IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.

.DISCUSSION...
MID-LEVEL MOISTURE PLUME HAS BEEN PUSHED WEST OF THE RIO GRANDE
THIS MORNING...BUT MID-LEVEL RIDGE CENTERED OVER THE TX PANHANDLE
CONTINUES TO PULL MOISTURE UP INTO THE GILA.  AN UPPER LEVEL WAVE
HIGH ALOFT OVER SOUTHERN SONORA WILL CURVE NORTHWARD INTO SE ARIZONA
OVERNIGHT.  THIS FEATURE...ALONG WITH TYPICAL TERRAIN INFLUENCES...
WILL HELP INITIATE SCATTERED SHOWERS AND THUNDERSTORMS INTO THE
EVENING ACROSS THE GILA.  SLIGHTLY WARM AIR ALOFT WILL LIMIT THE
CLOUD TOPS AND RESULT IN A FAIRLY LOW LEVEL OF LIGHTNING ACTIVITY
THROUGH THIS EVENING....SIMILAR TO THE STORMS YESTERDAY.  ALTHOUGH
LOW LEVEL WINDS WILL GENERALLY BE LIGHT OUT OF THE SOUTHEAST...
SHOWERS AND STORMS WILL TEND TO DISRUPT THE FLOW ON THE LOCAL
SCALE...RESULTING IN PERIODIC WIND SHIFTS AND NEAR CALM PERIODS.
THE POTENTIAL FOR STRONG THUNDERSTORM GUSTS APPEARS MINIMAL AT
THIS TIME...BUT LOCAL GUSTS UP TO 25 MPH WILL BE POSSIBLE.  EXPECT
A SLIGHT DECREASE IN COVERAGE TOMORROW AS THE MOISTURE SHIFTS EVEN
CLOSER TO THE AZ BORDER...BUT AN UPSWING IN THUNDERSTORM ACTIVITY
MAY ARRIVE BY SUNDAY.
