Areas affected...parts of eastern Kansas

Concerning...Severe Thunderstorm Watch 345...346...

Valid 120017Z - 120215Z

The severe weather threat for Severe Thunderstorm Watch 345, 346
continues.

SUMMARY...A corridor of significant damaging winds and hail remains
possible over parts of eastern Kansas. A tornado may also occur.
Localized gusts of 80-100 mph are possible. An additional watch may
also be needed into parts of southern Kansas.

DISCUSSION...Storms that crossed south out of Nebraska have merged
into a convective complex with periodic mesocyclones, now moving
into Riley and Pottawatomie Counties, and soon I-70. This complex
continues to have an impressive satellite presentation, and a very
moist and unstable air mass remains ahead of it. The system has been
moving south at close to 30 kt, with a small degree of backbuilding
toward the west. Recent radar trends also indicate a growing area of
severe outflow, and this may persist for several hours,
necessitating the need for another watch to the south.

Areas affected...southeastern Mississippi and southwestern AL

Concerning...Severe Thunderstorm Watch 320...

Valid 170418Z - 170545Z

The severe weather threat for Severe Thunderstorm Watch 320
continues.

SUMMARY...Isolated severe wind and hail will remain possible tonight
before storms move offshore.

DISCUSSION...Across southern MS/AL, the ongoing linear complex of
storms is expected to continue to track southward toward the coast
tonight. Some weakening has been noted, mainly on the eastern flank
where CAPE is lower. The upshear side of the thunderstorm complex is
expected to remain over land beyond 05z tonight, potentially
allowing for some additional weakening due to nocturnal
stabilization. However, moderate buoyancy and mid-level flow of
50-60 kt will remain supportive of stronger downdrafts capable of
damaging gusts as storms approach the coast tonight. It remains
unclear how much severe threat will remain beyond 05z, but at least
a few damaging gusts are possible.
