Summer-like conditions will continue to be the rule through the forecast period. Above normal daytime highs and overnight lows will prevail, with generally dry weather in place. However, occasional bursts of deep tropical moisture, with precipitable water values nearing two inches, will support highly-isolated showers and thunderstorms along the sea breeze boundary during the daylight hours, and in the form of streamer activity over the lower Texas coastal waters at night.

Additionally, a Moderate Heat Risk can be expected daily, with a general low risk of a Heat Advisory on one or more days.

Finally, sea conditions along the Lower Texas Coast will support a Low to Moderate Risk of rip currents at the local beaches each day.

Favorable marine conditions are expected to continue during the period, with a modest pressure gradient over the western Gulf of America producing light to moderate winds and low to moderate seas along the Lower Texas Coast. Although Small Craft Advisory is not likely to be needed, occasional Small Craft Should Exercise Caution due to winds cannot be entirely ruled out, especially for the Laguna Madre.
