AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
939 PM MST TUE JUN 27 2006

.SYNOPSIS...EAST TO SOUTHEAST FLOW WILL CONTINUE TO BRING MOISTURE
INTO THE AREA AS HIGH PRESSURE NORTHWEST OF ARIZONA SHIFTS TO THE
EAST. THE MOISTURE WILL COMBINE WITH DAYTIME HEATING TO PRODUCE
MAINLY AFTERNOON AND EVENING THUNDERSTORMS THROUGH THE WEEK.
&&

.DISCUSSION...ALTHOUGH THUNDERSTORM ACTIVITY WAS SLOW TO GET STARTED
THIS AFTERNOON...RADAR REFLECTIVITIES HAVE TRENDED STRONGER DURING
THE PAST COUPLE OF HOURS...ESPECIALLY FROM TUCSON WEST. THIS IN PART
DUE TO THE STRONG OUTFLOW THAT PUSHED OFF OF THE RIM...THROUGH
PHOENIX AND INTO THE LOWER DESERTS. THIS OUTFLOW NOT ONLY CONTINUES
TO INTERACT WITH A BOUNDARY EXTENDING AWAY FROM A STRONG STORM
SYSTEM IN NORTHERN MEXICO...BUT SOME ELEVATED ENERGY ASSOCIATED WITH
AN UPPER DISTURBANCE OVER SONORA MEXICO. IN FACT...THIS DISTURBANCE
IS RESPONSIBLE FOR THE STRONG CLUSTER OF STORMS ACROSS NW MEXICO
THIS EVENING. ALTHOUGH ENERGY FROM THIS SYSTEM WILL CONTINUE TO
SHEAR OUT TOWARDS THE EAST TONIGHT ACROSS NORTHERN SONORA...THE
NORTHERN EXTENT OF THIS SYSTEM WILL NUDGE NORTHWARD INTO THE SRN
ZONES OVERNIGHT. THEREFORE...EXPECT SCATTERED THUNDERSTORMS TO
CONTINUE WEST OF TUCSON THROUGH MIDNIGHT...WITH A SLIGHT CHANCE OF
THUNDERSTORMS ACROSS THE ENTIRE FORECAST AREA AFTER MIDNIGHT.
&&

.FIRE WEATHER...HIGH PRESSURE WILL REMAIN NORTH OF ARIZONA THIS
WEEK...CONTINUING THE EAST AND SOUTHEAST FLOW ALOFT. SUFFICIENT
MOISTURE ACROSS THE FORECAST AREA...COMBINED WITH DAYTIME HEATING
WILL RESULT IN MAINLY AFTERNOON AND EVENING THUNDERSTORMS. EXPECT
STRONG...ERRATIC AND GUSTY WINDS WITH ANY THUNDERSTORM DEVELOPMENT.
WITH THE INCREASING MOISTURE...RELATIVE HUMIDITIES WILL CONTINUE TO
MODERATE...WITH NIGHTTIME RECOVERIES GENERALLY IN THE GOOD RANGE.

&&

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