FIRE WEATHER PLANNING FORECAST FOR SW IDAHO AND SE OREGON
NATIONAL WEATHER SERVICE BOISE ID
339 AM MDT WED SEP 23 2026
..HOT, DRY, AND BREEZY THURSDAY
..COLD FRONT FRIDAY WITH GUSTY WINDS AND SHARP COOLING
..COOLER THIS WEEKEND THRU EARLY NEXT WEEK
DISCUSSION
* SOUTHWEST IDAHO BLM (ID ZONES 400, 420, 423, 424, 426)...TEMPERATURES
WILL BE ON AN UPWARD TREND TODAY. THURSDAY WILL BE MUCH WARMER
AND THE MOST CRITICAL DAY OF THE WEEK WITH VALLEY TEMPERATURES
IN THE LOW TO MID 90S, MINIMUM RHS AROUND 15%, AND WINDS GUSTING
UP TO 30 MPH IN THE SNAKE PLAIN. A DRY COLD FRONT MOVES THROUGH
FRIDAY AFTERNOON, SO WIND GUSTS 20 TO 30 MPH THAT MORNING WILL
STRENGTHEN BEHIND THE FRONT TO 25 TO 40 MPH FRIDAY AFTERNOON.
TEMPERATURES DROP SHARPLY THURSDAY INTO FRIDAY/SATURDAY BY ABOUT
10-20 DEGREES, AND REMAIN COOLER THROUGH EARLY NEXT WEEK WITH A
WEAK SYSTEM SLATED TO MOVE THROUGH SUNDAY/MONDAY
* SOUTHWEST IDAHO FOREST (ID ZONES 401, 402, 403, 421)... DRY
CONDITIONS TODAY AS TEMPERATURES WARM. THURSDAY WILL BE THE
HOTTEST DAY IN THE FORECAST, WITH MOUNTAIN VALLEY TEMPERATURES
PEAKING NEAR 80 DEGREES. A COLD FRONT ON FRIDAY QUICKLY BRINGS
TEMPERATURES BACK DOWN TO NEAR NORMAL, WITH GUSTY WINDS EXPECTED
THAT MORNING AND EVEN STRONGER GUSTS IN THE AFTERNOON, UP TO 35
MPH ALONG RIDGES AND 25 MPH IN VALLEYS. MOST OF THE MOISTURE
WITH THIS FRONT PASSES NORTH, SO PRECIPITATION CHANCES ARE
MOSTLY LIMITED TO NORTHERN PAYETTE NF. SATURDAY WILL BE 15 TO 20
DEGREES COLDER THAN THURSDAY AFTER THE FRONT HAS MOVED THROUGH.
* SOUTHEAST OREGON (OR ZONES 670-675)... TEMPERATURES WARM SHARPLY
TOMORROW WITH MUCH OF THE AREA SEEING MAXIMUM TEMPERATURES IN
THE MID-HIGH 80S. MINIMUM RHS 10-20% ACROSS MUCH OF THE AREA AND
WIND GUSTS UP TO 20-30 MPH THAT AFTERNOON WILL ALSO CREATE
ELEVATED FIRE WEATHER CONCERNS. A COLD FRONT ON FRIDAY BRINGS
STRONG WINDS THAT MORNING AND EVEN STRONGER WINDS THAT AFTERNOON
BEHIND THE FRONT WITH GUSTS UP TO 40 MPH POSSIBLE, HIGHEST IN
SOUTHERN HARNEY AND MALHEUR COUNTIES. IN SOUTH-CENTAL AND
NORTHEASTERN OREGON, JUST ALONG THE PERIPHERY OF OUR FORECAST
AREA, THERE IS A CHANCE OF RAIN SHOWERS AS THE FRONT PASSES.
TEMPERATURES COOL 15-20 DEGREES THURSDAY INTO SATURDAY.
