Closest strike: 25.54 miles Monitor Storms You are not at immediate risk, but frequently check WeatherBug to see if storms are moving towards you. Be aware that new storms can also form with little notice.

There is a Marginal 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 AN ENHANCED RISK OF SEVERE THUNDERSTORMS FOR PORTIONS OF THE UPPER MIDWEST INTO THE GREAT LAKES THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE NORTHEAST...CENTRAL HIGH PLAINS...AND GULF COAST STATES SUMMARY Multiple rounds of severe thunderstorms are still expected across the Upper Midwest and Upper Great Lakes into tonight. A couple of tornadoes are possible but damaging wind gusts are expected to be the more widespread hazard, in addition to isolated large to very large hail. Severe storms also remain a concern across parts of the central High Plains, Northeast, and Southeast/Tennessee Valley. 20Z Update The main change made to this outlook was to expand the wind-driven severe probabilities southward across portions of the Upper Midwest based on observational trends. A belt of relatively thick cloud cover exists across portions of the Midwest. However, considerable clearing and a CU field, along with isolated thunderstorms, has developed across eastern IA into southern WI, where appreciable buoyancy (2000-3000 J/kg MLCAPE) and up to 40 kts of effective bulk shear reside. Furthermore, a few of the latest WoFS runs also depict some higher thunderstorm coverage across eastern IA into southern WI. As such, the thinking is that organized severe potential, mainly in the form of severe gusts, should exist across this region through the evening. Otherwise, the previous forecast remains on track, with relatively minor changes made to the thunder and severe probabilities to reflect the latest observations and guidance consensus.
