.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...
(12Z TAF Issuance)
Issued at 525 AM CDT Tue Jun 9 2026

A mixed bag of IFR to VFR conditions as low ceilings and even 
isolated spots of patchy fog creating reduced visibilities prevail
early this morning. Ceilings are mainly an issue for the northern
terminals, but will lift to VFR areawide later this morning. 
Isolated SH/TS are expected to develop near the coast along the 
sea breeze around 16Z and drift northward. Not enough confidence 
on thunderstorm development, so only have PROB30's for SHRA for 
most of terminals in the late morning to early afternoon hours. 
Any SH/TS that develop will dissipate by 00Z with MVFR ceilings 
filtering in again overnight into Wednesday morning. Some 
intermittent IFR ceilings are possible as well for the northern
terminals (CXO and northward). Winds will be southeasterly 
throughout the TAF period with wind speeds increasing to 8-12 kt 
in the afternoon and trending lighter after sunset.

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

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.
