Severe storms and heavy rain have been targeting the Rockies since Thursday, when large hail began battering portions of Utah and Idaho. Two tornadoes were even captured on video in Utah on Friday, including the mountainside twister you see below!

Flood Risk

Significant flooding is possible on Saturday as abundant moisture is sent upslope into eastern and central Montana, as well as eastern Wyoming. The level 3 flood risk (dark green) indicates numerous flash flood warnings are anticipated in the area, with bigger flood impacts possible, like water entering buildings or inundating vehicles.

Widespread rainfall totals of 1-2 inches are expected from western Nebraska through southern Montana, with localized totals topping 3-5 inches.

Severe Storms & Timing

Hail, wind, and tornado damage will be possible through Sunday as the upper-level low provides plenty of lift and wind shear. The I-25 corridor form eastern Wyoming into Colorado are favored for severe storms, with more intense storms just east of the corridor.

While wind is the primary hazard expected, large hail is possible along with a tornado or two. The SPC is highlighting eastern Colorado on Sunday with a low-end tornado threat.

Storms will likely be most active in the afternoons, as daytime heating provides additional energy. As the upper-level low slowly moves eastward, so will the heaviest rain and severe storm chances. A few showers will linger into Monday, but aren't likely to cause additional issues.
