Marine Weather and Tide Forecast for Christoval, TX

SHORT TERM
(This evening through Tuesday)
Issued at 1226 PM CDT Mon Sep 21 2026

Early this afternoon skies were sunny to partly cloudy with temperatures in the mid 80s. At the upper levels, the flow was quasi- zonal with a weak shortwave moving across Kansas and Oklahoma. At the surface, a frontal boundary was moving southward through the Big Country. This front will continue moving southward this afternoon and early evening. Showers and storms should develop along this front over the Concho Valley and Heartland this afternoon. Any storms that develop could produce locally heavy downpours and brief gusty winds, with occasional lightning before dissipating late this evening. The front should continue moving southward overnight and reach the I-10 corridor by Tuesday morning. Elevated instability of around 2000 J/kg will exist behind the front so another round of scattered showers and thunderstorms is expected to develop by the afternoon. PWAT values will range from 1.5-1.8 inches, which could lead to pockets of heavier rainfall, mainly south of I-20. Depending on where stronger cells develop, rainfall amounts could range from just a few hundredths to around an inch. Aside from the rainfall, high temperatures are expected to reach the low 90s in a humid airmass. However, depending on when rain and cloud cover develop, this could hold down the temperatures a bit.

LONG TERM
(Tuesday night through next Monday)
Issued at 1226 PM CDT Mon Sep 21 2026

The pattern should become much drier for the latter part of this week as the front lifts back to the north. Upper-level ridging will start building back in across Mexico and southeast Texas starting Wednesday while troughing will be located over the west coast.
This setup will place the region in southwest flow aloft and allow a feed of Pacific moisture into the Panhandle and northwest Texas.
Most of our forecast area should remain dry and warm with highs in the mid 90s. However, some low (<20%) chances for showers and thunderstorms will continue for the Big Country and western Concho Valley Wednesday through Friday. Looking ahead to the weekend, the upper-level flow should become quasi zonal again as the ridge starts to break down. Models indicate another cold front potentially intruding into Texas over the weekend which would result in low (20- 30%) chances for rain showers returning to the forecast.

SJT: VFR conditions prevail through the forecast period. Scattered showers and thunderstorms are expected to develop along an incoming front this afternoon and evening. Confidence in nearby shower and thunderstorm development remains highest at KABI and KSJT, so have maintained the PROB30s for those sites. Expect gusty winds and some reductions to visibility associated with convection. Otherwise, light southerly to southeasterly winds become easterly to northeasterly this afternoon and evening behind the incoming front.
