The first week of spring will bring a dramatic swing in temperatures, on the order of 20-40 degrees, to the central United States.
The upswing in temperatures will cause record highs to be challenged during the first half of the new week, while the return of colder air will likely set the stage for snow to sweep from the northern Rockies to the Upper Midwest at midweek.
"As is expected in the spring, a volatile pattern is shaping up through the new week across the central U.S.," AccuWeather Meteorologist Ed Vallee said.
"After some chillier air this weekend, a dome of high pressure will control the weather through midweek. This will usher in much warmer air with some places experiencing high temperatures nearly 30-40 degrees higher than this weekend."
Highs across most of the north-central states will trend from the 30s and 40s on Saturday to the 60s and 70s early in the new week.
In the southern Plains, temperatures will swing from the 50s and lower 60s with the threat for an overnight freeze this weekend to the 70s and 80s. Some communities in the southern High Plains will even flirt with or crack the 90-degree mark.
The warmth will erase the snow that recently whitened Denver and will challenge record highs in Pueblo, Colorado; Dodge City, Kansas; Oklahoma City; and Amarillo and Lubbock, Texas.
As quick as the warmth makes a comeback, cooler air will be advancing southward.
"A developing area of low pressure across the Plains will drag a cold front through the central U.S. Wednesday and Thursday, stifling the burst of warmth," Vallee said.
Along the northern fringe of the low, windswept snow will likely emerge from the northern Rockies and track to the Upper Midwest. While the snow should initially melt, slippery travel will still unfold as the snow falls heavy enough to overcome the strong March sun and road surfaces cool.
Rapid City, South Dakota, is among the communities that could see 70-degree warmth fade to snow and highs in the 30s at midweek.
The cold front will also have to be monitored for returning severe thunderstorms and flooding downpours to the south-central states.
"While likely not as chilly as this weekend, high temperatures to end the week [in the south-central states] will likely be 10-20 degrees lower than what they will be at midweek," Vallee said.
As is typical of spring, an end to the temperature roller coaster for the Plains should not come by the new weekend.
