Severe Storms Possible Mississippi / Tennessee Valley Region Today...

The same storm system responsible for severe weather across the Southern Plains yesterday is moving slowly East and will bring a threat of active weather across portions of the Mississippi and Tennessee Valley regions today.

Above is the latest severe weather outlook for today from the Storm Prediction Center (SPC) in Norman, OK.  Severe storms are forecast within the yellow shaded areas, with large hail and damaging wind gusts the primary threats.  Isolated tornadoes cannot be ruled out from any particularly organized storm that is able to remain isolated from the larger overall precipitation area.

The cool front of Pacific origin that moved across the Southern Plains yesterday is approaching the Western edge of the severe weather outlook area this morning.  This and other boundaries left over from thunderstorm activity of yesterday will serve to focus for new development and/or reorganization of the existing activity later in the day.

Along the Mid-Atlantic Coast and adjacent portions of inland North Carolina and Virginia, a few strong to severe storms can be expected in the afternoon heating today.  Damaging wind gusts and some hail are the primary threats.

Storms may also approach severe limits, mainly with respect to hail, during the peak heating this afternoon across portions of Oklahoma and along the Kansas/Oklahoma border region (as indicated in brown on the above image).  Thunderstorms will pop-up during the heat of the day beneath a cold pocket of air aloft.  This may allow some of the storms to produce hail near severe limits and/or gusty winds before sunset.

Folks living across the severe weather threat areas should remain alert today.  Listen for later statements and possible warnings, and be sure that you've identified the safest place to go for shelter in the event that severe weather threatens your area.
