A dry front will move from west to east across the state, kick up the wind, and hold the temperatures back five to ten degrees. The passing front will shift wind directions which will help alleviate smoke and haze. As of 7:30 AM, many locations south of Helena air quality fluctuate from UNHEALTHY FOR SENSITIVE GROUPS to UNHEALTHY. The winds are expecting to gusts up to 40 mph at times, and the high temperatures will cool to the 70s in western Montana but remain in the low 80s in central Montana; ahead of the front, eastern Montana highs will stay in the 90s. The combination of wind, hot temperatures, and very low humidity will elevate fire conditions.
Wednesday is the first day of September which is Meteorological Fall. Meteorological seasons are simply broken up based on the annual temperature, whereas Astronomical seasons are based on the position of Earth in relation to the sun. Fall-like temperatures will take us through the first few days of September.
Thursday will be a comfortable day. The high temperatures will be a few degrees warmer, the state will have plenty of sunshine, and the wind will blow comfortably from the north.
Have a great day.
