If there is one thing that the Midwest has in spades, it’s towns called “Bloomington”
At 1153PM, ET, Bloomington was reporting a temperature of 52 degrees with clear skies. The still warm temperature at this late hour reflects Bloomington’s position within the warm sector of the pertinent upper level ridge. A weak trough at the upper levels is creating enough instability to develop a closed low over the Lower Mississippi Valley. This duality has given the impression that the two features are connected, but through the day tomorrow, they will pull apart, right over Indiana. The NAM suggests they will completely dissociate tomorrow, however the GFS foresees some rain through much of the day in Bloomington.
The dual systems will continue to the east with a good degree of speed, thanks to the short wave nature of the upper level flow. The shower activity will be out of the area by the time midnight comes and Wednesday arrives. There will be another feature organizing in the High Plains, encouraging warm air to remain in the Midwest. Despite the passage of a cool front on Tuesday, don’t expect Wednesday to be significantly colder in Bloomington.

We caught Bloomington at a good time. That system later in the week could be a doozy. Look at the current satellite though. Look at that wall of clouds right through the center of the country. Weather is fun.
