AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
230 PM MST MON JUL 14 2008

.SYNOPSIS...PLENTY OF MOISTURE FOR A DAILY CHANCE OF SHOWERS AND
THUNDERSTORMS IN SOUTHEAST ARIZONA THIS WEEK.

&&

.DISCUSSION...MORE SUNSHINE TO START THE MORNING THAN RECENT
DAYS...MOST DEBRIS CLOUD IS ACROSS NORTHERN COUNTIES. 12Z KTUS
SOUNDING SIMILAR WITH PRECIPITABLE WATER AT 1.83 SO PLENTY WET. RAIN
COOLED FROM PLENTY OF PRECIP COVERAGE YESTERDAY AND SLIGHT WARMING
AROUND H5 SO WE HAD TO WORK A LITTLE LONGER TO GET CONVECTION GOING
TODAY...BUT WE WERE FIRING BY 10 AM ANYWAY. HEAVY RAIN ONCE AGAIN
THE MAIN CONCERN...BUT ISOLATED WET MICROBURSTS NOT HARD TO
VISUALIZE. STRONG WAVE THAT WAS PUSHING THROUGH SOUTHERN SONORA AND
THE GULF NOW ON THE OTHER SIDE OF BAJA AND PUSHING OUT INTO THE
PACIFIC...PERHAPS LESS FOCUS TODAY BEHIND THIS...BUT THERE ARE LOTS
OF WIGGLES AND WEAKNESSES IN THE FLOW IN PLACE AND UPPER LEVEL
CONDITIONS REMAIN FAVORABLE OVER THE SOUTHEASTERN PART OF THE STATE.
EARLIER UPDATE TO FORECAST WORKING OUT WELL.

THE RIDGE ORIENTATION BECOMES A LITTLE LESS FAVORABLE ON THE LARGE
SCALE THIS WEEK...WE WONT BE ABLE TO MAINTAIN THIS LEVEL OF
MOISTURE FOREVER...BUT AT THE SAME TIME WE ARE PROBABLY BEING TOO
AGGRESSIVE WITH OUR TREND TOWARD LESS CONVECTION.

&&

.AVIATION...EXPECT SCATTERED SHOWERS AND THUNDERSTORMS MAINLY DURING
THE AFTERNOON AND EARLY NIGHTTIME HOURS INTO TUESDAY. CLOUD DECKS
WILL GENERALLY BE 4-7K FT AGL...WITH LOWER CEILINGS IN HEAVY RAIN.
VISIBILITIES AT TIMES WITH THE STRONGEST STORMS AS LOW AS 1 MILE
OBSCURING MOUNTAINS. AVIATION DISCUSSION NOT UPDATED FOR TAF
AMENDMENTS.

&&

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