AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
134 PM MST MON AUG 11 2014

.SYNOPSIS...SCATTERED MAINLY AFTERNOON AND EVENING SHOWERS AND
THUNDERSTORMS THIS WEEK. A STRONG INCREASE IN STORMS IS EXPECTED
TUESDAY AND TUESDAY NIGHT AS MOISTURE DEEPENS AND A PASSING
DISTURBANCE HELPS TO ORGANIZE STORMS. SOME STORMS WILL GENERATE
LOCALLY HEAVY RAIN AND STRONG WINDS.

&&

.DISCUSSION...RADAR WAS SHOWING A FEW THUNDERSTORMS DEVELOPING EARLY
THIS AFTERNOON. EXPECT THIS ACTIVITY TO INCREASE IN AREAL COVERAGE
THROUGH THIS EVENING BEFORE DIMINISHING LATE TONIGHT. STILL FOCUSING
ON TUESDAY INTO EARLY WEDNESDAY FOR THE BEST TIME FRAME FOR MORE
WIDESPREAD RAIN ACROSS SOUTHEAST ARIZONA. MODELS CONTINUED TO PICK
UP ON AN IMPULSE THAT WAS PROGGED TO TRACK OUT OF NORTHERN MEXICO
AND THROUGH ARIZONA TOMORROW AFTERNOON INTO EARLY WEDNESDAY MORNING.
PLENTY OF MOISTURE IN PLACE TO SUPPORT WIDESPREAD SHOWERS AND
THUNDERSTORMS WITH THE AID OF THIS FEATURE. THAT SAID...WILL
CONTINUE TO ADVERTISE RATHER HIGH POP VALUES FOR THIS TIME OF YEAR
TUESDAY AND TUESDAY NIGHT. GFS MODEL PROGGED THE IMPULSE TO EXIT
NORTHEAST ARIZONA AFTER 18Z TUESDAY. NOT SURE IF THE SUBSIDENCE
BEHIND THIS FEATURE WILL LIMIT THE AMOUNT OF THUNDERSTORM ACTIVITY
SIGNIFICANTLY ON WEDNESDAY. FOR NOW...WILL KEEP THE CURRENT POP
VALUES GOING FOR WEDNESDAY BUT MAY NEED TO ADJUST THEM DOWN A BIT
LATER. THEREAFTER...MODELS SPREAD DRIER AIR INTO THE REGION LATE IN
THE WEEK AS A SYSTEM TRACKS INTO THE NORTHERN ROCKIES. THIS WILL
RESULT IN DECREASING RAIN CHANCES BY FRIDAY. DAYTIME TEMPERATURES
WILL REMAIN NEAR NORMAL FOR THIS TIME OF YEAR...BUT A FEW DEGREES
COOLER TUESDAY AND WEDNESDAY BASED THE ANTICIPATED CLOUDINESS AND
RAIN.

&&

.AVIATION...VALID THRU 12/00Z.
SCATTERED THUNDERSTORMS THROUGH THIS EVENING...WITH CIGS 8-12K FT
AGL. STRONG GUSTY OUTFLOWS ASSOCIATED WITH THUNDERSTORMS...OTHERWISE
NORMAL DIURNAL WIND TRENDS. MORE WIDESPREAD RAIN AND SCATTERED
THUNDERSTORMS DEVELOPING TUESDAY AFTERNOON ACROSS SOUTHEAST
ARIZONA.  AVIATION DISCUSSION NOT UPDATED FOR TAF AMENDMENTS.

&&

.FIRE WEATHER...DAILY SCATTERED AFTERNOON AND EVENING SHOWERS AND
THUNDERSTORMS ARE EXPECTED THIS WEEK...WITH A PEAK IN ACTIVITY
TUESDAY. STRONG...GUSTY AND ERRATIC WINDS BETWEEN 35 AND 45 MPH ARE
