..TRENDING DRIER AND WARMER THROUGH THE WEEKEND
 
 
   
BROADCAST DISCUSSION
 
MOISTURE FROM THE REMNANTS OF A TROPICAL  
SYSTEM WILL MOVE OUT OF THE AREA THIS MORNING, BUT ENOUGH WILL  
LINGER TO MAINTAIN A FEW SHOWERS AND THUNDERSTORMS THIS  
AFTERNOON. PRECIPITATION AND WETTING RAIN CHANCES THEN DECREASE  
THROUGH THE WEEKEND, WITH TEMPERATURES TRENDING BACK NEAR TO  
SLIGHTLY ABOVE NORMAL BY NEXT WEEK.  
   
DISCUSSION
 
A BRIEF INCREASE IN MOISTURE ASSOCIATED WITH THE  
REMNANTS OF A TROPICAL SYSTEM WILL CONTINUE TO BRING WIDESPREAD,  
MOSTLY LIGHT TO OCCASIONALLY MODERATE RAIN ACROSS SOUTHERN THROUGH  
EAST-CENTRAL UTAH THIS MORNING. AS THIS SYSTEM MOVES OUT OF THE  
AREA DURING THE AFTERNOON, THE AIRMASS WILL SLOWLY TREND DRIER  
AGAIN. HOWEVER, ENOUGH MOISTURE WILL LINGER TO PRODUCE ISOLATED  
TO SCATTERED SHOWERS AND THUNDERSTORMS OVER THE AREA THIS  
AFTERNOON, WITH SOME OF THE STRONGER STORMS CAPABLE OF PRODUCING  
WETTING RAIN. THE DRYING TREND WILL THEN CONTINUE THROUGH THE  
WEEKEND INTO THE BEGINNING OF NEXT WEEK, WITH PRECIPITATION  
BECOMING MUCH MORE LIMITED. DURING THIS DRYING TREND, RELATIVE  
HUMIDITIES WILL TREND DOWNWARD, WITH AFTERNOON MINS INTO THE MID  
TO LOW TEENS IN MANY VALLEY AREAS BY SUNDAY AND MONDAY.  
TEMPERATURES WILL ALSO TREND WARMER, BUT AFTERNOON MAXES ONLY  
REACH CLIMATOLOGICAL NORMALS BY SUNDAY. MOISTURE LOOKS TO INCREASE  
AGAIN TUESDAY OR WEDNESDAY, BUT NOT SIGNIFICANTLY. THIS WILL  
RESULT IN INCREASED CHANCES FOR SHOWERS AND THUNDERSTORMS, BUT  
WETTING RAIN CHANCES LOOK TO REMAIN LOW AT THIS TIME.  
 
***THUNDERSTORMS IMPLY STRONG, GUSTY AND ERRATIC WINDS***  
***ALL WINDS ARE 20 FOOT, 10-MINUTE AVERAGES***
