In the wake of powerful thunderstorms that targeted portions of the central Rockies, Front Range and High Plains over the weekend, additional rounds of thunderstorms will target areas east of the Rockies through Monday night.
During the day on Saturday, powerful thunderstorms targeted portions of Utah, Colorado and Wyoming, producing damaging wind gusts and large hail. Winter Park, Colorado, located just west of Denver and sitting at a little over 9,100 feet reported a wind gust of 110 mph on Saturday. Winds in Denver gusted to 78 mph as the powerful thunderstorms blew through. Many other cities reported very impressive wind gusts as well as storms rolled through on Saturday.
In total on Saturday, there were over 300 damaging wind reports across the United States, most of which occurred in Wyoming, Colorado, western Nebraska and western South Dakota.
Sunday brought another round of violent thunderstorms, this time farther
east. Large hail, damaging winds and even a few tornadoes were reported
across the central and eastern Dakotas.

A similar threat for severe weather will extend right into Monday night across portions of the Plains and Upper Midwest as well.
The atmospheric setup for thunderstorm activity into Monday night will be very similar to the events that occurred on Sunday, as an area of low pressure exits out of the Rockies and sparks thunderstorm activity across portions of the Plains and Upper Midwest.
Damaging winds, large hail and isolated tornadoes will all be threats with the strongest thunderstorms.
Cities at risk for severe weather Monday into Monday night include Sioux Falls, South Dakota, Grand Island and North Platte, Nebraska, and even northward into places like St. Cloud, Minnesota.
"June and July are the prime months for severe storms over the northern tier of the U.S. and the southern tier of Canada," AccuWeather Senior Meteorologist Brett Anderson said.
"This is because the jet stream has finally retreated to the north, and this area often represents a zone of marked temperature and humidity contrast," he explained.

A wet pattern is expected to continue into the day on Tuesday as moisture from Cristobal tracks northward into portions of the Midwest. While widespread severe weather is not expected this day, there can be isolated tornadoes that are spawned by Cristobal's circulation.
After rounds of heavy rainfall through Monday, there will be an increased risk for river flooding and damage to some farmland due to an abundance of rain.
Strong wind gusts, with and without thunderstorms, are likely to become the legacy with Cristobal around the lower Plains and Great Lakes regions.
Once Cristobal lifts northward into Canada into the day on Wednesday, the threat for thunderstorms and heavy rain will diminish greatly across the Plains and Upper Midwest. From mid- to late week, a dry, seasonable and a rather breezy forecast is in store for the region.
There will be a severe weather risk farther to the east over the Ohio Valley, Great Lakes and central Appalachians, however.
