SHORT TERM...TODAY THROUGH FRIDAY NIGHT...ANOTHER ACTIVE DAY ON  
TAP TODAY, WITH SHOWERS AND THUNDERSTORMS EXPECTED. DEEP AND MOIST  
SOUTHERLY FLOW REMAINS IN PLACE OVER THE REGION, WITH MONSOON  
MOISTURE STREAMING IN. SURFACE DEWPOINTS HAVE CLIMBED SOME 25-30  
DEGREES SINCE EARLY TUESDAY, AND SOUNDING DATA INDICATES THAT THE  
MID LEVELS OF THE ATMOSPHERE HAVE MOISTENED SIGNIFICANTLY. SHOWERS  
HAVE CONTINUED OVERNIGHT, AND THERE IS STRONG MODEL CONSENSUS THAT  
ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS WILL OCCUR LATER TODAY,  
WITH A FOCUS OVER IDAHO. THE BEST CHANCE FOR STORMS WILL BE THIS  
AFTERNOON AND EVENING, AND SOME STORMS MAY PRODUCE GUSTY WINDS AND  
HEAVY RAINFALL. BY EARLY THURSDAY THE FOCUS OF PRECIPITATION WILL  
SHIFT EASTWARD OVER EASTERN IDAHO, WITH LINGERING  
AFTERNOON/EVENING SHOWERS POSSIBLE OVER THE HIGHER TERRAIN OF  
CENTRAL AND SOUTH CENTRAL IDAHO. TEMPERATURES WILL BE NEAR NORMAL  
TODAY, BEFORE REBOUNDING TO SLIGHTLY ABOVE NORMAL AREA-WIDE FOR  
THE REMAINDER OF THE WORK WEEK.  
 
LONG TERM...SATURDAY THROUGH WEDNESDAY...THE VERY WARM UPPER LEVEL  
HIGH PRESSURE RIDGE OVER THE INTERMOUNTAIN REGION AND GREAT PLAINS  
WILL MAINTAIN ABOVE NORMAL TEMPERATURES THROUGH THE PERIOD. MONSOON  
MOISTURE CIRCULATING IN THE RIDGE WILL FEED ISOLATED AFTERNOON AND  
EVENING THUNDERSTORMS EACH DAY, MAINLY OVER THE CENTRAL IDAHO  
MOUNTAINS AND ALONG THE NEVADA BORDER.
