Continue reading for today's outlook from the National Weather Service's Storm Prediction Center. -------------------- National Severe Storm Outlook THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE UPPER GREAT LAKES INTO THE LOWER MISSOURI VALLEY SUMMARY Severe thunderstorms capable of producing damaging wind gusts, severe hail, and a couple of tornadoes will continue across portions of the Upper Great Lakes and Lower Missouri Valley through late tonight. 01Z Update Water-vapor imagery and VWP data indicate a robust midlevel wave and accompanying belt of 50-60-kt west-northwesterly flow overspreading the Upper Midwest, and this feature will continue east-southeastward across the Great Lakes region tonight. In the low-levels, an attendant cold front will continue east-southeastward across this region as well. In the Upper Great Lakes and Midwest, 50-60 kt of deep-layer shear (sampled by regional VWPs) oriented perpendicular to the cold front and a relatively narrow corridor of strong pre-frontal buoyancy (around 3000 J/kg MLCAPE) will continue to promote semi-discrete supercell structures. Locally damaging wind gusts, severe hail, and a couple of tornadoes will be possible with this activity, given ample low-level hodograph curvature (around 250 m2/s2 effective SRH) beneath the core of a 40-kt LLJ. This activity will generally spread east-southeastward across parts of Lower MI tonight, where a continued risk of damaging wind gusts, severe hail, and a tornado or two will continue ahead of the cold front before encountering increasingly stable air. Farther south, a couple organized clusters are tracking southward across parts of southern IA and western IL. Given strong cold pools with this activity, the primary concern will be severe wind gusts and isolated/sporadic hail. These storms will continue tracking south-southeastward along a surface-based buoyancy gradient before gradually weakening overnight.
