AREAS AFFECTED...SOUTHEAST LOUISIANA...SOUTHERN MISSISSIPPI AND
ALABAMA
CONCERNING...SEVERE THUNDERSTORM WATCH 181...
VALID 292243Z - 300045Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 181
CONTINUES.
SUMMARY...DAMAGING WINDS REMAIN POSSIBLE AS AN MCS SLOWLY PUSHES
SOUTH ACROSS FAR SOUTHEAST LOUISIANA AND SOUTHERN MISSISSIPPI AND
ALABAMA. TRENDS ARE BEING MONITORED FOR THE NEED FOR A DOWNSTREAM
WATCH ISSUANCE ACROSS PARTS OF THE FLORIDA PANHANDLE.
DISCUSSION...A SQUALL LINE CONTINUES TO PUSH SOUTH/SOUTHEAST WITH A
FEW WIND DAMAGE REPORTS NOTED OVER THE PAST 1-2 HOURS. MORE
RECENTLY, OBSERVED WINDS HAVE LARGELY BEEN NEAR 35-40 MPH AND MRMS
ECHO TOPS SHOWS A SLIGHT WEAKENING TREND OVER THE PAST HALF HOUR.
ADDITIONALLY, ANVIL SHADING DOWNSTREAM OF THE MCS IS COOLING SURFACE
TEMPERATURES, RESULTING IN A GRADUAL DECREASE IN SURFACE-BASED AND
MIXED-LAYER CAPE IN RECENT MESOANALYSES.
DESPITE THIS WEAKENING TREND, A NARROW PLUME OF 1000-1500 J/KG
REMAINS IN PLACE IMMEDIATELY DOWNSTREAM OF THE MCS, SO SOME
RE-INTENSIFICATION APPEARS PLAUSIBLE OVER THE NEXT HOUR OR SO BEFORE
THE MCS REACHES THE COAST. CONSEQUENTLY, THE POTENTIAL FOR DAMAGING
WINDS (MOST LIKELY BETWEEN 40-60 MPH) WILL LIKELY PERSIST FOR THE
SHORT-TERM.
FURTHER EAST, THE PRIMARY BOWING SEGMENT OF THE MCS IS BEGINNING TO
APPROACH THE MOBILE, AL AREA. BASED ON RECENT STORM TRACKS, IS
APPEARS POSSIBLE THAT THIS SECTION OF THE LINE MOVES INTO THE FAR
WESTERN FL PANHANDLE WITHIN THE NEXT 1-2 HOURS. THIS MAY REQUIRE A
WATCH EXTENSION OR TARGETED WATCH ISSUANCE IF RE-INTENSIFICATION OF
THE MCS OCCURS.
