Sunny and breezy
High pressure will take over and we'll have light breezes today. Winds from SW 10-25+ mph with highs in the mid-to-upper 60's. 66 in Jackson, 70's in Salmon. A little cooler in Island Park with highs in the upper 50's. Lows tonight will still be cool, upper 30's. Tomorrow we'll have a major warm up with 80's for highs and then even more warmth for Friday with winds picking up from the south 20-35+mph. Blowing dust and haze and some will see 90 degrees + into the lower valley.
A weak disturbance Saturday will lower our temps slightly and we'll have a better chance of showers for Father's Day (30%) with highs in the mid 70's. Cooler air behind that system will settle us down into the 60's for Monday. Normal highs should have us in the mid 70's as a seasonal average.
