11 PM Update on North Texas Snow

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....

Very Cold Temperatures and Hard Freeze across Texas on Tuesday Morning

Even though we’ll be quite chilly tonight into Monday, we’re most concerned about the very cold temperatures that will exist across all of Texas by Tuesday morning.

Those two things allow surface heat to radiate upwards and thus cool the surface quickly. Freezing temperatures are likely south to the Interstate 10 corridor and parts of Deep South Texas. Below average low temperatures and the long duration nature of...

Cold Front brings Storm/Rain Chances to East & Southeast Texas

As David posted yesterday evening, the Storm Prediction Center has placed portions of east and southeast Texas under a standard Slight Risk for severe weather today.  Forcing along the frontal boundary later this afternoon where instability is highest will create an environment favorable for storm development this afternoon.  In addition to storms forming ahead of the front, an area of high-based rain showers are predicted to develop behind the front during the late evening and overnight hours. While the larger risk of more severe weather, including tornadoes, is in Lousiana and Arkansas, the SPC has left Texas in the...

Severe Weather Risk across East & Southeast Texas this Evening

The Storm Prediction Center has issued their standard severe weather risk for much of East and Southeast Texas. This severe weather risk will be caused by the much anticipated cold front moving southeastward into an unstable, moist environment this evening. With the cold front will come the strong forcing needed to help develop a broken to solid line of thunderstorms, known as a squall line. The strongest storms in this squall line will be capable of producing quarter size hail and damaging winds over 60 MPH. Not all the storms will be that strong, though. If any thunderstorms develop ahead of...
