The episode as NWS SLC wrote it up.
A trough moved through Utah on July 3, helping to initiate scattered showers and thunderstorms across Utah. However, the lower levels of the atmosphere remained quite dry. This was especially true in northwest Utah, where virga caused strong, gusty winds.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1039 AM MDT THU JUL 3 2014
.SYNOPSIS...HIGH PRESSURE ALOFT CENTERED OVER THE INTERIOR WEST
WILL REMAIN THE DOMINANT FEATURE THROUGH THE UPCOMING HOLIDAY
WEEKEND. INCREASING MOISTURE WILL BRING AN INCREASING THREAT OF
AFTERNOON AND EVENING THUNDERSTORMS OVER THE NEXT SEVERAL
DAYS...ESPECIALLY ACROSS SOUTHERN UTAH THIS WEEKEND.
&&
.DISCUSSION...A STRONG MID LEVEL RIDGE POSITIONED IN THE VICINITY
OF THE 4-CORNERS CONTINUES TO WOBBLE IN PLACEMENT WITH CENTER NOW
OVER FAR EASTERN ARIZONA. A DRY SOUTHWESTERLY FLOW HAS BEGUN TO
PUNCH INTO THE FAR SOUTHWEST...WITH A WEAK SHORT WAVE POSITIONED
ALONG ITS LEADING EDGE AND ORIENTED FROM SOUTHEASTERN TO
NORTHWESTERN UTAH. WEAK CONVECTION ASSOCIATED WITH THIS REMAINS
HIGH BASED AND SHALLOW...WITH ONLY VIRGA AT THIS TIME DUE TO DRY
LOW LEVELS IN PLACE.
MODEST MID LEVEL MOISTURE COINCIDENT WITH THE AFOREMENTIONED
WAVE...UP TO .70 INCHES PWAT...WILL CONTINUE TO SPREAD EAST
NORTHEAST ACROSS CENTRAL/NORTHERN/EASTERN UTAH TODAY. SPC SREF
ENSEMBLES AND BUFKIT PROFILES CONTINUE TO INDICATE MODEST
DESTABILIZATION THIS AFTERNOON WITH MUCAPE NOSING TOWARDS 500
J/KG ACROSS THE NORTH. ISOLATED TO SCATTERED GUSTY SHOWERS/STORMS
REMAIN FORECAST FOR THIS AFTERNOON/EVE DUE TO THE ABOVE MENTIONED
PARAMETERS. OF NOTE...THE FAR SOUTHWEST THE ONE AREA WHICH SHOULD
SEE DIMINISHED CONVECTION TODAY. EXPANDED SLIGHT CHANCE POPS AS
FAR SOUTH AS DELTA AND ACROSS THE SWELL/LAKE POWELL REGIONS DUE TO
RECENT TRENDS IN HI- RES OUTPUT AND ANALYSIS...THIS AS THE ONLY
UPDATE THIS MORNING.
CLOUD COVER REMAINS PLENTIFUL WITH THIS SHORT WAVE...AND THOUGH
MANY AREAS HIT THE GROUND RUNNING THIS MORNING AFTER A VERY WARM
NIGHT SAID CLOUDS VERY WELL COULD LIMIT REACHING FULL POTENTIAL
FROM +17 H7 TEMPERATURES. REGARDLESS...TODAY SHOULD BE THE WARMEST
DAY THUS FAR THIS SUMMER.
A NORTHWARD SHIFT OF THE HIGH WILL OCCUR OVER THE NEXT 24 HOURS
AND IS EXPECTED TO NOT ONLY ALLOW A NET DRYING TREND OVER
NORTHERN/CENTRAL UTAH...BUT WILL ALSO STABILIZE THE MID LEVELS
SOME DUE TO A MORE SUBSIDENT ENVIRONMENT. RETURN FLOW AROUND THIS
HIGH WILL BEGIN ANOTHER AND MORE NOTABLE MOISTURE SURGE ACROSS THE
FAR SOUTH AND SOUTHWEST LATE TOMORROW THROUGH THE WEEKEND...BUT
GUIDANCE IS SUGGESTING THE FOCUS OF THIS WILL PUSH NORTHWEST
THROUGH NEVADA AS THE HIGH ELONGATES AND BULGES EAST EARLY NEXT
WEEK.
&&
.AVIATION...WINDS AT THE SLC TERMINAL WILL BE SOUTHERLY AND GUSTY AT
TIMES THROUGH ABOUT 21-23Z THEN WINDS SHOULD SWITCH TO
NORTHWESTERLY. THERE IS A 40 PERCENT CHANCE THAT WINDS WILL NOT
SWITCH AND REMAIN SOUTHERLY INTO TONIGHT. THERE IS A CHANCE THAT
SHOWERS AND ISOLATED THUNDERSTORMS COULD INDIRECTLY IMPACT THE
TERMINAL IN THE AFTERNOON AND EVENING WITH GUSTY ERRATIC OUTFLOW
WINDS.
&&
.FIRE WEATHER...ISOLATED TO WIDELY SCATTERED DRY THUNDERSTORMS WILL
CONTINUE ACROSS MOST OF UTAH EXCEPT THE FAR SOUTHWEST TODAY. CURRENT
RED FLAG WARNING LOOKS ON TRACK. ANY COVERAGE OVER THE NORTHWEST
DESERTS SHOULD REMAIN TOO ISOLATED TO WARRANT EXPANDING THE WARNING
AT THIS TIME. THERE IS A SMALL CHANCE OF WETTING RAIN FROM STORMS
OVER THE SOUTH. SOMEWHAT DRIER AND MORE STABLE AIR WILL PUSH INTO
WESTERN UTAH FRIDAY WITH A REDUCED CHANCE OF THUNDERSTORMS WHILE A
THREAT OF CONVECTION WILL CONTINUE FOR THE SOUTH AND EAST. MOISTURE
WILL INCREASE ACROSS SOUTHERN UTAH INTO THE WEEKEND WITH AN
INCREASING CHANCE OF WET STORMS WHILE THE NORTH REMAINS MOSTLY DRY.
&&
.SLC WATCHES/WARNINGS/ADVISORIES...
UT...RED FLAG WARNING UNTIL 10 PM MDT THIS EVENING FOR UTZ489-491-
