FAQ:

Does this impact warning services?

Our ability in the NWS to issue weather warnings will not be affected. Radar coverage remains strong across northern Illinois and far northwest Indiana due to available of surrounding radars. In addition, the Chicagoland area has two FAA Terminal Doppler Weather Radars at O'Hare and Midway Airports. It is our standard practice to utilize all of these radars as well as satellite data and high-resolution weather models during any thunderstorm event. We also rely on our vast network of trained spotters, important in any severe weather episode.

Does this change what I should do?

No. You still want to be aware of the forecast and the weather near you, especially if outdoor plans. If thunderstorms approach, move indoors quickly and be prepared to do so in advance. As always, have multiple ways to receive a weather warning and in the case one is issued for your area, move quickly into shelter.
