Short term
An upper level ridge will try to build across the gulf of mexico
from the western atlantic today. Meanwhile, a weak shortwave will
track across east texas, arkansas and northern louisiana. This will
bring increased rain chances to at least the north an northwestern
portions of the forecast area. Maintained similar pops from the
previous forecast albeit a slightly higher end MAX in sw
mississippi. A rebound of daytime temps is expected as well with
highs back in the lower to mid 90s. The severe weather potential
appears to be conditional today. While the NAM version of meso
models indicate higher instability, capping in the lower levels
may limit convection. The GFS doesn't show much capping, but also
doesn't indicate nearly has conducive of an environment. Marginal
severe threat seems warranted with damaging winds the main threat.

The remainder of the week will be characterized by upper level ridge
building across the southern half of the country from texas to the
east coast. It will be a daily battle between daytime heating
induced convection and subsidence aloft. The ECMWF suggests the
downward motion will suppress most of the convection while the gfs
says the daytime heating will win out and scattered to numerous
storms will develop. Went in between those 2 with the pop forecast,
leaning towards the GFS for Friday as the ridge locally should begin
its weakening trend.

Long term
That weakening will continue into the weekend as a deep trough
tracks out of canada across the northeastern conus, eroding the
ridge across the southeastern us. This will allow strong daytime
heating to produce numerous afternoon thunderstorms. Expect this
summertime pattern to persist into at least the first half of next
week.

Aviation
GenerallyVFR conditions are expected for the forecast period.

Isolated summertime pulse storms are possible at several terminals,
and will show this with vcts in tempo groups.

Marine
Surface high pressure will move over the area and this will lead to
a break down of the winds over the coastal waters with winds mainly
controlled by diurnal fluctuations. Seas will also subside to 1-2ft
as well. Still looks like conditions begin to become more favorable
for nocturnal storms over the coastal waters mid and late next week
as at least one easterly wave moves through the gulf.
