AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1053 AM MDT SAT AUG 5 2006

.SYNOPSIS...HIGH PRESSURE EAST OF THE AREA WILL KEEP A MOIST
AIRMASS MOVING MAINLY OVER SOUTHERN AND EASTERN UTAH. AN APPROACHING
TROUGH OF LOW PRESSURE WILL INCREASE INSTABILITY OVER THE WEEKEND
AND COULD BRING A SLIGHT COOLING TREND TO THE AREA FOR MIDWEEK.

&&

.DISCUSSION...LATEST SATELLITE IMAGERY INDICATES SHORTWAVE ELONGATING
ALONG THE NORTHWEST BORDER AND MOISTURE MOVING EAST. ENOUGH MOISTURE
REMAINS IN PLACE TO KEEP CONVECTION FIRING OVER SOUTHEASTERN PORTION
OF THE AREA TODAY AS 700MB MIXING RATIOS EXCEED 6-8 G/KG. ALSO...A
PRESENCE OF A JET STREAK MOVING OVER CENTRAL NEVADA SHOULD CREATE
SOME ENERGY FOR SHOWERS TO DEVELOP OVER THE SOUTHEASTERN AND
EASTERN PORTION OF THE AREA. OTHERWISE...DRIER SOUTHWEST FLOW SHOULD
KEEP NORTHERN UTAH DRY THROUGH THE WEEKEND. THE ONLY EXCEPTION TO
THIS IDEA MAY BE INCREASING STABILITY ASSOCIATED WITH AN
APPROACHING THE EASTERN PACIFIC.

CONVECTION SHOULD BE A BIT STRONGER ON MONDAY AS A MODERATELY MOIST
AIRMASS REMAINS OVER THE AREA WITH 700 MB 4-8 G/KG MIXING RATIOS...
AND JET DYNAMICS INCREASE OVER THE AREA. 200 MB WINDS INCREASE TO
NEAR 90 KNOTS BY TUESDAY MORNING...AND COLD FRONT NOSES INTO
NORTHERN UTAH TUESDAY MORNING. 700 MB TEMPERATURES COOL TO 8
DEGREES CELSIUS TUESDAY MORNING. COOLING TREND SHOULD BE BRIEF AS
WARMING TREND SHOULD DEVELOP FOR LATE WEEK.

RIDGE STRENGTHENS FOR LATE WEEK KEEPING THE AREA IN A SIMILAR
PATTERN TO WHAT WE HAVE SEEN THE LAST COUPLE DAYS...A WARM AIRMASS
WITH MOISTURE PRIMARILY OVER SOUTHERN UTAH.

&&

.AVIATION...LAKE BREEZE MAY BE LATER THAN WHAT THE CURRENT FORECAST
STATES. SOUTHWEST WINDS ARE A BIT STRONGER THIS MORNING THAN
EXPECTED. NO THUNDERSTORMS ARE EXPECTED THIS AFTERNOON AT KSLC BUT
OUTFLOW ARE STILL POSSIBLE FROM A DISTURBANCE MOVING OVER THE
NORTHWEST CORNER OF THE STATE.

&&

.FIRE WEATHER...DRIER AIR HAS SPREAD INTO WESTERN UTAH TODAY WHILE
MOISTURE REMAINS ACROSS THE SOUTHEASTERN PORTIONS. THIS WILL RESULT
IN THE BEST CHANCE OF THUNDERSTORMS AND WETTING RAINS OVER THE
SOUTHEAST AND THE MOUNTAINS OF CENTRAL AND SOUTH CENTRAL UTAH TODAY.
A WEAK DISTURBANCE MAY ALSO KEEP A FEW THUNDERSTORMS OVER EXTREME
NORTHWEST UTAH AS WELL. THIS PATTERN SHOULD CONTINUE INTO TOMORROW
BEFORE MOISTURE INCREASES AGAIN FOR THE EARLY PART OF NEXT WEEK.
