FIRE WEATHER PLANNING FORECAST FOR SOUTHEAST IDAHO
NATIONAL WEATHER SERVICE POCATELLO ID
319 PM MDT WED AUG 6 2025
...RED FLAG WARNING REMAINS IN EFFECT UNTIL 9 PM MDT THIS EVENING
FOR GUSTY WINDS AND LOW RELATIVE HUMIDITY FOR FIRE WEATHER ZONES
422 AND 413...
...CRITICAL FIRE WEATHER CONDITIONS AND ADDITIONAL RED FLAG
WARNINGS FOR GUSTY WINDS AND LOW RELATIVE HUMIDITY LIKELY AGAIN
THURSDAY FOR SOME AREAS...
DISCUSSION
* CENTRAL IDAHO DISPATCH AREA WEATHER IMPACT SUMMARY (ZONES 475
AND 476)...
WINDS WILL INCREASE THURSDAY AS A LOW PRESSURE SYSTEM BRUSHES
ACROSS THE CENTRAL MOUNTAINS FROM THE NORTH AND A COLD FRONT
CROSSES THE REGION, BUT THIS SYSTEM WILL ALSO BRING AN INCREASE IN
HUMIDITY, LARGELY PRECLUDING CRITICAL FIRE WEATHER CONDITIONS.
THIS SYSTEM WILL ALSO SUPPORT THUNDERSTORMS DURING THE AFTERNOON
AND EVENING, BUT COVERAGE APPEARS ISOLATED AT THIS TIME WITH
SCATTERED COVERAGE LARGELY HOLDING NORTH OF BOTH ZONES 475 AND
476. HUMIDITY VALUES WILL TREND A BIT DRIER POST-SYSTEM FOR FRIDAY
INTO THE WEEKEND, BUT COOLER TEMPERATURES AND DECREASING WINDS
ARE EXPECTED THROUGHOUT THIS PERIOD WITH NO ADDITIONAL
THUNDERSTORMS.
* EAST IDAHO DISPATCH AREA WEATHER IMPACT SUMMARY (ZONES 410...411
AND 413)...
A LOW PRESSURE SYSTEM WILL BRUSH ACROSS EAST IDAHO FROM THE NORTH
ON THURSDAY WITH A COLD FRONT CROSSING THE REGION. SLIGHTLY HIGHER
RELATIVE HUMIDITY VALUES WILL CREEP INTO THE NORTHERN HALF OF THE
DISPATCH AREA (15-20 PERCENT), BUT THIS SYSTEM WILL ALSO SUPPORT
A SOLID INCREASE IN WINDS WHICH WILL BE CRITICAL ACROSS MOST
AREAS. IN COORDINATION WITH REGIONAL FIRE WEATHER PARTNERS...THE
BUMP IN HUMIDITY IS NOT EXPECTED TO BE ENOUGH TO SIGNIFICANTLY
REDUCE FIRE RISK GIVEN VERY DRY FUELS AND GUSTS AS HIGH AS 30 MPH
(40 MPH OVER ZONE 410), AND A RED FLAG WARNING IS LOOKING LIKELY
FOR AT LEAST ZONES 410 AND 413. THIS SYSTEM WILL ALSO SUPPORT
ISOLATED THUNDERSTORMS IN ZONE 411, BUT CONFIDENCE IN SCATTERED
COVERAGE IS LOW AT THIS TIME. HUMIDITY VALUES WILL TREND A BIT
DRIER POST- SYSTEM FOR FRIDAY INTO THE WEEKEND, BUT COOLER
TEMPERATURES AND DECREASING WINDS ARE EXPECTED THROUGHOUT THIS
PERIOD WITH NO ADDITIONAL THUNDERSTORMS.
* SOUTH CENTRAL IDAHO DISPATCH AREA WEATHER IMPACT SUMMARY (ZONES
422...425 AND 427)...
A LOW PRESSURE SYSTEM WILL BRUSH ACROSS THE AREA FROM THE NORTH
ON THURSDAY WITH A COLD FRONT CROSSING THE REGION. THIS SYSTEM
WILL BRING STRONGER WINDS REGIONWIDE (CRITICAL FOR MANY AREAS),
BUT WILL ALSO RESULT IN AN INCREASE IN MINIMUM AFTERNOON RELATIVE
HUMIDITY VALUES ACROSS ZONES 422 AND 425 (20-25 PERCENT) WHICH
MAY PRECLUDE CRITICAL FIRE WEATHER CONDITIONS. THE INCREASE IN
MOISTURE IS NOT EXPECTED TO REACH ZONE 427 HOWEVER, AND A RED FLAG
WARNING IS LOOKING LIKELY FOR THAT ZONE THURSDAY. ANY
THUNDERSTORM POTENTIAL WITH THIS SYSTEM LOOKS TO REMAIN WELL NORTH
OF THE DISPATCH AREA AT THIS TIME. HUMIDITY VALUES WILL TREND A
BIT DRIER POST-SYSTEM FOR FRIDAY INTO THE WEEKEND, BUT COOLER
TEMPERATURES AND DECREASING WINDS ARE EXPECTED THROUGHOUT THIS
PERIOD WITH NO ADDITIONAL THUNDERSTORMS.
