Widespread haze is expected this evening and tonight, but this haze will diminish some in the northern half of the state as we go through the night as a cold front brings some cleaner air into our area. For tomorrow, it is still going to be hazy, but it is not going to be as hazy as it was today. The air quality is also going to be in the “moderate” or “good” category in most locations tonight and tomorrow.
Outside of the haze, we are going to have mostly to mainly clear skies tonight and mostly to mainly sunny skies tomorrow morning. The cloud cover is then going to increase later on tomorrow as a disturbance begins to approach our area, and the cloud cover is going to diminish from west to east tomorrow night as this disturbance leaves our area.
Tomorrow evening and early tomorrow night, there are going to be scattered showers and thunderstorms around the Helena area as this disturbance passes through. A lot of this precipitation is going to break apart as it crosses the Continental Divide though, so only isolated showers and thunderstorms are expected in north-central Montana tomorrow evening and tomorrow night.
We are also going to have refreshingly cool temperatures tonight as lows are going to be in the mid to upper 40s and low 50s in most locations. We are then going to have pleasant temperatures tomorrow as highs are going to be in the mid to upper 70s and low to mid 80s in most locations. It is also going to be a little breezy in some areas tomorrow as wind gusts up to 30 mph are possible.
