As we move on to the last day of September we do so ending the month on a cool and cloudy note. Highs today will peak in a range of 50's and 60's with times of sunshine but also potential for rain and thunderstorms into the afternoon. Heavy rainfall is to be seen for the Northeastern corner of the state with the Black Hills seeing Aerial Flood Advisories in effect for much of the day due to heavy rain showers pushing through that region.
Tonight: Lows falling into the 30's and 40's will make for an evening to bundle up before heading out. As lows fall below freezing at upper elevations snowfall accumulation will become possible from the Yellowstone Region East over into the Bighorns. Meanwhile, lower elevations will continue to see scattered showers and a few early evening thunderstorms.
Wednesday: An even cooler day than today as we roll into October. Lows will only peak in the 40's and 50's under sustained cloud cover and more rain potential and even snowfall possible in those higher elevations. Keep cozy with winds breezy again to give those already cool temperatures a bit of an extra chill.
Looking Ahead: Today and tomorrow's cool and cloudy weather will give way to a much more favorable forecast to head outside later in the week. Highs will boost back into the 60's for Thursday under mostly sunny to sunny skies before peaking back in the 70's into the weekend, starting Saturday, and into your next work week.
