AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
910 PM MDT THU JUL 27 2006

.SYNOPSIS...HIGH PRESSURE TO OUR WEST THIS EVENING WILL MOVE OVER THE
AREA FRIDAY AND THEN TO OUR EAST SATURDAY. MOISTURE WILL INCREASE
AGAIN OVER THE WEEKEND AS SOUTHWEST FLOW DEVELOPS ON THE WEST SIDE
OF THE HIGH.

&&

.DISCUSSION...THE HIGH REMAINS CENTERED TO OUR WEST THIS EVENING AND
HAS SPREAD A MUCH DRIER AIRMASS INTO THE STATE DROPPING DEWPOINTS
20 DEG F OR MORE IN THE LAST 24 HRS. THERE IS A SHARP MOISTURE
BOUNDARY ACROSS THE SOUTHWEST CORNER WITH DEWPOINTS STILL IN THE 50S
AND 60S THERE. CONVECTION THIS AFTERNOON WAS PRETTY MUCH CONFINED TO
THE MOIST AIR AND ALONG THE DRY BOUNDARY.

LARGE FIRES IN NORTHERN NV ARE PRODUCING BIG SMOKE PLUMES THAT ARE
SPREADING INTO NRN UT THIS EVE. THIS HIGH LEVEL SMOKE WAS VISIBLE
ALONG THE WASATCH FRONT AT SUNSET AND MAY WORK ITS WAY INTO LOWER
LEVELS OVERNIGHT AND TOMORROW AS THE HIGH CENTER MOVES OVERHEAD AND
THE FLOW ALOFT BECOMES LIGHT.

THE HIGH SHIFTING EAST WILL ALSO ALLOW MOISTURE FROM SOUTHERN NV TO
SPREAD NORTH TOMORROW AFTERNOON WITH DRY CONVECTION POSSIBLE BY
LATE IN THE DAY OVER NORTHWEST UT AND IN THE WEST DESERTS.

THE RIDGE AXIS REMAINS SW-NE ACROSS SRN UT THRU SAT HOWEVER SO A
DEEP MOISTURE SURGE WILL HAVE TO WAIT UNTIL THE RIDGE RE-CENTERS
OVER CO AND THAT SHOULD HAPPEN BY MON.

CURRENT PACKAGE CAPTURES THESE TRENDS AND NO UPDATES PLANNED.

&&

.FIRE WEATHER...NORTHWEST FLOW HAS DRIED THE AIRMASS AS THE RIDGE
REMAINS WEST OF THE AREA. RIDGE CENTER WILL SLIDE OVER THE AREA
FRIDAY SUPPRESSING CONVECTION BUT MOISTURE MOVING IN BEHIND THE RIDGE
COULD CREATE ISOLATED DRY THUNDERSTORMS OVER WESTERN DESERT PORTIONS
BY EVENING. ADDITIONAL DIURNAL CONVECTION IS EXPECTED EACH DAY
THROUGH THE WEEKEND...WITH STORMS STAYING ON THE DRY SIDE. STORMS
WILL BECOME WETTER ON MONDAY.

&&

.AVIATION...THE NORMAL NIGHTTIME DOWN VALLEY WIND PATTERN IS EXPECTED
TO DEVELOP TONIGHT BY AROUND 04Z AND LAST UNTIL ABOUT 18Z FRIDAY
WHEN THE LAKE BREEZE RETURNS.

&&

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