AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
150 AM MST THU JUN 11 2009

.SYNOPSIS...DRY CONDITIONS WITH GUSTY WINDS AT TIMES AND A SLOW
WARMING TREND AS WE REMAIN BETWEEN HIGH PRESSURE OVER MEXICO AND LOW
PRESSURE TO THE NORTHWEST.

&&

.DISCUSSION...PATCHES OF HIGH AND MID CLOUD IN AN OTHERWISE DRY
WESTERLY TO SOUTHWESTERLY FLOW. SURFACE DEWPTS BACK DOWN INTO THE
20S WITH PRECIPITABLE WATER VALUES BACK UNDER 1/2 INCH AS PER UPPER
AIR SOUNDINGS AND GOES SOUNDER ESTIMATES.

THE PATTERN SHOULD PERSIST INTO AT LEAST EARLY NEXT WEEK AS A STRONG
RIDGE REMAINS ORIENTED FROM CENTRAL MEXICO THROUGH TEXAS AND THE
GULF OF MEXICO WHILE THE MEAN TROUGH POSITION REMAINS ANCHORED NEAR
THE PACIFIC NORTHWEST AND OTHER HIGHER LATITUDE WESTERN STATES. THE
ENHANCED GRADIENT WILL BRING GUSTY WINDS AT TIMES...SUCH AS THIS
AFTERNOON. ULTIMATELY THE HIGH WILL PHASE FURTHER EASTWARD AND ALLOW
SOME ENERGY TO AGAIN CARVE A LITTLE FURTHER SOUTH AND EAST. THIS
WOULD DRAW MOISTURE NORTHWARD AND BRING A CHANCE OF CONVECTION TO
THE AREA...BUT THE EARLIEST WE WOULD SEE ANYTHING LIKE THAT WOULD BE
SOMETHING ON THE ORDER OF NEXT TUESDAY OR WEDNESDAY WITH A LOWER
ENERGY PATTERN IN PLACE.

BOTTOM LINE IS DRY AND GUSTY AT TIMES WITH TEMPERATURES MODERATED
BELOW MID JUNE NORMALS.

&&

.FIRE WEATHER...THE STORM SYSTEM WHICH BROUGHT PRECIPITATION TO THE
AREA CONTINUES TO MOVE EAST OF THE REGION...AND A DRY SOUTHWESTERLY
FLOW CAN BE EXPECTED IN ITS WAKE. LOWER AFTERNOON RELATIVE
HUMIDITIES ARE FORECAST THE NEXT COUPLE OF DAYS...AS WELL AS GUSTY
SOUTHWEST WINDS DURING THE AFTERNOON/EARLY EVENING HOURS THROUGH THE
UPCOMING WEEKEND. BECAUSE OF THE STRONGER WINDS AND LOW
HUMIDITIES...CRITICAL FIRE WEATHER CONDITIONS ARE EXPECTED ACROSS
SOUTHERN PORTIONS OF FIRE WEATHER ZONE 148 INCLUDING SANTA CRUZ AND
COCHISE COUNTIES...WITH A RED FLAG WARNING IN EFFECT BETWEEN NOON
AND 7 PM MST TODAY.

&&

.AVIATION...EXPECT BROKEN-OVERCAST CLOUDS AT OR ABOVE 15K FT AGL
INTO THURSDAY. WITH SOUTHEAST ARIZONA IN BETWEEN HIGH PRESSURE TO
THE SOUTHEAST AND LOW PRESSURE TO THE NORTHWEST EXPECT GUSTY WINDS
TO DEVELOP THIS AFTERNOON...SURFACE WINDS DURING THE 16Z-23Z PERIOD
SWLY/WLY 10- 20 KTS WITH GUSTS OF 20-30 KTS. AVIATION
DISCUSSION NOT UPDATED FOR TAF AMENDMENTS.

&&

.TWC WATCHES/WARNINGS/ADVISORIES...RED FLAG WARNING FOR SOUTHERN
