AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1000 AM MDT MON JUN 29 2015

.SYNOPSIS...HIGH PRESSURE WILL REMAIN IN PLACE ACROSS THE REGION
THROUGH THE EARLY PART OF THE WEEK. THE HIGH WILL SHIFT WESTWARD
AFTER MIDWEEK BRINGING A DRIER NORTHERLY FLOW TO THE AREA. THE
AIRMASS ACROSS THE REGION WILL REMAIN UNSEASONABLY WARM THROUGH
THE WEEK.


&&

.DISCUSSION...HIGH PRESSURE REMAINS PARKED OVER THE FORECAST
AREA...RESULTING IN CLEAR SKIES. TEMPERATURES ARE UNUSUALLY WARM
THIS MORNING...WITH SOME HIGH MIN RECORDS TIED OR BROKEN. LOOKING
AT NEAR RECORD HIGH TEMPERATURES ONCE AGAIN WITH MAXES RUNNING UP
TO 15F ABOVE SEASONAL NORMS. LOOKING AT A FEW SHOWERS AND
THUNDERSTORMS TO DEVELOP ONCE AGAIN OVER THE HIGHER TERRAIN AS THE
VALLEYS REMAIN DRY.

ORIENTATION OF THE RIDGE BECOMES MORE NW TO SE TUESDAY INTO
WEDNESDAY AS A PACIFIC NORTHWEST TROUGH MOVES OVER THE
RIDGE...ALLOWING FOR JUST A BIT OF COOLING OVER NORTHERN UTAH. THIS
WILL ALSO CAUSE SOME SHIFT IN THE MOISTURE OVER THE AREA...WHICH
COULD INCREASE COVERAGE OF AFTERNOON CONVECTION SLIGHTLY. AS THE
RIDGE AXIS REORIENTS WEST OF THE AREA WEDNESDAY
NIGHT/THURSDAY...DRIER AIR WILL MOVE BACK INTO THE FORECAST AREA.

NO UPDATES EXPECTED TO THE FORECAST THIS MORNING.

&&

.AVIATION...THE STRONG HIGH PRESSURE ALOFT ACROSS UTAH WILL MAINTAIN
CLEAR SKIES AND HOT TEMPERATURES AT THE TERMINAL DURING THE TAF
PERIOD. PREVAILING SOUTHEAST WINDS THIS MORNING WILL TURN TO THE
NORTHWEST AROUND 19Z...THOUGH WITH TEMPERATURES AT 15Z RUNNING
WARMER THAN YESTERDAY THIS WIND SHIFT COULD ARRIVE AS EARLY AS 18Z.

&&

.FIRE WEATHER...THE RIDGE OVERHEAD REMAINS NEARLY STATIONARY WITH
VERY SIMILAR CONDITIONS EXPECTED TODAY AS WHAT WE HAVE SEEN THE
PAST COUPLE OF DAYS. ISOLATED MAINLY HIGH-BASED THUNDERSTORMS OVER
THE HIGHER TERRAIN THIS AFTERNOON AND EVENING. THESE STORMS WILL
BE CAPABLE OF PRODUCING LOCAL WIND GUSTS TO 40 MPH. THE COVERAGE
OF THUNDERSTORMS WILL INCREASE TUESDAY AFTERNOON THROUGH EARLY
WEDNESDAY AS THE RIDGE FLATTENS DUE TO A DISTURBANCE MOVING ACROSS
THE NORTHERN ROCKIES. IN THE WAKE OF THIS DISTURBANCE THE RIDGE
WILL REDEVELOP TO OUR WEST WHICH WILL PLACE UTAH UNDER A DRIER
NORTHWEST FLOW BUT HOT CONDITIONS WILL PERSIST WITH MOST VALLEYS
SEEING SINGLE DIGIT MINIMUM RH LEVELS ONCE AGAIN.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
