The first half of the week will be dry, very warm, and breezy will bring elevated fire weather concerns for Blaine/Fergus counties Monday, and Southwest MT/North-Central MT Wednesday in areas that did not have a sufficient greenup from recent dry conditions. Be sure to avoid creating sparks. #MTwx

Later this week, hot and dry conditions turn a little bit more active and “cooler”. Daily chances for precipitation returns Wednesday through the end of the week. Uncertainty remains in exact details of how the weather evolves each day, but expect chances of showers/thunderstorms capable of producing gusty winds Wednesday/Thursday along with general breezy winds through the rest of the week. #MTwx

Highs this week will be in the 70s and 80s with the potential for highs reaching the low 90s on Wednesday. While the air temperature might be hot, our area lakes and rivers are still running fast and cold from snowmelt. Stay safe while recreating on the water and always wear a life jacket! Visit weather.gov/safety/coldwater to learn more about how to protect yourself from cold water hazards.

Hot and dry conditions are expected to persist over central and southwestern Montana this the week. Many everyday things can spark wildfires. Keep ignition sources far away from dry vegetation, wood and other fuel. Be aware of weather conditions. Always follow burn bans & local, state, and federal regulations.
