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.

Issued at 1210 AM CDT Wed Jul 1 2026

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
