AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
945 AM MDT TUE JUL 17 2007

.SYNOPSIS...A MOIST SOUTHERLY FLOW WILL BE OVER THE AREA TODAY. A
DRIER SOUTHWEST FLOW WILL BEGIN TO PUSH INTO THE AREA WEDNESDAY.

&&

.DISCUSSION...A VERY MOIST AIRMASS OVER THE AREA THIS MORNING WITH
SLC 12Z SOUNDING SHOWING A PW OF 1.20 INCHES. WELL DEFINED SHORT
WAVE MOVING THROUGH N. UT THIS MORNING WITH A CIRCULATION CENTER
OVER ABOUT UTAH COUNTY AT 1530Z. A FEW LIGHTNING STRIKES EMBEDDED IN
THIS GENERALLY STRATIFORM CLOUD COVER. SOME MESONET SITES HAVE HAD
.01 PRECIP AND A TRACE OCCURRED AT THE SLC AIRPORT. THESE SHOWERS
WILL CONTINUE NORTHWARD AND BE OUT OF THE FORECAST AREA LATER THIS
AFTERNOON. CLOUDS AND COOLER AIR ALOFT OVER THE NORTH SUGGEST LOWER
MAX TEMPS AND HAVE UPDATED FORECAST GRIDS AND ZONE FORECASTS TO
REFLECT LOWER MAX TEMPS TODAY.

OF GREATER CONCERN IS THE NEXT SHORT WAVE THAT SHOWS UP VERY CLEARLY
IN WATER VAPOR IMAGERY IN EAST CENTRAL NV THIS MORNING WITH A FEW
ACTIVE THUNDERSTORMS. THIS TROUGH AXIS WELL DEFINED AS A 300 MB
VORTICITY TROUGH IN 12Z NAM ANALYSIS AND IT MOVES THROUGH N. UT
THIS AFTERNOON AND EVENING. A MINUS 8 DEGREE COOL POCKET AT 500 MB
ALSO ASSOCIATED WITH THIS TROUGH AND 400 MB TO 850 MB VERTICAL SHEAR
SUGGESTS 40 TO 50 KNOTS OF SHEAR. THIS MORNINGS SLC SOUNDING SHOWS
ABOUT 1150 JOULES OF CAPE THIS AFTERNOON WITH A 90/52 PARCEL...WHICH
SHOULD BE NO PROBLEM TO ATTAIN AND GIVEN COOLING ALOFT...ACTUAL CAPE
LIKELY TO BE HIGHER ALTHOUGH THIS IS IMPOSSIBLE TO VERIFY IN 12Z NAM
GIVEN ITS PROBLEMS WITH THE GSL.  SOME STRONG ORGANIZED
THUNDERSTORMS APPEAR LIKELY THIS AFTERNOON IN NW UTH. SO HAVE ADDED
POTENTIAL FOR SMALL HAIL AND GUSTY WINDS TO FORECAST GRIDS AND ZONE
FORECAST FOR THE THIS AFTERNOON AND EARLY EVENING.

DRYING TREND BEGINS FROM THE WEST TOMORROW...WITH IMPACT ON FIRE
WX...SEE BELOW.

&&

.AVIATION...LOCAL LIGHT NORTHWEST WINDS AT THE KSLC TERMINAL EARLY
THIS MORNING SHOULD SWITCH BACK TO SOUTHERLY BY 13Z AS AN UPPER
LEVEL SYSTEM LIFTS INTO NRN UT ACCOMPANIED BY AREAS OF LIGHT RAIN.
THIS SYSTEM CLEARS THE AREA THIS AFTERNOON AND WINDS SHOULD SWITCH
TO NORTHWEST AGAIN AFTER 20Z.

&&

.FIRE WEATHER...RIDGE AXIS REMAINS TO THE EAST THROUGH MID WEEK.
MOISTURE REMAINS OVER UTAH THROUGH TODAY BEFORE A BRIEF DRYING TREND
OCCURS OVER WESTERN UT ON WED AND THU. EXPECT WET STORMS TODAY BUT
STILL WITH LOCAL GUSTY WINDS. THE DRYING IS NOT FORECAST TO REACH
VERY FAR EAST AND STORMS ARE STILL POSSIBLE WED OVER WRN UT...BUT
THEY WILL BE A LITTLE DRIER.

HUMIDITIES ARE FORECAST TO FALL TO NEAR OR BELOW CRITICAL LEVELS AND
WINDS WILL BE MARGINALLY STRONG ENOUGH FOR LOCAL EXTREME FIRE WEATHER
CONDITIONS BOTH WED AND THU IN THE WRN VALLEYS.

&&
