Today could be the hottest day of the year for a number of locations. Areas around Libby and Eureka will be close to 100, with the Missoula Valley, Thompson Falls, Plains, and the St. Regis/Superior areas reaching the upper 90s. Butte hasn't recorded a 90 degree day for 2014, but we will be close today with the forecast calling for highs in the upper 80s. Bozeman and much of Southwest Montana will be around 90 degrees. A light shower is possible near Yellowstone, but we will be quite dry across the region.

A few changes are expected Tuesday. An approaching storm system will bring the threat of showers and thunderstorms. Temperatures will remain hot. Highs will be in the mid to low 90s for areas north of I-90 with highs in the mid to upper 80s for Butte and Bozeman.

The thunder threat remains Wednesday as waves of moisture move across the state. Temperatures will be slightly cooler with highs in the 80s area wide.
