Live Weather Radar: Track Severe Storms in Real Time as They Approach Your Area

Updated Midwest Weather Radar Shows Life-Threatening Storm Line Racing East Tonight The latest Doppler weather radar loops reveal a rapidly intensifying squall line stretching from eastern Iowa through southern Wisconsin and into northern Illinois, moving toward Michigan and Indiana this evening. Embedded supercells on radar are already producing hail up to 2 inches, 75 mph straight-line winds, and several tornado signatures, matching the “Enhanced Risk” issued by the Storm Prediction Center for June 11 – 12. Key radar highlights as of 7 p.m. CDT • Quad-City live weather radar shows a bow echo racing east at 60 mph—classic derecho formation. • Chicago’s interactive storm radar indicates discrete cells ahead of the main line, raising a strong tornado threat for the western suburbs between 8 p.m. and 11 p.m. • Detroit Doppler radar is still quiet, but high-resolution future-radar models bring the line across Lake Michigan after midnight, coinciding with a heat-index-driven unstable airmass already in place. Why today’s weather radar matters 1. Real-time warning window: Storm-relative velocity scans are the first to show rotating updrafts minutes before a tornado warning is issued. 2. Giant-hail detection: Dual-pol radar products are flagging 2–2.25 inch stones west of Rockford; keep vehicles sheltered. 3. Power-outage planning: The leading edge of the bow echo has a history of 70+ mph winds—outage probability exceeds 50 % along I-94 tonight. How to track the outbreak • Bookmark “Midwest Live Weather Radar” in your browser for constantly updating composite reflectivity. • Mobile: Open the NWS Radar Mosaic or any app offering level-3 NEXRAD data; enable lightning and storm-track layers. • Smart TV: Search “live storm radar stream” on YouTube for continuous Doppler coverage from local TV meteorologists. Safety checklist before the line reaches your county • Enable Wireless Emergency Alerts and NOAA Weather Radio SAME codes. • Secure patio furniture; wind loading increases in straight-line gust fronts. • Charge phones and portable power banks; widespread outages are likely with a fast-moving derecho scenario. Looking ahead on the radar High-resolution convection-allowing models keep the MCS intact across lower Michigan and northern Ohio through sunrise, with a secondary flare-up Friday afternoon along the warm front pushing into western Pennsylvania. Keep monitoring weather radar loops, especially the 1-km reflectivity updates every two minutes, for any new rotating storms that develop ahead of the main cold front overnight.
