AN UNUSUALLY COLD PACIFIC LOW PRESSURE SYSTEM FOR THIS TIME OF YEAR WILL BRING
A STRONG COLD FRONT THROUGH IDAHO TODAY. WINDY CONDITIONS AND ISOLATED
THUNDERSTORMS ON THIS AFTERNOON ACROSS THE SOUTHERN HALF OF THE STATE WILL
BRIEFLY INCREASE FIRE WEATHER CONCERNS. RED FLAG WARNINGS ARE IN EFFECT FOR
AREAS OF SOUTHERN IDAHO TODAY. HOWEVER, MUCH COLDER WEATHER, INCREASED
HUMIDITY, AND RAIN IS EXPECTED TO SIGNIFICANTLY REDUCE FIRE WEATHER CONCERNS BY
SATURDAY AS THE PACIFIC LOW BECOMES CENTERED OVER IDAHO. EXPECT PERIODS OF
RAIN AND A FEW THUNDERSTORMS ON SATURDAY AND SUNDAY IN MOST AREAS OF THE STATE
WITH ACCUMULATING SNOW IN THE HIGH MOUNTAINS OF CENTRAL IDAHO AT ELEVATIONS
ABOVE 6500 FEET. THE PACIFIC LOW PRESSURE SYSTEM WILL WEAKEN AND MOVE AWAY FROM
THE AREA BY MONDAY AND TUESDAY USHERING IN A WARMING TREND AND DRIER WEATHER
ACROSS THE SOUTHERN HALF OF THE STATE, WHILE COOLER AND SHOWERY WEATHER
CONTINUES ACROSS THE NORTHERN HALF OF THE STATE.
