MD 0356 CONCERNING TORNADO WATCH 76…77… FOR PARTS OF SOUTHWESTERN THROUGH NORTHEASTERN LOUISIANA INTO NORTHWESTERN MISSISSIPPI
Mesoscale Discussion 0356
NWS Storm Prediction Center Norman OK
1247 PM CDT Wed Mar 30 2022
Areas affected...Parts of southwestern through northeastern
Louisiana into northwestern Mississippi
Concerning...Tornado Watch 76...77...
Valid 301747Z - 301845Z
The severe weather threat for Tornado Watch 76, 77 continues.
SUMMARY...Severe thunderstorms posing increasing risk to produce
tornadoes and/or strong, damaging wind gusts through 2-4 PM CDT.
This may including increasing potential for a strong tornado or two
by late afternoon.
DISCUSSION...Surface dew point increases through the mid 60s has now
contributed to moderate mixed-layer CAPE of 1500+ J/kg along a
narrow corridor of stronger 2 hourly (as of 17Z) surface pressure
falls, from near Fort Polk LA into the Greenville MS area.
Southerly flow around the 850 mb layer is forecast to continue to
increase up to around 70 kt along and east of the this axis through
19-21Z, contributing to further enlargement of already sizable
clockwise curved low-level hodographs. With this coinciding with
the sustained strong, and gradually intensifying, thunderstorm
development, supercell structures with strong low-level mesocyclones
will continue to evolve and pose increasing risk for tornadoes
and/or localized strong damaging wind gusts.
