AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
941 PM MDT TUE AUG 25 2015

.SYNOPSIS...MOISTURE WILL SPREAD NORTHWARD ACROSS THE AREA AS AN
UPPER LEVEL DISTURBANCE MOVES ACROSS THE REGION TONIGHT THROUGH
WEDNESDAY. HIGH PRESSURE WILL RETURN FOR THE LATTER HALF OF THE
WEEK INTO THE UPCOMING WEEKEND.

&&

.DISCUSSION...SOUTHERLY FLOW OVER THE AREA THIS EVENING CONTINUES TO
SPREAD MOISTURE INTO UTAH FROM ARIZONA. A SHORTWAVE DISTURBANCE
LIFTING NORTH INTO SOUTHWEST UTAH IS FINALLY STARTING TO BRING
GREATER AREAL COVERAGE OF SHOWERS TO SOUTHERN UTAH...AND THIS
COVERAGE SHOULD INCREASE THROUGH THE NIGHT AND EXPAND NORTHWARD. AT
THE MOMENT HOWEVER...NORTHERN UTAH IS FAIRLY QUIET WITH JUST SOME
WEAK ISOLATED SHOWERS...ALTHOUGH THESE HAVE BEEN ASSOCIATED WITH
SOME MICROBURST ACTIVITY.

ALTHOUGH PRECIPITATION WILL BECOME MORE WIDESPREAD OVERNIGHT...MOST
OF THE SHOWERS ARE NOT EXPECTED TO BE PARTICULARLY HEAVY DUE TO THE
NIGHTTIME TIMING AND INSTABILITY BEING RATHER WEAK. HOWEVER...THE
WAVE WILL STILL BE TRANSITING NORTHERN UTAH DURING THE DAY
TOMORROW...AND AMPLE MOISTURE WILL REMAIN IN PLACE AREAWIDE.
ALTHOUGH CLOUD COVER MAY WORK AGAINST INSTABILITY...TOMORROW IS
STILL EXPECTED TO BECOME MORE ACTIVE IN TERMS OF COVERAGE AND
INTENSITY OF SHOWERS.

UPDATED THE FORECAST MAINLY TO INCREASE SKY COVER FOR THE REST OF
THE NIGHT AND TO LOWER EVENING POPS FOR THE NORTH.

&&

.AVIATION...SOUTHERLY WINDS WILL BECOME ESTABLISHED OVER THE SLC
TERMINAL BY 04-05Z AND MAY BECOME GUSTY AFTER SUNRISE. SHOWERS WILL
GRADUALLY FILL IN OVER NORTHERN UTAH OVERNIGHT...AND MAY START TO
IMPACT THE TERMINAL MAINLY AFTER 08Z. MORE WIDESPREAD PRECIPITATION
IS EXPECTED BY LATE WEDNESDAY MORNING. GUSTY AND ERRATIC WINDS WILL
BE POSSIBLE NEAR ANY SHOWERS.

&&

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