UNSETTLED WEATHER CONTINUES THROUGH MID-WEEK AS A COOL UPPER-LEVEL TROUGH
REMAINS OVER THE REGION. SCATTERED RAIN AND SNOW SHOWERS, ALONG WITH A FEW
AFTERNOON THUNDERSTORMS, WILL IMPACT THE CENTRAL MOUNTAINS AND EASTERN IDAHO
THROUGH WEDNESDAY. A WARMING AND DRYING TREND BEGINS THURSDAY AND CONTINUES
THROUGH FRIDAY AS HIGH PRESSURE BUILDS ACROSS THE STATE. BY THE WEEKEND,
TEMPERATURES WILL RISE 10 TO 15 DEGREES ABOVE NORMAL, WITH LOWER VALLEYS IN
SOUTHERN IDAHO POTENTIALLY REACHING THE UPPER 70S TO LOW 80S. CONFIDENCE
DECREASES FOR THE SECOND HALF OF THE WEEKEND AS A NEW SYSTEM POTENTIALLY BRINGS
A RETURN OF SHOWERS AND THUNDERSTORMS, PRIMARILY TO SOUTHERN AND CENTRAL
IDAHO. BEYOND THE 7-DAY PERIOD, OUTLOOKS FAVOR A TRANSITION BACK TOWARD COOLER
AND WETTER CONDITIONS FOR MUCH OF THE STATE.
