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 /18Z TAFS THROUGH 18Z THURSDAY/
ISSUED AT 1114 AM MDT WED JUL 1 2026
MAIN IMPACT WILL BE THE POSSIBILITY OF SHOWERS AND THUNDERSTORMS
TODAY. HAVE PROB30 THUNDERSTORMS AT ALL TAF SITES BEGINNING 19
TO 21Z AND CONTINUING THROUGH 01-02Z. WILL SEE GUSTY WINDS NEAR
ANY THUNDERSTORMS WITH GUSTS UP TO 30 KNOTS OR GREATER.
THUNDERSTORMS WILL BE OVER BY 05Z.
FIRE WEATHER
ISSUED AT 147 PM MDT WED JUL 1 2026
THE ATMOSPHERE 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
APPROACHING FROM THE WEST.
PIH WATCHES/WARNINGS/ADVISORIES
NONE.
