AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1003 PM MDT MON MAY 25 2015

.SYNOPSIS...A MOIST AND UNSTABLE AIRMASS WILL REMAIN IN PLACE
ACROSS THE REGION. THE NEXT STORM SYSTEM WILL IMPACT MAINLY
NORTHERN AND CENTRAL UTAH THROUGH MOST OF THE REMAINDER OF THE
WEEK.

&&

.DISCUSSION...THE SHORTWAVE RIDGE THAT WAS OVER UTAH THIS AFTERNOON
IS SHIFTING EAST THIS EVENING AHEAD OF A SLOWLY ADVANCING UPPER LOW
CURRENTLY CENTERED OVER NORTHEAST WASHINGTON STATE. SHOWERS THAT
DEVELOPED TODAY WERE MOSTLY OWING TO LINGERING MOISTURE AND SOME
INSTABILITY AIDED BY DAYTIME HEATING. A FEW OF THESE PRODUCED
LOCALLY HEAVY RAIN...BUT MOST OF THESE STORMS HAVE DIMINISHED WITH
NIGHTFALL.

HOWEVER...WESTERN/CENTRAL UTAH WILL SEE INCREASED DEVELOPMENT OF
SHOWERS OVERNIGHT...AND SOME HAVE ALREADY BEGUN...AS A SHORTWAVE
DISTURBANCE CURRENTLY OVER WESTERN NEVADA CONTINUES TO TRANSLATE
EAST. STILL SEEING A LARGE AREA OF COOLER CLOUD TOPS ASSOCIATED WITH
THESE STORMS OVER EASTERN NEVADA. ALTHOUGH THESE STORMS WILL TREND
WEAKER WITHOUT THE SURFACE HEATING ELEMENT...NAM/HRRR/RAP ALL
SUGGEST THE SHORTWAVE WILL STILL MAINTAIN ENOUGH ENERGY TO PRODUCE
PRECIPITATION INTO UTAH. AS SUCH HAVE UPDATED TO INCREASE POPS
TONIGHT.

THE SHORTWAVE DISTURBANCE WILL CONTINUE THROUGH EASTERN UTAH
TOMORROW...OTHERWISE WILL SEE UTAH BECOME INCREASINGLY UNDER THE
INFLUENCE OF THE CLOSED LOW TOMORROW WITH ASSOCIATED INCREASE IN
SHOWER ACTIVITY EXPECTED.

&&

.AVIATION...SOUTH WINDS WILL BECOME ESTABLISHED AT THE SLC TERMINAL
BY 05Z. EXPECT PREVAILING VFR CONDITIONS UNDER MID/HIGH CLOUDS
THROUGH MUCH OF THE NIGHT...BUT CIGS NEAR 5-7KFT WILL BECOME MORE
LIKELY AFTER 10-12Z.

&&

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