As southwest surface winds return, we can expect the shallow cooler airmass to quickly mix out as we head into the work week.
1115 PM CST Sat Nov 15 2025 - Cooler and breezy weather tonight as temperatures drop back into the 30s to upper 20s. It has been another warm November day with temperatures in the 60s to lower 70s, despite a weak cold front moving through this morning and gusty NW winds between 25-35 mph. Cooler temperatures are expected for tomorrow with highs in the upper 40s to mid 50s (north to south); high pressure in control will lead to mainly sunny skies and NW winds will hold between 10-20 mph.
-IG /Issued 830 PM MST Sat Nov 15 2025/ - Meteorological Overview: Slight ridging moving in this afternoon has helped pushed out morning precipitation. The main concern overnight tonight is relative humidities raising near or at 100% and light winds along the Hi-line/northern Chouteau County will produce freezing fog. Areas that get dense freezing fog may develop icy spots on pavements and cause hazardous driving conditions. Weakening forcing aloft combined with warmer temperatures aloft will keep precipitation and mountain snow light overall.

Climate averages for highs this time of year rapidly drop from the mid 30s (today) to near freezing for over the 7 day period for reference.
Cooler temperatures and breezy winds will be on tap for this afternoon, and much of the upcoming work-week. Our forecast still has only the highest mountain tops receiving measurable snowfall, and most of that falling between 5 AM MST and 5 PM MST today. Any snowflakes that mix down closer to 7000-7500' likely won't stick with the above freezing surface temperatures. Monday will be mostly quiet weather-wise as the current storm system moves to the northeast, but another low pressure system is forecast to quickly follow. This more noticeable dip in afternoon temperatures will be thanks to the stronger low pressure system moving south along the California Coast.
