Issued at 1226 AM CDT Mon Sep 8 2025
Longwave troughing over the Great Lakes region is beginning to
lift away to the northeast. As it departs, a weak, residual upper
trough is expected to linger across the southeast US through the
week. By Friday and into the weekend, the trough begins to
amplify, digging further southeast as it moves into the western
Atlantic. The base of this trough may dig as far south as the
Florida Peninsula. At the surface, the frontal boundary that
pushed through the area yesterday has stalled over the central
Gulf. Much drier air has begun filtering into the area, allowing
for dewpoints this morning to crater into the low to mid 50s. This
push of drier air will be very brief, however, as high pressure
to our north anchors itself over the Appalachians and a weak low
pressure system tries to develop over the east central Gulf. These
features will allow for winds to become more easterly, helping to
advect moisture back into the area later today from east to west.
This could potentially lead to a few isolated showers and storms
along coastal counties this afternoon and again on Tuesday
afternoon.
By Wednesday, guidance continues to suggest that another cold air
damming event could set up across the southeast US as low pressure
systems attempt to develop along the stalled front off the US east
coast and the high lingers over the Appalachians. If it manages to
reach us, it probably will not result in much cooler temperatures,
but guidance does suggest that it could lead to drier conditions and
lower dewpoints for the remainder of the week and into the weekend.
Highs through the period will generally range from the mid 80s to
the low 90s and lows will range from the low to mid 60s inland to
the upper 60s to low 70s along the coast. A Low Risk of rip currents
today quickly increases to a High Risk on Tuesday and Wednesday. The
rip current risk subsides back to a Low risk by Thursday. /96
