KEY MESSAGES

- Weather system brings precipitation (rain/snow) and breezy winds to the area today into early Wednesday.

- Light snow accumulations possible over the lower elevations, with a few inches forecast over the higher hills and down along the mountains and foothills of southern Montana and northern Wyoming.

- Unsettled conditions continue Thursday into the weekend.

UPDATE

Wet snow continues to slide southeast over northern and eastern portions of the area this morning with area webcams showing moderate to heavy snow in places. Raised snow amounts a bit over the northeast given latest radar and guidance trends. As a result, have added in Northern Rosebud, Treasure and Custer counties into the Winter Weather Advisory through this evening. Greatest snow amounts will generally be south of I-94 in these areas. The rest of the forecast remains on track. STP
