AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
850 PM MDT SAT JUL 18 2009

.SYNOPSIS...STRONG HIGH PRESSURE WILL REMAIN IN PLACE THROUGH THE
WEEKEND. MOISTURE WILL BEGIN TO MOVE INTO THE REGION THROUGH
SUNDAY...THEN REMAIN THROUGH MID WEEK.

&&

.DISCUSSION...WATER VAPOR LOOP SHOWS A RIDGE DOMINATING THE
SOUTHWEST CONUS. A STRONG WAVE EMBEDDED IN THE MEAN WESTERLIES ALONG
THE CANADIAN BORDER IS NEARING THE NORTHERN ROCKIES. MEANWHILE...AN
UPPER LOW IS STALLING NEAR 142W/40N. 400-250MB ACARS WIND
OBSERVATIONS REVEAL LIGHT ANTICYCLONIC FLOW ALOFT. A 75-110KT
ANTICYCLONIC JET WAS LOCATED ACROSS SOUTHWEST CANADA...DIVING SOUTH
ACROSS THE CENTRAL CONUS. 00Z 700MB ANALYSIS SHOWS RIDGING IN PLACE
ACROSS THE SOUTHWEST CONUS. COOL ADVECTION WAS INITIATING LOCALLY
WITH +18C AT KSLC AND +16C UPSTREAM AT KLKN.

00Z KSLC RAOB INDICATES ABOUT 1 TO 3C OF COOLING ABOVE 550MB AND
SLIGHT WARMING IN THE LOWER LEVELS DURING THE PAST 24 HOURS. THE
PRECIPITABLE WATER VALUE HAS RISEN TO THREE QUARTERS OF AN
INCH...THOUGH A CLASSIC INVERTED-V SIGNATURE WAS IN PLACE.

INCREASING MID LEVEL MOISTURE WITHIN THE RIDGE HAS SUPPORTED HIGH
BASED CONVECTION THIS AFTERNOON AND EARLY EVENING ACROSS PRIMARILY
WESTERN AND SOUTHERN UTAH. GIVEN AN INVERTED-V SOUNDING AND SURFACE
DEWPOINT DEPRESSIONS OF 60-75F...WIND GUSTS OF 35-50 MPH ARE
OCCURRING WITH THIS ACTIVITY. CONVECTION WILL DIMINISH OVERNIGHT
WITH LOSS OF DAYTIME HEATING.

HAVE UPDATED POPS TO REFLECT CURRENT TRENDS. ALSO TWEAKED OVERNIGHT
LOWS AND WINDS WITH THE LATEST GUIDANCE. REST UNCHANGED AT THIS
TIME. PREVIOUS DISCUSSION FOLLOWS...

MOISTURE WILL CONTINUE TO INCREASE SUNDAY ACROSS THE ENTIRE CWA.
THIS WILL HELP TO INCREASE THE COVERAGE OF THUNDERSTORMS TO MUCH OF
THE STATE TOMORROW. SEE THE FIRE WEATHER DISCUSSION FOR ADDITIONAL
DETAILS REGARDING THE POTENTIAL FOR DRY LIGHTNING. GUSTY WINDS ARE
POSSIBLE NEAR ANY OF THE STRONGER THUNDERSTORMS TOMORROW WITH A
CLASSIC INVERTED-V TYPE EVENT EXPECTED. ADDED SPECIFIC GUSTY WIND
WORDING TO ALL ZONES TOMORROW TO HIGHLIGHT THE THREAT.

MOISTURE REMAINS IN PLACE FOR MUCH OF THE NEXT WEEK ACROSS THE
REGION...ALTHOUGH THE GFS AND THE EC STILL DIFFER IN THE
EXTENT/DURATION OF THE MOISTURE SURGE. INCREASED POPS IN THE
EXTENDED A BIT TO MATCH THE MORE CONSISTENT EC SOLUTION.

&&

.AVIATION...THE SLC TERMINAL WILL SEE VFR CONDITIONS THROUGH THE
EVENING. NORTHWEST WINDS ARE EXPECTED TO SHIFT TO THE SOUTHEAST
BETWEEN 05Z AND 07Z. THERE IS A 50 PERCENT CHANCE GUSTY OUTFLOW
WINDS ARRIVE FROM TOOELE BETWEEN 03Z AND 04Z...ENHANCING WESTERLY
FLOW AND DELAYING ONSET OF SOUTHEAST DRAINAGE FLOW.

&&

.FIRE WEATHER...A RIDGE OF HIGH PRESSURE WILL REMAIN IN PLACE
ACROSS THE REGION THROUGHOUT MUCH OF THE UPCOMING WEEK. A
WEAK DISTURBANCE MOVING THROUGH THIS HIGH WILL LIKELY SWITCH
RIDGELINE WINDS TO THE WEST SUNDAY AFTERNOON. HIGH BASED MOISTURE
WILL CONTINUE TO INCREASE TONIGHT THROUGH SUNDAY. LIGHTNING
COVERAGE IS EXPECTED TO REMAIN ISOLATED ACROSS THE WESTERN VALLEYS
THIS EVENING...BUT IS EXPECTED TO INCREASE IN COVERAGE SUNDAY WITH
THE PASSAGE OF THIS DISTURBANCE. GIVEN THE DRY LOW LEVELS IN
PLACE...DRY LIGHTNING AND STRONG WINDS WILL BE POSSIBLE WITH ANY
STORMS WHICH DEVELOP THROUGH SUNDAY. MOISTURE IS EXPECTED TO
REMAIN IN PLACE THROUGHOUT MUCH OF THE UPCOMING WEEK...RESULTING
IN A CONTINUED THREAT FOR SHORES AND THUNDERSTORMS. THESE STORMS
WILL LIKELY TRANSITION FROM DRY TO WET EITHER MONDAY OR TUESDAY
AS THE LOW LEVELS CONTINUE TO MOISTEN. THIS MOISTENING WILL ALSO
RESULT IN BETTER OVERNIGHT RH RECOVERY.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...FIRE WEATHER WATCH FROM NOON SUNDAY TO MIDNIGHT MONDAY FOR
