Active pattern: Strong storms and much needed rain headed to Central Illinois
Key Takeaways
Strong to severe storms possible Tuesday evening
Damaging wind gusts the primary threat, brief tornado possible
Periods of rain showers through Wednesday morning
Additional rounds of rain Thursday through Friday
A few decaying showers and isolated non-severe storms will be possible throughout the day on Tuesday, mainly west of the Illinois River. Better chances for showers and storms will arrive Tuesday evening as a more organized line of storms heads our direction. The storms will likely be weakening as they move into the area after 7 pm but still may produce damaging wind gusts and perhaps an isolated tornado.
The Storm Prediction Center has placed some areas west of the Illinois River within a Level 2 Risk (Slight Risk) where the risk of severe weather is highest. The risk of severe weather should end by midnight though periods of rain and storms will continue overnight and through Wednesday morning as the front stalls. It looks like we'll become dry Wednesday afternoon and should remain dry through Wednesday night. Rainfall amounts through Wednesday will generally range from 1.00″ to 2.00″, though locally higher amounts over 3.00″ are possible west of the Illinois River.
Showers and storms will redevelop Thursday afternoon/evening and continue into Friday. As of now sever weather appears unlikely. These showers and storms should bring an additional 0.50″ to 1.00″ of rain to the area which will result in an area wide total of 1.00″ to 3.00″ with locally higher amounts up to 4.00″ possible west of the Illinois River.
The NWS office in Lincoln will be getting a software update that will take weather radios off air for portions of Central Illinois from 7 am on Tuesday, June 3rd through 4 pm on Thursday, June 5th.
The update is to the NWS AWIPS computer system, which they use to display and integrate weather and water information, and to send life-saving information, such as weather and water warnings, to the public. During this update, forecasts and warning information will come from their backup offices in Chicago and St. Louis.
The map below shows which counties will be left without weather radio coverage over the next few days. Counties with partial coverage may be able to pick up a signal from a neighboring radio tower, but the signal will likely be degraded and still may not alert when a warning is issued. There will be no service available in Peoria and Tazewell Counties.
We do have a conditional risk for severe storms on Tuesday evening so makes sure to download the CiProud 2 Go Weather App to receive weather information.

New Jersey Flash Flooding Sparks State of Emergency: What We Know
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. Flash flooding hit portions of New Jersey on Monday as Democratic Governor Phil Murphy issued a state of emergency, calling on residents to avoid unnecessary travel and to stay indoors. Newsweek reached out to the National Weather Service (NWS) via email for comment. Why It Matters The declaration marks a critical response to a pattern of increasingly frequent and severe weather events impacting the Northeast, including blistering heat waves. Murphy's decision to declare the state of emergency enables emergency agencies to deploy resources more rapidly and coordinate across jurisdictions. The declaration came after the NWS issued multiple flash flood warnings for areas across the state, highlighting the risks posed by sudden heavy rainfall. Regional emergency declarations are part of a broader trend across the United States this summer, as extreme weather events have produced catastrophic flooding in states including Texas and New Mexico. What To Know Newark Liberty International Airport (EWR) is under a ground stop until 10 p.m. ET due to the thunderstorms, the Federal Aviation Administration (FAA) said Monday. LaGuardia Airport (LGA) in New York is also under a ground stop due to the inclement weather. Both Essex and Union County in northern New Jersey are under a flash flood warning until 10 p.m. The NWS said on its website: "At 823 PM EDT, local law enforcement reported thunderstorms producing heavy rain across the warned area. Between 4.5 and 5.5 inches of rain have fallen. Additional rainfall amounts of 0.2 to 0.5 inches are possible in the warned area. Flash flooding is already occurring." The cities that could experience the flash flooding include: Newark, Elizabeth, Plainfield, Linden, Orange, Summit, Millburn, Caldwell, Clark, Fairfield, Union, East Orange, Irvington, West Orange, Montclair, Westfield, Livingston, Rahway, Maplewood and Scotch Plains. Burlington County in southern New Jersey is also under a flash flood warning until 11:45 p.m. ET, while Monmouth County and Middlesex County in central New Jersey are under a warning until 11:15 p.m. ET, the NWS says. Bergen County is under a flash flood warning until 9:45 p.m., as is Hudson County. Videos of the flooding in the Garden State have taken over social media as the weather event unfolds. This is a breaking news story. Updates to follow.
