There have been some adjustments to the forecast next week. The good news is that much-needed rainfall is still expected across the western half of the state. Flash Flooding will be a concern across parts of Northwest/West Central Texas as some areas will see rainfall amounts in excess of 8-12" by late next week. The bad news is that a tight gradient may set up along or near I-35. The model guidance has trended much drier to the east of the I-35 corridor over the last several runs. Take a look at the following graphics. The first is the GFS (American) model, and the second is the CMC (Canadian) model. Both graphics show the forecast rainfall between now and Friday morning. The amounts are in millimeters, so I posted the inch equivalents next to the scale.
Hopefully, the heavier rainfall makes it farther east than what the models show because North and Central Texas could certainly use it. Regardless, cooler temperatures can be expected next week. It will feel a lot more like fall than this past week.
