Cascades experience fresh mountain snow in May

The STORMTracker Weather Team is predicting a spring storm will drop significant amounts of rain and snow on Montana this week. Minor agricultural flooding continues in low-lying areas along the river. At 8:15 AM Wednesday, the river stage was 9.6 feet.

The National Weather Service has issued winter storm warnings and winter weather advisories for the western part of the state starting Tuesday evening and persisting through early Thursday.

WINTER STORM WARNING for most passes except Lookout along with the Butte, Anaconda, Deer Lodge, Seeley Lake, Swan Lake, Dillon and Ennis areas. Roads are expected to be mostly wet through Wednesday afternoon, though higher intensity snow showers will still have the capability to produce brief accumulations of slush on road surfaces.

With a drying and warming forecast, any threat for snow at the mountain passes will be gone by midday Wednesday. It will pick up tomorrow, especially around Colorado Springs.

The storm system we are tracking is moving through Utah and toward Colorado this afternoon. Rainfall of between one-tenth to a quarter inch leads into Wednesday and Wednesday night, when up to an inch could fall.

Wind ahead of that approaching storm can increase to 10-20 miles per hour this afternoon. Bigger rain will likely hold off until tonight.

Northwest Montana will stick to all rain through today but temperatures will be well on the cool side region-wide, with highs only topping off in the 40s and 50s. Pueblo, Cañon City, and the Southeastern Plains will warm through the mid-to-upper 70s.

Wednesday and Thursday should bring scattered showers and isolated thunderstorms with highs in the lower 60s.

Rain will begin increasing from west to east after midnight.
