We’re continuing a recent trend of forecasting in the western Great Lakes with a trip to the Quad Cities.

At 252PM, CT, Davenport was reporting a temperature of 71 degrees with a brisk south wind and clear skies, There appeared to be a vorticity maximum near St. Joseph, Missouri, and a whorl of clouds over the center of the United States was bringing a few of the clouds north to eastern Iowa, but the the real threat for deteriorating conditions is further to the southwest, where low pressure is going to continue developing over the next couple of days.
By tomorrow evening, areas near an emerging warm front will start to feature show rain and thunderstorms across southeastern Iowa. The center of low pressure will start to shift northeastward, and what had been convective in nature at the beginning of the day will become cooler and more stratiform rain showers, ultimately giving way to cool cloudy skies in the evening.
Tomorrow – Increasing clouds, late thunder possible, High 67, Low 47
Thursday – Rain with embedded thunderstorms. Ending late, then cooler, High 58, Low 43(Non standard)

This forecast was interrupted quite a few times while I tried to put it together. That vort max I mentioned at the beginning actually produced a couple severe storms east of Kansas City. Still not too bad in Davenport tonight, but it will deteriorate through the week. We’ll see at what pace.
