The National Weather Service reported that heavy rain and flash flooding threats continues along the Gulf Coast and across portions of the Mississippi Valley, Great Lakes and Ohio Valley.
"Monsoonal storms and the potential for flooding to continue for portions of the Southwest into the Great Basin and Rockies," states The National Weather Service. "Above-normal temperatures are expected from the northern Intermountain West into the northern and central Plains, while much of the East begins to cool down through late in the week."
According to The National Weather Service, daily shower and thunderstorm activity is expected across the Southwest and into portions of the Great Basin and Rockies. There is also a higher chance of localized flooding and "above normal daily temperatures are forecast to continue throughout the northern Intermountain West and Northern Rockies, while the heat also builds east out across the northern and central Plains through Friday (August 12th)."
Additionally, according to the weather service, a "quasi-stationary front from the Mid-Atlantic and draped through the Tennessee Valley and northern Gulf states/Lower Mississippi Valley will act as a focus for multiple rounds of showers and thunderstorms." The front will go slowly south with moist air ahead of the front supporting showers and thunderstorms which may result in heavy rainfall.
Another cold front is then expected to sweep through the region by late in the week, which is expected to bring in cooler and drier air, making temperatures dip to near or below seasonal average across the Eastern U.S. by the weekend. According to The National Weather Service, "the first frontal boundary will slowly weaken as it stalls over the Gulf states; with ample moisture and weak winds expected, slow-moving storms will be capable of producing heavy rain. There is potential for localized excessive rainfall and flooding."
