Additional Rain and Ongoing Flooding in Texas; Snow in the Southern Rockies

The heavy rain in central Texas will shift slightly providing some relief to flood ravaged areas. Flooding and flash flooding will still be possible across portions of Texas. An upper level low will move east from southern California, which will allow California offshore winds to ease reducing fire weather threats. As this system moves east, snow will increase across the Southern Rockies. Read More >

Overview
From the late afternoon of Friday, April 13, 2018, through the early morning hours of Saturday, April 14, 2018, an outbreak of severe thunderstorms and tornadoes affected the Four State Region. Multiple rounds of severe weather developed and moved across the area. The first round involved several supercells, which developed across North Central Louisiana and South Central Arkansas, mainly east of a line from Magnolia, AR, to Natchitoches, LA. A cyclic supercell developed near Calhoun, LA, and produced multiple tornadoes as it traveled northeast. A NOAA WP-3D Orion Hurricane Hunter aircraft was operating in the Calhoun and Sterlington areas as a part of VORTEX-SE, a research project studying tornadoes and severe weather in the Southeastern United States. The NOAA aircraft visually confirmed multiple tornadoes from the Calhoun supercell.

The second round of severe weather developed across Southeast Oklahoma, Southwest Arkansas, and Northeast Texas. This round consisted of several supercells. One of these supercells produced an EF2 tornado near Umpire, AR.

During the overnight and early morning hours, a large line of thunderstorms called a QLCS (quasi-linear convective system) developed ahead of a cold front and moved across the entire area. Numerous reports of straight-line wind damage were produced by this line. Around midnight, a supercell developed within the line. A long-track tornado (Tornado #8) developed from this supercell and moved across Shreveport, Bossier City, Red Chute, and Princeton. The track was 22.5 miles long. The tornado tracked very close to Interstate 20 through Shreveport and Bossier City before turning northeast. Near the beginning of the damage path, this tornado just barely missed the National Weather Service office on the west side of Shreveport Regional Airport. Snapped trees were found less than 300 yards north of our building. Tragically, a two-year child was killed inside a mobile home park by a falling tree.

This QLCS continued to produce multiple tornadoes across Northern Louisiana and Southern Arkansas as several embedded supercells developed within the line at different points. including another tornado near Sarepta, LA. A mobile Doppler radar operating as part of VORTEX-SE was actively scanning the development of this tornado, and they reported their information to the NWS in Shreveport in real-time during the event. Multiple tornadoes were also produced by an embedded supercell from in North Central Louisiana from near Bryceland, to Ruston, to southern Union Parish near D'Arbonne National Wildlife Refuge. One of these tornadoes (Tornado #17) moved across the same point where the Calhoun supercell produced a tornado (Tornado #2) a few hours earlier.

Survey teams from the National Weather Service office in Shreveport, Fort Worth, and Little Rock were deployed in the days following the storms to assess the damage. The results of the surveys are posted below. This information should be considered PRELIMINARY and subject to change as new information becomes available.

The National Weather Service in Shreveport would like to thank our colleagues from Fort Worth and Little Rock for assisting us with the surveys. We also thank the researchers associated with VORTEX-SE for providing us vital ground-truth reports from the mobile Doppler radars and the NOAA WP-3D aircraft as the storms were ongoing.

Summary:

This tornado started along Roach Road very close to the Lincoln/Ouachita Parish line. The tornado moved east into Ouachita Parish, crossed Highway 151, turned northeast into Union Parish, and crossed Reggie Skains Road.

The tornado continued east and crossed Highway 15 and moved along Highway 552 before lifting at the intersection of Highway 552 and Callaway Road. Most of the damage consisted of snapped and uprooted trees. One very large pecan tree estimated at 100 years old was lifted and dropped onto a residence.

This tornado crossed Highway 15 at nearly the same point as Tornado #2 earlier in this outbreak. Therefore, it was nearly impossible to distinguish between the two separate paths when examining the damage along Highway 15 down to its intersection with Williams Colony Road.

This same parent thunderstorm also produced Tornadoes #12, #14, and #16.
