DISCUSSION
ISSUED AT 1208 PM MDT THU JUL 2 2026
WE ARE STILL SEEING THESE SMALL RIPPLES IN THE PATTERN HELPING
KICK OF POCKETS OF SHOWERS AND THUNDERSTORMS. FOR TODAY, IT
STILL APPEARS THE SOUTH HILLS/ALBION MOUNTAINS, EASTERN, AND
SOUTHEAST HIGHLANDS ARE THE TARGET. A FEW STORMS ARE ALSO
POSSIBLE FROM MACKAY THROUGH GILMORE SUMMIT AND LONE PINE. THERE
IS 30-50% CHANCE FOR GUSTS OVER 35 MPH THROUGH THIS EVENING. WE
CONTINUE TO DRY OUT, BUT WITH RESIDUAL MOISTURE LEFT OVER FROM
ALL OF THE RECENT MOISTURE, THERE IS THE POTENTIAL FOR SOME
HEAVIER STORMS TO PRODUCE SOME DECENT DOWNPOURS. WE MAY SEE A
FEW STORMS ACROSS THE SNAKE PLAIN, ESPECIALLY WITH ANY OUTFLOW
BOUNDARIES THAT EMERGE FROM HIGHER TERRAIN. OUTSIDE OF STORMS,
WE ARE EXPECTING SOME GUSTS OUT ACROSS THE LAVA BEDS, CRATERS,
AND THE INL AROUND 25-30 MPH. EVEN IF WE SEE A BIT OF MID LEVEL
MOISTURE TONIGHT, IT DOESN'T LOOK LIKE WE WILL SEE AND LIGHT
RAIN OR SPRINKLES AND LIKELY JUST SOME VIRGA. FOR FRIDAY, IT
LOOKS VERY SIMILAR TO TODAY'S POTENTIAL PATTERN FOR ANY SHOWERS
AND STORMS ACROSS CENTRAL AND EASTERN IDAHO. TEMPERATURES WILL
CONTINUE TO SLOWLY CLIMB, WITH MID 70S TO MID 80S TOMORROW.
FOR THE FOURTH, WE ARE STILL LOOKING AT NO STORMS DEVELOPING,
BUT WE WILL PROBABLY SEE A BIT OF VIRGA. AT THE MOMENT, ANY
STRONGER WIND GUSTS ASSOCIATED WITH THAT IS ALMOST ZERO AT THE
MOMENT. OVERALL WIND GUSTS SHOULD BE 15-25 MPH, MOSTLY DURING
THE AFTERNOON/EARLY EVENING, AND STRONGEST ACROSS RIDGELINES AND
ACROSS THE ARCO DESERT.
FOR SUNDAY AND BEYOND (AND WELL TIMED), WE ARE BACK INTO THE
POTENTIAL FOR SOME THUNDERSTORM POTENTIAL STARTING SUNDAY. AS
HIGH BECOMES RE-ESTABLISHED AROUND THE FOUR CORNERS, THAT ALLOWS
FOR A MONSOON-TYPE PATTERN TO EMERGE AND SEE SOME MOISTURE NORTH
INTO IDAHO. TEMPERATURES WILL CONTINUE TO WARM UP, MORE 90S IN
THE FORECAST, ALONG WITH OVERALL DRIER CONDITIONS. THAT MEANS IF
AND WHERE WE SEE THUNDERSTORMS, THE OVERALL PATTERN WILL BE
DRY, OR AT LEAST LIGHT RAIN-PRODUCING STORMS. THIS ALSO MEANS
MOST DEVELOPMENT WILL OCCUR ACROSS TERRAIN, WITH MORE ISOLATED
COVERAGE ACROSS THE SNAKE PLAIN AND MAGIC VALLEY, MINUS ANY TYPE
OF OUTFLOW-INDUCED STORMS. TOWARD THE END OF NEXT WEEK, THERE IS
DECENT SIGNAL IN THE GFS, ECMWF, AND THE CLUSTER FORECASTS FOR
HIGH PRESSURE TO SETTLE IN TO OUR SOUTH. THE QUESTION IS HOW FAR
WEST DOES IT BUILD AND CUT OFF ANY MOISTURE. MOST INDICATIONS
THAT WE END UP IN WEST OR SOUTHWEST FLOW. SOUTHWEST FLOW WOULD
BE WARMER AND DRY WITH MAYBE STILL LIMITED MOISTURE IMPACTING
US. MORE WESTERLY WOULD BE A BIT COOLER (RELATIVE TO THE OTHER
SCENARIO) BUT DEFINITELY DRY. BOTH PATTERNS WOULD BE BREEZY.
