The National Weather Service is calling for some severe weather this afternoon and evening around Evanston — including the possibility of “hail to the size of baseballs.”
The forecast also calls for damaging winds in excess of 75 miles per hour and a potential for strong tornadoes as well as very heavy rainfall that could cause flash flooding.
A very warm, humid and unstable air mass will blanket the area and a strong upper-level disturbance will move across the region this evening — creating favorable conditions for a severe weather outbreak.
Thunderstorms are forecast to produce one to three inches of rain, with very high rainfall rates in some of the stronger storms.
