BOZEMAN – A slow-moving upper-level Low will bring wrap-around bands of light to moderate rainfall across SW Montana Sunday afternoon through Wednesday morning.
These wrap-around bands of moisture are highly dependent on where the Low is and how it will track to the east. This means some of you will see heavier rain and others not as much.
As of Sunday afternoon forecast models show the area of greatest concern for moderate to heavy rain will be along the Continental Divide and Rocky Mountain Front.
The National Weather Service continues a FLOOD WATCH for the Butte/Blackfoot region of SW Montana Sunday night through Wednesday morning.
The greatest potential for flooding issues will be smaller streams and creeks, urban areas with ponding on roadways, and Forest Service and county dirt roads that could be impassable.
We will continue to monitor the Flood Watch and we will update you if the watch is upgraded to a warning or advisory first on the STORMTracker Mobile Weather app and of course on the 5:30 pm and 10 pm news tonight on KXLF and KBZK.
Latest rain total forecast model through Wednesday morning.
UPDATE: The National Weather Service issued a WINTER WEATHER ADVISORY for SW Montana west of the divide or the Butte/Blackfoot region over into the Bitterroot Range above 6,500' from midnight tonight to noon on Monday.
Snow accumulations: 1"-3" above 6,500' and possibly up to 6" above 7,500'.
