| Area Forecast Discussion National Weather Service Houston/Galveston TX 553am CDT Tuesday April 7 2026 Issued at 1145pm CDT Monday April 6 2026 If you enjoyed Monday's weather then you are certain to love the weather for Tuesday. We start the day with a chill in the air. Much of our northern tier, as well as some rural cold spots in our southern zones, are expected to start the day in the 40s. Meanwhile, morning lows in the city and near the coast are expected to be in the 50s (60s at the beaches). By afternoon, expect temperatures in the 70s with continued low humidity. Get outside and enjoy it! The recent northeast flow will veer easterly today. But by Wednesday, we will find ourselves in a southeasterly wind regime, bringing warm and more humid air into our region from the Gulf. Temperatures should be near 80 with dew points approaching 60. Pretty nice for SE Texas but definitely a sign of an air mass change. Also couldn't rule out a few showers on Wednesday as well. Persistent, deep, moisture rich SE flow will send PWATs (Precipitable Waters) into the 1.0 - 1.5 inch range Thursday into the weekend while a series of vort maxes embedded in the S to SW flow aloft push over our area. This should allow for some enhanced shower/thunderstorm chances as we approach week's end. Given the moisture profile, we couldn't rule out heavier shower and thunderstorm activity, particularly late Friday into Saturday. This will be something to watch as the week progresses. Regarding temperatures, expect increasingly warm and humid conditions, with highs generally in the low 80s during the second half of the week. Self Marine Issued at 1145pm CDT Monday April 6 2026 An easterly 10-15 knot (occasionally higher) wind will veer southeast by Wednesday. By Thursday and Friday, a fairly large 15-20 knot east to southeast fetch is expected to materialize over the Gulf, likely enhancing waves and swell as we approach the end of the week. Winds may increase further by the weekend. Some of our wave models suggest seas could reach 7-8 feet offshore. In addition increasing winds and waves, shower and thunderstorm chances will be increasing during the the second half of the week as well.
