Intense upper level low now over Ontario, Canada is quickly moving east with associated trough. Jet max with core winds at 90 to 100 knots within this trough now over MN will lift northeast. With intense system aloft surface cyclone will remain very deep at 988mb. Cold front trails southwestard and connects up with another low over KS, OK, TX panhandle area. 850 mb jet will be nosing into MO, and IL around 14z bringing along very moist and warm air mass. 850 jet is forecast to strenghtin to around 50 knots and with 500mb speeds approaching 40 to 45 knots shear will insane. Main forcing will be cold front later, but with likely convergence and complex surface features a few cells will go up ahead and quickly develop rotation.
I will be targeting the IL MO area later today.
Below is an image of the RUC 500mb forecast!
