Squall Line Tornado Threat to Intensify After Dark Across Texas and Louisiana as Damaging Winds Sweep East Saturday Night
TEXAS — A developing squall line is expected to sweep across the state Saturday before intensifying after sunset and pushing into Louisiana, bringing the risk of damaging straight-line winds and isolated tornadoes through the evening and overnight hours.
Forecasters indicate that storms will remain active through much of the day across Texas, but the most concerning period appears to be late afternoon into the nighttime hours — roughly between 5 p.m. and 2 a.m. — as environmental conditions become more favorable for rotation.
Storms Strengthen as They Move East
Meteorologists say that about one to two hours before sunset, the squall line is expected to encounter deeper moisture while the low-level jet strengthens. That combination often enhances wind energy and increases the chance of embedded circulations within a line of storms.
As the system pushes east from areas near Houston, Lufkin, Tyler, and Texarkana toward western Louisiana — including communities near Shreveport and Alexandria — the threat for stronger wind gusts and brief tornado spin-ups may rise.
Isolated QLCS Tornadoes Possible
While this is not expected to be a widespread tornado outbreak, forecasters are warning that a few QLCS (Quasi-Linear Convective System) tornadoes could develop within the squall line.
These tornadoes typically form quickly within fast-moving lines of storms and can be difficult to detect visually at night. Straight-line winds will likely be the primary hazard, but rotating segments embedded in the line could produce brief tornadoes, especially after dark. Communities in eastern Texas and western Louisiana should stay weather-aware through the overnight hours.
Damaging Winds Also a Major Concern
In addition to the tornado threat, damaging wind gusts capable of downing trees and causing scattered power outages are possible as the line accelerates eastward.
Storms moving at a steady pace combined with strengthening upper-level winds could result in wind damage over a broad area rather than isolated spots. Residents are urged to keep weather radios on, enable emergency alerts on mobile devices, and have a safety plan in place before storms arrive.
