AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
956 PM MDT FRI AUG 22 2014

.SYNOPSIS...A COLD TROUGH WILL IMPACT NORTHERN AND CENTRAL UTAH
TONIGHT AND SATURDAY. ANOTHER TROUGH WILL IMPACT THE AREA EARLY
NEXT WEEK BEFORE HIGH PRESSURE RETURNS FOR THE LATTER PART OF THE
WEEK.

&&

.DISCUSSION...A COOL UPPER TROF IS CENTERED OVER WEST CENTRAL ID
THIS EVE. THE ASSOCIATED COLD FRONT EXTENDS FROM ABOUT PRICE TO
MILFORD AND CONTINUES DRIVING SEWD. A BROAD SWATH OF CONVECTIVE
PRECIP ACCOMPANIES THE COLD FRONT AND HAS CLEARED THE NORTHERN AND
CENTRAL WASATCH FRONT BUT WILL PERSIST IN UT CO A LITTLE WHILE
LONGER. ADDITIONAL SHOWERS OVER NWRN UT ASSOCIATED WITH THE
ADVANCING COLD POOL ALOFT SHOULD CONTINUE TO PROPAGATE EAST AND
FILL BACK IN ACROSS THE NORTHERN AND CENTRAL WASATCH FRONT LATER
TONIGHT.

EXPECT THE SHOWERS AT THE SOUTHERN END OF THE COLD FRONT TO WEAKEN
OVER THE NEXT SEVERAL HOURS AS IT MOVES FARTHER AWAY FROM THE
UPPER SUPPORT WHILE THE PORTION CROSSING CENTRAL AND NERN UT
SHOULD HOLD TOGETHER.

THE UPPER TROF AXIS CROSSES NRN UT AROUND MIDDAY AND EXPECT
PRECIP TO SHUT DOWN RAPIDLY ALONG AND RIGHT BEHIND THIS AXIS WITH
SKIES CLEARING OUT IN THE AFTN ACROSS THE N AND W.

A MOSTLY CLEAR NIGHT SHOULD ALLOW TEMPS TO DIP TO CHILLY LEVELS
SUN MORNING ALTHO THEY WILL REMAIN WELL ABOVE FREEZING IN THE
POPULATED VALLEYS.

SOME CONVECTION IS POSSIBLE ACROSS CENTRAL UT SUN AS THE REMAINS
OF THE COLD FRONT START TO LIFT BACK NORTH AS A WEAK WARM FRONT
AHEAD OF THE NEXT SHORT WAVE THAT DEEPENS THE UPPER TROF AGAIN TO
OUR WEST.

UPDATED EARLIER TO MAKE SOME SHORT TERM ADJUSTMENTS TO POPS SKY
AND WIND. NO ADDITIONAL UPDATES PLANNED.

&&

.AVIATION...A BREAK IN THE SHOWERS AT THE KSLC TERMINAL WILL LAST
THROUGH ABOUT 06Z TONIGHT WITH OCCASIONAL PASSING SHOWERS AFTER
THAT. WINDS HAVE RETURNED TO SOUTHEASTERLY AND SHOULD REMAIN THAT
WAY INTO THE MORNING. HOWEVER GUSTY ERRATIC WINDS ARE POSSIBLE
WITH SHOWERS. VFR CONDITIONS WILL PREVAIL BUT BRIEF MVFR
CONDITIONS ARE POSSIBLE IF A SHOWER PASSES DIRECTLY OVERHEAD.

&&

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