AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
902 PM MDT FRI JUL 31 2015

.SYNOPSIS...HIGH PRESSURE WILL REMAIN OVER THE FORECAST AREA
THROUGH SATURDAY BEFORE SHIFTING EAST. MOISTURE OVER SOUTHERN UTAH
WILL SPREAD NORTHWARD ON SUNDAY BEFORE DRIER CONDITIONS MOVE IN
BEGINNING MONDAY.

&&

.DISCUSSION...HIGH PRESSURE REMAINS OVER THE AREA THIS EVENING
WITH A NW-SE RIDGE AXIS EXTENDING FROM NWRN NV TO CENTRAL NM.
MOISTURE REMAINS CONFINED TO SOUTHERN UTAH SOUTH OF THIS AXIS
DEEPEST OVER SWRN UT WHERE CONVECTION BECAME SOMEWHAT MORE ACTIVE
TODAY THAN YESTERDAY. LOCAL RAINFALL AMOUNTS OF AROUND 0.1 TO 0.2
INCHES WERE NOTED WHERE STORMS ACTUALLY MANAGED TO HIT AN
AUTOMATED SITE. ONE PARTICULARLY STRONG CELL BROUGHT HEAVY RAIN TO
THE HILDALE AREA IN WASHINGTON COUNTY WITH ONE REPORT OF .91 IN 30
MINS JUST S OF THE UT/AZ BORDER. (THANKS WFO VEF)

THIS HAS PRETTY MUCH ENDED AT THIS TIME ALTHO LOCAL LIGHT SHOWERS
WILL PERSIST FOR A FEW MORE HOURS. THE PATTERN CHANGES LITTLE
DURING THE DAY TOMORROW AND EXPECT SIMILAR CONVECTIVE ACTIVITY.
A FEW OF THE SLOW MOVING STORMS COULD ACTUALLY GENERATE ISOLATED
POCKETS OF HEAVY RAIN.

MODELS CONTINUE TO DEVELOP A SMALL BUT ORGANIZED E-W TROF ALONG
THE UT/AZ BORDER BY 12Z SUN THEN LIFT THIS FEATURE THRU THE CWA
OVER THE NEXT 30-36 HOURS OR SO. THIS COULD KEEP CONVECTION ACTIVE
TOMORROW NIGHT ACROSS THE SOUTH AND SHOULD BRING AT LEAST ISOLATED
ACTIVITY TO MOST OF THE CWA SUNDAY INTO MON. THE SOUTH IS
FORECAST TO DRY IN THE WAKE OF THIS WAVE WITH LIMITED MOISTURE
LINGERING OVER THE NORTH INTO TUE.

UPDATED EARLIER TO ADD MENTION OF SHOWERS WITH THE THUNDERSTORMS
AND TO RAISE POPS ACROSS SWRN UT. UPDATED AGAIN TO LOWER POPS FOR
THE REMAINDER OF THIS EVE AND REMOVE MENTION OF THUNDER. NO
ADDITIONAL UPDATES PLANNED.

&&

.AVIATION...SURFACE WINDS AT THE SLC TERMINAL WILL SWITCH BACK TO
THE SOUTHEAST BY AROUND 04Z AND REMAIN SOUTHERLY INTO SATURDAY
MORNING.

&&

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