EF2 tornado in Cherokee County, Texas

The same storm that produced an EF-2 tornado over Southern Cherokee County about 6 miles south southwest of Alto produced another EF-2 tornado with maximum estimated winds near 120 mph across the southern and western sections of the city of Alto, where it damaged structures along Highway 21, Blaton Street, and Putnam Avenue. Damage included shifting a single family home off of its foundation and significant roof damage to another home on Quincy Avenue. Several other homes sustained structural damage as the tornado tracked across the west side of Alto and then crossed Highway 69. The tornado then moved across the Alto Independent School District (ISD) and damaged its gymnasium and roofs to structures on the campus. It was near the Alto ISD where a second stronger tornado crossed paths with this tornado as it tore through the western and northern sections of Alto just over an hour later.

A strong upper level trough entered the Southern Plains during the afternoon hours of April 12th, which allowed southerly low level winds to gradually return warm and moist air from the Gulf of Mexico north into East Texas and North Louisiana. An upper level disturbance ejecting northeast ahead of the trough across portions of East Texas and North Louisiana during the early morning hours of April 13th carried enough elevated instability, shear, and forcing north of an advancing warm front over Southeast Texas and South Louisiana, such that scattered strong to severe thunderstorms developed, with numerous reports of large hail and occasional damaging winds received. The warm front continued to gradually mix north northwest into East Texas and Northcentral Louisiana by late morning and early afternoon hours, with a very warm, moist, and unstable air mass noted over Deep East Texas and portions of Northcentral Louisiana south of the front. Coupled with even stronger forcing and low level shear ahead of the approaching upper trough, additional strong to severe thunderstorms developed near and south of the front from late morning through the afternoon, producing numerous reports of damaging winds with several tornadoes across portions of East Texas. These showers and thunderstorms diminished by early evening with the departure of the trough, and the arrival of an associated cold front which brought about cooler, drier, and more stable air southeast into the region.
