A powerful system moving over the Plains will bring the threat of severe weather to the region through the first part of the new week.
Severe thunderstorms are forecast to erupt each afternoon over part of the Plains through at least Wednesday with the focus of the storms slowly shifting east each day.
Denver, Omaha and Wichita are just a few of the cities that will be impacted by the storms before they move over the lower Mississippi Valley for the second half of the week.
Monday afternoon will bring the first round of severe storms as they develop along the Front Range of the Rocky Mountains.
Damaging winds and large hail are expected to be the primary concerns with these storms, although a few isolated tornadoes cannot be ruled out.
Thunderstorms of this nature can result in flight delays at airports, especially if they move through around the time of the evening commute.
Similar threats should be expected for Tuesday afternoon as the storms shift eastward and expand from Minnesota to the Texas Panhandle.
Of the storms that develop across this large area, those in the northern extent will likely be more intense than those farther south over Oklahoma and Texas.

This late-season severe weather will not be the only threat for the Plains as heavy rain will raise flooding concerns over the northern extent of the region.
According to AccuWeather.com Meteorologist Jordan Root, "wind-swept rain will blast areas on the north and western side of this system, mainly affecting Montana, Wyoming, and the Dakotas Tuesday through Wednesday."
Rainfall totals may top 4 inches through Wednesday in some locations in eastern Montana and western portions of the Dakotas, more than enough to cause flooding.
It is not uncommon for widespread severe weather to occur during fall months.
Even though severe weather outbreaks are not nearly as common as they are during the spring, fall is known to have the second highest number of severe weather events; more than typically occur during the summer.
"As the jet stream strengthens and dips farther south, the clashes between warm and cold air become more frequent. As a result, the potency of low pressure systems increase," said Root.
As we head into the heart of fall, the likelihood of severe weather events will increase before dropping late in the season.
