There are going to be some scattered rain showers and thunderstorms around this evening and early tonight, generally in locations south and west of Great Falls, as some monsoonal moisture works its way into our area. We are also going to have partly to mostly cloudy skies around this evening, then we are going to have decreasing clouds tonight. For tomorrow, we are going to have increasing clouds throughout the day with some scattered rain showers and thunderstorms around during the afternoon and evening as an upper-level trough sends some moisture into our area. Also, most of the thunderstorms that do develop today and tomorrow are going to be non-severe, although frequent lightning, heavy rainfall, gusty winds, and small hail are still possible with any thunderstorms that do develop.
As we head into this weekend, there is a slight chance that we could see a couple rain showers and thunderstorms during the PM hours, but most locations are going to remain dry. We are also going to have mostly to mainly sunny skies this weekend.
It is also going to continue to be very hot tomorrow and this weekend as high temperatures are going to continue to be in the mid to upper 90s and low 100s in most locations. Because of this heat, a Heat Advisory remains in effect for central Montana until 9pm tomorrow, and an Excessive Heat Warning remains in effect for eastern Montana until 9pm on Saturday. Thankfully, even though it is going to be hot during the day, at least we are going to continue to get some relief from the heat at night as lows are generally going to be in the upper 50s and low to mid 60s for the next four nights.
