NATIONAL WEATHER SERVICE TUCSON AZ
300 AM MST FRI DEC 11 2015

.SYNOPSIS...WINDS WILL INCREASE TODAY AHEAD OF A COLD PACIFIC STORM
SYSTEM. A FEW LIGHT SHOWERS WILL DEVELOP THIS AFTERNOON...THEN
EXPECT A GOOD CHANCE OF VALLEY RAIN AND MOUNTAIN SNOW TONIGHT INTO
SATURDAY MORNING. MUCH COLDER TEMPERATURES ARE EXPECTED THIS
WEEKEND. ANOTHER SYSTEM WILL BRING A FEW VALLEY RAIN AND MOUNTAIN
SNOW SHOWERS MONDAY. EXPECT TEMPERATURES TO REMAIN AROUND 10 TO 15
DEGREES BELOW AVERAGE MUCH OF THE NEW WEEK.

&&

.DISCUSSION...A STRONG TROUGH WILL PUSH ACROSS THE REGION FROM THE
WEST OVER THE NEXT 36 HOURS. A STRENGTHENING SOUTHWESTERLY FLOW
AHEAD OF THE SYSTEM WILL BRING GUSTY WINDS ACROSS SOUTHEAST ARIZONA
TODAY WITH STRONGEST WINDS IN WIND PRONE AND HIGHER ELEVATION AREAS
GENERALLY EAST OF TUCSON. WE HAVE JOINED FLAGSTAFF AND ALBUQUERQUE
OFFICES WITH A WIND ADVISORY FOR OUR FAR EASTERN MOUNTAINS.

WE SHOULD SEE INITIAL LIGHTER UPSLOPE SHOWER ACTIVITY IN THE EARLY
EVENING HOURS AND THEN A SHARPER DELINEATION OF VALLEY RAIN AND
MOUNTAIN SNOW AS THE COLD FRONT PUSHES IN TONIGHT. BEST CHANCE FOR
PRECIP ACROSS THE AREA WILL BE BETWEEN MIDNIGHT AND 8 AM SATURDAY

4000 OR 5000 FEET LATER TONIGHT INTO SATURDAY MORNING.

CLEARING FROM THE WEST BY SATURDAY AFTERNOON WITH COLDER
TEMPERATURES...DOWN 25 DEGREES OR SO COMPARED TO RECENT DAYS. WE MAY
HAVE ENOUGH RESIDUAL BOUNDARY LAYER MOISTURE FOR FROST TO BE A
CONCERN SUNDAY MORNING.

A VERY BRIEF SHORTWAVE RIDGE PHASES THROUGH SUNDAY AFTERNOON WITH NO
REAL TIME FOR TEMPERATURES TO RECOVER IN VALLEYS BEFORE ANOTHER
SYSTEM PUSHES QUICKLY IN FROM THE NORTHWEST MONDAY. THIS SYSTEM
DOESN'T LOOK QUITE AS WET THIS FAR SOUTH...BUT IT LOOKS EVEN COLDER.

MOST OF THE NEW WEEK.
