AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
145 PM MST SUN AUG 13 2006

.SYNOPSIS...A MOIST AND UNSTABLE AIRMASS WILL REMAIN OVER SOUTHEAST
ARIZONA FOR CONTINUED THUNDERSTORM ACTIVITY THIS WEEK.

&&

.DISCUSSION...LARGE COMPLEX FROM NORTHERN SONORA FED DEBRIS CLOUD
AND MOISTURE INTO SOUTHEAST ARIZONA WITH MULTIPLE OUTFLOWS EARLIER
TODAY. 12Z KTUS SOUNDING CAME IN WITH A HEALTHY 1.6 INCHES
PRECIPITABLE WATER AND PLENTY UNSTABLE. SOME LOW LEVEL SHEAR BUT
WINDS ARE QUITE LIGHT AT STEERING LEVELS. SCATTERED CONVECTION HAS
HAD NO PROBLEM FROM THE MORNING HOURS ON. VERY SLOW MOVEMENT WITH
TRAVEL MAINLY BASED ON REBUILDING THROUGH DISCONTINUITIES AND
FOLLOWING MOISTURE GRADIENTS. HEAVY RAIN THE MAIN CONCERN WITH
ISOLATED WET MICROBURSTS A POSSIBILITY.

INFLUENCE OF DEVELOPING WEST COAST TROUGH SEEMS TO BE LOOSING ITS
PUNCH AT THIS LATITUDE. AREAS FROM TUCSON EAST NOT LIKELY TO SEE
MUCH IN THE WAY OF SIGNIFICANT DRYING AS WE KEEP MORE OF A SOUTHERLY
COMPONENT TO OUR FLOW...KEEPING THE DEEPER MOISTURE IN OR VERY NEAR
TO THE AREA. THE FORECAST HAS MODERATED BACK FROM THE PREVIOUSLY
EXPECTED DRYING TREND TO A MORE SEASONAL MID AUGUST FORECAST.
EASTERLY WAVE NEAR FAR SOUTHWEST TEXAS / NORTHERN MEXICO WILL HAVE
TO BE WATCHED...BUT MAY END UP PULLING UP AND AROUND THE HIGH SHORT
OF ARIZONA.

&&

.AVIATION...TAFS AND TWEBS ADEQUATELY COVER ALL SIGNIFICANT WEATHER
AT KTUS.

&&

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