225 FXUS64 KCRP 291135 AFDCRP Area Forecast Discussion National Weather Service Corpus Christi TX 635 AM CDT Wed May 29 2024 ...New AVIATION... .SHORT TERM... (Today through Thursday) Issued at 355 AM CDT Wed May 29 2024 Key Messages: - Marginal risk of severe weather through tonight (northern counties). - Moderate risk of rip currents along area beaches through Thursday. The MCS has drifted apart leaving behind a wake low across the area. Current observations have wind gusts up to 45-50 MPH over portions of the Coastal Plains, with winds now beginning to pick- up along the coast. A Wind Advisory is in effect through 6 AM for counties west of Bee to Jim Wells, and through 7 AM from Kleberg to Refugio to Aransas. As of writing, wind gusts are reaching 35-40 MPH at the CCIA. Although convection has wained, a few showers and thunderstorms continue to impact the coastal waters and portions of the Rio Grande Plains (mostly west of the border). Another ripple on the generally northwesterly flow aloft can be expected tonight through Thursday, but it will be weaker with most of the energy staying north of the area. Nevertheless, have maintained a 20-40% chance of showers and thunderstorms through the period, given how the systems have been behaving over the past few days as there is plentiful instability and moisture to work with. SPC has the northern half of the CWA under a Marginal risk for severe weather through tonight. In regards to the heat indices today, these are forecast to remain below 110 degrees across most of the area due to cooling from the storms earlier in the night. A few locations may briefly reach 110-114 degrees along the coastal counties, but should be brief enough not to grant another Heat Advisory at the moment. A Moderate risk for rip currents remains in effect through Thursday along area beaches. && .LONG TERM... (Thursday night through next Tuesday) Issued at 355 AM CDT Wed May 29 2024 Key Messages: - Moderate to extreme heat related impacts continue this week through the middle of next week. - Marginal Risk for Severe Thunderstorms Friday Night A mid-level ridge positioned over Mexico will maintain hot and humid conditions over South Texas through the upcoming weekend. A series of shortwave troughs traversing the northern periphery of this ridge will bring chances for showers and thunderstorms mainly during the overnight hours from Friday Night through Sunday Night. Best chances for convection will be across the western and northern parts of our CWA. Cannot rule out a threat for strong to severe storms as well. SPC currently has northern portions of our CWA in a marginal risk for Friday Night. The mid level ridge will become amplified over the southern Rockies by early next week which will dry our mid levels and increase the heat. Heat advisory conditions will be possible on Friday and again Monday and Tuesday with Excessive Heat Warnings possible by the middle of next week. In addition to the heat, hazy conditions will continue due to the fires in Mexico. Please take pre-cautions to protect yourself when outdoors for prolonged periods. && .AVIATION...

A brief period of MVFR levels is forecast by early Thursday morning. A few showers remain possible out west early this morning, and again tonight in response to a few passing disturbances. Otherwise, light and variable winds this morning will become breezy again by the afternoon, before decoupling overnight. && .MARINE...
