AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
853 AM MDT TUE AUG 4 2015

.SYNOPSIS...HIGH PRESSURE WILL BRIEFLY BUILD ACROSS THE
REGION TODAY...BEFORE A WEAK COLD FRONT CROSSES NORTHERN UTAH
WEDNESDAY. MONSOONAL MOISTURE WILL RETURN TO THE REGION LATE IN
THE WEEK.

&&

.DISCUSSION...SHORT WAVE RIDGING IS ADVANCING OVER THE NORTHERN CWA
THIS MORNING WHILE A WEAK UPPER LEVEL WAVE IS MOVING INTO SWRN
UT. THE SHORT WAVE RIDGE OVER THE NORTH WILL KEEP THE ABUNDANT
MOISTURE IN PLACE SUPPRESSED FOR MOST OF THE DAY. MODELS DO SHIFT
THIS WAVE EAST BY 00Z AND FINALLY DEVELOP ISOLATED CONVECTION
OVER THE NERN MTNS AND THE FAR NORTHWEST. THE SRN WAVE LOOKS LIKE
IT WILL SHIFT EAST TOO FAST TO ASSIST THE AFTN HEATING WITH ANY
CONVECTION AND DO NOT EXPECT MUCH MORE THAN MINOR BUILDUPS OVER
THE SRN MTNS IN THE DRIER AIRMASS OVER THE SOUTH.

A BETTER DEFINED SHORT WAVE TROF IS APPROACHING THE CA COAST AT
THIS TIME AND IS FORECAST TO LIFT INTO THE WRN GREAT BASIN BY WED
MORNING AND CROSS THE NRN CWA WED AFTN. THIS SHOULD BRING A BETTER
CHANCE OF CONVECTION TO AREAS MAINLY N OF I-80 WED AFTN INTO THE
EVE. RIDGING BRIEFLY RETURNS TO THE AREA THU.

NO UPDATES PLANNED FOR NOW.

&&

.AVIATION...SOUTHERLY WINDS AT THE KSLC TERMINAL WILL SHIFT TO
NORTHWESTERLY BETWEEN 18Z AND 20Z.

&&

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