Area forecast discussion, Jul 7, 2:33 PM MST, 3 hours 22 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
233 PM MST MON JUL 7 2014

.SYNOPSIS...A WEAK DISTURBANCE WILL HELP ENHANCE THE RAIN CHANCES
WITH ELEVATED THUNDERSTORM ACTIVITY THROUGH TUESDAY. SOME STORMS
WILL GENERATE HEAVY RAINFALL AND GUSTY WINDS. THEREAFTER...WE SHOULD
KEEP ENOUGH MOISTURE IN THE AREA FOR A CHANCE OF THUNDERSTORMS INTO
NEXT WEEKEND.

&&

.DISCUSSION...A WEAK DISTURBANCE WAS HELPING TRIGGER THUNDERSTORMS
TODAY AS THE AIR MASS OVER SOUTHEAST ARIZONA REMAINED VERY MOIST.
THE STORMS HAD DEVELOPED RATHER EARLY IN THE DAY WITH HEAVY
DOWNPOURS AND LOCALIZED FLOODING BEING THE MAIN CONCERN. THE STORMS
WILL CONTINUE TO TRACK SOUTHWARD THROUGH THE EVENING. MODELS SHOWED
THE DISTURBANCE ROTATING THROUGH NORTHERN MEXICO AROUND THE BASE OF
THE UPPER HIGH CENTERED OVER UTAH TONIGHT INTO TUESDAY. THAT
SAID...THIS FEATURE WILL CONTINUE TO AFFECT THE AREA WITH LINGERING
SHOWERS AND THUNDERSTORMS EXPECTED TONIGHT INTO TUESDAY.
THEREAFTER...THE TREND IN THUNDERSTORM ACTIVITY SHOULD BE DOWN A BIT
COMPARED TO TODAY AND TUESDAY AS THE INFLUENCE OF THIS DISTURBANCE
LESSENS. MODELS SUGGEST THAT THE FLOW PATTERN WILL BECOME MORE
FAVORABLE FOR ELEVATED THUNDERSTORM ACTIVITY STARTING THIS WEEKEND
INTO EARLY NEXT WEEK.

&&

.AVIATION...VALID THRU 09/00Z.  SCTD SHRA/TSRA THRU 08/04Z WITH LCL
MVFR CONDS NR +TSRA.  CLOUD BASES MOSTLY 7-11 KFT AGL WITH LCLY LWR
CONDS NEAR +TSRA.  SURFACE WINDS MOSTLY LESS THAN 10 KTS...EXCEPT TO
35 KTS NR TSRA OUTFLOWS.  ISOLD SHRA/TSRA THRU TONIGHT INCREASING TO
SCTD COVERAGE AGAIN AFT 08/19Z.  AVIATION DISCUSSION NOT UPDATED FOR
TAF AMENDMENTS.  CERNIGLIA

&&

.FIRE WEATHER...VERY ACTIVE CONVECTION THIS EVENING AND AGAIN
TUESDAY WITH SCATTERED TO WIDESPREAD SHOWERS AND THUNDERSTORMS
ACROSS SOUTHEAST ARIZONA.  LOCALIZED HEAVY RAINS ARE EXPECTED WITH
THE STORMS DUE TO THE MOIST ATMOSPHERE AND SLOW STORM MOTION.
TUESDAY HAS A BETTER THREAT OF STRONG GUSTY OUTFLOWS.  THE DAILY
CYCLE OF SHOWERS AND THUNDERSTORMS WILL BE AROUND WEDNESDAY INTO
NEXT WEEKEND...WITH A SLIGHT DOWNTURN THURSDAY AND FRIDAY AND UPWARD
TREND THIS WEEKEND.  WINDS THROUGH THE NEXT SEVEN DAYS WILL BE
GENERALLY LESS THAN 15 MPH WITH THE EXCEPTION OF STRONG GUSTY
OUTFLOW WINDS UNDER AND AROUND ANY THUNDERSTORMS.  CERNIGLIA

.TWC WATCHES/WARNINGS/ADVISORIES...NONE.
