BILLINGS — Haze and smoke from regional fires has been moving over Montana and Wyoming on Saturday, but scattered showers and thunderstorms have, too. We'll have a reduction in the active weather as the sun goes down this evening, but there will still be areas of haze and smoke. Lows will remain in the mild 50s and lower 60s.
After a fairly quiet Sunday morning, we can expect showers and thunderstorms to spawn over the mountains in the afternoon, and move eastward over the lower elevations in the afternoon and evening. Be mindful for dangerous lightning if you have outdoor plans. Thunderstorms will be possible on Monday, but they won't be as likely as Sunday.
A strong ridge of high pressure will then build over the northern Rockies on Tuesday and Wednesday, and our highs will be 8-15 degrees above average in the mid to upper 90s with some lower 100s possible. Another trough of low pressure will help cool us late next week, falling back to the lower 80s with a slight chance of thunderstorms.
