AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
337 PM MDT SAT MAY 4 2013

.SYNOPSIS...A SLOW MOVING STORM SYSTEM WILL BRING UNSETTLED
CONDITIONS AT TIMES THIS WEEKEND THROUGH MUCH OF NEXT WEEK WITH
SEASONABLE TEMPERATURES.

&&

.DISCUSSION...THE LOW PRESSURE SYSTEM THAT WAS OVER SOUTHERN IDAHO
THIS MORNING HAS RETREATED INTO NORTHERN NEVADA AND WILL MOVE
OFFSHORE ALONG THE CALIFORNIA COAST BY TOMORROW MORNING. CUMULUS
IS BUBBLING OVER THE HIGHER TERRAIN AND A FEW ECHOES ARE POPPING
UP ON THE RADAR...PRIMARILY OVER NORTHERN UTAH. HOWEVER...BEST
MOISTURE AND INSTABILITY REMAINS NORTH OF THE AREA.
STILL...EXPECTING SOME SHOWER ACTIVITY THROUGH THE EARLY
EVENING...BUT NOT SURE HOW MUCH PRECIP WILL HIT THE GROUND.

WITH THE EXIT OF THE LOW...SEEING AN E/NE GRADIENT STARTING TO
DEVELOP OVER NORTHERN UTAH AND SOUTHWEST WYOMING. EXPECT TO SEE
THIS CONTINUE TO STRENGTHEN INTO THE EVENING...RESULTING IN THE
POTENTIAL FOR DOWNSLOPE WINDS FOR THE NORTHERN WASATCH FRONT AND
CACHE VALLEY. BELIEVE THESE WILL REMAIN BELOW ADVISORY CRITERIA
BUT ARE WORTH NOTING.

AS THE LOW SPINS ALONG THE CALIFORNIA COAST TOMORROW...EJECTING
SHORTWAVES WILL KEEP INSTABILITY OVER THE AREA RESULTING IN SOME
WIDELY SCATTERED CONVECTION OVER THE HIGHER TERRAIN. SOUTHERLY
FLOW IS PROGGED TO DEVELOP BY MONDAY AS THE STORM SYSTEM MOVES
BACK ONSHORE...AND THIS WILL DRAW A BIT OF TROPICAL MOISTURE INTO
THE AREA. MODELS INDICATE PWS WILL BE IN EXCESS OF 0.5 FOR PARTS
OF THE CWA BY MONDAY AFTERNOON...APPROACHING THE 75TH PERCENTILE
FOR MOISTURE FOR THIS TIME OF YEAR. WITH CONTINUED
INSTABILITY...AT LEAST SCATTERED CONVECTION LOOKS LIKE A GOOD BET
AND HAVE RAISED POPS ACCORDINGLY.

THE LOW IS EXPECTED TO MOVE SLOWLY ACROSS THE SOUTHWEST UNITED
STATES THROUGH MUCH OF THE WEEK...KEEPING AN UNSTABLE AIRMASS IN
PLACE. HOWEVER...GLOBAL MODELS AGREE THAT THE FLOW ALOFT WILL
BECOME MORE NORTHERLY BEGINNING WEDNESDAY WHICH WILL DRY OUT THE
AIRMASS SOME...SO MONDAY AND TUESDAY LOOK LIKE THE DAYS WHERE
SHOWERS AND THUNDERSTORMS WILL BE MOST WIDESPREAD. HOWEVER...THINK
THERE IS AT LEAST SOME SHOT OF CONVECTION THROUGH DAY 7.

&&

.AVIATION...VFR CONDITIONS WILL PREVAIL WITH SCATTERED CLOUDS AROUND
7000-8000 FEET AGL AND ANY CEILINGS REMAINING ABOVE 10 KFT
THROUGHOUT THE TAF PERIOD. LIGHT NORTHERLY WINDS WILL WORK AROUND TO
SOUTHEAST LATER THAN USUAL...AFTER 06-08Z. THERE IS A 10 PERCENT
CHANCE THAT AN ISOLATED THUNDERSTORM COULD BE NEAR THE AIRFIELD.

&&

.FIRE WEATHER...THE UPPER LOW CURRENTLY OVER EXTREME NORTHWEST
NEVADA WILL WILL CONTINUE WEST TO A POSITION OFF THE NORTHERN
CALIFORNIA COAST BY SUNDAY. SCATTERED CONVECTION TO THE NORTH AND
EAST OF THE LOW WILL GENERALLY STAY TO THE NORTH OF THE FIRE
DISTRICT THIS EVENING.

THE POSITION OF THE UPPER LOW NEAR THE CALIFORNIA COAST ON SUNDAY
WILL CREATE A SOUTHERLY FLOW INTO THE GREAT BASIN..AND RESULT IN
INCREASE MOISTURE ACROSS THE REGION FRO EARLY IN THE UPCOMING WEEK.
THE FIRST DECENT THREAT FOR CONVECTIVE PRECIP WILL ARRIVE LATE
SUNDAY...WITH CONVECTION INCREASING IN AREAL COVERAGE DURING THE
EARLY PORTION OF THE WEEK. THE LOW WILL TURN EAST MONDAY NIGHT...
THEN TRACK ACROSS THE SOUTHERN AND CENTRAL PORTIONS OF UTAH LATE
TUESDAY NIGHT THROUGH WEDNESDAY. WIDESPREAD PRECIP WILL DEVELOP
NORTH AND EAST OF THE LOWS TRACK...WITH AREAS OF CENTRAL AND
NORTHEAST UTAH LIKELY TO SEE THE GREATEST AMOUNTS OF PRECIP.

THE EASTWARD MOVEMENT OF THE UPPER LOW COULD SLOW A BIT DURING THE
LATTER HALF OF THE WEEK. THIS SLOWING COULD END UP KEEPING SCATTERED
SHOWERS ACROSS MAINLY SOUTHERN AND EASTERN UTAH...WITH MORE ISOLATED
COVERAGE FOR THE REMAINDER OF THE STATE.

&&

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