More storms

Here's the latest weather map:


You can click on it for a larger view.

The warm front has passed to our north now, but the cold front is still to our west.  This puts us in the zone called the "warm sector" of the system...where warm southerly winds carry heat and moisture into our area.  This, combined with ample sunshine out there this morning and a good upper level jet flow is creating a very ripe atmosphere for thunderstorms to blow up.  In fact, storms are already going now across middle Tennessee and are moving northeast into southern Kentucky this morning.

As the day wears on, I expect thunderstorms to continue to blow up along the I 65 corridor of Kentucky and intensify into possible supercells and small line segments.  These storms will drift northeastward into the Bluegrass counties of Kentucky later this afternoon.  VERY heavy rainfall, flash flooding, and high winds with downbursts will be the threats from these storms.  Intense lightning will be a good bet too I think because of all the water vapor in our airmass.

Stay alert today, especially if you're going to be outside as these storms could blow in very quickly.  Tomorrow, the cold front on the above map will blow into Kentucky, and more severe weather will be possible along the front.
