AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
957 AM MDT MON AUG 3 2015

.SYNOPSIS...A LOW PRESSURE SYSTEM WILL SLOWLY THROUGH NORTHERN
UTAH TODAY. A DRIER SOUTHWESTERLY FLOW WILL FOLLOW FOR
MIDWEEK...THOUGH A WEAK UPPER LEVEL DISTURBANCE WILL SCRAPE ACROSS
THE NORTHERN SECTIONS OF THE FORECAST AREA. MOISTURE MAY RETURN
LATE IN THE WEEK.

&&

.DISCUSSION...A MOIST TROUGH IS PUSHING THROUGH NORTHERN UTAH AND
SOUTHWEST WYOMING THIS MORNING...WITH WIDESPREAD STRATIFORM
RAINFALL ACROSS THE AREA. WHILE RAIN RATES HAVE GENERALLY BEEN
LOW...THE RAINFALL HAS BEEN STEADY IN MANY LOCATIONS...WITH TOTALS
OVER THE LAST 12 HOURS GENERALLY 0.2-0.5 INCHES IN MANY NORTHERN
LOCATIONS...AND IN EXCESS OF ONE INCH ACROSS SOME OF THE HIGHER
TERRAIN.

THIS STORM WILL CONTINUE TO LIFT NORTHWARD THROUGH THE DAY...WITH
STEADY RAINFALL LIKELY EXITING THE UTAH/IDAHO BORDER THROUGH THE
EVENING HOURS. AS THIS WAVE SLOWLY CLEARS THE WASATCH FRONT
THROUGH THE AFTERNOON...CONDITIONS BEHIND THE WAVE SHOULD BE
FAIRLY STABLE AND SUBSIDENT...AND THE SUN COULD EVEN COME OUT
DURING THE LATTER HALF OF THE AFTERNOON.

AS FOR THE SOUTHERN HALF OF UTAH...A SIGNIFICANTLY DRIER AIRMASS
HAS MOVED INTO THE AREA BEHIND THE TROUGH...WITH PRECIPITABLE
WATER VALUES DROPPING TO NEAR 0.5 INCHES. THAT SAID...THERE STILL
LOOKS TO BE ENOUGH INSTABILITY TO ALLOW FOR ISOLATED TO WIDELY
SCATTERED SHOWERS TO POP UP THROUGH THE AFTERNOON...ESPECIALLY
ACROSS THE CENTRAL THIRD OF THE STATE.

UPDATED THE FORECAST EARLIER THIS MORNING TO INCREASE POPS AND
REMOVE THE MENTION OF LIGHTNING ACROSS THE NORTH THROUGH THE
MORNING...AS WELL AS FILL IN MENTIONABLE POPS ACROSS THE SOUTH FOR
THE AFTERNOON TO ACCOUNT FOR THE LINGERING INSTABILITY. ALSO
ADDED SOME DETAIL TO THE AFTERNOON HOURS TO ILLUSTRATE THE QUICKLY
DECREASING POPS ACROSS THE WASATCH FRONT THROUGH THE LATER
AFTERNOON HOURS.

&&

.AVIATION...RAIN WILL CONTINUE TO IMPACT THE SLC TERMINAL THROUGH
AT LEAST 18Z...WITH CEILINGS LIKELY REMAINING AROUND 6-7KFT IN
THE STEADY RAINFALL. RAIN SHOULD PUSH NORTH OF THE TERMINAL
BETWEEN 19Z AND 22Z...AND CEILINGS WILL RAISE SIGNIFICANTLY
THROUGH THIS TIME. WINDS ARE EXPECTED TO REMAIN NORTHWESTERLY
THROUGH AT LEAST 01Z...BUT THERE REMAINS A 20 PERCENT CHANCE THAT
WINDS COULD SWITCH BACK TO THE SOUTH BETWEEN 17Z AND 21Z AS THE
LOW PRESSURE SYSTEM REMAINS TO THE NORTH.

&&

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