TYLER, Texas (KETK) – A line of showers and thunderstorms is set to push through our area late Sunday night into early Monday morning. Storms within the line will bring the threat of damaging, straight-line winds to East Texas. Spin-up tornadoes and large hail cannot be ruled out, with the tornado threat staying mainly north of I-20.
Current Weather Analysis
A Tornado Watch has been issued for parts of NW Texas and central Oklahoma until 10 PM Sunday. Storms are blossoming in this area, stretching back into the Texas Big Country region.
Now, a new Tornado Watch is in effect for west counties of East Texas until 2 AM Monday.
Storms are set to enter the DFW area/I-35 after 8 PM, and then cross I-45/enter East Texas after 11 PM.
A very potent upper disturbance is moving out of the Desert Southwest and entering the Southern Plains now. This will act as the source of upper-air support for strong to severe storms for a large portion of the south-central U.S. this evening and overnight.
At the surface, a dryline has set up in west-central Texas. A dryline separates warm-moist air from hot-dry air. This boundary is where storms are expected to grow and increase for the evening hours.
While rain and storms have been ongoing in the Texas Panhandle & far east New Mexico, newer storms will develop and become much stronger along the dryline.
Later tonight, a cold front will push through southern Oklahoma and Texas, and a line of storms will develop just out ahead of it. This looks to move into East Texas after 11 PM tonight into early Monday morning.
Damaging straight-line winds will be the primary threat with this line of storms. There will be enough low-level rotation, especially north of I-20, to allow for the possibility of spin-up tornadoes. The main timing for this looks to be between 10 PM Sunday and 7 AM Monday, with a gradual weakening closer to daybreak Monday.
As we get closer to sunrise on Monday, the cold front’s upper-level support will lift north into Missouri and help weaken the storms.
WHAT YOU NEED TO DO
Keep up to date with the latest forecast. Although the tornado threat is not that high, go over a tornado safety plan with your family. Make sure to identify your tornado safe place before the storms so everybody in your household knows where to go if a tornado warning is issued for your area. In a sturdy structure, that safe place is the most interior room on the lowest floor of the home.
