The central United States remains under the influence of an active weather pattern, with heavy rains, flash flooding, and severe weather continuing to pose potential threats.
Southern Texas and much of Florida are experiencing sustained heat, while interior California valleys are beginning to see a rise in temperatures.
Meanwhile, cooler than usual conditions are forecasted for the midsection of the country and much of the East.
In the coming days, the central U.S. will experience continued weather activity, starting with thunderstorms potentially bringing heavy rains, localized flash floods, and severe weather to portions of the Southern Plains, particularly Oklahoma and Texas on Tuesday and Wednesday.
As a strong frontal boundary moves eastward into the Northern to Central High Plains by late Wednesday into Thursday, the focus of the active weather will shift northward to areas like eastern Montana, eastern Wyoming, and northeast Colorado, before spreading into the Northern to Central High Plains. These regions can expect severe weather, heavy rain, and isolated flash flooding.
By Thursday, attention will return to the south, covering parts of the Central and Southern Plains including eastern Nebraska, much of Kansas, Oklahoma, and northern Texas. Additional heavy rains, flash floods, and severe thunderstorms are anticipated in these areas.
The ongoing active weather pattern will keep temperatures below average across much of the central U.S. due to cloud cover and rainfall. However, hot temperatures persist in southern Texas and parts of Florida, with record highs possible in South and Southwest Florida over the next two days. Record high morning lows are also anticipated in South and coastal Texas on Wednesday and Thursday.
While heat will gradually increase in the interior valleys of California later in the week, temperatures are expected to remain below record levels.
A broad mid to upper-level trough extending from eastern Canada through the Great Lakes, Ohio Valley, and Northeast will maintain below-average temperatures across large portions of the East during the middle to late week. Scattered afternoon showers are likely in the Lower Lake area into the Ohio Valley on Tuesday, followed by showers across the Central Appalachians into portions of the Mid-Atlantic on Wednesday.
