AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
952 PM MDT TUE JUL 23 2013

.SYNOPSIS...DEEP MOISTURE OVER SOUTHERN UTAH WILL CONTINUE
SPREADING NORTH TONIGHT. THIS MOISTURE WILL COVER THE ENTIRE AREA
BY WEDNESDAY...AND COULD LINGER THROUGH THE UPCOMING WEEKEND.

&&

.DISCUSSION...ELONGATED HIGH PRESSURE CENTERED ACROSS FAR NORTHERN
NEVADA THROUGH CENTRAL COLORADO IS GIVING WAY TO A WEATHER
DISTURBANCE MOVING NORTH ACROSS CENTRAL NEVADA AND SOUTHERN UTAH AT
THIS TIME. MOISTURE ACROSS UTAH HAS BEEN CONFINED TO THE SOUTH FOR
MUCH OF THE DAY...BUT WITH THIS WAVE LIFTING NORTH THE ASSOCIATED
MOISTURE GRADIENT NOW EXISTS FROM AROUND THE DUGWAY AREA THROUGH
SOUTHERN UTAH COUNTY. WITH THE LOWER LEVELS REMAINING RATHER DRY
ALONG THE LEADING EDGE OF THE MOISTURE SURGE...ONLY SOME CLOUDS AND
VIRGA OR LIGHT SHOWERS ARE OCCURRING ACROSS CENTRAL UTAH. SOUTHERN
UTAH WAS ANOTHER STORY WHERE DEEPER MOISTURE ALLOWED SCATTERED
SHOWERS TODAY TO PRODUCE LOCALLY HEAVY RAIN. FORTUNATELY MOST OF
THE SHOWERS MISSED THE MOST FLASH FLOOD-PRONE AREAS...AND WITH
SHOWERS DECREASING THIS EVENING THE FLASH FLOOD WATCH HAS BEEN
ALLOWED TO EXPIRE. A FEW SHOWERS WILL LINGER THROUGH THE NIGHT FROM
SOUTHERN THROUGH CENTRAL UTAH. SOME VIRGA MAY DEVELOP ACROSS
PORTIONS OF NORTHERN UTAH TONIGHT BUT MEASURABLE RAIN IS NOT LIKELY.

AS THE AFOREMENTIONED DISTURBANCE CONTINUES TO LIFT NORTH
TOMORROW...MOISTURE WILL CONTINUE TO INCREASE ACROSS NORTHERN UTAH.
DEEPER MOISTURE ENCOMPASSING A LARGE PORTION OF THE FORECAST AREA
SHOULD RESULT IN GREATER COVERAGE OF CONVECTION TOMORROW.
HOWEVER...THUNDERSTORMS MAY INITIALLY BE DRY ACROSS THE NORTH. AS
THE WAVE PASSES...HIGH PRESSURE WILL REBOUND OVER NEVADA ON
THURSDAY. THIS WILL SPREAD A SOMEWHAT DRIER NORTHWESTERLY FLOW INTO
THE AREA THURSDAY AND INTO FRIDAY...ESPECIALLY ACROSS NORTHERN UTAH.
ALTHOUGH THUNDERSTORMS ARE STILL POSSIBLE...COVERAGE AND RAINFALL
POTENTIAL WILL BE LESS THAN WHAT IS EXPECTED FOR TOMORROW. HIGH
PRESSURE WILL SLOWLY MIGRATE EAST AGAIN WITH MOISTURE EXPECTED TO
RETURN OVER THE WEEKEND.

UPDATED FORECAST MAINLY TO ADJUST POP/SKY FOR THE REMAINDER OF THE
NIGHT.

&&

.AVIATION...VFR CONDITIONS WILL CONTINUE AT THE KSLC TERMINAL
THROUGH THE FORECAST PERIOD. SWITCH TO SOUTHEAST DRAINAGE WINDS IS
EXPECTED TO OCCUR BY 0400 UTC THIS EVENING.

&&

.FIRE WEATHER...MOISTURE WILL CONTINUE TO SURGE NORTHWARD
TOMORROW...PRESENTING THE POTENTIAL FOR DRY THUNDERSTORMS TO DEVELOP
ACROSS NORTHWESTERN UTAH...AND SO A FIRE WEATHER WATCH FOR DRY
THUNDERSTORMS IS IN EFFECT FOR ZONE 478 FOR TOMORROW AFTERNOON.
THOUGH STORMS ARE EXPECTED TO DEVELOP STATEWIDE...WITH DEEP MOISTURE
ELSEWHERE...NORTHWEST UTAH IS THE ONLY PORTION OF THE STATE
EXPECTED TO SEE DRY THUNDERSTORMS. HOWEVER...EXPECT GUSTY WINDS IN
THE VICINITY OF ANY STORMS THAT DEVELOP. A BRIEF DRYING TREND IS
EXPECTED FOR THURSDAY AND FRIDAY...BUT MOISTURE WILL RETURN ACROSS
THE STATE FOR THE WEEKEND.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...FIRE WEATHER WATCH FROM WEDNESDAY AFTERNOON THROUGH WEDNESDAY
     EVENING BELOW 7500 FEET FOR UTZ478.

WY...NONE.
