Strong storms push through St. Louis area

The first round of storms brought strong winds, heavy rain, hail and a tornado warning. More storms are possible into the evening

ST. LOUIS — A line of severe storms is moving through the St. Louis area, bringing heavy rain, strong winds and several warnings and watches.

A tornado warning has expired for parts of Madison, Macoupin, Bond and Montgomery counties in Illinois. 5 On Your Side chief meteorologist Scott Connell said the tornado warning was prompted by radar-indicated circulation. There is no confirmation of a tornado on the ground. 

Some of the St. Louis area also is under a severe thunderstorm warning, including parts of the City of St. Louis, St. Louis County, Crawford, Gasconade, Phelps and Franklin.

5 On Your Side's Scott Connell is giving an update on Thursday's storms as they move through the area. You can watch his live updates in the YouTube video below or at the top of this page.

The main threat Thursday will likely be strong, gusty winds with an isolated tornado south and west of St. Louis.

If the complex of storms diminishes before it gets to the metro area, then the odds of late afternoon or evening severe weather are expected to be higher. The second wave of thunderstorms will likely produce strong winds, some hail and isolated tornadoes with the best chances appearing to be along and south of Interstate 70 during the late afternoon into the evening.

One thing is certain, once the rain comes to an end, much cooler weather returns to kick off what is considered the unofficial first weekend of summer. Temperatures for Memorial Day weekend will start out well below average and recover to near average by Monday. Early morning lows will be in the 40s for areas away from the metro both Saturday and Sunday morning.
