AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
949 AM MDT SUN SEP 14 2014

.SYNOPSIS...HIGH PRESSURE ALOFT ACROSS THE GREAT BASIN WILL
STRENGTHEN OVER THE REGION EARLY THIS WEEK. MOISTURE WILL SPREAD
NORTH INTO SOUTHERN UTAH EARLY WEDNESDAY...THEN CONTINUE NORTH
ACROSS THE ENTIRE AREA BY THURSDAY.


&&

.DISCUSSION...THE LOW-AMPLITUDE RIDGE AXIS REMAINS RELATIVELY
STATIONARY AGAIN TODAY...CONTINUING THE 500 MB ZONAL WIND FLOW
REGIME. A MID LEVEL SHORT WAVE TRANSLATING THROUGH THE RIDGE INTO
NORTHERN UTAH THIS AFTERNOON MAY AID IN MIXING THE STABLE
ENVIRONMENT INDICATED BY THE SLC RAOB SOUNDING THIS
MORNING...ENCOURAGING ISOLATED THUNDERSTORMS OVER THE NORTHERN
MOUNTAINS.

A BETTER CHANCE OF STORM ACTIVITY THIS AFTERNOON EXISTS IN
CENTRAL AND SOUTHERN UTAH...WHERE MOISTURE WILL COMBINE WITH AMPLE
HEATING AND DECENT LIFTED INDICES TO PROMOTE ISOLATED AFTERNOON
THUNDERSTORMS ACROSS THE HIGH TERRAIN. CURRENT GOES PWAT VALUES
SUPPORT THIS IDEA...SHOWING VALUES IN EXCESS OF AN INCH OOZING
INTO SOUTHERN UTAH THIS MORNING.


&&

.AVIATION...THE SLC TERMINAL WILL SEE VFR CONDITIONS THROUGHOUT THE
DAY WITH SOME SCATTERED CLOUDS. LIGHT SOUTHEAST WINDS ARE EXPECTED
TO SHIFT TO THE NORTHWEST BETWEEN 18Z AND 20Z.
