Lake Breeze Front Rapidly Retreating Back North As South/Southeast Wind Commences

It is truly amazing how much Lake Michigan can affect the weather in our region.  This time of year, especially after a cold spring, cold air can surge inland very quickly if the winds lighten on a very warm day.

As the winds lighten & the warm air rises, that cold, heavy, dense air over that icy cold water rushed inland to fill the void.  It can make it as far south as Lafayette, Attica, sometimes I-74 (although much more diffuse).  Such was the occurrence yesterday evening & last night.

Notice the overnight low temperatures!  Also, notice how the front is in retreat now.  It is 75 at Rochester, 74 at Kokomo, 67 at Crawfordsville, but still just 49 at Morocco.

We will see a skyrocket to the 70s by afternoon for the viewing area & some places are already there (80-82 possible in those places).  HRRR hi-res model brings 70s into Morocco by 3:30 p.m.

Some showers/t’showers continue to lift northwestward through the viewing area.  This afternoon, with much warmer weather & some areas of sun, some scattered t’storms may develop.  Again, like yesterday, an isolated severe t’storm is possible.  Where the sun is appearing south of I-74 & in northeast Indiana, surface CAPE (instability) is already at 500 J/kg.
