Another strong storm will come out of the southern Rockies and push toward the Great Lakes by Wednesday.  This is a classic severe storm set-up, but the likely timing of the system currently puts us into the very low side of severe storm possibilities.  The highest risk areas will be west of us tomorrow afternoon/evening and east of us for Wednesday afternoon.

The past two similar systems were moisture-shy.  In both cases, nothing of consequence happened locally – thanks to that lack of moisture.  This time, however, there will be plenty of moisture in the equation.  So severe storm outbreaks appear likely tomorrow and Wednesday, but, as mentioned above, the main part of the storm system will reach us during the lull between the two outbreaks.

Here’s how it’s shaping up…a warm front will push through the lower Ohio Valley tonight and tomorrow morning.  This will bring high moisture content into the area.  The front should generate a few hours of showers (and possible thunderstorms) tomorrow morning between about 7 A.M. through Noon.  Any thunderstorms that form tomorrow morning could produce small hail. Then, we’ll see a windy and warm afternoon with temperatures nearing 70 degrees.

During tomorrow afternoon/evening thunderstorms will develop along a cold front from Arkansas to Missouri into Illinois.  A widespread outbreak of severe weather is expected.  As the night continues this cluster of severe weather will drift eastward and weaken.  It is expected to drift through the I-65 corridor Wednesday morning remaining in the weakened state.  Then, Wednesday afternoon it is expected to re-intensify into another area of strong to severe storms as it moves east of the I-75 corridor.

Even though the severe threat looks quite low for the Louisville area, the two (or more) rain systems we expect could easily drop !” to 1.5″ of rain by midday Wednesday.
