We’re seeing first signs of our next wave of precipitation develop from Big Spring east to Sweetwater. This is a sign that the upper level lift with our next storm system is approaching the region. Through 3 AM we’ll likely see widespread precipitation begin developing across the Permian Basin north into the South Plains. That activity will spread east into the Big Country and Concho Valley. With surface temperatures in the low 20s anything that falls will be frozen and accumulate on nearly every surface.
The activity will begin pushing into North and Central Texas after 4 AM with sleet and some freezing rain where temperatures are below freezing. At this time it looks like we should see the activity moving into the D/FW Metroplex and the Interstate 35 corridor from Waco northward around the time morning rush hour starts. With elevated instablity in place we will likely see some thunderstorms. These thunderstorms will have the potential to cause rapid accumulation of sleet where they track.
As sleet falls it will accumulate on surface roads and bridges. We already have some icy spots in the D/FW Metroplex and all across the Big Country, Permian Basin, and West Texas from the first round of precipitation earlier this evening. This upcoming round will be the ‘big show’ we’ve been anticipating and will likely cause dangerous travel conditions with extremely hazardous roads. I’ll have another update out at 2 AM or sooner if conditions warrant.
