AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
930 AM MDT MON JUL 25 2005

.SYNOPSIS...A DRYING TREND IS UNDERWAY ACROSS THE STATE TODAY...WITH
COOLER AIR MOVING IN TONIGHT AND LASTING THROUGH TUESDAY. HIGH
PRESSURE WILL BUILD ACROSS THE REGION FOR THE LATTER PART OF THE
WEEK.

&&

.DISCUSSION...HEAVIEST SHOWERS/THUNDERSTORMS OVER SOUTHEASTERN UTAH
THIS MORNING DEPARTING. GOT A 0.85 INCH REPORT FROM HITE MARINA ON
LAKE POWELL THIS MORNING...AND MANY SIMILAR REPORTS FARTHER
EAST...PROMPTING FLASH FLOOD WATCH FROM GJT. WILL KEEP CLOSE EYE ON
INCOMING REPORTS THIS MORNING...BUT MOST OF THE ACTIVITY IS/WILL BE
OCCURRING FAR ENOUGH EAST TO LEAVE OUT SLC ZONES. RAINFALL REPORTS
WEST OF LAKE POWELL ARE IN THE 0.10 TO 0.25 RANGE.

DISTINCT LEADING EDGE OF DRY AIR ALOFT EXTENDS FROM UTAHS DIXIE
NORTHEASTWARD INTO SOUTHWEST WYOMING. LOWER LEVELS NOT QUITE AS
CLEAR CUT. BANDS OF MOISTURE...EACH ONE A BIT WEAKER...MOVING ACROSS
UTAH AT TIME. ATMOSPHERE BECOMING DRIER WITH EACH BAND THE FINAL
BAND...AND SURFACE COLD FRONT CURRENTLY THROUGH KENV...28F
DEWPOINT...BUT NOT YET THROUGH KELY...53F DEWPOINT. FRONT WILL
CONTINUE EASTWARD AND SCOUR OUT REMAINING MOISTURE. DO EXPECT
AFTERNOON CONVECTION TO BE MOST PREVALENT ACROSS SOUTHEAST UTAH
TODAY WITH COLD FRONT PASSAGE HELPING TO MAXIMIZE LIFT DURING MAX
HEATING. AGAIN...WILL HOLD OFF ON FLASH FLOOD STATEMENTS FOR NOW
WITH MOST OF THE ACTIVITY TOO FAR EAST.

REALLY NICE WEATHER ON TAP FOR TUESDAY/WEDNESDAY...HIGHS IN THE
80S/LOW 90S ACROSS NORTHERN UTAH...INCREASING TO NEAR 100 IN DIXIE.
700MB TEMPS GENERALLY IN THE SINGLE DIGITS FOR NORTHERN
UTAH...ENJOY ISOLATED CONVECTION STILL POSSIBLE SOUTHEAST UTAH WITH
LINGERING MOISTURE.

HIGH REBUILDS FROM THE WEST STARTING THURSDAY...WITH ANOTHER GRADUAL
INCREASE IN MOISTURE INTO THE WEEKEND. NOT NEARLY AS WARM AS LAST
WEEK...BUT GUIDANCE IN AGREEMENT WITH THE WARMUP.

&&

.FIRE WEATHER...DRIER/COOLER AIR WILL SPREAD OVER NORTHERN UTAH
TODAY WITH LITTLE IF ANY CONVECTION. SCATTERED AFTERNOON
THUNDERSTORMS ARE EXPECTED OVER THE EASTERN HALF OF THE STATE...BUT
WITH ABUNDANT MOISTURE IN PLACE...EXPECT PRIMARILY WET
THUNDERSTORMS CAPABLE OF PRODUCING WETTING RAINS.

&&

.AVIATION...TIMING OF ONSET OF NORTHWESTERLIES AT SLC A BIT TRICKY
AS WEAK FRONTAL BOUNDARY LURKING OUT OVER DUGWAY. FRONTS TEND TO
HANG UP ALONG THE OQUIRRHS...SO THE WIND SHIFT THIS MORNING MAY BE A
BIT DELAYED. STILL EXPECT IT NEAR IN THE 17-18Z TIMEFRAME. A BIT
GUSTY OUT OF THE NORTHWEST THIS AFTERNOON WITH LAKE BREEZE
ENHANCEMENT.

&&

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