AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
400 PM MDT FRI JUN 26 2015

.SYNOPSIS...HIGH PRESSURE WILL STRENGTHEN ACROSS THE REGION
THROUGH THE WEEKEND...AND REMAIN OVER THE WESTERN STATES THROUGH
NEXT WEEK.


&&

.SHORT TERM (THROUGH 06Z TUESDAY)...HIGH PRESSURE WILL REMAIN
ALMOST DIRECTLY OVER UTAH THROUGH MONDAY BEFORE SHIFTING EVER SO
SLIGHTLY TOWARDS THE WEST. SOME HIGH-MID LEVEL MOISTURE SPREADING
NORTHWARD ON THE WEST SIDE OF THIS HIGH PRESSURE WILL MOVE AROUND
THE PERIPHERY AND SEEP A LITTLE UNDER THE HIGH AS WELL DURING THE
NEXT SEVERAL DAYS. THIS WILL INCREASE THE CHANCE FOR HIGH BASED
THUNDERSTORMS OVER THE HIGHER TERRAIN BUT STILL REMAIN ISOLATED AT
BEST THROUGH SUNDAY. THIS ISOLATED COVERAGE MAY STILL REMAIN INTO
MONDAY BUT CONFIDENCE LOW SO LEFT THE SLIGHT INCREASE ALONE FOR
NOW.

HAVE INCREASED TEMPERATURES JUST A TAD EACH DAY IN MOST AREAS AS
THE 850 MB TEMPS AND 700 MB TEMPS BOTH SUPPORT THIS WARMING. THE
ONLY FACTOR THAT MAY HAVE AN IMPACT ON KEEPING TEMPERATURES FROM
RISING WILL BE ADDITIONAL CLOUD COVER WHICH DOES NOT LOOK TO BE
MUCH OF A CONCERN THROUGH SUNDAY OR MONDAY.

.LONG TERM (AFTER 06Z TUESDAY)...THE CENTER OF THE MID LEVEL RIDGE
IS FORECAST TO DRIFT WESTWARD DURING THE MIDDLE PORTION OF NEXT
WEEK...ALLOWING SLIGHTLY COOLER AIR TO SPREAD SOUTH INTO NORTHERN
UT ALONG WITH PERHAPS AN UPTICK IN MID AND HIGH LEVEL MOISTURE.
NONETHELESS 700MB TEMPS NEAR OF 17-18C TUESDAY INTO
WEDNESDAY...AND EVEN INTO THURSDAY...WILL CONTINUE TO SUPPORT
MAX TEMPS AT OR JUST ABOVE 100F ALONG THE WASATCH FRONT. WITH THE
GRADUAL INCREASE IN MOISTURE SHOULD SEE A GRADUAL UPWARD TREND IN
HIGH BASED CONVECTION DURING THE MIDDLE TO LATTER PORTION OF NEXT
WEEK.

&&

.FIRE WEATHER...A BROAD DOME OF HIGH PRESSURE WILL PREVAIL ACROSS THE
REGION INTO THE MIDDLE OF NEXT WEEK. THERE WILL BE A SLIGHT
INFLUX OF MID TO HIGH LEVEL MOISTURE. THIS WILL BRING A THREAT OF
HIGH BASE THUNDERSTORMS WITH VERY LITTLE CHANCE OF ANY WETTING
RAINS. WILL NEED TO MONITOR CLOSELY AS ANY SUBTLE DISTURBANCE NOT
FORECAST BY THE CURRENT MODELS COULD CAUSE AN INCREASE IN
LIGHTNING ACTIVITY.

&&

.AVIATION...VFR CONDITIONS WILL CONTINUE AT KSLC THROUGH THE TAF
PERIOD AND BEYOND. NORTHWEST WINDS ARE EXPECTED TO RETURN TO THE
SOUTH AROUND 04Z.

&&

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