DISCUSSION
ISSUED AT 206 AM MDT FRI AUG 7 2026
HIGH PRESSURE DIRECTLY OVER EASTERN IDAHO IS KEEPING US WARM EVEN
EARLY THIS MORNING, SO EXPECT TEMPERATURES TO BE PLENTY HOT ONCE
AGAIN THIS AFTERNOON. HEAT ADVISORY CONTINUES FOR THE SOUTH HILLS
TODAY AND TOMORROW AS HIGHS RETURN TO THE UPPER 90S AND LOW 100S.
THE NBM SHOWS A 20 TO 40 PERCENT CHANCE OF HIGHS REACHING 100
DEGREES FROM BURLEY TO POCATELLO WITH AN EVEN HIGHER CHANCE FROM
SHOSHONE TO ABERDEEN. WIND GUSTS THIS AFTERNOON CONTINUE TO BE
AROUND 20 TO 25 MPH ACROSS MUCH OF THE AREA AND WILDFIRE SMOKE STILL
FILTERS INTO EASTERN IDAHO WHERE WE STILL HAVE SOME AIR QUALITY
ALERTS IN PLACE TODAY. THIS SMOKE IS THE MAIN FOIL TO REACHING 100
DEGREES FOR SOME OF US TODAY. OVERNIGHT INTO SATURDAY, TEMPERATURES
WILL BE SLOW TO FALL, AND MANY WILL START SATURDAY IN THE MID TO
UPPER 60S. THE REST OF SATURDAY WILL BE NEARLY IDENTICAL TO FRIDAY.
ON SUNDAY, WE WILL BE JUST A FEW DEGREES COOLER AS OUR HIGH PRESSURE
RIDGE GETS FLATTENED EVERY SO SLIGHTLY. THIS HAPPENS AS TROUGHING
BEGINS TO DEVELOP OVER THE WEST COAST AS AN AREA OF LOW PRESSURE
SITS OFF THE WESTERN COAST OF BRITISH COLUMBIA EARLY NEXT WEEK. THIS
WILL GENERALLY DROP TEMPERATURES BY A COUPLE OF DEGREES EACH DAY OF
THE WEEK WITH HIGHS IN THE UPPER 80S TO LOW 90S BY WEDNESDAY AND MID
TO UPPER 80S BY NEXT FRIDAY. THIS WILL ALLOW FOR SOME ISOLATED
CHANCES OF MONSOON MOISTURE TO MAKE ITS WAY BACK INTO THE AREA.
AVIATION /18Z TAFS THROUGH 18Z SATURDAY/
ISSUED AT 1133 AM MDT FRI AUG 7 2026
ONLY AVIATION IMPACT WILL BE IF SMOKE WILL DECREASE VISIBILITY
AT ANY OF THE SITES. I DID NOT REDUCE ANYWHERE ALTHOUGH SUN IS
THE MOST LIKELY TO SEE DROP BELOW 6 MILES. SKIES CLEAR OTHERWISE
THROUGH SATURDAY MORNING. WINDS NOTHING MORE THAN 10 KNOT
DIURNAL SLOPE WINDS AT ALL SITES.
FIRE WEATHER
ISSUED AT 117 PM MDT FRI AUG 7 2026
ELEVATED FIRE WEATHER CONDITIONS ARE ANTICIPATED THROUGH THE FIRST
PART OF NEXT WEEK DUE TO THE COMBINATION OF CRITICAL MINIMUM RH
VALUES AND GUSTY WINDS. WHILE MIN RH WILL LARGELY RANGE 10 TO 15
PERCENT THROUGHOUT THE PERIOD, WINDS WILL BE MARGINAL ACROSS MUCH OF
THE REGION. CONFIDENCE IN WINDS REACHING THRESHOLD IS HIGHER ACROSS
FIRE WEATHER ZONES 475 AND 476, WHERE WIDESPREAD GUSTS TO AT LEAST
25 MPH ARE EXPECTED WITH GUSTS REACHING 30 MPH ALONG RIDGELINES.
THEREFORE, A RED FLAG WARNING HAS BEEN ISSUED FOR SATURDAY 1 PM
THROUGH 9 PM FOR THE TWO AFOREMENTIONED ZONES. WINDS WILL INCREASE
SLIGHTLY SUNDAY AND MONDAY, WHICH IS WHEN WE EXPECT MORE POCKETS OF
RED FLAG CONDITIONS TO MATERIALIZE ELSEWHERE, AS WELL. UPON
EXPIRATION, THE RED FLAG WARNING WILL NEED TO BE REISSUED TO ACCOUNT
FOR THIS EXTENDED PERIOD OF DRY AND BREEZY CONDITIONS.
PEAK WARMTH IS EXPECTED TODAY WITH TEMPERATURES WARMING INTO THE
UPPER-90S TO LOW 100S ACROSS THE LOWER ELEVATIONS. A PACIFIC TROUGH
WILL FLATTEN THE RIDGE BEGINNING SATURDAY, RESULTING IN A GRADUAL
COOL-DOWN THROUGH LATE THIS UPCOMING WEEK. DAYTIME HIGHS WILL RETURN
TO AROUND NORMAL BY MID-WEEK, TURNING COOLER THAN NORMAL LATE WEEK.
DRY CONDITIONS WILL LINGER FOR ANOTHER WEEK OR SO, WITH MODELS
INDICATING THE RETURN OF MONSOON MOISTURE BY THE LATTER HALF OF NEXT
WEEK.
AIR QUALITY
ISSUED AT 117 PM MDT FRI AUG 7 2026
AN AIR QUALITY ADVISORY REMAINS IN EFFECT THROUGH MONDAY AFTERNOON
FOR CUSTER COUNTY DUE TO AIR QUALITY THIS WEEKEND EXPECTED TO BE
"UNHEALTHY FOR SENSITIVE GROUPS."
