ENOUGH MOISTURE AND INSTABILITY EXISTS FOR A SLIGHT CHANCE (15-20%)
OF THUNDERSTORMS ACROSS THE BAKER VALLEY AND BURNS BLM THIS EVENING.
OTHERWISE, IT WILL BE TURNING COOLER AND UNSETTLED THE REST OF THE WEEK
AS AN UPPER LEVEL LOW SITUATED OFF THE COAST MOVES SLOWLY INLAND AND

DEGREES BELOW NORMAL WITH INCREASING CHANCES OF PRECIPITATION. WARMER
AND DRIER CONDITIONS ARE EXPECTED SATURDAY WITH ANOTHER WEATHER SYSTEM
