EF1 tornado, Marshall Northeast to Woodlawn, Texas, May 8, 2019

1. EF065 to 85 mph

   Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

2. EF186 to 110 mphthis tornado

   Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

3. EF2111 to 135 mph

   Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.

4. EF3136 to 165 mph

   Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.

5. EF4166 to 200 mph

   Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

6. EF5over 200 mph

   Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.

7. Unrated

   The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

28 damage points were recorded along this path by NWS SHV, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 107 mph.

• blown west to east. could be straight line
• tree blown to the se. could be straight line
• tree top broken. blown to east
• obvious twisting of tree damage

A strong upper level trough of low pressure extending from the Intermountain West into the Four Corners Region energized the southwest flow aloft across the Southern Plains during much of the day on May 8th, with a strong low level jet sustaining a mesoscale convective complex (MCS) across much of Oklahoma into Northcentral Texas south into the Texas Hill Country. While these storms gradually weakened after daybreak as a cold pool from these storms propagated southeast into the region, additional upper level disturbances ahead of this trough interacted with ample moisture and instability near this cold pool to intensify these showers and thunderstorms, some of which became severe with damaging winds as they moved across portions of East Texas, Southwest Arkansas, and North Louisiana. Strong low level shear was also present within the moderately unstable air mass, with discrete supercell thunderstorms developing across extreme East Texas and North Louisiana. This resulted in several reports of tornadoes, with two separate tracks found across Northern Harrison and extreme Northeast Panola Counties, before the storms moved into North Louisiana by mid-afternoon. Locally heavy rainfall from the stronger storms within a short period of time also resulted in localized flash flooding across portions of Cass County, with flash flooding also reported across Eastern Harrison and Panola Counties during the early morning hours on May 9th as additional showers and thunderstorms redeveloped and moved repeatedly over the same areas. During the evening hours on the 9th, isolated severe thunderstorms developed over portions of Deep East Texas along old outflow boundaries from the storms earlier in the day. These storms produced large hail in extreme Southern Sabine County and Central Nacogdoches County before diminishing by midnight.

An EF-1 tornado with maximum estimated winds around 105 mph developed within a squall line of thunderstorms that produced sporadic straight line wind damage mainly to trees across Northern Harrison County. The tornado touched down a few miles west of Highway 59 on FM 1997, tracking east across County Road 4000 where several trees were snapped and uprooted. As the tornado crossed Highway 59 along the north side of Suburban Acres Road, numerous hardwood trees were snapped with a few homes receiving roof damage due to trees or large limbs falling on the structures. The tornado continued to uproot and snap several more trees before crossing County Road 2012, and lifting shortly thereafter.

13 minutes of warning. NWS SHV issued a tornado warning for this county at 19:23 UTC, 13 minutes before the tornado touched down, in force until 20:15 UTC.

The county was under a tornado watch, issued at 19:16 UTC and running to 00:20 UTC.

The Storm Prediction Center had this point in a Slight Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 16:49 UTC.

17 more were confirmed in the United States that day.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
