SHORT TERM /THROUGH SUNDAY/
ISSUED AT 146 PM MDT SAT JUL 5 2025
AFTERNOON SATELLITE IMAGERY SHOWS SOME CU DEVELOPMENT ACROSS THE
EASTERN HIGHLANDS AND UP TOWARDS THE ISLAND PARK AREA. THESE HAVE
BEEN PRODUCING SOME THUNDERSTORMS BUT GENERALLY AFTER THE ACTIVITY
LEAVES IDAHO AND PUSHES INTO MONTANA AND WYOMING. THAT BEING SAID,
CAN'T RULE SOME ISOLATED SHOWERS/STORMS IN THIS AREA OVER THE NEXT
FEW HOURS WHILE THE REST OF THE REGION IS EXPECTED TO REMAIN DRY AS
A PROLONGED PERIOD OF HIGH PRESSURE BEGINS TO SETTLE OVER THE AREA.
TEMPERATURES TODAY AND TOMORROW WILL CLIMB INTO THE LOW TO MID 80S
ACROSS THE LOWER ELEVATIONS WITH MOSTLY SUNNY SKIES EXPECTED FOR THE
SECOND HALF OF THE WEEKEND.
LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/
ISSUED AT 146 PM MDT SAT JUL 5 2025
THE WORK WEEK STARTS OFF MUCH LIKE THE WEEKEND ENDED WITH HIGH
PRESSURE IN FIRM CONTROL OF WEATHER ACROSS EASTERN IDAHO. AS H5
HEIGHTS CONTINUE TO RISE FOR THE FIRST PART OF THE WEEK, SO DO THE
TEMPERATURES WITH 90S EXPECTED TO RETURN AS EARLY AS MONDAY FOR SOME
SPOTS, NAMELY THE LOWER SNAKE AND MAGIC VALLEY. TUESDAY AND
WEDNESDAY WILL BE VERY HOT WITH MID TO UPPER 90S APPEARING LIKELY
FOR THE LOWER ELEVATIONS WITH VERY FEW CLOUDS AND NO PRECIPITATION
CHANCES EXPECTED. LATE WEDNESDAY, AND MORE SO ON THURSDAY, AN UPPER
TROUGH LOOKS TO MOVE THROUGH THE REGION AND THIS WILL HELP LOWER OUR
TEMPS A TOUCH, ALTHOUGH STILL ABOVE NORMAL, FOR THURSDAY AND FRIDAY
AND MAYBE SPARK A VERY ISOLATED HIGH ELEVATION SHOWER/STORM BUT IT
DOE S LOOK LIKE THINGS WILL REMAIN DRY. IT WILL HOWEVER INCREASE
WINDS OVER THE AREA AS THE PRESSURE GRADIENT TIGHTENS THUS
POTENTIALLY CREATING SOME FIRE WEATHER CONCERNS. THIS WILL BE
SOMETHING TO MONITOR OVER THE DAYS AHEAD. OTHERWISE, THE PATTERN
LOOKS PRETTY BLEAK FOR ANY RAIN MAKERS ACROSS THE REGION. SUMMER IS
IN FULL SWING ACROSS THE GEM STATE.
AVIATION /18Z TAFS THROUGH 18Z SUNDAY/
ISSUED AT 1110 AM MDT SAT JUL 5 2025
RESIDUAL MOISTURE AND REMNANT SHORTWAVE TROUGHING WILL KEEP
ISOLATED SHOWERS AND THUNDERSTORMS IN THE FORECAST, BUT OUTSIDE
THE RANGE OF MOST PORTS ACROSS EASTERN IDAHO TODAY. WE'RE
BEGINNING TO SEE SOME ISOLATED SHOWERS/THUNDERSTORMS POP UP OVER
THE YELLOWSTONE PLATEAU AS OF 11AM AND THIS ACTIVITY IS LIKELY
TO EXTEND ALONG THE CONTINENTAL DIVIDE AND SOUTH THROUGH THE
EASTERN HIGHLANDS THIS AFTERNOON. DIJ COULD SEE A BRIEF, GUSTY
SHOWER OR THUNDERSTORM, SO WILL CONTINUE TO CARRY THE PROB30 FOR
THIS FEATURE. ELSEWHERE, FAIR WEATHER CU MAY DEVELOP OVER SUN,
BUT NOT EXPECTING ANY THREAT TO VFR CONDITIONS. BREEZY WINDS
THROUGH THE SNAKE PLAIN WILL BRING OCCASIONAL GUSTS TO BYI, PIH,
AND IDA THROUGH THIS EVENING BUT CALMING AFTER SUNSET.
SUNDAY, HIGH PRESSURE WILL BEGIN TO TAKE OVER THE AREA WITH
CLEARING SKY CONDITIONS AND SLACKENING WINDS. VFR SHOULD REIGN.
FIRE WEATHER
ISSUED AT 146 PM MDT SAT JUL 5 2025
RESIDUAL MOISTURE FROM THE STORM ACTIVITY OVER THE LAST SEVERAL DAYS
IS GENERATING ISOLATED SHOWER AND THUNDERSTORMS THIS
AFTERNOON/EVENING. THIS ACTIVITY SHOULD REMAIN LARGELY ACROSS ZONE
411 AND THE NORTHERN PORTIONS OF ZONES 475, 476, 410 AND 413. AS
WE'VE SEEN WITH THE LAST FEW DAYS, SOME OF THE STRONGER SHOWERS AND
THUNDERSTORMS COULD HAVE SOME BRIEF GUSTY AND ERRATIC WINDS. LATEST
HREF AND HRRR GUIDANCE FAVORING THE BULK OF THE THUNDERSTORM
ACTIVITY ALONG THE ID/MT DIVIDE NEAR I-15 THIS AFTERNOON, COINCIDENT
WITH PEAK WIND GUSTS SWATHS OF 30-40 MPH EAST THROUGH THE TARGHEE
PASS AREA. OUTSIDE OF ANY THUNDERSTORM ACTIVITY, SOME ENHANCED WIND
GUST OF 20-35 MPH COULD BE FELT THROUGH SNAKE PLAIN - ZONE 410 AND
THE NORTHERN HALF OF ZONE 425. MIN RH VALUES LIKELY BOTTOM OUT IN
THE UPPER TEENS THIS EVENING, BUT SHOULD REMAIN ISOLATED ENOUGH TO
NOT NECESSITATE FIRE WEATHER HEADLINES.
SUNDAY THROUGH TUESDAY, WE'LL BEGIN TO SEE TEMPERATURES CREEP HIGHER
EACH DAY AS HIGH PRESSURE SETTLES INTO THE AREA. THE FORECAST IS DRY
UNDER MOSTLY CLEAR SKY CONDITIONS. WITH DAILY HIGH TEMPERATURES
INCREASING DAILY, WE'LL BEGIN TO SEE RH VALUES CRATER TO BELOW
CRITICAL THRESHOLDS EACH AFTERNOON/EVENING. WINDS, HOWEVER, SHOULD
REMAIN RATHER LIGHT - BELOW CRITICAL THRESHOLDS OVER THE NEXT THREE
DAYS. THE NEXT FIRE WEATHER ISSUE COULD ARISE WEDNESDAY AS THE
PRESSURE GRADIENT BEGINS TO TIGHTEN WITH A PACIFIC TROUGH NUDGING
INLAND PULLING A LITTLE MOISTURE ALONG WITH IT. THIS WILL HELP KNOCK
TEMPERATURES BACK A FEW DEGREES AND BUMP UP RHS SLIGHTLY.
