There is a Slight Severe Storm Risk for your location. Continue reading for today's outlook from the National Weather Service's Storm Prediction Center. -------------------- National Severe Storm Outlook THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS SOUTH-CENTRAL PORTIONS OF ILLINOIS AND INDIANA THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ALONG THE NORTHERN GULF COAST SUMMARY A corridor of tornado, damaging hail and wind threat persists from south-central Illinois into Indiana this evening. A broader zone of severe hail and wind extends from southeast Kansas into western Ohio. IL...IN...MO...OH The greatest tornado threat corridor extends from south-central IL into parts of central/southwest IN this evening, where air mass recovery continues out of the southwest. Supercells in this region have been tornadic at times, also producing large damaging hail. Given the extreme shear downstream, and continued low-level theta-advection, the environment remains conditionally favorable for a couple strong tornadoes through this evening over a small portion of IL and IN. The threat may extend as far east as western/central OH later tonight, with tornado potential depending on instability. For more information see mesoscale discussion 1171. Northern Gulf Coast A moist and unstable environment exists across LA and into southern MS/AL ahead of Arthur. Low-level shear may increase further this evening, with periodic mini-supercell potential and tornado risk. For more information see mesoscale discussion 1172.
