The chance for rain and thunderstorms will increase as early as mid-morning Memorial Day, with the potential for a few stronger thunderstorms Monday afternoon and evening.
A cold front passed through northern Illinois and southern Wisconsin late Saturday night bringing a few stronger thunderstorms south of the immediate Rockford area.
That front will lift back north as a warm front during the day Monday but may be tempered a little with showers and thunderstorms during the morning. Severe thunderstorms over the Plains Sunday will form into a complex of storms, shifting east Sunday night into Monday morning, and moving across the Stateline mid to late morning.
The first round of rain will move east early afternoon with possibly a second round of storms developing as the warm front lifts north into northern Illinois. It’s this second round of storms that could turn strong to severe with the potential for damaging winds, hail and even isolated tornadoes – especially along the warm front.
The storm threat will decrease Monday night into Tuesday but then pick back up Tuesday evening and night with thunderstorms and heavy rainfall going into Wednesday morning. If you’re planning on attending some of the Memorial Day parades that will be taking place Monday, be sure to keep an eye on the radar.
