOWELL AND NOT HURRICANE MARIE WHO IS SITTING OFF THE BAJA PENINSULA SEVERAL HUNDRED MILES TO THE SOUTH OF AZ. REGARDLESS OF THE SOURCE...THE AIR IN PLACE RIGHT NOW WILL ONLY BECOME MORE SATURATED WHEN THE DEEPER MOISTURE FROM MARIE FINALLY WORKS INTO SE ARIZONA TONIGHT AND TUESDAY. THE BOTTOM LINE...THE FLASH FLOOD THREAT IS LIKELY TO EXTEND WELL INTO TUESDAY...BUT WE DECIDED TO SET AN END TIME ON THE FLASH FLOOD WATCH TO 18Z TO AVOID ISSUING A TWO DAY WATCH. THINKING THE MAIN THREAT AREA TUESDAY WILL SHIFT TOWARD THE NORTHERN ZONES...GRAHAM AND GREENLEE COUNTIES...WHERE THEIR WILL BE BETTER UPPER SUPPORT FROM THE TAIL END OF AN UPPER TROUGH. I AM ALSO CONCERNED THAT THE SEVERE THREAT MAY INCREASE TOMORROW DUE TO THE COOLER AIR ALOFT AND STRONGER UPPER JET PUSHING ACROSS THE NORTHERN ZONES. THE LIMITING FACTOR WILL BE THE ABUNDANT CLOUD COVER AND LIMITED HEATING. MODELS THEN SHOW RAPID DRYING STARTING WEDNESDAY WITH CONTINUED DRYING THURSDAY. POP TRENDS ADEQUATELY SHOW THIS DOWNTURN IN PRECIP CHANCES. IN ADDITION...THE WARM AIR WILL RETURN WITH THE DRYING SO TEMPS WILL RISE BACK TO NORMAL OR EVEN SLIGHTLY WARMER THAN NORMAL BY LATE IN THE WEEK. JJB && .AVIATION...VALID THRU 26/18Z. AREA SPLIT BETWEEN HURRICANE MARIE TO THE SOUTH AND A DIGGING UPPER TROUGH TO THE NORTH. THE LATER WILL KEEP PUMPING CIRRUS LEVEL CLOUDS INTO THE AREA...WHILE THE FORMER WILL PUMP IN LOW/MID LEVEL MOISTURE IN. ENOUGH MOISTURE IN PLACE FOR SCT -SHRA THIS AFTERNOON. POINT SOUNDINGS SHOW LOWEST 5-8 KFT REMAINING DRY THOUGH WHICH SUPPORTS SOME GUSTY OUTFLOW WINDS EVEN THOUGH FLOW ALOFT REMAINS WEAK. THE GENERAL LACK OF STORM MOTION WILL HELP SATURATE THE COLUMN EARLY SO THIS THREAT WILL LESSEN LATER IN THE PERIOD. ALSO...EXPECT DEEPER MOISTURE TO SLOW WORK INTO THE AREA WHICH WILL CONTRIBUTE AS WELL. THE SLOW STORM MOTION AND FAIRLY TROPICAL NATURE OF THE AIRMASS WILL SUPPORT MVFR-IFR CONDITIONS NEAR THE STRONGER SHOWERS. HAVE REMOVED THE TS MENTION FROM ALL TERMINALS AS TIMING AND CONFIDENCE IS TOO LOW TO SUPPORT GIVEN THE LACK OF ELEVATED INSTABILITY. NEVERTHELESS...ISOLATED TS DEVELOPMENT WILL BE POSSIBLE ACROSS THE AREA BUT CAN'T PIN POINT DEVELOPMENT NEAR THE TERMINALS. AVIATION DISCUSSION NOT UPDATED FOR TAF AMENDMENTS. && .FIRE WEATHER...DEEPER MOISTURE WILL CONTINUE TO SETTLE IN ACROSS AREA TODAY AS MOISTURE FROM HURRICANE MARIE SURGES NORTHWARD. THIS AFTERNOON THERE WILL BE SOME POTENTIAL FOR GUSTY OUTFLOW WINDS AS LOW LEVEL WILL REMAIN RELATIVELY DRY...THOUGH THIS WILL DIMINISH LATER IN THE EVENING AS COLUMN BECOMES SATURATED. LIGHTNING ACTIVITY CONTINUES TO LOOK FAIRLY LIMITED. STORM MOTION WILL BE FAIRLY SLOW SO GIVEN THIS AND THE DEEP MOISTURE EXPECTED THIS LOOKS TO BE A GOOD CHANCE FOR WETTING RAINS ACROSS THE AREA. CONFIDENCE IN WHEN THE MOISTURE/SHOWERS WILL ERODE REMAINS LOW...BUT SHOULD SEE DRY CONDITIONS AGAIN LATE WEDNESDAY AS THE UPPER TROUGH DIGGING ACROSS THE WRN CONUS SLIDES THROUGH THE REGION. THIS WILL ALLOW TEMPS TO CLIMB BACK TO NEAR NORMAL BY THE END OF THE MONTH. && VISIT US ON FACEBOOK...TWITTER...YOUTUBE...AND AT WEATHER.GOV/TUCSON
