Squall line approaches

Thanks tor the storng overnight LLJ a squall line deelvoped to our west and has moved into areas to our north and west. A tornado has already touched in Madisonville,KY this morning. A extreme amount of shear exisits ahead of the squall line (helicity values over 700 m/s^2). This promotes the chance that any storm may turn tornadic. Strong gusty winds are the other main threat. Should a stronger storm track over Warren county some hail may occur. This squall line will redelevop and strengthen to our southeast as the last update indicated. Southeast KY and northern TN will have a very nasty day and the SPC has upgraded these regions to a moderate risk.
