| Area Forecast Discussion National Weather Service Corpus Christi TX 608am CDT Sunday April 28 2024 Long Term (Monday night through next Saturday) Issued at 219am CDT Sunday April 28 2024 Key Messages: - Low chance of showers and thunderstorms expected this week - Minor coastal flooding possible through midweek A more zonal flow will develop Monday night and persist into the week. Moisture and warm air will continue to stream into the area with southeast flow which could lead to diurnal showers and thunderstorms for Tuesday. A brief break in convection is still expected Tuesday night and Wednesday as high pressure noses into the area. A series of shortwaves will move across South Texas beginning Wednesday evening , leading to a 15-30% chance of showers and thunderstorms through the work week. The persistent southeasterly flow will continue to help push long period swell ashore through the middle of this week. Minor coastal flooding and a high rip current risk will be possible through Wednesday, when swell periods should diminish. Temperatures will be warm through the upcoming week, with highs in the mid 80s to upper 90s daily across South Texas. I hate to bring it up this early, but it looks as though heat index values will reach 100-105 across the Rio Grande Plains through early this week. Some relief may be in sight as a weak cold front approaches the area over the weekend. Model guidance isn't giving us much hope for much cooler conditions, but drier air may filter in as the cold front fizzles out over or just north of the area leading to cooler apparent temperatures. We will have to wait and see how this front actually behaves. Marine Issued at 219am CDT Sunday April 28 2024 Strong onshore flow with occasional gusts to 35 knots will be possible through this morning. Seas will remain elevated through Monday morning, therefore, the Small Craft Advisory will remain in effect. Onshore flow becomes weak to moderate tonight, persisting at these levels through the end of the week. There is a 15-40% chance of showers and thunderstorms daily across the waters through mid week. NOAA Corpus Christi TX Office: Watches - Warnings - Advisories TX...Coastal Flood Advisory until 7pm CDT this evening for TXZ345- 442-443-447.
