SHORT TERM...TONIGHT THROUGH MONDAY NIGHT...SHOWERS WILL
DISSIPATE QUICKLY THIS EVENING OVER HIGHER TERRAIN AS THE
ATMOSPHERE STABILIZES. WINDS WILL DIMINISH AS WELL WITH ONLY
PORTIONS OF S-CENTRAL IDAHO KEEPING A NOTICEABLE WIND OVERNIGHT.
CLEAR SKIES AND A DRYING AIR MASS WILL ALLOW FOR GOOD RADIATIONAL
COOLING, AND LOW TEMPERATURES SUNDAY MORNING WILL BE WELL BELOW
NORMAL. AN UPPER RIDGE WILL MOVE INTO THE AREA SUNDAY AND THE
ACCOMPANYING WARM FRONT WILL INCREASE CLOUDS ACROSS THE REGION
AND SUPPORT A SLIGHT CHANCE OF SNOW SHOWERS IN THE MOUNTAINS
OF NORTHERN BAKER AND ADAMS COUNTY. DRY CONDITIONS WILL PREVAIL
THROUGH MONDAY NIGHT AS THE UPPER RIDGE AXIS SHIFTS EASTWARD.
TEMPERATURES WILL WARM TO AROUND NORMAL ON MONDAY WITH SOUTHWEST
FLOW ALOFT AND GUSTY EASTERLY SURFACE WINDS ACROSS OPEN TERRAIN.
LONG TERM...TUESDAY THROUGH SATURDAY...DRY CONDITIONS THROUGH
MUCH OF OUR EXTENDED PERIOD AS A RIDGE OF HIGH PRESSURE DOMINATES
THE AREA. TEMPERATURES WILL CREEP UP TO NORMAL THEN CLIMB ABOVE
NORMAL BY THE END OF THE WEEK. AS WE HEAD INTO THE WEEKEND, MODELS
ARE STILL IN-LINE WITH BRINGING ANOTHER UPPER LEVEL TROUGH INTO
THE AREA WHICH WILL BRING PERIODS OF SHOWER ACTIVITY BACK INTO THE
FORECAST.
