AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
145 PM MST MON JUN 29 2009

.SYNOPSIS...HIGH PRESSURE ALOFT NEAR THE FOUR CORNERS REGION WILL
MAINTAIN SOUTHEASTERLY FLOW AND BRING DEEP MOISTURE INTO SOUTHEAST
ARIZONA THIS WEEK. THIS PATTERN WILL PROVIDE SCATTERED MAINLY
AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS.

&&

.DISCUSSION...CONVECTION STARTING IN ERNEST OVER THE PAST HOUR WITH
NICE ORGANIZATION ON THE RIM. LESS DEBRIS CLOUD AROUND THIS
MORNING...SO MANY AREAS WERE ABLE TO MANAGE MORE SUNSHINE TODAY.
FULL MOISTURE IN PLACE WITH SURFACE DEWPTS IN THE UPPER 50S TO
MIDDLE 60S THIS MORNING...EASILY HOLDING MIDDLE TO UPPER 50S THIS
AFTERNOON. 12Z KTUS SOUNDING CAME IN WITH 1.58 INCHES OF
PRECIPITABLE WATER WHICH IS CONSISTENT WITH THE DEEPER MOISTURE
EXTENDING UP FROM SONORA ON GOES SOUNDER ESTIMATES. LESS STABLE
TEMPERATURE PROFILE WITH A LITTLE COOLING AROUND H5 OVER THE PAST 24
HOUR4S WITH BETTER SHEAR AS WELL. LOW LEVEL SOUTHERLY PUSH TRYING TO
DEEPEN MOISTURE IN LOWER DESERT LOCATIONS. ADD IN A FAVORABLE
EASTERLY COMPONENT TO STEERING LEVEL FLOW AND IT IS STILL SHAPING UP
TO BE A MORE ACTIVE DAY WITH COVERAGE SPREADING FURTHER WESTWARD.
ANOTHER DAY WHERE LOCALLY HEAVY RAINFALL AND WET MICROBURSTS A
CONCERN.

HIGH CENTER RECONSOLIDATING TO THE NORTHEAST...SO EASTERLY AND
SOUTHERLY COMPONENTS TO FLOW SHOULD BE FAVORABLE MOST OF THE WEEK.
EXPECT A DAILY SHOT OF SCATTERED MAINLY AFTERNOON AND EVENING
SHOWERS AND THUNDERSTORMS. BOTH GFS AND ECMWF BRING IN SOME WEST
COASTAL TROFINESS THIS WEEKEND...BUT GFS SEES HIGH RECONSOLIDATE
INTO A SEMI BLOCKING POSITION THROUGH NORTHWEST AND NORTHCENTRAL
MEXICO WHILE THE EUROPEAN PHASES THE HIGH INTO THE SOUTHERN PLAINS.
THESE DIFFERENCES ARE MORE IMPORTANT FOR OTHER PARTS OF THE
STATE...NO REASON AT THIS POINT TO BACK OFF ON THE FORECAST MUCH FOR
MOST OF OUR AREA.

&&

.AVIATION...ANOTHER ROUND OF SCATTERED TSRA/SHRA IS EXPECTED THIS
AFTERNOON AND EVENING. ASSOCIATED CEILINGS WILL BE 10-13K FT AGL
WITH CIGS NEAR TSRA/SHRA DOWN TO ABOUT 3-6K FT AGL. SURFACE WINDS
TODAY GENERALLY DIURNAL IN NATURE AND LESS THAN 15 KTS...WITH THE
EXCEPTION OF ERRATIC/GUSTY OUTFLOW WINDS NEAR ANY THUNDERSTORMS.
AVIATION DISCUSSION NOT UPDATED FOR TAF AMENDMENTS.

&&

.FIRE WEATHER...A MOIST ATMOSPHERE ACROSS SOUTHEAST ARIZONA WILL
RESULT IN SCATTERED MAINLY AFTERNOON AND EVENING SHOWERS AND
THUNDERSTORMS THIS WEEK. THE HIGHER HUMIDITY AND RAINFALL
WILL RESULT IN FEW FIRE WEATHER CONCERNS.

&&

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