valid 211200z - 221200z
...no severe thunderstorm areas forecast...
...summary...
isolated thunderstorm are possible wednesday and wednesday night
across portions of southeast texas and louisiana.
...synopsis...
broad upper troughing will envelop much of the conus on wednesday.
an upper shortwave trough embedded within the large-scale trough
will pivot east across the south-central to southeast states on
wednesday into early thursday. as this occurs, some minor modified
gulf moisture will impinge on southeast tx into la/ms ahead of a
southward sagging cold front. this will support minor
destabilization (mucape around 100-300 j/kg) from southeast tx into
la. cool temperatures aloft and modest large-scale ascent may be
sufficient for isolated weak thunderstorm activity late wednesday
afternoon into the nighttime hours. severe storms are not expected.
