.DISCUSSION...
Issued at 1037 PM CDT Mon Jun 8 2026

Tranquil conditions are expected for the rest of tonight with
clear to partly cloudy skies and light southeasterly winds. The
low temperatures overnight into early Tuesday morning will be in
the lower to mid 70s for most inland areas and the upper 70s to
lower 80s for the Houston Metro area and coastal locations.

There will be two features that will allow us to remain closer to
drier conditions rather than the active weather pattern we had
experienced last week. The first one is a board mid-level high
pressure meandering over Texas and Louisiana. The second one is
an upper-level high pressure anchored over the Mexico region. Both
of these will help limit rain development through at least the
end of the work week. Now, we will still have sufficient moisture,
diurnal heating, and instability for a few showers and
thunderstorms to be able to develop, particularly along and near
the seabreeze during the afternoon to early evening hours. We
might also see some streamer showers move into our coastal
locations in the mornings.

And...It`s summer in Houston! So we will likely see the typical
pattern of hot days and warm nights. Look for highs peaking in the
lower 90s for most inland portions and the upper 80s to lower 90s
along the coasts and lows in the mid to upper 70s inland and
upper 70s to lower 80s along the coasts. We will have increased
heat risk this week as heat indices peak in the lower 100s for
most of Southeast Texas through the upcoming weekend. Continue to
practice heat safety to protect yourself, loved ones, and pets
from the heat. If you plan to spend time or work outdoors, make
sure to take breaks from the heat/sun often, drink plenty of
water, and wear appropriate clothing. Never leave children,
vulnerable adults, or pets unattended in a vehicle.

.AVIATION...
(00Z TAF Issuance)
Issued at 532 PM CDT Mon Jun 8 2026

Sparse showers will taper off this evening with winds becoming
light and variable overnight. MVFR CIGS/Decks fill in again
overnight into the early morning hours of Tuesday. Could see some
isolated, brief instances of IFR CIGs during this early morning
period as well. Otherwise FLs will return to VFR levels by Tuesday
afternoon as south/southeast winds strengthen. Some sparse, light
showers could develop along the sea breeze during the late
afternoon. Included mentions of showers for areas south of I-10
where confidence is greater, though coverage will likely be
sparse, much like today. Showers taper off in the evening with
winds becoming light/variable again Tuesday night.

Light to occasionally moderate onshore winds are expected through
the next several days. Winds could reach Exercise Caution levels
at times. Seas will generally range between 2 and 3 feet
nearshore and 3 to 5 feet offshore. Slight chance of showers and
thunderstorms can be expected daily, with increasing chances
expected during the upcoming weekend. There will also be a
moderate to high risk of rip currents along the Gulf facing
beaches.
