High pressure over the area makes for more heat today with light winds shifting to the SW 5-10 and picking up tomorrow 20-30mph. Highs will be around 90 - 88 for Idaho Falls and 92 for Pocatello.
Hotter tomorrow and busting into the 90's and even mid 90's for Pocatello, with those hot winds.
A cooling trend will blast through for Wednesday taking temperatures in the mid 80's and partly to mostly sunny conditions. It will be a long dry warm set of days until July 4th weekend. A slight shower chance hits just before July 4th Monday with some relief from 90 degree temperatures dropping temps into the upper 80's for the holiday.
