After a bumpy afternoon and evening yesterday, things could get a bit dicey this afternoon once again. The rain from last night cooled the lower levels of the atmosphere causing a boundary, or front to sag south across the Gulf coast. Out to our west we are watching a disturbance move through the upper levels of the atmosphere and this will help drag that front north as a warm front later this afternoon. There are two areas of concern for severe weather this afternoon. The first is across the southern counties of East Texas where this disturbance will move through this evening. This will cause the air to rise and form strong to severe thunderstorms, starting around 5:00PM in our extreme southwestern counties. The main threat with these storms will be strong gusty winds and isolated weak tornadoes.
The second area of concern is across the I-20 and I-30 corridors where the warm front is expected to move through this afternoon and evening. Some breaks in the clouds this afternoon should allow enough sunshine to warm temperatures into the mid to upper 70s. This along with cold mid level atmospheric temperatures will provide a large amount of energy and instability needed for thunderstorm growth. The only thing lacking is enough forcing to lift the air and get storms cranking. As the warm front moves through, and an increase in upper level winds move in, I think a few storms will develop. We will have to watch these very closely as there will be the potential for large hail, gusty winds, and tornadoes. In both areas storms should diminish around midnight. Another storm system will move towards East Texas tomorrow bringing another chance of severe weather.
Once this second storm system moves through the threat of severe weather is over for the weekend and temperatures will cool down. We will see lows in the 30s in most locations this weekend so get ready. Stay tuned to KLTV and KLTV.com for the latest on our severe weather threat.
