What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Salt Lake City, UT wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 16, 3:11 PM MDT, 59 minutes earlier.

Area forecast discussion, Jul 16, 3:11 PM MDT, 59 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
311 PM MDT MON JUL 16 2012

.SYNOPSIS...A DRYING TREND WILL BEGIN TODAY AND CONTINUE THROUGH
MID WEEK WITH DRIER CONDITIONS REMAINING IN PLACE INTO THURSDAY.
MOISTURE IS EXPECTED TO RETURN TO THE AREA LATE IN THE WEEK.

&&

.DISCUSSION...SHOWERS AND THUNDERSTORMS HAVE QUICKLY DEVELOPED THIS
AFTERNOON ACROSS PORTIONS OF SOUTHERN UTAH. THESE THUNDERSTORMS
ARE LIKELY ASSOCIATED WITH SEVERAL SUBTLE SHORTWAVES MOVING ACROSS
UTAH AND NEVADA.

SUNNY SKIES THIS MORNING ALLOWED DECENT INSTABILITY TO DEVELOP
ACROSS MUCH OF THE CWA. BLENDED TPW IMAGERY INDICATES PW VALUES
REMAIN BETWEEN 0.80 AND 1 INCH. SREF ENSEMBLE FORECASTS INDICATE
THERE IS SUFFICIENT SHEAR ACROSS THE AREA TO SUPPORT
CONVECTION...WITH A FEW CELLS CAPABLE OF ACHIEVING SOME
ORGANIZATION.

WITH SUFFICIENT MOISTURE...AT LEAST MARGINAL INSTABILITY...AND
SHEAR...EXPECT CONVECTION TO CONTINUE TO DEVELOP. ISOLATED FLASH
FLOODING REMAINS A THREAT. ALSO CANT RULE OUT A FEW CELLS BEING
CAPABLE OF PRODUCING SMALL HAIL.

DRIER AIR IS EXPECTED TO MOVE INTO THE AREA TONIGHT IN TUESDAY
BRINGING AN END TO THIS MONSOONAL SURGE. THE NEXT CHANCE FOR
ANOTHER MOISTURE SURGE APPEARS TO BE FRIDAY INTO SATURDAY.

&&

.AVIATION...SHOWERS AND THUNDERSTORMS WILL IMPACT THE SLC TERMINAL
THROUGH 22Z. WIND GUSTS IN EXCESS OF 35 MPH WITH BRIEF HEAVY RAIN
WILL OCCUR WITH THESE STORMS. THERE IS A 30 PERCENT CHANCE OF IFR
CONDITIONS DUE TO REDUCED VISIBILITY IN HEAVY RAIN. A BREAK IN
ACTIVITY IS LIKELY BETWEEN 22Z AND 23Z BUT ISOLATED THUNDERSTORMS
COULD STILL IMPACT THE TERMINAL THROUGH 01Z.

&&

.FIRE WEATHER....FIRE WEATHER...SHOWERS AND THUNDERSTORMS HAVE DEVELOPED
 ACROSS THE MAJORITY OF THE STATE...AND ARE EXPECTED TO CONTINUE
THROUGH SUNSET. WITH THESE STORMS...EXPECT GUSTY...ERRATIC
WINDS...HEAVY RAIN...AND LIGHTNING.

SOUTHWESTERLY FLOW WILL DEVELOP TOMORROW...BRINGING DRIER AIR
INTO THE STATE. WHILE ISOLATED CONVECTION MAY DEVELOP ALONG THE
HIGHER TERRAIN TOMORROW AFTERNOON...AREAL COVERAGE AND INTENSITY
WILL BE MUCH LESS THAN WHAT HAS BEEN SEEN TODAY. A
WARMING...DRYING TREND WILL CONTINUE INTO THURSDAY...WITH
ENHANCED SOUTHWEST FLOW OVER THE STATE. THERE IS THE POTENTIAL
FOR HAZARDOUS FIRE WEATHER CONDITIONS TO DEVELOP WEDNESDAY
AFTERNOON.

MONSOONAL MOISTURE IS EXPECTED TO RETURN TO THE STATE THIS
WEEKEND...ALTHOUGH THERE IS DISAGREEMENT AMONG WEATHER MODELS AS
TO HOW QUICKLY THE MOISTURE WILL RETURN.
