A high-resolution model, known as the High Resolution Rapid Refresh (HRRR) has gotten snow fans talking this evening. It is showing a widespread area of snow moving over much of North Texas by early Monday morning. Since a news station in D/FW has shared this information without sharing any off the details, I wanted to briefly provide an evening update. Right now, light to moderate snow has dumped between a quarter and three-quarters of an inch of snow on grassy areas in the Texas Panhandle. Roadways remain east of Amarillo, although I-40 west of town is having some issues. As we continue into early Monday, the storm system responsible for the snow will begin weakening. That combined with low moisture values over North Texas screams that any snow that occurs will not accumulate or become problematic for drivers.
The majority of model guidance continues to show that light snow will be possible along and north of Highway 380 in North Texas with flurries as far south as Interstate 20. I cannot rule out a dusting of snow in some areas, but it will melt within minutes of the snow falling. We’ll be here all night providing updates and will let you know if anything changes.
For what its worth, here is the model graphic I’m referring to in this blog post.
