A FLOOD ADVISORY is in effect for many areas east of the Continental Divide including Helena, Great Falls, the Rocky Mountain Front, Lewistown, Boulder, Townsend, Bozeman, Ennis, Dillon among other areas. A FLOOD WARNING is in effect for the Missouri River in northern Fergus County. A FLOOD WARNING is in effect for the Milk River from near Saco to Nashua. A FLOOD WARNING is also in effect for the Little Bighorn River near Hardin, and I-90 has been closed from Hardin to the Wyoming border because of water over the roadway. Wow, there’s a lot going on. This first round of flooding is because of lower elevation snowmelt. Much of that snow has melted, and some of the waterways will begin to recede in the next few days. As always, there’s more active weather over the next several days. A front will move through Montana on Tuesday afternoon with a few isolated thunderstorms, showers, and mixed rain/snow in the mountains. If thunderstorms develop, they would be the first of the year for the state. It will be warmer with highs in the 50s for much of the state, eastern Montana could warm into the 60s. Wednesday will have cloud cover increasing as the next storm moves toward the state. By afternoon and evening, a mix of rain and snow will develop through western and central Montana. Precipitation will change to all snow Wednesday night. Thursday will be a snowy day with several inches accumulating mainly in southern and central Montana. Travel will be impacted with snow covered and slushy roads. Snow showers will taper off through Friday. This weekend, the final two days of March will be very nice with mainly sunny skies and highs near 50. Even though the next few days will be quite stormy, March goes out like a lamb.
