Short term (today through Tuesday)
A typical summertime surface high ridge, extending west from the
western atlantic (off the mid to lower atlantic u.S. Coast) to
the northeast gulf coast region, will remain in about the same
general orientation through early in the week. The daily changes
in the forecast will be mainly due to shortwave features in the
mid to upper levels moving across the southern plains into the
lower mississippi valley. A shortwave trough will move near the
texas louisiana border late today, so most of the focus and
support for convection today will be diurnal heating and the lake
and sea breeze boundaries. Instability over the more inland areas
may be sufficient for a few storms to pulse up to strong to
briefly near severe limits with the main threat being damaging
winds. Have continued near normal chances of mainly afternoon
showers and thunderstorms today (30 to 40%) and very warm high
temperatures mostly in the lower 90s, except for upper 80s near
the immediate coast. A few showers and thunderstorms may linger
into the evening hours, mainly well inland from the coast,
otherwise most of tonight should be dry in most locations with
warm lows in the 70s.

A higher amplitude shortwave trough will approach the central
gulf coast region from the southern plains and ARKLATEX region on
Monday. Precipitable water in most areas should rise to near 2
inches or slightly higher in the afternoon, so have maintained the
higher likely chances for showers and thunderstorms from inland
south mississippi into inland southeast louisiana where a
convective complex could move through the region. Some stronger
storms with gusty winds and heavy downpours are likely. The
stronger shortwave trough should move through early Tuesday,
however additional minor shortwaves may move through in west-
northwest flow and interact with deep layer moisture profiles that
should be similar to Monday. Another convective complex may move
through the region, and showers and thunderstorms should be
numerous over most land areas with scattered showers and
thunderstorms expected offshore. Gusty winds and heavy downpours
will again be possible on Tuesday. Temperatures should be at least
a degree or two cooler for the highs on Monday and Tuesday with
the increase in convection.

Long term (Wednesday through Saturday)
A series of low amplitude shortwave troughs will likely continue
to move west to east, or west-northwest to east-southeast across
the southern states Wednesday into Thursday with the southern
extent of some convective complexes possible moving through at
least the northern portion of the forecast area. Have continued
elevated rain chances during the period, and some stronger storms
with gusty winds may occur due to the stronger westerly winds in
the mid levels. A subtropical ridge should then expand out of the
tropical atlantic into the gulf of mexico and central to eastern
gulf coast Friday and Saturday, so a drier and warmer pattern is
likely to return. 22 td

Aviation
Vfr conditions will prevail through most of the period for all
terminals. Light south winds expected expect higher in and around
any isolated storms this afternoon and evening. Prob30 for all
terminals in the afternoon and evening hours as isolated
summertime type convection is possible this afternoon and early
evening.

Marine
Southerly flow will continue through the entire forecast period as
surface high pressure sits of the atlantic southeastern coast.

Showers and thunderstorms expected to increase in coverage on Monday
and Tuesday while synoptic winds will decrease. Southerly winds
expected to increase late week as gradient tightens and surface high
builds westward into the northeastern gulf. Chances of showers and
storms will decrease by the end of the week.

Decision support
Dss code: blue.

Deployed: none.

Activation: none.

Activities: marginal risk of severe thunderstorms today.

Flood warnings continue along the mississippi and

visibility event; marginal risk severe or excessive rain.

Yellow = heightened impacts with short-fused watch, warning or
advisory issuances; radar support for slight risk severe or
excessive rain.

Orange = high impacts; enhanced risk severe; nearby tropical
events; hazmat or other large episodes.

Red = full engagement for moderate to high risk of severe and or
excessive rain; direct tropical threats; events of national
significance.
