.DISCUSSION...
(Today through Sunday)
Issued at 1204 AM CDT Mon Jun 1 2026

Current conditions still remain plenty warm and humid, with temps in
the mid to upper 70s and near matching dewpoints. At the surface,
the high pressure will maintain light southerly to near calm
flow. Tonight, we could see another round of patchy fog. While
dense fog is not expected, it is advised to commute with caution
late tonight into early tomorrow morning.

Other than being careful with the potential fog, it is definitely
advised to be cautious while outdoors today and tomorrow. Highs will
get into the upper 80s to mid 90s with dewpoints in the 70s. This
will yield heat indices in the 100s in some areas. While the
issuance of heat products will be unlikely, the probability of
feeling like a melted ice cream will be high if one decides to go
on a run these next few afternoons.

From the midweek period to the end of this forecast period, isolated
to numerous rain chances will prevail. Some of this activity is
expected to be seabreeze / diurnally driven, however it will have
some assistance first from a weak frontal boundary (Wed/Thu) then
from an upper low expected this weekend. The good news is that the
expected rain and cloud cover from mid week are likely to keep MaxTs
in check, although one will still be precipitating while participating
in outdoor activities.

.AVIATION...
(06Z TAFS)
Issued at 1204 AM CDT Mon Jun 1 2026

Winds speeds have become near calm tonight under mostly clear upper
decks. Thanks to the high moisture content, we could see some patchy
ground fog again tonight, however dense fog is not expected at this
time. Tomorrow afternoon, we could see some isolated to scattered
showers at or in the vicinity of the southern terminals.

.MARINE...
Issued at 1204 AM CDT Mon Jun 1 2026

Ridging will remain over Gulf waters to bring about light to
occasionally moderate onshore winds, low seas and nearshore
diurnal showers. Towards the midweek, upper low pressure will
place a weak boundary near the north Gulf coastline, increasing
rain chances and seas on increasing pressure gradient. Winds will
turn to the east and seas increase late in the work week in
response to this boundary and to high pressure developing over the
southeast US.

&&

.FIRE WEATHER...
Issued at 1204 AM CDT Mon Jun 1 2026

While there remains an anomalously moist airmass also set into
the north Gulf, dry conditions from high pressure are allowing
daytime RH values to mix down to the 45 to 60 percent range.

A slight weakness in the high pressure will develop, allowing for a
weak boundary to move into the region. This boundary will then
become the focus for more diurnally driven, seabreeze, rain chances
to return to the forecast.
