..TRENDING DRIER AND WARMER  
 
   
BROADCAST DISCUSSION  
A GENERAL DRYING AND WARMING TREND WILL  
BRING A DECREASING THREAT OF SHOWERS AND THUNDERSTORMS INTO THE  
WEEKEND.  
   
DISCUSSION  
MOISTURE WILL CONTINUE TO DECREASE ACROSS THE AREA  
TODAY. WHILE SHOWERS AND THUNDERSTORMS ARE EXPECTED ONCE AGAIN,  
THEY WILL BE MORE ISOLATED TO WIDELY SCATTERED IN COVERAGE AND  
WILL HAVE A SMALLER POTENTIAL FOR WETTING RAIN. TONIGHT, A BRIEF  
INCREASE IN MOISTURE IS EXPECTED FOR SOUTHERN AND PORTIONS OF  
CENTRAL UTAH AS REMNANTS OF A TROPICAL SYSTEM EJECTS ACROSS THE  
DESERT SOUTHWEST AND INTO SOUTHERN UTAH, BRINGING AN AREA OF LIGHT  
TO POTENTIALLY MODERATE RAIN. MOST OF THIS MOISTURE WILL BE OUT OF  
UTAH BY TOMORROW AFTERNOON, BUT THERE WILL BE ENOUGH TO MAINTAIN  
ISOLATED TO WIDELY SCATTERED SHOWERS AND THUNDERSTORMS THROUGH THE  
AFTERNOON. OVER THE WEEKEND, MUCH DRIER CONDITIONS ARE  
ANTICIPATED, AND ANY SHOWERS WILL BE QUITE ISOLATED AND CONFINED  
TO NEAR THE HIGHER TERRAIN. AFTERNOON RELATIVE HUMIDITIES WILL  
FALL INTO THE TEENS AND LOW 20S FOR MOST VALLEY AREAS THIS  
WEEKEND. TEMPERATURES WILL ALSO GRADUALLY TREND WARMER INTO THE  
WEEKEND, ALTHOUGH NOT REACHING CLIMATOLOGICAL NORMALS UNTIL SUNDAY  
FOR MOST AREAS. NEXT WEEK, A MODEST INCREASE IN MOISTURE WILL  
BRING INCREASED SHOWER AND THUNDERSTORM ACTIVITY BACK TO THE AREA.  
HOWEVER, WETTING RAIN CHANCES WITH THESE SHOWERS ARE LIKELY TO  
REMAIN LOW.  
 
***THUNDERSTORMS IMPLY STRONG, GUSTY AND ERRATIC WINDS***
