DISCUSSION
ISSUED AT 210 AM MDT WED JUL 1 2026
TODAY THROUGH FRI NIGHT...WEAK UPPER LEVEL TROUGH WILL ACTUALLY
CROSS THROUGH THE FORECAST AREA TONIGHT. EXPECT CONTINUED
INSTABILITY TODAY WITH LIGHT PRECIPITATION NEARLY EVERYWHERE
EXCEPT THE BEAR LAKE REGION. THIS TROUGH IS MOVING ENE IN
DIRECTION AND SO WILL BRING MORE PRECIPITATION TO THE NORTHERN
ZONES OF THE FORECAST AREA THAN THE SOUTHERN. FOR TONIGHT AND
THU THE GREATER PRECIPITATION MOVES WITH THE TROUGH TO THE
EASTERN AND SOUTHERN HIGHLANDS. THE AMOUNT OF PRECIPITATION IS
EVEN LOWER THAN TODAY. AS THE UPPER LEVEL FLOW FLATTENS FRI, THE
LIGHT PRECIPITATION AND RISK OF THUNDERSTORMS STAYS IN THE AREAS
SOUTH OF THE SNAKE RIVER. THE AMOUNT OF SUNSHINE AND THE SLOW-
MOVING NATURE OF THIS LOW WILL MEAN A VERY GRADUAL WARMING
TREND, ON THE ORDER OF 1 TO 3 DEG F FROM DAY TO DAY. WIND IS
LIGHT TODAY, THEN BREEZIER TOMORROW AFTER THE TROUGH PASSES TO
THE EAST. BREEZY CONDITIONS CONTINUE FRI AFTERNOON AS WELL.
INDEPENDENCE DAY THROUGH TUE...AN UPPER LEVEL RIDGE CENTERED IN
THE FOUR CORNERS AREA WILL START AMPLIFYING BY SUN. THE ONLY
DIFFERENCE IN THE CLUSTERS IS HOW STRONG THIS RIDGE IS. THIS
SHOULD ALLOW SOME STRONG WARMING BY MON OR TUE, SO EXPECT
ANOTHER SURGE IN TEMPERATURES, WHERE LOW ELEVATION LOCATIONS
WILL START EXCEEDING 90 DEG F. THE OVERALL SUBSIDENCE SHOULD
KEEP SKIES NEARLY CLEAR, WITH ONLY SOME AFTERNOON CUMULUS DUE TO
DAYTIME HEATING THE ONLY WAY CLOUDS COULD DEVELOP. AS USUAL
UNDER SUCH A RIDGE, WIND WILL STAY RELATIVELY CALM AT NIGHT WITH
SLOPE- VALLEY WIND FOR THE LATE MORNING TO EARLY EVENING.
AVIATION /06Z TAFS THROUGH 06Z THURSDAY/
ISSUED AT 1044 PM MDT TUE JUN 30 2026
ALL SHOWERS AND THUNDERSTORMS HAVE ENDED FOR THE EVENING. EXPECT
VFR CONDITIONS THROUGH THE EVENING. WILL SEE PERIODS OF MID-
LEVEL CIGS BUT WELL WITHIN VFR RANGE. OTHERWISE WINDS HAVE
DROPPED OFF FOR THE EVENING.
TOMORROW EXPECT ANOTHER ROUND OF AFTERNOON INTO EARLY EVENING
SHOWERS AND THUNDERSTORMS. HAVE PUT IN VCSH AND A PROB30 FOR
TSTMS FOR ALL TAF SITES FOR LATE AFTERNOON INTO EARLY EVENING.
WINDS OUTSIDE OF THUNDERSTORMS WILL BE SLIGHTLY BREEZY WITH
GUSTS OF AROUND 15 TO 20 KTS, MAINLY FOR IDA AND PIH. EXPECT
OUTFLOWS OF AROUND 25 TO 30 KTS WITH ANY THUNDERSTORMS. WINDS
SHOULD DROP OFF BY EARLY EVENING (1 TO 2Z). THUNDERSTORM
OUTFLOWS MAY KEEP WINDS ELEVATED SLIGHTLY LATER.
FIRE WEATHER
ISSUED AT 210 AM MDT WED JUL 1 2026
WARMING AND DRYING CONTINUES TODAY. THE AIR REMAINS UNSTABLE
ENOUGH TO GENERATE AFTERNOON/EVENING SHOWERS AND THUNDERSTORMS,
BUT THE MOISTURE CONTENT SHOULD BE WAY DOWN AND HUMIDITY FOR THE
AFTERNOON SHOULD START LOWERING. WIND WILL BE LIGHT TODAY AND
THU, BUT AS THE UPPER LEVEL PATTERN FLATTENS, THE WIND SHOULD BE
STRONGER FRI. LIGHT SHOWERS AND AFTERNOON/EVENING THUNDERSTORMS
WILL DECREASE IN COVERAGE FOR THU AND FRI. BY SAT AN UPPER
LEVEL HIGH IN THE FOUR CORNERS AREA WILL BE BUILDING, AND BY SUN
OR MON TEMPERATURES IN LOWER ELEVATIONS WILL START SURPASSING
THE 90 DEG F MARK IN MANY LOCATIONS. BY MON, A THREAT OF SHOWERS
AND THUNDERSTORMS RETURNS WITH ANOTHER UPPER LEVEL TROUGH
APPROACING FROM THE WEST.
PIH WATCHES/WARNINGS/ADVISORIES
NONE.
