Rain Chances Continue Through Early Thursday

Showers and a few thunderstorms continue this morning across portions of the eastern half of Texas. After six inches of rain in parts of Houston this morning we’ve seen flash flooding during the morning rush hour… again. Houston will experience a break in the rain later this morning before a second round moves in early this afternoon. We note that any additional rainfall will likely result in a renewed threat of flooding. Further west in Central Texas we’re looking at that second round of precipitation. Minor flooding has been reported in parts of Austin this morning, but much less so than in Houston. A flash flood warning remains in place for the Houston metro through 10:15 AM. We should see those conditions improve by lunch, but additional rain may result in new flooding conditions by this afternoon in some locations. A final piece of upper level energy will swing through tonight before our first upper level storm system exits the region. This final wave could bring additional showers to the eastern half of Texas tonight. An additional one half inch to one inch of rain could occur with this round tonight. Widespread flash flooding is not expected, but we may see very localized problems develop if additional rains move over a location that’s already saturated. By the afternoon hours Thursday we should see most precipitation exiting Texas to the...

Numerous Showers and Thunderstorms Today and Tonight

An active weather pattern will continue over the next week with no signs of another arctic outbreak in that timeframe. A trough is sitting off to our west in Mexico extending north to southern Arizona. A southwesterly flow ahead of that system is overspreading Texas. At the surface we have a stationary front bisecting the state with copious amounts of moisture in place. This system will bring a good chance of precipitation today, tonight, and into Wednesday. Showers and thunderstorms are likely today in the Permian Basin east through the Concho Valley, Hill Country, Central Texas, South-Central Texas, into the Brazos Valley, East Texas, and Southeast Texas. Scattered showers are expected in Southwest Texas, West Texas, and with scattered storms possible in the Middle Coast. Numerous showers and thunderstorms can be expected tonight with locally heavy rainfall along the Interstate 35 corridor from Laredo north to the Red River. High rain chances will also extend into Northeast Texas, East Texas, the Brazos Valley, Southeast Texas, the Middle Coast, and to a slightly lesser extent westward into the Concho Valley, Big Country, West Texas, and Permian Basin. Rain chances will shift east of Interstate 35 on Wednesday and continue into Thursday across Northeast Texas, East Texas, Southeast Texas, into Deep South Texas. The Storm Prediction Center has a marginal risk of severe weather in place this afternoon across South Texas,...

9:45 PM Severe Weather Update

The leading edge of the squall line extends from near Carrolton to Duncanville to Itasca to Clifton to Burnet to Boerne to near Hondo. The line as a whole is moving east around 25-35 MPH, but individual cells in the line are moving northeast. Not all storms in the line are severe, and some parts of the line are actually pretty weak. The threat for severe weather should decrease as storms move east of Interstate 35 due to low instability values. However, wind shear values are very strong and may help to partially compensate for weak instability. That’s why we’ll be watching any discrete storm for signs of rotation. Lets chat about a few sections of the squall line. The line itself is moving through the D/FW Metroplex as I type this. Strong winds up to 65 MPH and brief spin-up tornadoes are possible along the leading edge of the line from McKinney south through Dallas to Waxahachie. The safety precautions are the same regardless and I would advise moving away from windows and into an interior room. This squall line will continue to move east at about 30-40 MPH with rain continuing for an hour or two behind it. The threat for severe storms should decrease as storms move east of the metroplex, but damaging wind gusts may continue even though instability values are low. At the same...