AVIATION /00Z TAFS THROUGH 00Z SATURDAY/
ISSUED AT 550 PM MDT THU JUL 2 2026
EXPECT VFR CONDITIONS FOR ALL TAF SITES THROUGH THE PERIOD.
SHOWERS AND THUNDERSTORMS ARE CURRENTLY WELL SOUTH OF BYI AND PIH
AND WELL NORTH DIJ. HAVE REMOVED ALL MENTION OF SHOWERS AND
THUDNERSTORMS FOR ALL TAF SITES FOR THE REST OF THE DAY. WINDS
ARE STILL ELEVATED FOR KIDA WITH GUSTS OF 20 TO 25 KTS. EXPECT
WINDS TO DROP OFF IN THE NEXT COUPLE OF HOURS. ALSO, EXPECT SKIES
TO BECOME MOSTLY CLEAR OVERNIGHT. TOMORROW AFTERNOON EXPECT CLOUD
REDEVELOPMENT WITH SHOWERS AND THUNDERSTORMS MAINLY WELL SOUTH OF
BYI, PIH, IDA AND DIJ. DIJ AND, TO A LESSER DEGREE, PIH HAVE THE
BEST CHANCE OF VICINITY SHOWERS TOMORROW AFTERNOON. HAVE VCSH FOR
DIJ ONLY CURRENTLY FOR TOMORROW AFTERNOON. WIND WILL BECOME
SLIGHTLY BREEZY TOMORROW AFTERNOON WITH GUSTS OF 10 TO 15 KTS FOR
MOST TAF SITES.
FIRE WEATHER
ISSUED AT 125 PM MDT THU JUL 2 2026
CONVECTIVE ACTIVITY THIS AFTERNOON AND EVENING WILL BE FOCUSED
ON AREAS FROM THE SNAKE RIVER SOUTHWARD. ON FRI, IT COULD BE
MORE SPREAD OUT THANKS TO A TROUGH PUSHING THROUGH CANADA THAT
HAS ENOUGH INFLUENCE THIS FAR SOUTH TO TRIGGER SOMETHING. THE
MAIN PROBLEM AREA WILL LIKELY BE THE NORTHEAST CORNER OF THE
FIRE WEATHER AREA OF RESPONSIBILITY. HIGH PRESSURE WILL DOMINATE
THE HOLIDAY WEEKEND, WARMING TEMPERATURES AND DRYING HUMIDITY.
AFTERNOON HUMIDITY GOING BELOW 15 PERCENT WILL BE LIMITED TO
ARES OF THE SNAKE RIVER PLAIN AND EASTERN MAGIC VALLEY FOR TODAY
AND FRI. THE SURGING TEMPERATURES ON INDEPENDENCE DAY WILL
SPREAD THE DRYNESS TO THE HIGHER ELEVATIONS IN THE SOUTHERN
HIGHLANDS AND SOUTHEAST HIGHLANDS. THE VERY DRY CONDITIONS WILL
CONTINUE TO EXPAND TO HIGHER ELEVATIONS WITH THE OVERALL
SUBSIDENCE.
TEMPERATURES MAY LEVEL OFF FROM THU TO FRI AFTER WARMING FROM
YESTERDAY TO TODAY, BUT STRONGER WARMING RETURNS FOR SAT WITH
PEAK TEMPERATURES LIKELY TO BE MONDAY WITH MOST LOW ELEVATION
HIGH TEMPERATURES IN THE 90S SUNDAY THROUGH NEXT THURSDAY.
NOT MUCH RISK OF WIND GUSTING TO 25 MPH UNTIL TUE AFTERNOON
WHEN THE UPPER LEVEL WIND GETS A CHANCE TO INCREASE.
PIH WATCHES/WARNINGS/ADVISORIES
NONE.
