AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1007 AM MDT WED MAY 29 2013

.SYNOPSIS...A SERIES OF PACIFIC STORM SYSTEMS WILL BRING A COOL 
PATTERN TO THE REGION THROUGH FRIDAY WITH SOME MOISTURE OVER THE 
NORTH. HIGH PRESSURE WILL BUILD INTO THE AREA FOR THE WEEKEND
BRINGING A WARMING TREND.


&&

.DISCUSSION...THE FIRST PACIFIC TROUGH IN THE SERIES IMPACTING THE
AREA HAS MOVED INTO CENTRAL WYOMING THIS MORNING...WHILE THE
SECOND ONE IS CURRENTLY MOVING OVER NEVADA. UTAH IS IN A TEMPORARY
PRECIPITATION LULL BETWEEN THE TWO SYSTEMS...BUT ACTIVITY OVER
NORTHERN UTAH WILL INCREASE THIS AFTERNOON AS THE SECOND TROUGH
MOVES IN. PRECIP SHOULD BE MORE SCATTERED IN NATURE THAN
YESTERDAY...AND THE TEMPORARY CLEARING WILL ALLOW FOR WARMER TEMPS
THAN YESTERDAY...THOUGH MAXES WILL STILL BE AROUND 5F BELOW CLIMO
OVER THE NORTH AND MORE SEASONABLE IN SOUTHERN UTAH.

REINFORCING WAVES WILL CONTINUE TO IMPACT NORTHERN UTAH ON
FRIDAY...KEEPING CONDITIONS UNSETTLED. HOWEVER...MOISTURE WILL BE
DECREASING DURING THAT TIME SO PRECIP COVERAGE SHOULD BE LESS WITH
EACH WAVE. HIGH PRESSURE IS STILL EXPECTED TO MOVE IN SATURDAY
THROUGH EARLY NEXT WEEK...RESULTING IN A QUICK WARMING AND DRYING
TREND. 

UPDATES THE FORECAST EARLIER TO ADJUST POPS FOR TODAY AND TONIGHT
FOR CURRENT TRENDS. NO ADDITIONAL UPDATES PLANNED. 

&&

.AVIATION...SOUTHEASTERLY WINDS AT KSLC ARE EXPECTED TO SWITCH BACK 
TO NORTHWEST BY 18Z BUT COULD DELAY UNTIL 19Z. THERE IS A 40 PERCENT 
CHANCE OF CIGS LOWERING BELOW 7K FT AGL BETWEEN 21 AND 01Z DUE TO 
SHOWERS AND ISOLATED THUNDERSTORMS.
