AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
441 AM MDT THU SEP 26 2013

.SYNOPSIS....A COLD PACIFIC STORM SYSTEM WILL REMAIN OVER UTAH
THROUGH THE BALANCE OF THE WORK WEEK. A MILD AND DRIER WESTERLY
FLOW ALOFT WILL FOLLOW FOR THE WEEKEND.

&&

.DISCUSSION...A LONGWAVE TROUGH ENCOMPASSES THE WESTERN CONUS
EARLY THIS MORNING...ANCHORED AROUND AN UPPER LOW SITUATED ACROSS
SOUTHWEST ID. THE ASSOCIATED SURFACE FRONT EXTENDS FROM ROUGHLY
GREEN RIVER TO KANAB...WITH THE TRAILING MID LEVEL BAROCLINIC ZONE
EXTENDING ACROSS NORTHERN AND CENTRAL UT. A 250MB JET REMAINS
ACROSS NORTHERN UT...AND CONTINUES TO ACT ON THIS BAROCLINIC ZONE
TO PRODUCE SHOWERS EARLY THIS MORNING.

THESE FEATURES WILL SHOW LITTLE EASTWARD MOVEMENT UNTIL AN
EMBEDDED SHORTWAVE TROUGH...CURRENTLY DIGGING THROUGH CENTRAL
CA...FINALLY ROUNDS THE BASE OF THE LONGWAVE LATE TODAY.
ANTICIPATE SHOWERS WILL CONTINUE WITHIN THE BAROCLINIC ZONE
THROUGH THE DAY...AND HAVE INCREASED POPS TO LIKELIES IN MOST
NORTHERN VALLEYS AND CATEGORICAL IN THE NORTHERN
MOUNTAINS...ALTHOUGH QPF WILL GENERALLY BE LIGHT. SNOW LEVELS
SHOULD REMAIN IN THE 6500-7000 FOOT RANGE THROUGH THIS AFTERNOON.

AS THE LONGWAVE TROUGH FINALLY BEGINS TO MOVE EAST TONIGHT A MUCH
MORE FAVORABLE OROGRAPHIC SETUP WILL DEVELOP ACROSS NORTHERN UT
OVERNIGHT INTO FRIDAY MORNING. ADDITIONALLY MUCH COLDER AIR WILL
MOVE ACROSS THE GSL...AND GIVEN THAT LAKE INDUCED SHOWERS AND
THUNDERSTORMS HAVE ALREADY DEVELOPED EARLY THIS
MORNING...ANTICIPATE LAKE ENHANCEMENT TO BE MUCH MORE COMMON
SOUTHEAST OF THE GSL AND OTHER WARM BODIES OF WATER THROUGH FRIDAY
MORNING. ADDITIONALLY...AS 700MB TEMPS FALL TO NEAR -6C SNOW
LEVELS MAY REACH THE UPPER BENCHES BY EARLY FRIDAY MORNING. THIS
PRECIPITATION SHOULD CONTINUE THROUGH THE MORNING HOURS FRIDAY
BEFORE TAPERING OFF DURING THE AFTERNOON AS MID LEVEL TEMPERATURES
WARM.

CONTEMPLATED ISSUING A WINTER WX ADVISORY FOR THE HIGHER TERRAIN
FOR TONIGHT THROUGH FRIDAY...BUT GIVEN THE BRUNT OF THE EVENT IS
NOT EXPECTED UNTIL TONIGHT OPTED TO ALLOW THE DAY SHIFT AN
OPPORTUNITY TO COLLABORATE MESSAGING WITH OTHER AGENCIES.

IN THE WAKE OF THIS WAVE...A STRONG SURFACE HIGH COMBINED WITH
GENERALLY CLEAR SKIES WILL LIKELY ALLOW FOR AREAS OF FROST ACROSS
MANY VALLEY LOCATIONS. A HARD FREEZE IS ALSO POSSIBLE ACROSS
SOUTHWEST UTAH /EXCLUDING UTAHS DIXIE/ SATURDAY MORNING...WITH
SOME POTENTIAL ACROSS WEST CENTRAL UT AND PERHAPS A FEW OUTLYING
AREAS IN THE NORTH.

WESTERLY FLOW ALOFT WILL FOLLOW FOR THE WEEKEND ALLOWING FOR A
QUICK WARMUP AREAWIDE. THIS WESTERLY FLOW WILL STRENGTHEN EARLY
NEXT WEEK...HOWEVER WITH THE JET AXIS REMAINING NORTH OF THE AREA
GENERALLY DRY AND MILD CONDITIONS ARE EXPECTED AREAWIDE.

&&

.AVIATION...CEILINGS AT THE SLC TERMINAL ARE EXPECTED TO BE 7K FT
THROUGH ABOUT MID MORNING BEFORE LOWERING TO NEAR 5K FT. THERE IS A
30 PERCENT CHANCE THAT THIS LOWERING WILL HOLD OFF UNTIL 17-18Z.
MVFR CONDITIONS IN REDUCED VISIBILITY AND OR CIGS IS EXPECTED AFTER
23Z BUT THERE IS A 20 PERCENT CHANCE THAT THIS WILL NOT OCCUR UNTIL
01 OR 02Z. WINDS WILL BE LIGHT SOUTH THIS MORNING BUT SWITCH TO
NORTHWEST AFTER 16Z-17Z.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...NONE.
WY...NONE.
