A flash flood warning was in effect in the Lawrence area until 7:45 a.m. but was to continue until 9:30 a.m. in Leavenworth and Wyandotte counties, she said. However, by 7 a.m., most of the severe weather had moved on through the area and into Missouri, she said.

“We’re left with a cloudy morning in our region,” Schack said.

Temperatures this morning were in the upper 60s.

Today ‘s high will be 79, which is well below average, with northwest winds 10 mph. Clouds will decrease in the afternoon, Schack said.

She predicted that the relatively cool temperatures will continue overnight. The low is expected to fall to 57, which would match the record low for Wednesday’s date, she said.

Wednesday’s high will climb to 83 under mostly sunny skies.

There is a possibility for some isolated thundershowers on Wednesday night and Thursday morning, she said. The National Weather Service puts the chance at 20 percent.
