AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
245 PM MST MON JUL 13 2015

.SYNOPSIS...EXPECT SOME STORMS TO LAST INTO THE OVERNIGHT HOURS
TONIGHT...OTHERWISE ADEQUATE MOISTURE WILL MAINTAIN A CHANCE OF
MAINLY AFTERNOON AND EVENING THUNDERSTORMS THIS WEEK. ADDITIONAL
MOISTURE FROM HURRICANE DOLORES WILL LIKELY ENHANCE RAINFALL CHANCES
BY SATURDAY. NEAR NORMAL DAYTIME TEMPERATURES WILL PREVAIL THROUGH
THURSDAY FOLLOWED BY RELATIVELY COOLER TEMPERATURES FRIDAY INTO
SUNDAY.

&&

.DISCUSSION...STILL A MOIST SOUTHERLY FLOW IN PLACE ACROSS SOUTHEAST
ARIZONA...ALTHOUGH WE'RE STARTING TO VEER A LITTLE IN MID LEVELS
WITH A WESTERLY COMPONENT CREEPING IN. H7 AND BELOW KEEPING UP WITH
THE MOISTURE NICELY AND IMMEDIATELY UPSTREAM FROM THE SOUTHWEST IS
STILL MOIST FOR NOW. STILL SEEING PRECIPITABLE WATER VALUES IN THE
1.1 TO 1.4 INCH RANGE.

WE HAVE HAD MORE CONVECTIVE INHIBITION TO OVERCOME TODAY ALONG WITH
A LITTLE WEAKER SHEAR. THIS HAS KEPT THE STORMS GENERALLY HUGGING
THE MOUNTAINS SO FAR. WITH CIRRUS SHIELDS CUTTING OFF HEATING IN
MANY LOCATIONS BEFORE THE CONVECTIVE INHIBITION CAN BE OVERCOME WE
MAY END UP WITH LESS VALLEY COVERAGE. THAT WILL LEAVE ELEVATED
UNTAPPED CONVECTIVE POTENTIAL LATER THIS AFTERNOON AND THIS
EVENING...VULNERABLE TO ANY WEAK IMPULSE OR OUTFLOW THAT COMES
ALONG. ALL HOPE IS NOT GONE FOR VALLEYS IN THE NEXT COUPLE OF HOURS
AS WE WATCH THE UNORGANIZED OUTFLOWS FROM HIGHER TERRAIN. THAT ALSO
BRINGS US TO THE ACTIVITY IN NORTHERN SONORA WHICH IS STILL EXPECTED
TO EXERT INFLUENCE INTO OUR AREA IN THE FORM OF OUTFLOWS AND A
REMNANT WEAKENING MESOSCALE CONVECTIVE CIRCULATION DUE SOUTH OF
COCHISE COUNTY. WITH THIS IN MIND WE WILL KEEP THE CHANCE OF PRECIP
GOING LATER INTO THE OVERNIGHT HOURS TONIGHT.

EVEN AS WE GAIN THE MID LEVEL WESTERLY COMPONENT THE NEXT COUPLE OF
DAYS...WE SHOULD STILL HAVE ENOUGH MOISTURE FOR A CHANCE OF SHOWERS
AND THUNDERSTORMS...ESPECIALLY NEAR THE INTERNATIONAL BORDER AND
MOUNTAIN LOCATIONS.

DOLORES IS NOW A HURRICANE ABOUT 190 MILES SOUTHWEST OF MANZANILLO
MEXICO...AND IS EXPECTED TO BECOME A MAJOR HURRICANE ON WEDNESDAY AS
SHE PUSHES TO A POSITION ABOUT 150 MILES SOUTH OF THE BAJA
PENINSULA. POSITIONING WILL BE GREAT TO HELP (ALONG WITH FAVORABLE
LARGE SCALE FEATURES) PUSH ANOTHER LONG FETCH OF DEEP MOISTURE INTO
OUR AREA BY FRIDAY AND SATURDAY. THIS WILL GIVE US AN ELEVATED
CHANCE OF SHOWERS AND THUNDERSTORMS BY SATURDAY...BUT STILL A LOT OF
DETAILS TO HAMMER OUT. RIGHT NOW SATURDAY IS LOOKING LIKE A BUSY
TIME FOR SOUTHEAST AND SOUTH CENTRAL ARIZONA.

&&

.AVIATION...VALID THRU 15/00Z.
EXPECT SCATTERED -TSRA/-SHRA ACROSS THE AREA INTO THE EVENING HOURS.
ISOLD -TSRA/-SHRA WILL THEN CONTINUE INTO TUESDAY MORNING WITH
ANOTHER INCREASING CHANCE TUESDAY AFTERNOON. BRIEF WIND GUSTS
GENERALLY AROUND 35-45 KTS WILL ACCOMPANY THE STRONGER TSRA THIS
AFTERNOON AND EARLY THIS EVENING. CLOUD DECKS WILL GENERALLY BE AT 6-
12K FT AGL WITH PLENTY OF DEBRIS CLOUD OVERNIGHT. AVIATION
DISCUSSION NOT UPDATED FOR TAF AMENDMENTS.

&&

.FIRE WEATHER...EXPECT ISOLATED TO SCATTERED SHOWERS AND
THUNDERSTORMS THIS WEEK. THE BULK OF THIS ACTIVITY WILL OCCUR DURING
THE AFTERNOON AND EVENING HOURS WHEN BRIEF GUSTY WINDS AND LOCALLY
HEAVY RAINFALL WILL BE MORE FAVORABLE. INCREASED MOISTURE FROM
TROPICAL SYSTEM DOLORES SHOULD ENHANCE RAINFALL CHANCES BY THIS
WEEKEND. OTHERWISE...GENERALLY LIGHT TERRAIN DRIVEN WINDS WILL
PREVAIL...WITH OCCASIONAL AFTERNOON GUSTS DUE TO STRONG DAYTIME
HEATING.

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