Area forecast discussion, Jul 30, 2:35 PM MST, 5 hours 59 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
235 PM MST MON JUL 30 2012

.SYNOPSIS...ENOUGH MOISTURE WILL BE AROUND THIS WEEK FOR CONTINUED
CHANCE OF MAINLY AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS.

&&

.DISCUSSION...THUNDERSTORM FREE ACROSS MOST OF SOUTHEAST ARIZONA
THIS AFTERNOON. THE EXCEPTION WERE STORMS IN WESTERN PIMA COUNTY
ASSOCIATED WITH MCV MOVING INTO SE YUMA COUNTY. EVEN MOST OF SONORA
MEXICO WAS THUNDERSTORM FREE AS BOTH AREAS HAVE SEEN SOME DRYING AND
BOTH AREAS WERE UNDER SUBSIDENCE FIELD IN WAKE OF INVERTED TROF
WHICH WAS OVER WESTERN ARIZONA THIS AFTERNOON. SURFACE DEWPOINTS
WERE MOSTLY IN THE 50S ACROSS THE AREA DOWN ACROSS SONORA MEXICO
WITH HERMOSILLO MID AFTERNOON DEWPOINT IN THE MID 50S. HOWEVER THERE
IS SOME HOPE THAT PORTIONS OF THE AREA MAY SEE STORMS TONIGHT. THAT
WOULD BE SOUTHEAST OF TUCSON WHERE APPROACHING SMALL WELL-DEFINED
INVERTED TROF WAS MOVING THROUGH NORTHERN CHIHUAHUA MEXICO. STORMS
HAVE FORMED ALONG SONORA/HERMOSILLO STATE LINE AND WERE SLOWLY
MOVING W-NW. SO FOR TONIGHT...HAVE MADE SOME ADJUSTMENTS BY HAVING
THE FOCUS FOR HIGHER POPS ACROSS COCHISE COUNTY AND WESTERN PIMA
COUNTY.

REMAINS OF INVERTED TROF WILL BE OVER WESTERN ARIZONA OVER THE NEXT
COUPLE OF DAYS...WITH ENOUGH MOISTURE AROUND TO SEE ISOLATED TO
WIDELY SCATTERED AFTERNOON/EVENING STORMS. A WEAK REFLECTION FROM
THE CHIHUAHUA INVERTED TROF MAY BE AROUND TOMORROW TO FOCUS STORMS.
PROBLEM IS WHERE WILL IT BE?

LOW END MONSOON FORECAST THU INTO THE UPCOMING WEEKEND.

HIGH TEMPERATURES WILL GRADUALLY WARM TO NEAR NORMAL LEVELS BY
WEDNESDAY AND HANG AROUND THERE IF NOT A BIT WARMER THU INTO THE
WEEKEND.

NOTE TO OUR RADAR USERS: AS OF 230 PM...THE COMMUNICATION ISSUE FOR
THE RADAR IS IN THE HANDS OF THE TELCO FOLKS. STILL NO TIMETABLE ON
WHEN THIS WILL BE RESOLVED. GOOD THING ITS A DOWN DAY ACROSS THE
AREA.

&&

.AVIATION...ISOLD TSRA/SHRA THIS EVENING. ISOLD-SCTD TSRA/SHRA DVLPG
TUE AFT 31/18Z. ERRATIC WINDS ASSOCIATED WITH THUNDERSTORMS
OTHERWISE NORMAL DIURNAL TRENDS GENERALLY LESS THAN 10 KTS. AVIATION
DISCUSSION NOT UPDATED FOR TAF AMENDMENTS.

&&

.FIRE WEATHER...NO FIRE WEATHER CONCERNS AT THIS TIME.

&&

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