Area Forecast Discussion National Weather Service Billings MT 310 AM MDT Mon Oct 18 2021

DISCUSSION. Today through Tuesday Night .

Temperatures will still warm into the 60s before a cold front swings across the area this afternoon. Cold front will be dry across the lower elevations, but a dynamic upper low over southern Wyoming will bring some moisture to the area to produce snow over the mountains, and a rain/snow mix ove the foothills. Accumulations of a few inches over northeast-facing slopes via upslope flow is expected in the Beartooth and Bighorn Mountains, especially the southern half of the Bighorns, which has a medium chance to see over 6+ inches, including Story, though a bit more uncertainty remains for them as precipitation may begin as rain. Regardless, have issued a Winter Weather Advisory for the Bighorns, with the focus on the more southern portion of the mountains. Far SE MT could also see a quick 0.1-0.25" of rain as the upper low swings east over the plains.

No arctic surge is associated with the cold front, so cooling will be as a result of the energy brought in with the upper low, so while Tuesday will be cooler, highs will still reach the 40s across the area. Only impacts of concern would be for roads in the Bighorns, but confidence is low for any lasting deterioration of road conditions due to road temperatures mostly staying above freezing. Vertz

Wednesday through Sunday .

Upper riding dominates the weather pattern for the second half of the week through the weekend. A couple weak shortwaves could cut across the area Thursday and Sunday, but only contains a very small chance for precipitation, and minimal amounts if it even occurs. There are hints of some breezy winds on the horizon for early next week, but confidence is low at this time to even attempt to give any details about it. Vertz

AVIATION.

Mountains obscurations is expected beginning Monday evening due to rain and snow, and expect a wind shift with a cold front during this evening period as well. However, all terminals should see VFR conditions over the next 24 hours. Vertz
