AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
954 AM MDT MON JUL 14 2014

.SYNOPSIS...MONSOON MOISTURE WILL REMAIN OVER THE AREA TODAY AND
TONIGHT. A WEAK STORM PUSHING THROUGH THE NORTHERN ROCKIES TONIGHT
WILL PUSH A WEAK COLD FRONT INTO UTAH TUESDAY THAT WILL LEAD TO A
DAY OF ACTIVE CONVECTION OVER CENTRAL AND SOUTHERN UTAH TUESDAY
AFTERNOON AND EVENING.

&&

.DISCUSSION...SOMEWHAT EAST/WEST ORIENTED RIDGE AXIS OVER UTAH AT
ABOUT 500MB THIS MORNING. SHOWERS AND THUNDERSTORMS JUST EXITING
EXTREME SOUTHERN UTAH PAST FEW HOURS AND HRRR INDICATES SOUTHERN
UTAH BORDER AREA SHOULD BE RELATIVELY QUIET THROUGH AT LEAST MID
AFTERNOON.

SLC SOUNDING SHOWS SOME EASTERLY FLOW AT 700 MB AND BELOW AND
GUSTY EASTERLY WINDS HAVE BEEN OBSERVED NEAR WASATCH CANYON MOUTHS
AND OVER GREAT SALT LAKE THIS MORNING. EXPECT THESE WINDS TO
DIMINISH AS MORE TYPICAL MOUNTAIN/VALLEY/LAKE THERMAL CIRCULATIONS
DEVELOP DURING THE DAY.

SOME DIURNAL CONVECTION LIKELY TO DEVELOP OVER SOUTH/CENTRAL
MOUNTAINS THIS AFTERNOON.

OVERNIGHT MODELS AND NEW 12Z NAM SUGGEST TAIL END OF SHORT WAVE
TROUGH MOVING THROUGH NORTHERN ROCKIES TODAY WILL LEAD TO SOME
ORGANIZATION OF CONVECTION OVER NORTHWEST CORNER OF UTAH THIS
EVENING. THIS CONVECTION AND THE ASSOCIATED CLOUDS DRIFT SOUTH
OVER THE URBAN WASATCH FRONT OVERNIGHT. NO CHANGES IN CURRENT
FORECASTS BUT WILL CONSIDER INCREASING POPS AND PERHAPS OVERNIGHT
MIN TEMPS IF OTHER 12Z MODELS COME IN WITH SIMILAR IDEA.

SUBTLE BOUNDARY ASSOCIATED WITH THE PASSING SHORTWAVE WILL SETTLE
OVER CENTRAL UTAH BY MID DAY TUESDAY AND MAY SERVE TO FOCUS
CONVECTION OVER CENTRAL AND SOUTHERN UTAH TUESDAY AFTERNOON.
TUESDAY COULD BE AN ACTIVE THUNDERSTORM DAY OVER THE SOUTH.

BEST CHANCE TO HIT 100F AT SLC THIS WEEK IS TODAY...AS REST OF
WEEK WILL BE SOMEWHAT COOLER ALOFT IN NORTHWEST FLOW. WARM START
THIS MORNING WILL HELP.

NO CHANGES TO CURRENT FORECAST AT THIS TIME.

&&

.AVIATION...THE SLC TERMINAL WILL SEE VFR CONDITIONS THROUGHOUT THE
DAY WITH SOME SCATTERED CLOUDS DEVELOPING. SOUTHERLY WINDS ARE
EXPECTED TO SHIFT TO THE NORTHWEST BETWEEN 18Z AND 20Z. A 40%
CHANCE OF WIND SHIFT BY 17Z.
