High pressure continues to create nice weather for a couple of days in East Idaho. A system will show up late tomorrow and forecast changes to cooler temperatures, down from the upper 70's to 81 Thursday, to mid 60's for Friday. Chances for showers/storms is 30%-40% for weekend and only low to mid 50's for highs.
Today will be pleasant with winds N 5-10 and mid 60's to 70 around Salmon, Pocatello. It will be clear and you'll need sunglasses. Winds will pick up tomorrow evening from WSW 20+mph and gusty around mountain storms. We have a slight chance of showers with the Thursday front, into Friday. Worst weather is for the weekend, with a cold rain chance.
