An upper-level low lifting in from the south will bring a bit more active weather to the Stateline, helping bring scattered shower and thunderstorm chances as we begin the new work week. With plenty of moisture in place, some of these storms could produce heavy rain, though severe weather will not be on the table. Despite the clouds and occasional rain, temperatures will still climb into the low 80s.
Looking ahead, we'll begin to see a low-end severe weather threat develop Tuesday. Storm Chances will be isolated, but for some, may present the potential for damaging winds and large hail. Areas south and west of Freeport and Rochelle have been placed under a level 1 of 5 Marginal Risk. The strongest potential Tuesday will actually be up in the Upper Great Plains, focused in North and South Dakota.
The severe potential ramps up noticeably as we head into the middle of the work week. A surface low lifting into Minnesota will drag a cold front closer to the region, setting the stage for storms to develop along that boundary. These storms are expected to push east into the Stateline Wednesday evening into Wednesday night, posing a risk for all severe hazards including damaging winds and isolated tornadoes. For now, the Storm Prediction Center has much of northwest Illinois and southern Wisconsin under a level 3 of 5 enhanced risk for severe weather.
Active Stretch Continues:
Please make sure to keep an eye on the forecast for not only Wednesday, but also Thursday as the surface low will likely contribute to potentially another round of significant severe weather.In their latest round of severe outlooks, the Storm Prediction Center has put the region under a 30% risk, which is equivalent to a level 3 of 5 enhanced risk.
Like Wednesday, a very moist and unstable airmass will allow all severe weather hazards to be on the table. So again, today, tomorrow, and even Wednesday morning will be a good opportunity to review your severe weather safety plan and make sure you are prepared ahead of time. With the potential for strong to severe storms increasing by midweek, having multiple ways to receive warnings and knowing where you would go pending severe weather makes all the difference.
