| Area Forecast Discussion National Weather Service Houston/Galveston TX 635am CDT Sunday May 17 2026 Issued at 1206am CDT Sunday May 17 2026 Prevailing southeast low level flow the past few days has allowed for increasing moisture/cloudiness to stream into the region from the Gulf. We're seeing a few short lived showers Probability of Precipitation up on the radar scope from time-to-time. GOES Total PW loop shows PW's back into the 1.5+ range from around I-10 southward at the current time. These should gradually be rising areawide in the coming days with a persistent fetch of SE winds stretching well into the Gulf. Incoming higher dewpoints will also make for warm, muggy conditions. In terms of rain chances, there's really not much in the way of significant forcing today, so would just anticipate some spotty, isolated showers. On Monday, there's a mix of guidance suggesting a batch of vorticity moving up from Mexico and overhead late tonight- Monday which may allow for slightly better coverage...but still probably not much of overall significance. Things get a little more interesting Tuesday and beyond. In the low levels, we'll see a continued tap of Gulf moisture streaming in. A weakening frontal boundary will sag into north Tx Tuesday, serving as a focusing mechanism for some convection. Remnants of this boundary, and/or associated storm outflows, might make its way closer to northern parts of our area in the mid-late work week. Further aloft, mid-upper trough.iness will generally set up across the Rockies...with a quite messy southwest flow below it traversing our area. Daytime heating, stronger disturbances embedded in this flow, and the remnant front/outflows will likely trigger showers and thunderstorms at times and maybe an MCS (Mesoscale Convective System, a complex of thunderstorms which becomes organized on a scale larger than the individual thunderstorms) or two Tue-Sat. Forecast problem is narrowing down the specifics this far out - especially since it'll probably be run on the mesoscale at times. The forecast grids will indicate good chances of precip, but it VERY likely won't be raining the entire time. In general, I would anticipate mostly scattered diurnally driven shra/thunderstorms. But, with any more potent disturbances, one cannot rule out nighttime activity either. This should mainly be welcome rainfall as we head into summer. On average, it appears areas from about I-10 northward are looking at 7- day totals in the neighborhood of 2-4", and areas further south a bit lower. Localized high totals (in a short time period) can't be ruled out this time of year should any stronger complexes decide to fire. Temperature-wise, we're looking for lows in the 70s and highs in the upper 80s-low 90s. 47 Marine Issued at 1206am CDT Sunday May 17 2026 Seas are currently in the 4-6ft range with SE winds 18g25kt. With the pressure gradient slightly tightening even further...and the fetch of moderate SE winds lengthening, we should see winds/seas build a bit more today and Monday...probably up into the 6-8ft range by then. Will go ahead and issue a Small Craft Advisory now. Beach Hazards Statement will remain in effect too which covers the high risk of rip currents and above normal tide levels. Higher than normal wave run up is anticipated along area beaches. Wouldn't be overly surprised if it nears the 87/124 intersection for a brief period during the next several high tide cycles into Monday. Pressure gradient loosens up a touch toward midweek, so elevated winds/seas will begin to slowly decline. But, we'll also need to be keeping an eye out for increasing shower and thunderstorm chances during that time period. 47 NOAA Houston/Galveston TX Office: Watches - Warnings - Advisories TX...Beach Hazards Statement through Monday morning for TXZ436>439. GM...Small Craft Advisory until 10am CDT Monday for GMZ330-335-350- 355-370-375. |
