DIVIDE, AND ALONG THE NORTHERN WYOMING/IDAHO BORDER) COMBINED
WITH BREEZY GUSTS OF 20 TO 35 MPH AS A TROUGH MOVES THROUGH THE

EXPECT VERY DRY CONDITIONS, OVERALL LIGHT WINDS, AND WARMER
THAN NORMAL TEMPERATURES UNDER THE INFLUENCE OF HIGH PRESSURE
THROUGH THE PERIOD. TEMPERATURES WILL RISE TO AROUND 6 TO 12
DEGREES ABOVE NORMAL BY TUESDAY. A VERY WEAK WAVE/TROUGH LATE
WEDNESDAY INTO THURSDAY WILL DROP TEMPERATURES SLIGHTLY (3 TO 6
DEGREES) AND BRING AN SLIGHT UPTICK IN AFTERNOON WINDS (GUSTS OF
AROUND 20 MPH).
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.
