.DISCUSSION...
Issued at 1210 AM CDT Wed Jul 1 2026

Overall, only minor adjustments were made with this forecast
package. A few showers and thunderstorms developed across western
and central portions of the Western Pineywoods yesterday afternoon
and evening. Quiet conditions are in place across the area tonight
with no showers present across the region.

The mid-level ridge has centered itself over the Ohio Valley and Mid-
Atlantic regions, leaving southeast Texas on the southwestern
periphery. The ridge will continue to shift eastward through
Thursday afternoon before reorienting itself across our region this
weekend. Isolated seabreeze showers and thunderstorms are
expected this afternoon with some scattered coverage across the
northern Golden Triangle. As the ridge relaxes on Thursday, richer
moisture will move into the region along with a subtle impulse.
This will bring scattered showers to the Gulf Coast and southern
Western Pineywoods, and numerous showers across far eastern
Liberty and Chambers Counties. Isolated to scattered showers are
expected along and east of I-45 up to Madison County. Rain chances
look to briefly diminish Friday and Saturday and then increase
Sunday afternoon and into early next week.

The HeatRisk continues to remain the main threat for the region.
Peak heat index values will continue to range between 102-107F (39-
42C) today and Thursday, with values increasing to 105-110 (40-43C)
on Friday and into the weekend. The highest values will generally be
seen where seabreeze showers do not occur. Forecast trends will
continue to be monitored to see if Heat Advisories will be necessary
for the holiday weekend. Frequent hydrating and shade/AC breaks will
be key to beating the heat.

The rip current threat has renewed overnight. There is a high risk
of rip currents in place for Gulf facing area beaches until 10 AM
this morning. After mid-morning, sea heights look to fall once again.|

.AVIATION...
(06Z TAF Issuance)
Issued at 1257 AM CDT Wed Jul 1 2026

Latest surface obs around the region show widespread VFR
prevailing. Patchy stratus is forecast to develop before sunrise,
but should mainly impact northern and western terminals briefly,
specifically KCLL, KUTS, KCXO, and perhaps KDWH, through mid/late
morning. Isolated showers and thunderstorms are forecast to
develop with diurnal heating, but chances are too low to mention
in TAFs. Winds will remain light out of the southeast, picking
back up late this morning and through the afternoon, sustained
around 5-10kt with gusts up to 20 knots at times.

.MARINE...

Gentle to moderate breezes will vary from a southerly to
southeasterly direction with 2-3 ft seas along with chances for
scattered showers/thunderstorms on Thursday, primarily over the
nearshore waters and bays
