Trees and power lines were downed in Jena.
A very large tree was blown down along Highway 127 south of Jena, with a power pole snapped and power lines also downed in that same area.
Episodes
Hot and humid conditions continued from the final day in August through the first few days of September, with temperatures climbing into the mid 90s across North-central Louisiana. Oppressively high dewpoints in the mid 70s in wake of a warm frontal passage on August 31st shifted back north across much of East Texas and North Louisiana, which when combined with the very hot temperatures, resulted in heat indices ranging from 100-107 degrees across these areas. This was brief though before scattered showers and thunderstorms and associated cloud cover ahead of a closed upper low pressure system over the Four Corners Region affected portions of North Louisiana on the 3rd, resulting in slightly cooler conditions with lower heat indices. Due to the extensive power outages across much of North Louisiana in wake of Hurricane Laura, the NWS Shreveport Heat Advisory criteria was temporarily lowered to heat indices greater than or equal to 100 degrees for parishes where at least 10% of the parish was without power.
Milder and more humid air surged north across North Louisiana, East Texas, Southwest Arkansas, and Southeast Oklahoma during the daytime hours on January 18th, as a strong low level jet developed ahead of a vigorous upper level trough that moved into the Southern Plains. The attendant surface low developed over the Eastern Texas Panhandle on the 18th as well, which tracked east southeast along the middle Red River Valley before lifting northeast into Eastern Oklahoma. This allowed a strong cold front to move into Southeast Oklahoma, East Texas, and Southwest Arkansas around midnight on January 19th, before spreading southeast across Southcentral Arkansas and North Louisiana during the overnight and early morning hours. Surface based instability return ahead of the front was minimal, but the presence of strong shear and strong instability aloft along and just ahead of the front/upper trough allowed for scattered to numerous showers and thunderstorms to develop over Southeast Oklahoma and East Texas during the late evening through the overnight hours on the 18th-19th, which quickly spread east northeast across Southwest Arkansas and North Louisiana. Isolated strong to severe thunderstorms were embedded within the increased convection over these areas, which resulted in a large tree and power lines being blown down just south of Jena in La Salle Parish Louisiana.
Scattered showers and thunderstorms developed during the mid and late afternoon hours on Monday, August 11th, near and south of a weak surface boundary that was reinforced south from storms that developed the previous day. This large boundary extended along the Interstate 20 corridor of North Central and East Texas into North Louisiana, with strong daytime heating atop a very moist air mass contributing to moderate instability, resulting in shower and thunderstorm development. These storms produced numerous outflow boundaries across North Louisiana, which allowed for these storms to become more widespread and form a small mesoscale convective system, as they accelerated south across North Central Louisiana. Damaging winds were noted at times, resulting in downed trees and power lines over the area. A second cluster of showers and thunderstorms developed over East Central Texas south of the stationary outflow boundary, and quickly spread east southeast across East Texas south of Interstate 20. Some of these storms also became severe over Nacogdoches, Shelby, and Sabine counties, where downbursts downed numerous trees over these areas.
Severe thunderstorms erupted across portions of northwest Louisiana due in part to a shortwave trough passing through the Lower Mississippi Valley. This trough of low pressure aloft interacted with a nearly stationary front and daytime heating to aid in the development of thunderstorms. A few of the storms became severe, producing damaging downburst winds which blew down numerous trees and powerlines across.

Power Outage FAQs
What is Power Outage?
Power outage (also called a power cut, a power blackout, power failure or a blackout) is a short-term or a long-term loss of the electric power to a particular area.
What Causes Power Outages?
- Severe weather (high winds, lightning, winter storms, heat waves, rain or flooding can cause damage to power lines or equipment);
- Other damage to electric transmission lines (vehicle accidents, trees, and animals can cause damage to power lines or equipment);
- Repairing, maintenance or upgrades on power lines and equipment.
What are the Top Outage Safety Tips?
- Stay away from the downed power lines, park vehicles in protected areas;
- Unplug appliances and electronics, limit cell phone use to conserve battery life;
- Use portable generators outdoors only, well away from open windows and doors;
- Pack perishable foods into a cooler, keep refrigerator and freezer doors shut as much as possible.
