Severe Weather In Deep South Today

The above image shows the latest severe weather outlook for today and tonight, from the SPC.  Severe thunderstorms are forecast within the green outlined region.  The highest threat of severe storms, including tornadoes, will fall within the area outlined in red (and with the light blue hatch marks) in the "probability" image below:

A stationary front stretches across the region early this morning, and is expected to move little today (see latest HPC surface weather map and forecast image below):

Thunderstorms have already developed early this morning along and North of the boundary across portions of northern and eastern Arkansas, western Tennessee and adjacent portions of Mississippi and Alabama. 

Marginally severe hail is possible with some of the stronger storms this morning.  The main threat will come this afternoon and evening as the atmosphere along and South of the boundary heats and destabilizes.  Large hail, damaging winds and isolated tornadoes will be possible with this activity.
