Marine Weather and Tide Forecast for Arroyo Gardens, TX

DISCUSSION
Issued at 1110 AM CST Thu Feb 12 2026

Warm and dry conditions will persist through late next week. This weekend, an upper level shortwave is expected to move over Texas, which will bring a weak cold front to Deep South Texas on Saturday.
Prior to the cold front's arrival, high temperatures are expected to reach the upper 80s/lower 90s Saturday afternoon. The front is expected to slightly cool high temperatures into the mid-80s for a few days before temperatures creep back into the upper 80s/low 90s by next Tuesday. Low temperatures will cool from the the upper 50s/lower 60s to the low 50s Monday and Tuesday mornings.

Rain and thunderstorm chances associated with this shortwave/frontal passage appear to be primarily outside of the CWA, since the jet streak and best upper-level divergence is expected to pass to our north-northeast with the shortwave's ejection. Model guidance seems to be consistent with this trajectory; therefore precipitation chances for Deep South Texas remain below 20% for Saturday. A shower or two cannot be ruled out in very northern portions of the CWA, however, particularly in Brooks and Kenedy Counties, as these areas are close to portions of Corpus's CWA under a general thunderstorm risk for Saturday. However, none of our CWA is included in this risk at this time. If, for some reason, model guidance were to trend the shortwave's ejection a little further south, we could potentially see an increase in shower and thunderstorm potential for Saturday. However, model guidance continues to keep higher rain chances and thunderstorm risk to our north. We will continue to monitor.

There is some concern for for fire danger potential this weekend associated with the frontal passage. Wind speed guidance over the past few days has trended wind speeds slower, which is better for inhibiting fire spread. At this time, it is uncertain if any fire danger products will need to be issued. If so, the greatest likelihood would be for Sunday, when wind speeds could approach 15 knots in some areas. Humidities are expected to fall between 20-30% for most of the CWA Sunday (excepting coastal areas), which means that freeze-cured fuels could still catch quickly even if Fire Danger Statement criteria is not met. Therefore, outdoor burning is still strongly discouraged.

Following the weak frontal passage, upper level ridging with semi- zonal flow is expected for the region next week, which will keep the weather warm and dry through at least the latter part of the week.
Mostly sunny to partly cloudy conditions are expected, with winds shifting from the north-northeast on Sunday and Monday back to the east-southeast by Tuesday.
