Thunderstorms will develop late this afternoon or early this evening from the southwest and will affect the entire area overnight.
Another round of thunderstorms is expected to develop later today and spread across the region tonight. Some of these storms may be capable of producing hail up to quarter size and heavy downpours.
Late Thursday (4/9) afternoon into the evening the threat exists for an outbreak of severe weather thunderstorms including the potential for tornadoes. All of the ingredients need to come together just right for a significant severe weather outbreak and if even just one ingredient fails to materialize, the threat decreases substantially. Early indications are that many of the ingredients for a significant outbreak of severe thunderstorms could be in place Thursday and later forecasts and outlooks should be closely monitored.
Niles Residents: If heavy rainfall does occur, please remember to move cars to high ground and remove valuables from basements. If you have an emergency and need immediate help please dial 911.
