IDAHO STATE FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BOISE ID
533 AM MST TUE MAR 3 2026
WEAK HIGH PRESSURE BUILDING OVER THE REGION WILL BRING A DRY AND UNSEASONABLY
WARM DAY ON TUESDAY, WITH MANY SOUTHERN VALLEYS SEEING TEMPERATURES REACH THE
LOWER 60S. THIS BRIEF PERIOD OF CALM ENDS WEDNESDAY AS A STRONG COLD FRONT
MOVES ACROSS THE STATE, BRINGING WIDESPREAD RAIN AND MOUNTAIN SNOW.
PRECIPITATION WILL BE MOST SIGNIFICANT IN THE IDAHO PANHANDLE AND CENTRAL
MOUNTAINS, WHERE LIQUID TOTALS COULD REACH HALF AN INCH THROUGH WEDNESDAY
NIGHT. SNOW LEVELS WILL REMAIN RELATIVELY HIGH AROUND 6,000 FEET INITIALLY
BEFORE DROPPING BEHIND THE FRONT, THOUGH SIGNIFICANT ACCUMULATIONS ARE NOT
EXPECTED AT LOWER ELEVATIONS. BREEZY TO GUSTY CONDITIONS WILL ACCOMPANY THE
FRONTAL PASSAGE, WITH THE STRONGEST WINDS LIKELY ACROSS THE SOUTHERN HIGHLANDS
AND SNAKE RIVER PLAIN ON THURSDAY. A SECONDARY WARMING TREND IS EXPECTED OVER
THE WEEKEND, THOUGH MOIST NORTHWESTERLY FLOW WILL KEEP A PERSISTENT CHANCE OF
LIGHT SHOWERS IN THE NORTHERN AND CENTRAL MOUNTAINS. CONFIDENCE IS INCREASING
FOR A MORE SUBSTANTIAL SHIFT TO A COLDER AND WETTER PATTERN STATE-WIDE BY EARLY
NEXT WEEK.
