| Area Forecast Discussion National Weather Service Houston/Galveston TX 1150pm CDT Fri April 19 2024 Long Term (Sunday through next Thursday) Issued at 233pm CDT Fri April 19 2024 Rain should be coming to an end Sunday morning as this system pushes out of here and the front makes further southward progress off the coast. Cooler, drier air will be filtering in, though clouds might hang around for a good part of the day before scattering out Sunday night. Surface high pressure will begin moving off to the east Monday, though we'll still probably see some recycled drier air backdoor into parts the region at times. It probably won't be until midweek when we see more noticeable dewpoint modifications and warming overnight lows. A prevailing onshore flow will be the rule during the second half of the workweek into the weekend. Slight chances of mainly diurnally driven rain shower and/or thunderstorms are a possibility, though some subtle mid- upper ridging will be a limiting factor. 47 Marine Issued at 233pm CDT Fri April 19 2024 Onshore flow will persist into Saturday. Periods of haze and fog can be anticipated but it is not expected to become dense. The next cold front and associated showers and thunderstorms will push off the coast late Saturday night followed by moderate north and northeast winds and building seas in its wake. Small Craft Advisories will likely be required. As high pressure begin moving east of the region on Monday, onshore winds will resume. As the pressure gradient tightens Wed-Fri, look for a fetch of moderate southeast winds to set up across the Gulf during the second half of the week. 47 Hydrology Issued at 333pm CDT Fri April 19 2024 Conditions are favorable for some locally heavy rain Saturday evening an overnight. Though there is some uncertainty exactly where it will fall, latest guidance tends to favor locations north of I-10. Several inches of rain in a short time period will runoff and could pose a flash flood threat. Residents north of I-10 should be on the lookout for rises on area creeks, streams and rivers. Contingency forecasts highlight the potential for minor river flooding. Additional impacts are possible for smaller tributaries. Lastly, area reservoirs are full, so any runoff will need to be released. Pay attention to updated forecasts. 47/KLG NOAA Houston/Galveston TX Office: Watches - Warnings - Advisories TX...None.
