   Areas affected...Parts of northern Mississippi

   Concerning...Tornado Watch 303...

   Valid 202238Z - 210015Z

   The severe weather threat for Tornado Watch 303 continues.

   SUMMARY...Several ongoing severe storms are moving into an
   increasingly favorable environment for tornadoes across northern
   Mississippi.

   DISCUSSION...A couple semi-discrete supercells are tracking eastward
   across parts of northwest/west-central MS. Ahead of these storms, a
   35-kt low-level jet (sampled by area VWPs) is contributing to ample
   low-level clockwise hodograph curvature with around 200 m2/s2
   effective SRH. Given warm/moist surface-based inflow and this
   enhanced streamwise vorticity, the ongoing storms may intensify as
   they continue eastward -- with an increasing tornado risk. Large
   hail and locally damaging winds will also be a concern.
