AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1003 PM MDT SUN MAY 24 2015

.SYNOPSIS...HIGH PRESSURE ALOFT WILL SLIDE EAST ACROSS UTAH LATE
TONIGHT THROUGH TUESDAY. A NEW PACIFIC STORM SYSTEM WILL SETTLE
INTO THE PACIFIC NORTHWEST THROUGH THE NORTHERN ROCKIES ON
TUESDAY. THIS STORM SYSTEM WILL IMPACT MAINLY NORTHERN UTAH
MIDWEEK.

&&

.DISCUSSION...AN UPPER LOW REMAINS IN PLACE OVER COLORADO AND
WYOMING THIS EVENING WHILE A SHORTWAVE DISTURBANCE IS SEEN TRACKING
SOUTH DOWN EASTERN NEVADA. SHOWERS/THUNDERSTORMS ARE STILL BEING
GENERATED NEAR AND BETWEEN THESE TWO FEATURES...AND ALSO ACROSS
SOUTHWEST UTAH AHEAD OF THE NEVADA DISTURBANCE. GENERAL WANING OF
SHOWERS CAN BE EXPECTED ACROSS THE NORTH AFTER MIDNIGHT...BUT THEY
MAY NOT COMPLETELY END AS WEAK RIPPLES CONTINUE TO ROTATE AROUND THE
CLOSED LOW. SOUTHERN UTAH IS EXPECTED TO SEE SHOWERS CONTINUE
THROUGH MUCH OF THE NIGHT UNTIL THE SHORTWAVE DISTURBANCE MOVES
THROUGH THE AREA.

HIGH PRESSURE WILL BUILD INTO THE AREA TOMORROW RESULTING IN A
CONTINUED WARMING TREND. HOWEVER...LINGERING MOISTURE WILL ALLOW FOR
CONVECTIVE SHOWERS TO DEVELOP AGAIN...ALTHOUGH THEY SHOULD BE
WEAKER AND LESS WIDESPREAD THAN THOSE SEEN TODAY.

UPDATED THE FORECAST MAINLY TO MAKE A FEW ADJUSTMENTS TO SKY/POP FOR
THE REMAINDER OF THE NIGHT.

&&

.AVIATION...NORTH TO NORTHWEST WINDS WILL CONTINUE AT THE SLC
TERMINAL THROUGH AROUND 05Z BEFORE SOUTH WINDS DEVELOP INTO THE
AREA. CIGS SHOULD RISE ABOVE 7000FT AFTER 05-06Z...BUT THERE IS A 10
PERCENT CHANCE OF ADDITIONAL SHOWERS OVERNIGHT WHICH COULD RESULT IN
OCCASIONAL CEILINGS OF ABOUT 5000-6000FT.

&&

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