AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TUCSON AZ
759 PM MST MON APR 25 2016

.SYNOPSIS...COOLER TEMPERATURES AND GUSTY WINDS WILL REMAIN IN
PLACE TUESDAY AS A STORM SYSTEM SHIFTS EASTWARD THROUGH THE
WESTERN US. A BRIEF BREAK WEDNESDAY WILL BE FOLLOWED UP WITH
ANOTHER STORM SYSTEM THURSDAY AND FRIDAY. GUSTY WINDS...COOL
TEMPERATURES...AND A CHANCE OF PRECIPITATION WILL ACCOMPANY THE
STORM.

&&

.DISCUSSION...AN IMPRESSIVE STORM SYSTEM CONTINUES TO CHURN OVER
UTAH AND COLORADO THIS EVENING. CLOUDINESS ASSOCIATED WITH THE LOW
STRETCHES FROM MONTANA TO ARIZONA. THE AFTERNOON KTUS SOUNDING
INDICATED A WELL MIXED ATMOSPHERE WITH STRONG WINDS CLOSE TO THE
SURFACE. THESE WINDS...ALONG WITH A TIGHT PRESSURE GRADIENT...LED
TO STRONG WINDS IMPACTING THE AREA AND POCKETS OF SIGNIFICANT
BLOWING DUST. THE POTENTIAL FOR A REPEAT PERFORMANCE EXISTS
TOMORROW...HOWEVER...THE BEST CHANCE WILL BE ISOLATED MORE TO THE
EAST CLOSER TO THE NEW MEXICO BORDER. WINDS ALOFT ARE FORECAST TO
BE ABOUT THE SAME STRENGTH AS TODAY...BUT HIGH PRESSURE WILL BE
NOSING EASTWARD TOWARD THE AREA PERHAPS LIMITING FULL MIXING OF
THE ATMOSPHERE. TRAVELERS ALONG 191 AND I-10 IN GRAHAM AND COCHISE
COUNTIES COULD EXPERIENCE POCKETS OF BLOWING DUST DURING THE
AFTERNOON.

WEDNESDAY LOOKS LIKE A QUIETER AND WARMER DAY THEN ANOTHER
SIGNIFICANT SYSTEM DROPS INTO ARIZONA THURSDAY AND FRIDAY. MUCH
COOLER TEMPERATURES...GUSTY WINDS...CLOUD COVER...AND THE THREAT
OF SHOWER/THUNDERSTORMS WILL ACCOMPANY THE STORM. MODEL
PROJECTIONS BRING THIS SYSTEM FURTHER SOUTH THAN THE CURRENT
SYSTEM...MEANING PRECIPITATION CHANCES LOOK BETTER. WINDS WILL
AGAIN BE A CONCERN THURSDAY AND FRIDAY.

IMPROVING WEATHER IS EXPECTED FOR THE WEEKEND WITH TEMPERATURES
APPROACHING SEASONABLE LEVELS AND WINDS AT NORMAL VALUES.

&&

.AVIATION...VALID THRU 27/06Z. WINDS AND GUSTS GRADUALLY
SUBSIDING THROUGH 26/08Z. EXPECT TURBULENCE AROUND AND DOWNWIND OF
MOUNTAINS INTO TONIGHT. GUSTY SURFACE WINDS WILL DEVELOP AGAIN
TOMORROW AFTERNOON...STRONGEST EAST OF KTUS WITH A FEW GUSTS OF 25
TO 30 KTS. AVIATION DISCUSSION NOT UPDATED FOR TAF AMENDMENTS.


&&

.FIRE WEATHER...EXPECT LESS WIND TOMORROW...ALTHOUGH SOME
AFTERNOON NORTHWESTERLY GUSTS TO AROUND 30 MPH WILL BE
POSSIBLE...MAINLY EAST OF TUCSON. CRITICAL FIRE WEATHER CONDITIONS
MAY BRIEFLY BE MET FOR A FEW HOURS DURING THE AFTERNOON HOURS NEAR
THE ARIZONA/NEW MEXICO BORDER.

WE WILL BE IN BETWEEN WEATHER SYSTEMS ON WEDNESDAY WHICH WILL
RESULT IN BRIEFLY WARMER TEMPERATURES AND A FEW SOUTHWESTERLY
BREEZES. ANOTHER STORM SYSTEM WILL MOVE INTO THE REGION ON
THURSDAY RESULTING IN A RENEWED RISK FOR CRITICAL FIRE WEATHER
CONDITIONS...MAINLY FOR SOUTHERN PORTIONS OF FIRE WEATHER ZONE 152
AND POSSIBLY THE FAR SOUTHEASTERN PORTIONS OF 151.

BREEZY CONDITIONS WILL BE CONTINUE FRIDAY AND THROUGH THE UPCOMING
WEEKEND ALONG WITH A SLIGHT CHANCE FOR MAINLY AFTERNOON SHOWERS AND
THUNDERSTORMS NORTH OF TUCSON.
