AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1030 AM MDT SAT SEP 16 2006

.SYNOPSIS...A COLD PACIFIC STORM SYSTEM WILL EXIT THE STATE TODAY.
HIGH PRESSURE ALOFT WILL RETURN EARLY NEXT WEEK. A WEAKER STORM
SYSTEM WILL THEN MOVE ACROSS THE AREA MID-WEEK.

&&

.DISCUSSION...COLD POOL ALOFT ASSOCIATED WITH THE STRONG EARLY
SEASON SYSTEM WILL MOVE ACROSS NORTHERN UTAH THIS AFTERNOON. THE
STRONG DYNAMICS HAVE MOVED NORTH AND EAST OF THE CWA...BUT
ATMOSPHERE REMAINS WITH COOLING ALOFT ONGOING.

THE STORM DROPPED IMPRESSIVE AMOUNTS OF PRECIP. INITIAL REPORTS ARE
1-2+ INCHES OF RAIN ALONG THE WASATCH FRONT. SNOW LEVELS DROPPED TO
THE VALLEY FLOOR NORTH OF SALT LAKE CITY...SNOW FELL AND AT 4700FT
IN NORTHERN DAVIS AND SOUTHERN WEBER COUNTIES. MOUNTAIN REPORTS
GENERALLY 4 TO 6 INCHES.

H7 TEMP AT -7C OVER SLC...WITH A -8 TO -9 POOL UPSTREAM. EXPECT THE
COLDEST AIR TO BE OVERHEAD BETWEEN 18Z AND 00Z...SO WITH BREAKS OF
SUN...THERE WILL BE A FAIR AMOUNT OF WELL DEVELOPED CU AND SHOWERS.
THE WIND ALIGNMENT WOULD FAVOR ANY LAKE DEVELOPMENT TO MOVE WEST
INTO NORTH SALT LAKE AND DAVIS COUNTY RATHER THAN INTO SALT LAKE
COUNTY. ISOLATED POPS IN THE VALLEYS SHOULD SUFFICE...SO ANY UPDATES
WILL BE TO TWEAK UP POPS SLIGHTLY IF NECESSARY.

THE NEXT ISSUE WILL BE THE POTENTIAL FOR FROST/FREEZE IN MANY OF THE
VALLEYS. THE CACHE/SALT LAKE/UTAH/SEVIER VALLEYS AND WELL AS MANY OF
THE DESERTS OF WESTERN UTAH WILL LIKELY SEE A KILLING FROST OR
FREEZE TONIGHT. PLANNING TO UPGRADE THE CURRENT FREEZE WATCH LATER
THIS MORNING TO A WARNING AND ADD THE NORTHWEST DESERTS. THE ONLY
FLY IN THE OINTMENT WILL BE THE AMOUNT OF CLOUD COVER EARLY
TONIGHT...BOTH FROM REMAINING CU FROM TODAY...AND MID LEVEL CLOUDS
FROM WRAP AROUND MOISTURE AS THE MAIN LOW PULLS AWAY.

FROM THERE...THE WEATHER IMPROVES OVER THE NEXT 2 DAYS AS HIGH
PRESSURE ALOFT MOVES IN ON SUNDAY. SUNDAY NIGHT MAY BE ANOTHER
CHILLY NIGHT UNDER CALM WINDS AND MOSTLY CLEAR SKIES. THE HIGH
CRESTS OVER THE REGION MONDAY NIGHT...WITH FLOW BACKING TO SOUTHWEST
BY TUESDAY. EXPECT A BREEZY DAY ON TUESDAY AHEAD OF ANOTHER COOL
PACIFIC SYSTEM. MODEL DIFFERENCES EXIST ON THE STRENGTH OF THE
SYSTEM...BUT ANY SOLUTION THUS FAR IS WEAKER THAN THE STORM THAT
JUST MOVED THROUGH THIS MORNING.

&&

.AVIATION...PERIODS OF CEILINGS DOWN TO 5500FT IN AND NEAR SHOWERS
POSSIBLE TODAY THROUGH 20Z.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...

UT...FREEZE WATCH FOR TONIGHT FOR UTZ001>004-011-012-014>016.

WY...NONE.
