High Elevation Snow and Heavy Rain Expected in the Northwest and Southwest - 10-29 to 10-31

Updated Thu Oct 29th 2026, 8:03am PDT

We're looking at a bit of a weather roller-coaster for the rest of this week with snow in the mountains and heavy rain in different parts of the country. The Cascades and Northern Rockies are in for some snowfall Thursday into Friday. Meanwhile, the Southern High Plains and parts of the Southwest will experience heavy rain, raising concerns for flash floods. Let's take a closer look.

Snow for the Northwest

A weather system hanging around off the Pacific Northwest is pulling in moisture, which means rain and snow for the higher elevations of the Cascades and the Northern Rockies on Thursday. As the cold air moves in, snow will develop mainly over mountains, gradually easing off by Friday.

Rainy Days for the Great Lakes and Northeast

Through Thursday night, expect rain and some thunderstorms over the Upper Great Lakes, with lighter showers trickling into the Northeast by Friday.

Heavy Rain Threat in Southern Plains

Thursday into Friday, the Southern High Plains is in for a soaking, with significant rainfall potentially leading to flash flooding in vulnerable urban and rural areas. Please stay alert and check local advisories.

Wet Weather for the Southwest

Starting Friday and continuing into Saturday, the Southwest will see showers and thunderstorms, bringing heavy rain. This could lead to localized flash flooding, especially in places like Phoenix, AZ and Las Vegas, NV.

Weekend Outlook

By Saturday, the rain pattern shifts with moisture moving northward across the Great Basin, resulting in rain and mountain snow for regions like Salt Lake City, UT and Reno, NV.
