Dangerous Heat and Heavy Rainfall into the Weekend

Hot temperatures and high humidity are forecast to continue across the mid-Mississippi Valley into this weekend. Heat Advisories remain in effect. Heavy to excessive rainfall occurring at times through the weekend could bring areas of flooding to parts of the northern Rockies, upper Midwest, central Great Lakes, and southern New England.

Additional rounds of moderate to heavy rainfall occur this afternoon into tonight. While widespread heavy rain is expected towards east-central Iowa and far southern Wisconsin, confidence in the extent and impacts of the rain begins to decrease as one travels further north and west. However, there have been some trends in the forecast that would support renewed thunderstorm development as far north as I-90 later this afternoon, which is farther north that earlier forecast. Rainfall amounts with these northern storms could still easily reach 2-3 inches, but these higher rainfall totals will be more scattered in nature. Bottom line, much of the area is saturated and additional rainfall, even a small amount, can lead to renewed flooding concerns. Stay weather aware this afternoon into tonight!
After our widespread rain showers depart later this afternoon and tonight, look for drier and cooler weather for the bulk of next week. Some light showers move through Monday into Monday night, but impacts look to be light.
A number of roadways remain closed or flooded owing to heavy rain last night. If you encounter these roads, please find a different route!
