DRY AND UNSEASONABLY WARM CONDITIONS WILL PERSIST ACROSS MOST OF THE STATE
THROUGH MONDAY BEFORE A SIGNIFICANT SHIFT TO AN ACTIVE, WET PATTERN ARRIVES
MONDAY NIGHT. A MOIST PACIFIC STORM SYSTEM WILL TRACK THROUGH IDAHO ON TUESDAY

MOUNTAIN PASSES AND RIDGES ABOVE 6,000 FEET. THE HIGHEST PRECIPITATION AMOUNTS
ARE EXPECTED IN THE CENTRAL IDAHO MOUNTAINS AND THE IDAHO PANHANDLE, WHERE
HIGH-ELEVATION SNOW ACCUMULATIONS MAY EXCEED ONE FOOT. BREEZY CONDITIONS WILL
ACCOMPANY THIS SYSTEM, WITH THE POTENTIAL FOR IMPACTFUL WIND GUSTS OF 40 TO 50
MPH ACROSS THE SOUTHERN IDAHO PLAINS AND THE PANHANDLE BY WEDNESDAY. RAINFALL
IN THE LOWER ELEVATIONS OF THE IDAHO PANHANDLE AND NORTH-CENTRAL IDAHO MAY LEAD
TO PONDING IN FIELDS AND RISES ON SMALL STREAMS THROUGH MID-WEEK. TEMPERATURES
WILL REMAIN 5 TO 10 DEGREES ABOVE SEASONAL NORMALS FOR MUCH OF THE WEEK BEFORE
A SLIGHT COOLING TREND ARRIVES BY WEDNESDAY NIGHT. UNSETTLED WEATHER WITH
LIGHTER, HIGH-ELEVATION SNOW SHOWERS WILL LIKELY LINGER INTO THE WEEKEND.
