Stormy Western U.S.

An active and complex weather pattern is in store this weekend through next week, as multiple storms track from West Coast to East Coast. The activity starts today as a vigorous system moves through north-central California into the Intermountain West with rain, perhaps a few thunderstorms and heavy mountain snow. This system will move into the Upper Midwest tomorrow with a swath of heavy snow. Read More >

April 13th &14th, 2018 Severe Weather Event

 

Event Summary

During the evening hours of Friday, April 13th, scattered supercells developed across northeast Louisiana within the broad warm sector of a strong surface cyclone centered near the Kansas/Nebraska border. These storms exhibited rotation almost immediately, and began producing tornadoes across northern Louisiana. Two tornadoes occurred in the NWS Jackson forecast area in association with a cell that tracked from near Rayville, LA north northeastward along the Boeuf River. These storms also produced strong wind as they continued into southeast Arkansas. Overnight, as the cold front associated with the storm system began to advance eastward, a quasi-linear convective system developed over the ArkLaTex and advanced eastward. These storms reached the western portion of the NWS Jackson forecast area after 2:30 am on Saturday, April 14th. Six tornadoes occurred during the early morning hours across southeast Arkansas and northeast Louisiana in association with this line of storms. The storms continued to produce damaging straight-line winds, knocking down trees and power lines in many areas, through the morning hours as it continued eastward into Mississippi. A few additional tornadoes also developed along the line, including one in Flowood, one near Noxapater, one in western Lamar County, and an EF2 tornado in Meridian.

Track Summary

This tornado began near Jackson Preparatory School along Lakeland Drive and subsequently tracked east-northeast just north of the Lakeland Drive on its roughly 6 mile path length through west-central and into central Rankin County. Most of the damage was limited to trees with the most significant tree damage involving snapped and uprooted hardwood trees, yielding a low end EF-1 designation. There was scattered minor structural damage, mainly to roofs, as large limbs and trees fell upon residences.
