Hotter-than-normal weather has prevailed for the past few days. The heat peaked in the Los Angeles area Wednesday with widespread 90-degree temperatures, around 15 degrees above normal.
The offshore flow creating this heat will turn around quickly to onshore Thursday, then become increasingly strong through the weekend.
High temperatures Thursday will drop a 10 degrees from Wednesday's highs.
The coolest weather will be over the weekend, however. Morning marine clouds will extend far inland each morning before clearing to sunshine.
High temperatures will drop below normal with low to mid-70s for coastal cities and middle to upper 70s in the valleys.
Rising temperatures and humidity across the mid-Atlantic will have it feeling like the end of June.
Slow-moving showers and storms will bring heavy rain and flooding potential.
Heavy rain returning to the northern Plains will generate a renewed flood threat for the Red River.
More than 20 tornadoes were reported by the National Weather Service with hundreds of hail and wind reports Sunday afternoon through Sunday night.
Several tornadoes touched down from Oklahoma to Iowa, including near Wichita, Kan., and Oklahoma City, on Sunday.
Severe storms may erupt from Oklahoma to Wisconsin on Monday as the storm system that spawned several tornadoes across the Plains on Saturday and Sunday shifts slowly to the east.
