KEY MESSAGES

- Near to below normal temperatures Tuesday through Friday. Periods of light rain/snow possible (20-50%) tonight through Friday. - Even colder air arrives Friday night with the potential for the first significant snowfall of the season across the area through Sunday. Stay tuned if you have Holiday weekend travel plans!

- Another round of winter weather is possible next week, stay tuned!

UPDATE

Temperatures are dropping below freezing this evening with overnight lows forecast in the teens to 20s, coldest over far eastern Montana. While cloud cover will gradually increase from the west tonight as our next weather system approaches, mostly clear skies over far eastern Montana may allow patchy freezing fog to develop. Look for any fog that does develop to lift shortly after sunrise.

The next aforementioned weather system is expected to move through the region Wednesday, bringing light to moderate snow to portions of south-central Montana and northern Wyoming. While a bit of uncertainty remains on the exact location of the snowfall, overall forecast accumulations have not changed much this evening, with generally a trace to a couple tenths of an inch forecast. Impacts look to remain little to none, but periods of reduced visibility are possible, so those traveling should still stay aware as wintry conditions could develop. Look for the snow to gradually taper off from west to east through the afternoon, coming to an end by Wednesday evening. Arends

AVIATION

Light snow is expected to move through south-central Montana and northern Wyoming Wednesday. With this, occasional reductions to MVFR can be expected, with localized IFR under heavier snow. Mountain obscurations will occur at times. Look for the snow to taper off through the afternoon before coming to an end Wednesday evening. Behind the snow, VFR conditions will prevail.

Otherwise, patchy freezing fog is possible around KBHK tonight. Look for any fog that does develop to lift shortly after sunrise. Arends
