 Mesoscale Discussion 0444
NWS Storm Prediction Center Norman OK
1148 AM CDT Thu Apr 25 2019 Areas affected...southeast Louisiana into southern Mississippi and
southwest Alabama Concerning...Tornado Watch 102... Valid 251648Z - 251845Z The severe weather threat for Tornado Watch 102 continues. SUMMARY...The threat for locally damaging winds and brief tornadoes
continues within the watch area, and may increase this afternoon.
Severe storms may eventually spread into southwestern Alabama, and
this area will be monitored for watch potential. DISCUSSION...Outflow from a dying MCS currently extends from western
AL into southern MS, merging with the primary cold front into
south-central LA. Ahead of these boundaries, storms associated with
warm advection have periodically shown signs of being severe as they
moved across the New Orleans area, now over coastal MS. Sufficient
instability is in place over southwest AL and the western FL
Panhandle to support a severe storm or two, should they maintain
intensity. To the west, vigorous storms were ongoing along the cold front
extending from central-southern LA across the northern Gulf of
Mexico. Some air mass recover is expected over southeast LA ahead of
the frontal convection, and shear profiles will remain favorable for
supercells capable of damaging wind or tornadoes with 0-1 SRH
averaging 150-200 m2/s2. ..Jewell.. 04/25/2019 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...BMX...MOB...JAN...LIX...LCH...
