.SHORT TERM...
(Today through Sunday night)
Issued at 311 AM CDT Fri May 24 2024

Expect a couple sprinkles or even an isolated shower with moist
onshore flow this morning. However it will not amount to much.
Were looking at another hot and humid day with highs in the
middle/upper 80s coast and lower 90s inland. Heat indices will
range from 98-103 degrees.

Expect very similar conditions as we move into the weekend with
highs in the upper 80s coast and lower/middle 90s inland. With
continued light to moderate onshore flow, heat indices will range
from 98-104 degrees.

.LONG TERM...
(Monday through Friday)
Issued at 311 AM CDT Fri May 24 2024

Next week will start off hot and humid, with high temperatures in
the mid-90s across the region. Central Louisiana and interior
southeast Texas could reach the upper 90s with highs around 97
degrees. This is mainly due to the high pressure that will extend
across the region from the east coast. This same ridge will also
cause our winds to be onshore, pushing high levels of low-level
moisture far inland. This ridge is strong for this time of year,
with our heights in the 97th percentile and 850 temperatures above
the 99th percentile. The apparent temperature will be greatest in
southeast Texas, with values rising above 105. The experimental heat
risk tool supports this by placing a swath of our area under a major
heat risk.

Temperatures will improve on Tuesday as a boundary moves across the
region. Models are showing a very diffuse and weak front that will
bring sporadic rainfall. For now, we only have PoPs around 20%.
Atmospheric dynamics still look marginal for this event so, as of
now,  we don`t expect to see widespread thunderstorms or severe
weather. Conditions could change and we could see PoPs increase or
even for thunderstorms to become widespread so make sure to keep an
eye on the forecast. With the passage of this system will come a
cooler and drier airmass, which will drop our temperatures back into
the upper 80s to the low 90s.

.AVIATION...
(06Z TAFS)
Issued at 311 AM CDT Fri May 24 2024

Some clouds are lingering overtop the area; the remnants of
convective blowoff. The expectation is for some low clouds to
continue developing with MVFR ceilings to prevail through the
early morning. Ground fog will develop at most terminals with VIS
to 5SM expected. After 15 or 16Z, the typical diurnal pattern
returns with breezy south winds and high cloud ceilings.

&&

.MARINE...
Issued at 311 AM CDT Fri May 24 2024

Moderate onshore flow is expected to prevail into the weekend as a
tightened pressure gradient between surface high pressure to the
east and a series of low pressure systems across the Plains
continues. Rain chances should remain low, although an isolated
light shower or two cannot be ruled out.
