Scattered Thunderstorms Thursday evening and Friday, Heat Watch for Next Week

For our Thursday evening, look for scattered thunderstorms and gusty winds. High pressure building over the region this weekend and next week, will lead to highs close to 100°. The National Weather Service has issued a Excessive Heat Watch for Tuesday afternoon (6/29/2021) through Thursday evening (7/1/2021).

Tonight, chance of thunderstorms and gusty winds with a low into the mid 50's.

Friday, increasing clouds and winds for the afternoon hours. A chance of thunderstorms with highs into the lower to mid 80's.

Saturday, mostly sunny with highs into the lower to mid 80's, gusty winds and a few thunderstorms possible in our local mountains near Yellowstone and Grand Teton National Parks.

Sunday, Highs close to 90° for the Snake River Plain.

EXCESSIVE HEAT WATCH IN EFFECT FROM TUESDAY AFTERNOON THROUGH
THURSDAY EVENING:

  • WHAT…Dangerously hot conditions probable. Expect daytime
    temperatures in lower elevations to climb into the 100s, and mid
    to upper 90s in higher elevations. Overnight lows in the 60s
    will be common in many areas. Record highs for June are expected
    to break, and all time record highs may be threatened. Streaks
    of consecutive days at or above 100 may be threatened as well.
    The heat may last through the July 4th weekend.
  • WHERE…A great portion of Southeast Idaho including Mud Lake,
    INL, Craters of the Moon NM, Idaho Falls, Rexburg, St. Anthony,
    Pocatello, Blackfoot, American Falls, Shelley, Fort Hall,
    Albion, Almo, Malta, Rockland, Holbrook, Inkom, McCammon,
    Downey, Lava Hot Springs, Malad, Preston, Thatcher, Howe, Arco,
    Mackay, Chilly, Borah Peak, Challis, Clayton, Stanley, Ketchum,
    Sun Valley, Galena, Copper Basin, Hailey, Bellevue, and Picabo
  • WHEN…From Tuesday afternoon through Thursday evening.
  • IMPACTS…Extreme heat and humidity will significantly
    increase the potential for heat related illnesses,
    particularly for those working or participating in outdoor
    activities.
  • ADDITIONAL DETAILS…While the forecast daily highs may
    fluctuate slightly before the heat settles in, confidence
    remains very high in a long-duration unseasonal heat event. Very
    hot daytime high temperatures will combine with extremely warm
    overnight lows to exacerbate heat stress.
