On the north side of this strong storm system, wintry precipitation continues to plague parts of the Upper Midwest, Great Lakes and New England. Winter alerts remain in effect for 9 million people, including in Green Bay, Wisconsin; Marquette, Michigan; Burlington, Vermont; and Portland, Maine.

A severe thunderstorm watch is in effect through late this evening as thunderstorms move across south-central and southeast Lower Michigan.

Southern Lower Michigan could see thunderstorms Sunday afternoon through evening. Risks include large hail, damaging winds, and isolated tornadoes, particularly in southwest Michigan Sunday evening. Southeast Michigan faces a slight risk of severe weather Sunday,

FIRST ALERT: Storms later tonight through Monday morning. Damaging winds are possible (midnight through 4 a.m.) and tornado risk. That line will move toward our region through the late evening and, if it holds together, could bring us a quick-moving shot of strong to severe storms right around midnight.

WLKY meteorologist Susanne Horgan has a look at our severe weather threat for late-day Sunday into Sunday night.

Three people were killed in Hidalgo County, where one city said there had been a “record-breaking downpour,” while another was killed in Mexico.

Drenching rains along the Texas-Mexico border trapped hundreds of people in flooded homes and in cars stranded in high waters, scrambling rescue crews to calls for help that continued Friday even as the downpours let up.
