AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
957 AM MDT TUE JUL 14 2015

.SYNOPSIS...THE GREAT BASIN REMAINS BETWEEN HIGH PRESSURE ALOFT
OVER THE SOUTHERN PLAINS AND AN UPPER LEVEL TROUGH ALONG THE WEST
COAST. THE WEST COAST TROUGH WILL TURN EAST AND MOVE ACROSS THE
NORTHERN ROCKIES MIDWEEK.

&&

.DISCUSSION...THERE ARE TWO PRIMARY AREAS OF CONVECTIVE POTENTIAL
TODAY. ACROSS THE NORTHWEST... 500-750 J/KG OF CAPE AND BULK SHEAR
APPROACHING 30 KTS COULD LEAD TO SOME ORGANIZED CONVECTION AND
GUSTY WINDS. ALONG AND EAST OF THE MOUNTAINS, HIGH PWATS MAY
CONTRIBUTE TO BRIEFLY HEAVY SHOWERS AND A FEW THUNDERSTORMS... BUT
THESE WILL BE SHORT LIVED. IN BETWEEN THESE REGIONS... THE
EXPECTED EVOLUTION OF THE MORNING SOUNDING WILL LEAD TO MICROBURST
POTENTIAL OVER THE WEST DESERT. OVERALL THIS APPEARS TO BE A
FAIRLY QUIET DAY FOR THE MORE POPULATED AREAS ALONG THE WASATCH
FRONT.

POPS WERE INCREASED ALONG AND EAST OF THE MOUNTAINS BASED ON
ELEVATED PWATS AND SHORT-RANGE MODEL GUIDANCE. OVER THE
NORTHWEST... THE POTENTIAL FOR GUSTY WINDS WAS ADDED AS WE WATCH
THE POTENTIAL FOR STRONG DOWNDRAFTS.

&&

.AVIATION...NORTHWEST WINDS AT THE KSLC TERMINAL ARE EXPECTED TO
REMAIN IN PLACE THROUGH THE AFTERNOON DUE TO CONVECTIVE OUTFLOW
REINFORCEMENT AND PRESSURE GRADIENT FROM THE NORTHWEST.

&&

.FIRE WEATHER...THE DRY CONDITIONS AND SOUTHWEST FLOW MAY SUPPORT
LOCALLY CRITICAL FIRE WEATHER CONDITIONS ACROSS SOUTHWEST UTAH TODAY
AND TOMORROW.

LARGE SCALE PATTERN CONSISTS OF SOUTHWEST FLOW ALOFT
BETWEEN A RIDGE IN THE PLAINS AND A TROUGH OVER THE PACIFIC
NORTHWEST. THIS IS SUPPORTING DRY CONDITIONS ACROSS CENTRAL UTAH.
MEANWHILE MOISTURE IS POOLING ACROSS THE NORTHWEST CORNER OF THE
STATE AHEAD OF THE TROUGH...AND THE EASTERN AND SOUTHERN VALLEYS
COURTESY OF MONSOON RETURN FLOW AROUND THE RIDGE.

AFTERNOON AND EVENING CONVECTION SHOULD BE CONCENTRATED ACROSS FAR
NORTHWEST UTAH...AND SOUTH CENTRAL UTAH INTO THE EASTERN VALLEYS.
CLOUD TO GROUND LIGHTNING...LOCALLY GUSTY/ERRATIC WINDS...AND A
BRIEF RAIN ARE EXPECTED WITH THE STRONGER ACTIVITY.

SIMILAR CONDITIONS ARE FORECAST TOMORROW. WEDNESDAY AND THURSDAY THE
TROUGH CROSSES THE NORTHERN ROCKIES...INTRODUCING DRYING WHICH WILL
LIMIT CONVECTION EVEN MORE. WINDS THOUGH DONT LOOK TOO GUSTY.

FRIDAY INTO THE WEEKEND THE TROUGH STRENGTHENS ONCE AGAIN TO OUR
NORTHWEST. THIS WILL DRAW DEEPER MOISTURE NORTHWARD INTO SOUTHERN
AND CENTRAL UTAH ESPECIALLY INCREASING CONVECTIVE COVERAGE AND THE
POTENTIAL FOR MORE WIDESPREAD WETTING RAIN.

&&

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