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.
