An active summertime weather pattern will maintain daily threats of scattered severe weather and flash flooding across parts of the Central and South-Central U.S. through mid to late week. A few slower-moving disturbances and frontal boundaries will interact with an abundance of Gulf moisture and instability, setting the stage for several organized clusters of thunderstorms the next few days. The strongest severe storms will have the potential to produce damaging winds, large hail, and a few tornadoes from the High Plains into the Ozarks. In addition to the severe weather, intense rainfall rates in these storms could yield scattered instances of flash flooding over much of the same area. West of the Rockies, afternoon thunderstorms capable of damaging wind gusts and isolated excessive rainfall are expected over the Great Basin owing to an influx of moisture on the periphery of a broad upper-level ridge. Through Friday, much of the Northern Plains and Great Lakes can enjoy unseasonably cool weather with the arrival of mild Canadian air behind a Northern Tier cold front. In contrast, parts of the West, Southern Plains, and Florida will continue to bake under intense heat the next two days. High temperatures across these heat-stricken regions will run from the 90's into the triple digits, prompting numerous Heat Advisories and Extreme Heat Warnings through today and Thursday. Thunderstorms could provide some relief from the heat in the West, although by Friday much cooler weather will begin to overtake the region as a large closed low and associated frontal system arrive from the Eastern Pacific. The warmth, dry fuels, and gusty winds will also maintain elevated fire weather conditions across parts of the Great Basin and Four Corners through tomorrow.
