THE NATIONAL WEATHER SERVICE IN TUCSON HAS ISSUED A

* SMALL STREAM FLOOD ADVISORY FOR...
  WESTERN PIMA COUNTY IN SOUTH CENTRAL ARIZONA...
  THIS INCLUDES AREAS WEST OF SELLS...

* UNTIL 730 PM MST

* AT 532 PM MST...NATIONAL WEATHER SERVICE DOPPLER RADAR INDICATED A 
LINE OF SHOWERS AND THUNDERSTORMS MOVING TO THE WEST AT 10 TO 15 MPH 
ACROSS THE TOHONO O'ODHAM NATION. DOPPLER RADAR RAINFALL ESTIMATES 
INDICATE THAT A FEW OF THESE STORMS ARE PRODUCING HOURLY RAINFALL 
AMOUNTS IN EXCESS OF THREE INCHES PER HOUR. HOWEVER...THE RADAR 
ESTIMATES HAVE BEEN OVER ESTIMATING THE RAINFALL BASED ON A COUPLE 
OF GAUGE COMPARISONS. IN REALITY HOURLY RAINFALL AMOUNTS ARE MORE 
LIKELY IN EXCESS OF 1.5 TO 2 INCHES PER HOUR. THIS AMOUNT OF RAIN 
WILL CONTINUE TO CAUSE FLOODING CONCERNS OVER THE NEXT COUPLE OF 
HOURS. THE AREAS OF IMMEDIATE CONCERN ARE BETWEEN COWLIC...VAMORI... 
SOUTH KOMELIK...CHOULIC AND SAN MIGUEL WHERE THE HEAVIEST RAIN HAS 
FALLEN DURING THE PAST COUPLE OF HOURS. A FLASH FLOOD WARNING IS 
STILL IN EFFECT FOR THIS AREA THROUGH 630 PM MST THIS EVENING. OTHER 
AREAS OF CONCERN ARE FROM AREAS NORTH OF COWLIC TO NOLIC TO COVERED 
WELLS TO SANTA ROSA TO EAST OF VENTANA. THE HEAVY RAIN WILL CONTINUE 
TO PUSH TO THE WEST OVER THE NEXT COUPLE OF HOURS AND COULD MOVE AS 
FAR WEST AS WHY AND ALI CHUK NEAR THE INTERNATIONAL BORDER. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

EXCESSIVE RUNOFF FROM HEAVY RAINFALL WILL CAUSE ELEVATED LEVELS IN
WASHES AND STREAMS...AND PONDING OF WATER ON COUNTRY ROADS AND
FARMLAND ALONG THE BANKS OF CREEKS AND STREAMS.

DO NOT DRIVE YOUR VEHICLE INTO AREAS WHERE THE WATER COVERS THE
ROADWAY. THE WATER DEPTH MAY BE TOO GREAT TO ALLOW YOUR CAR TO CROSS
SAFELY. MOVE TO HIGHER GROUND.

A FLOOD ADVISORY MEANS RIVER OR STREAM FLOWS ARE ELEVATED OR PONDING
OF WATER IN URBAN OR OTHER AREAS IS OCCURRING OR IS IMMINENT.

Area forecast discussion, Jul 12, 2:00 PM MST, 3 hours 41 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
200 PM MST THU JUL 12 2012

.SYNOPSIS...ENOUGH MOISTURE FOR ISOLATED TO SCATTERED AFTERNOON AND
EVENING THUNDERSTORMS INTO NEXT WEEK.

&&

.DISCUSSION...NO SURPRISES SO FAR THIS AFTERNOON. WESTERN AREAS HAVE
BEEN SLOW TO HEAT UP THROUGH THE DECAYING DEBRIS CLOUD. MUCH BETTER
SOLAR INSOLATION IN FAR EASTERN AREAS BUT ALSO NOT AS WET AND 12K
KTUS SOUNDING WAS SHOWING H5 TEMPERATURES NEAR -5C...A TOUCH WARMER
THAN YOU WANT FOR GOOD CONVECTION. SO FAR THIS HAS PROVED FAIRLY
ACCURATE AS OF 2 PM WITH ONLY ISOLATED CONVECTION MAINLY SOUTH AND
WEST OF TUCSON METRO AREA. THE NICE MOISTURE GRADIENT THROUGH
EASTERN PIMA...SANTA CRUZ AND WESTERN COCHISE COUNTY (GOES SOUNDER
ESTIMATES IN THE 1.5 TO 1.6 RANGE NEAR EASTERN PIMA DOWN TO ABOUT AN
INCH IN NEW MEXICO) HAS INDEED BEEN A FOCUS FOR INITIAL THUNDERSTORM
DEVELOPMENT AS EXPECTED...BUT MODEST MID LEVEL TEMPERATURES COMBINED
WITH CONTINUED DRYING IN EASTERLY FLOW HASN'T BROUGHT MUCH MORE TO
VALLEY LOCATIONS THAN RECENT DAYS.

AS THE RIDGE PHASES EASTWARD WE SHOULD SEE MORE COVERAGE THROUGH
EASTERN ZONES OVER THE NEXT 72 HOURS. STILL EMPHASIZING WESTERN
AREAS FRIDAY...BUT SATURDAY AND SUNDAY WILL SEE ADDITIONAL
DEVELOPMENT FURTHER EAST. HOWEVER...THE ORIENTATION OF THE RIDGE AS
THE TROUGH DIGS INTO THE PACIFIC NORTHWEST MAY STILL SEE RELATIVELY
WARM MID LEVELS AND WEAKER FLOW IN THE SOUTHEAST CORNER OF THE STATE.

STILL THINKING THAT LARGE SCALE FEATURES WILL MAKE WAY FOR STRONG
DISTURBANCES ROTATING UNDER THE RIDGE IN AN INCREASING SOUTHEASTERLY
AND SOUTHERLY FLOW NEXT WEEK. LONG FETCH OF DEEP MOISTURE WITH
INVERTED TROUGH APPROACHING THE AREA MONDAY AND TUESDAY.

&&

.AVIATION...SCT-BKN CLOUDS AT 6-9K FT AGL WITH SCT TSRA/SHRA
DEVELOPING MAINLY NEAR AND WEST OF A KFHU...TO KTUS...TO KCGZ LINE.
WIND GUSTS TO 45 KTS AND MVFR CIGS/VSBYS IN THE VICINITY OF
STRONGEST TSRA. DIMINISHING TSRA CHANCES AFT 13/05Z AND IMPROVING
CEILINGS. SELY/SLY SURFACE WIND AT 10-15 KTS THRU 13/02Z...WITH SOME
AFTERNOON AND EARLY EVENING GUSTS AROUND 20 KTS. SURFACE WIND
GENERALLY LESS THAN 10 KTS AFT 13/04Z. AVIATION DISCUSSION NOT
UPDATED FOR TAF AMENDMENTS.

&&

.FIRE WEATHER...THERE WILL BE A CHANCE OF SHOWERS AND THUNDERSTORMS
THE NEXT SEVEN DAYS...MAINLY DURING THE AFTERNOON AND EVENING HOURS.
STRONG...ERRATIC AND GUSTY WINDS WILL BE POSSIBLE WITH ANY OF THE
THUNDERSTORMS. EXPECT BREEZY AND GUSTY WINDS DURING THE AFTERNOON
AND EARLY EVENING HOURS DUE TO STRONG HEATING...AND MAINLY LIGHT
WINDS DURING THE OVERNIGHT AND EARLY MORNING HOURS.

&&

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