AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TUCSON AZ 855 AM MST TUE SEP 12 2006 .SYNOPSIS...A LOW PRESSURE SYSTEM OVER NORTHERN BAJA WILL MOVE NORTHEAST ACROSS SOUTHEAST ARIZONA THROUGH WEDNESDAY. THIS WILL RESULT IN SCATTERED SHOWERS AND THUNDERSTORMS INTO WEDNESDAY. AS THE LOW PRESSURE SYSTEM SLOWLY DEPARTS THE AREA STARTING THURSDAY...MUCH DRIER AIR WILL OVERSPREAD SOUTHEAST ARIZONA BY THIS WEEKEND. && .DISCUSSION...ACTIVE MORNING ALREADY UNDERWAY WITH KEMX WSR-88D DETECTING SCATTERED THUNDERSTORM ACTIVITY GENERALLY ON A LINE FROM TUCSON EASTWARD. THESE THUNDERSTORMS ARE DEVELOPING IN SOUTHERLY FLOW ALOFT IN AN AREA OF STRONG DIVERGENCE EAST OF THE CLOSED MID/UPR LOW NOW ACROSS SWRN AZ/NRN MEXICO. 12Z KTUS SOUNDING SHOWS PW VALUES AROUND ONE INCH AS THE LOWER LEVELS ARE STILL RELATIVELY DRY. HOWEVER...WE EXPECT THE PW TO INCREASE THROUGH THE DAY AS SOUTHEAST LOW LEVEL FLOW CONTINUES TO TRANSPORT MORE MOISTURE NORTH FROM MEXICO. THE SOUNDING IS FAVORABLE FOR ADDITIONAL DEVELOPMENT OF THUNDERSTORMS WITH MODIFIED SOUNDING YIELDING A CAPE OF 1300 J/KG WITH A TEMP OF 93F AND DEWPOINT OF 55F. GIVEN THE STRONG UPDRAFTS EXPECTED AND 30-40KTS OF 0-6KM SHEAR TODAY SOME OF THESE STORMS SHOULD BE SEVERE WITH STRONG WINDS AND LARGE HAIL. WE WILL BE RELEASING A SPECIAL 18Z SOUNDING TODAY TO MONITOR THE INCREASE IN LOW LEVEL MOISTURE. GIVEN THE NATURE THIS MORNING FOR THE STORMS TO BE TRAINING IN THE SOUTHERLY FLOW ALOFT FROM TUCSON EASTWARD...THE SLOW EASTWARD MOVEMENT OF THIS MID/UPR LEVEL LOW AND THE ANTICIPATED INCREASE IN MOISTURE WE ARE CONSIDERING ISSUING A FLASH FLOOD WATCH FOR PORTIONS OF THE CWA LATER THIS MORNING. HOWEVER...ONCE AGAIN THE LOWER LEVEL MOISTURE AND PW INCREASE IS CRUCIAL FOR THE DEVELOPMENT OF WIDESPREAD HEAVY RAINFALL. WE PREFER TO WAIT UNTIL THE 18Z SOUNDING COMES IN TO GET A BETTER HANDLE ON THIS. THE MID/UPR LEVEL LOW WILL CONTINUE TO IMPACT SOUTHEAST ARIZONA DURING THE DAY WEDNESDAY WITH A CONTINUATION OF SHOWERS AND THUNDERSTORMS. && .AVIATION...TAFS AND TWEBS ADEQUATELY COVER ALL SIGNIFICANT WEATHER AT KTUS. && .TWC WATCHES/WARNINGS/ADVISORIES...NONE. && WEATHER.GOV/TUCSON
