SHORT TERM /THROUGH MONDAY/
ISSUED AT 114 AM MDT SUN JUL 20 2025
EARLY MORNING SATELLITE IMAGERY SHOWS SOME MID TO HIGH LEVEL CLOUDS
ACROSS PARTS OF THE SNAKE PLAIN BUT MOST OF THE REGION IS VOID OF
CLOUDS CURRENTLY. THE SECOND HALF OF THE WEEKEND WILL BE VERY
SIMILAR TO THE FIRST HALF WITH ANOTHER HOT, DRY, BREEZY DAY EXPECTED
ACROSS THE REGION. AS SUCH, RED FLAG WARNINGS CONTINUE ACROSS
PORTIONS OF EASTERN IDAHO FOR LOW RHS AND GUSTY WINDS. SPEAKING OF
THE LATTER, EXPECTING WINDS IN THE 10-15 MPH RANGE FOR MANY AREAS
BUT CLOSER TO 20-30 ACROSS THE ARCO DESERT AND INTO PARTS OF THE
UPPER SNAKE PLAIN WITH EVEN HIGHER GUSTS EXPECTED. DOESN'T LOOK LIKE
PRECIP WILL BE OF MUCH CONCERN AS HI-RES CAMS ARE GENERALLY VOID OF
ANY SHOWERS/STORMS BUT THERE IS A VERY LOW CHANCE OF MAYBE SOMETHING
DEVELOPING ALONG THE MONTANA DIVIDE ALTHOUGH THIS IS TOO LOW TO BE
EXPLICITLY MENTIONED IN THE FORECAST. NOT MUCH CHANGES AS WE GET INTO
MONDAY ALTHOUGH H5 HEIGHTS ARE A TAD LOWER WITH AN UPPER TROUGH
CENTERED WELL NORTH OF THE AREA. THIS SHOULD HELP LOWER TEMPS BY A
COUPLE OF DEGREES ALTHOUGH IT WILL REMAIN BREEZY WITH THE TIGHTENED
PRESSURE GRADIENT STILL IN PLACE. TEMPS MAY DROP JUST ENOUGH TO KEEP
MIN RHS ABOVE CRITICAL THRESHOLDS FOR RED FLAG CONDITIONS BUT IT'LL
BE CLOSE. CAMS DO SHOW A BIT MORE POTENTIAL FOR SOME ISOLATED
SHOWER/STORM DEVELOPMENT DURING MONDAY AFTERNOON, NAMELY ACROSS THE
CENTRAL MOUNTAINS AND INTO THE EASTERN HIGHLANDS.
LONG TERM /MONDAY NIGHT THROUGH SATURDAY/
ISSUED AT 114 AM MDT SUN JUL 20 2025
THE EXTENDED PORTION OF THE FORECAST LOOKS RELATIVELY QUIET WITH A
TYPICAL SUMMERTIME PATTERN IN PLACE. AS THE LOW FROM MONDAY SLOWLY
MOVES NORTH INTO TUESDAY, MODELS SHOW RIDGING TRYING TO TAKE CONTROL
OVER THE AREA FOR MUCH OF THE REST OF THE WEEK. WE WILL BE ON THE
FAR WESTERN EDGE OF THE RIDGE AND WITH SW FLOW ALOFT BASICALLY INTO
THE WEEKEND, WOULDN'T BE SURPRISED TO SEE SOME WAVES OF MOISTURE
SNEAK INTO THE REGION SPARKING AT LEAST SOME ISOLATED POP CHANCES AT
SOME POINT OVER THE DAYS AHEAD. TEMPERATURES LOOK TO STAY WARM, AT
OR ABOVE AVERAGE, WHICH EQUATES TO UPPER 80S TO MID 90S FOR THE
LOWER ELEVATIONS THROUGHOUT THE UPCOMING WEEK, AND LIKELY
BEYOND.
AVIATION /06Z TAFS THROUGH 06Z MONDAY/
ISSUED AT 1044 PM MDT SAT JUL 19 2025
WINDS HAVE BACKED OFF THIS EVENING AFTER A WEAK COLD FRONT
MOVED THROUGH TODAY. WINDS WILL BE BREEZY AGAIN TOMORROW
AFTERNOON (GUSTS NEAR 15 TO 25 KTS FOR ALL TAF SITES). ALSO,
EXPECT LOW TO MID CLOUDS BY MID TO LATE AFTERNOON TOMORROW WITH
MOISTURE MOVING INTO THE AREA AHEAD OF A LOW PRESSURE SYSTEM
FORECASTED TO BE OVER THE STATE OF WASHINGTON. WINDS WILL BACK
OFF AGAIN IN THE EARLY EVENING TOMORROW.
FIRE WEATHER
ISSUED AT 114 AM MDT SUN JUL 20 2025
RED FLAG WARNINGS ARE IN EFFECT FOR ZONES 410, 413, 425, AND 427
WHERE THE COMBINATION OF DRY FUELS, GUSTY WINDS, AND LOW HUMIDITY
WILL CREATE DANGEROUS FIRE CONDITIONS. HUMIDITIES IN THESE AREAS
WILL GENERALLY BE IN THE LOW TO MID TEENS. WIND GUSTS OF 30 TO 40
MPH ARE LIKELY THIS AFTERNOON ACROSS THE SNAKE PLAIN AND MAGIC
VALLEY. GUSTS TO AROUND 25 MPH ARE LIKELY ACROSS THE SOUTHERN
HIGHLANDS.
WE COULD SEE A REPEAT PERFORMANCE ON MONDAY AFTERNOON WITH
COMPARABLE HUMIDITIES STILL IN PLACE. WINDS ARE EXPECTED TO BE AS
STRONG AND PERHAPS SLIGHTLY STRONGER.
PIH WATCHES/WARNINGS/ADVISORIES
RED FLAG WARNING FROM 1 PM THIS AFTERNOON TO 9 PM MDT THIS
