A few isolated showers/storms are possible late today-tonight as warm front lifts northward. These will move south-southwest to north-northeast over the area. A couple football games may be affected by these. The may still be an isolated shower/storm or two early Saturday morning.
Highs today will run in the 80s with around 70 for lows tonight as the high humidity surges in.
Meanwhile, the leftovers of storms in Iowa will pass morning to afternoon. These showers & storms should exit, bring a break, followed by the potential of a few more storms in the evening-night.
Highs Saturday will be in the muggy 80s with near 72 Saturday night for lows.
Sunday-Monday are looking drier & drier. Looks breezy, hot, humid & hazy with highs around 90 & lows in the lower 70s. heat indices will be near 100.
We still look warm upper ridge-dominated until late September. Above normal temperatures should dominate, unless a Pacific hurricane gets far enough north to put a kink in the upper jet through the Northern Hemisphere. This could change this pattern dramatically.
Above normal temperatures...........
Then a sharp cool-down in late September.........with below normal temperatures.
With upper ridge domination, total rainfall is forecast to run 1.30-2" now-September 23. This is below normal.
Major, flooding rainfall will occur on edge of ridge from Kansas through Nebraska, Iowa, Minnesota, Wisconsin & northwestern Illinois.
Heavy rainfall may also occur along the Gulf Coast as the Atlantic & Caribbean see increased potential of tropical activity.
