Marine Weather and Tide Forecast for Tierra Grande, TX

LONG TERM
(Friday night through next Wednesday)
Issued at 319 AM CDT Thu May 22 2025

Key Messages:

- Moderate to Major risk of heat related impacts across South Texas through the weekend into Memorial Day.

- Low to medium chance of showers and thunderstorms Monday through the middle of next week.

Overall, very warm and drier conditions can be expected across South Texas this holiday weekend, followed by increased rain chances through much of next week.

Ridging aloft will transition eastward into the Gulf waters late in the weekend with several shortwave troughs then tracking in the flow aloft. A frontal boundary is progged to move over the area sometime between Monday through Tuesday period, followed by a couple of additional shortwaves Wednesday and Thursday. The aforementioned bouts of disturbances in conjunction with above normal moisture (PWATs 1.8-1.9") will result in low to medium rain and thunderstorm chances (20-50%) daily from Monday through Thursday next week.
Although storm totals will generally remain less than a half an inch, WPC has already highlighted the northern half of the CWA under a Marginal (at least 5%) risk of excessive rainfall Monday to Tuesday period.

The Heat Risk will remain at Moderate to Major levels Saturday through Monday, before slightly cooler temperatures return Tuesday through Thursday next week in the wake of the weak boundary. Heat indices will hover around 105-110 through the weekend, peaking at near 110-114 Monday afternoon particularly across western portions of the Coastal Plains and Brush Country. These conditions will require further monitoring for the potential issuance of Heat Advisories.

*Citizens with planned outdoor activities for the Memorial Day weekend should closely monitor the heat conditions, and prepare to adjust plans to accommodate frequent breaks from the heat in cooler locations to avoid heat-related illnesses. Also, if heading outdoors practice heat safety: drink plenty of water, wear lightweight, loose- fitting and light-colored clothing, and apply sunscreen. Never leave anyone in a vehicle unattended and don't forget to check the backseat!
