Today's Severe Weather continues to slowly wind down. There were several Supercells that impacted southern portions of North Central Texas this afternoon and evening. Up to Tea Cup-size Hail (3.00") fell south of Copperas Cove with other Hail and Wind reports scattered across the area. The current Severe Thunderstorm Watch remains until 11:00 PM this evening. What is tomorrow looking like? Well, parts of Texas could see Severe Weather Sunday afternoon and evening. We could see a couple Supercells develop Sunday afternoon in North Texas, particularly north of the I-20 corridor. Similar to today, any storm that develops and becomes surface-based could produce Very Large Hail, Damaging Winds, and possibly a Tornado. This is the latest outlook for Sunday.
I do want to take a minute to share what I am seeing this evening. First, the warm front that made it into the I-20 corridor has been pushed back toward the south. This is due to today's storms and their outflow (rain-cooled air). This boundary will lift back toward the north overnight and tomorrow as the main system approaches from the west. Another surface low should develop early tomorrow in West Central Texas. This feature will lift into the Red River Valley of Northern Texas late Sunday afternoon. Assuming the environment destabilizes in the wake of earlier clouds/rain, this extra lift would likely spark a few storms during the afternoon hours. While storm coverage may be low, anything that develops could become severe. I would not be surprised to see the SPC adjust their risk areas farther west in later outlooks.
We will know more on what to expect in the morning. I will post periodic updates on the Facebook page throughout the day. Be sure to check back from time to time on Sunday.
