The Springfield area remains in a "slight risk" category for severe weather potential Monday evening, according to the National Weather Service in Lincoln.

The most significant threat said Darrin Hansing, a service hydrologist for the NWS, is straight line winds that could top out at 70 MPH.

Hansing said there is a 70% of showers and thunderstorms moving through the Springfield area, probably around 6 to 7 p.m.

Straight line winds are thunderstorm winds that have no rotation and can damage tree branches and power lines.

There is also the potential for hail and frequent lightning, Hansing said, though no tornado threats.

Monday's high temperature was predicted to be 90 degrees, with a "feel like" temperature of near 100 degrees.

A severe thunderstorm warning has been issued for southern Menard County, northwestern Sangamon County, southeastern Cass County and northeastern Morgan County until 7 p.m.

Severe weather is more likely north of a line extending from Havana to Danville, he added, with the Chicagoland area bulls-eyed as far as the greatest risk for severe weather Monday.

Scattered showers and thunderstorms should be largely out of the Springfield area by 5 or 6 a.m. Tuesday, Hansing said.

This story will be updated.
