AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
839 PM MDT MON JUL 7 2014

.SYNOPSIS...HIGH PRESSURE WILL REMAIN THE DOMINANT FEATURE ACROSS
THE INTERIOR WEST THIS WEEK. MOISTURE POOLED ACROSS SOUTHERN UTAH
AND ARIZONA WILL RETURN NORTH BEGINNING LATE TUESDAY...AND SPREAD
ACROSS THE ENTIRE FORECAST AREA FOR THE LATTER HALF OF THE WEEK.

&&

.DISCUSSION...THE STRONG RIDGE ACROSS THE INTERIOR WEST REMAINS IN
PLACE THIS EVE. THE RIDGE AXIS EXTENDS FROM NWRN NV TO WRN CO BUT IS
STARTING TO ROTATE CLOCKWISE AND THE WESTERN END IS BEGINNING TO
SHIFT EAST.

CONVECTION WAS ACTIVE AGAIN TODAY WITH THE HEAVIEST RAIN ACROSS
THE SWRN CWA. RAINFALL AMOUNTS WITH THE STRONGEST STORMS SEEMED A
LITTLE LESS THAN THE LAST COUPLE OF DAYS THO AND SURFACE
DEWPOINTS HAVE FALLEN SOMEWHAT TODAY. THERE WAS A MORE NWWD DRIFT
TO THE STORMS TODAY CONFIRMING THAT THE RIDGE IS SHIFTING.

STORMS WERE ALSO ACTIVE OVER THE EAST HOWEVER IN SPITE OF THE
LOWER SURFACE DEWPOINTS AND THE GOES PRECIPITABLE WATER IMAGERY
DOES INDICATE HIGHER PW OVER THE EAST TODAY...ALTHO MOST OF THESE
WERE LIKELY ON THE DRY SIDE. THE STRONGER ACTIVITY HAS DISSIPATED
AS OF THIS EVE BUT SOME LIGHT HIGH BASED SHOWERS PERSIST ACROSS
THE SRN AND ERN CWA...AND COULD CONTINUE OVERNIGHT. HEAVIER
SHOWERS OVER NWRN AZ SHOULD REMAIN SOUTH OF THE CWA ALTHO THEY
COULD CLIP SWRN WASHINGTON CO IF THEY HOLD TOGETHER THRU MIDNIGHT.

THE RIDGE IS STILL FORECAST TO BECOME MORE N-S ORIENTED OVER THE
NEXT 24 HRS AND SHIFT EAST AFTERWARDS ALLOWING DEEPER MOISTURE TO
SPREAD NWD THRU NV AND INTO SWRN UT TOMORROW AND UP THRU THE REST
OF UT TOMORROW NIGHT INTO WED. IN ADDITION THE WEAK CIRCULATION
CENTERS THAT HAVE BEEN IN AZ ARE FORECAST TO LIFT NWD THRU THE
WESTERN SIDE OF THE HIGH BRINGING SOME ADDITIONAL LIFT. SO MOIST
CONVECTION SHOULD BECOME WIDESPREAD ACROSS THE CWA BY WED.

THE STRONGEST OF THESE CENTERS IS FORECAST TO LIFT THRU THE CWA
THU NIGHT INTO FRI WITH DRIER AIR SPREADING IN FROM THE SW IN ITS
WAKE.

FOR NOW...UPDATED FORECASTS TO LOWER CONVECTIVE COVERAGE TO
ISOLATED FOR THE REST OF THE NIGHT AND MADE A FEW ADJUSTMENTS TO
SKY COVER. NO ADDITIONAL UPDATES PLANNED BUT WILL CLOSELY MONITOR
THE CONVECTION CURRENTLY TO OUR SOUTH.

&&

.AVIATION...THE SLC TERMINAL WILL SEE VFR CONDITIONS THROUGH THE
NIGHT UNDER CLEAR SKIES. NORTHWEST WINDS ARE EXPECTED TO SHIFT
TO THE SOUTHEAST BETWEEN 03Z AND 05Z.

&&

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