The severe weather threat for Tornado Watch 38 continues.
SUMMARY...Overall severe threat across east-central AL appears to be
slowly diminishing. Downstream watch issuance into
west-central/southwestern GA appears unlikely this morning.
DISCUSSION...A small, low-topped cluster of storms is ongoing across
parts of east-central AL at 1515Z. Although strong flow aloft is
present over this region, instability remains rather weak owing to
persistent cloud cover and poor mid-level lapse rates. Better
forcing for ascent should gradually shift northward and away from
west-central/southwestern GA through the remainder of the morning
and continuing into the afternoon. This should lead to a gradually
diminishing trend to the ongoing convection. Regardless, an isolated
strong wind gust cannot be ruled out across a small part of
east-central AL in the short term (next hour or so). Given current
observational trends, downstream watch issuance into
west-central/southwestern GA will probably not be needed.
