DISCUSSION
ISSUED AT 103 AM MDT SUN JUL 26 2026
BIG PICTURE PATTERN FOR THE FIRST HALF OF THE WEEK IS A RIDGE
OF HIGH PRESSURE CENTERED OVER THE SOUTHERN ROCKIES WHICH IS
SENDING MONSOON MOISTURE OUR WAY. MEANWHILE, AN UPPER LEVEL
TROUGH IS PRESSING INTO THE PACIFIC NORTHWEST. WE'RE IN THE
MIDDLE BETWEEN THESE TWO FEATURES. THIS KEEPS A THREAT FOR
AFTERNOON AND EVENING STORMS GOING THROUGH THE FIRST HALF OF THE
WEEK WITH THE SOUTHEAST HIGHLANDS WITH THE BETTER CHANCES FOR
ISOLATED TO SCATTERED STORMS. WE ALSO REMAIN MILD IF NOT HOT
WITH TEMPS IN THE MID 90S AND POSSIBLY APPROACHING TO 100 AS THE
NBM HAS BEEN UNDERPERFORMING ON HIGHS THE PAST FEW DAYS. SO THE
HEAT ADVISORY CONTINUES THROUGH TODAY AT LEAST. EXPECT BREEZY
CONDITIONS ACROSS THE CENTRAL MOUNTAINS INTO THE UPPER SNAKE
RIVER PLAIN WITH THE UPPER TROUGH TRYING TO PRESS INTO THE
RIDGE. WE ARE WATCHING SMOKE POTENTIAL FROM THE OREGON
WILDFIRES. HRRR SMOKE MODEL SHOWS SOME SMOKE MOVING BACK INTO
THE MAGIC VALLEY THIS MORNING AND RETREATING FOR THE AFTERNOON.
POTENTIALLY, A BIGGER SURGE OF NEAR SURFACE SMOKE FOR MONDAY
WHICH COULD EXTEND INTO THE SNAKE PLAIN.
LOOKS LIKE THE TROUGH PASSES THROUGH THURSDAY AND THE MONSOONAL FLOW
DIMINISHES. WE STILL REMAIN UNDER THE INFLUENCE OF THE RIDGE FOR
LATE WEEK INTO THE WEEKEND. BUT IT LOOKS DRIER WITH FEWER CLOUDS SO
THAT MAY ALLOW OUR TEMPS TO RISE BACK TOWARDS 100, ASSUMING THEY
BACK OFF SOME EARLY TO MID WEEK.
AVIATION /12Z TAFS THROUGH 12Z MONDAY/
ISSUED AT 103 AM MDT SUN JUL 26 2026
SOME MORNING SHOWERS CAN BE FOUND AROUND SUN/BYI. OTHERWISE,
THE THREAT FOR STORMS TODAY LOOKS MAINLY CONFINED TO SOUTHEAST
IDAHO, PERHAPS ENCROACHING UPON PIH, IDA AND DIJ THIS AFTERNOON.
MOST LIKELY NOT ON STATION HOWEVER. OTHERWISE 20KT GUSTS
POSSIBLE AROUND PIH AND IDA THIS AFTERNOON.
FIRE WEATHER
ISSUED AT 103 AM MDT SUN JUL 26 2026
ISOLATED STORMS WILL CONTINUE THIS AFTERNOON MAINLY ACROSS THE
CENTRAL MOUNTAINS AND SOUTHEAST HIGHLANDS. GUSTY OUTFLOW WINDS
ARE POSSIBLE ONCE AGAIN WITH STORMS. NEAR CRITICAL WINDS/RH
EXIST THIS AFTERNOON ACROSS THE CENTRAL MOUNTAINS INTO THE SNAKE
RIVER PLAIN. COULD BE NEAR CRITICAL CONDITIONS FOR WIND AND RH
ONCE AGAIN ON MONDAY FOR THE SAME AREAS.
