A brief episode of light winter weather is possible this evening across parts of North Texas. At this time the highest potential for freezing drizzle or very light freezing rain looks to remain just north of the immediate D/FW Metroplex. However, the freezing line will be precariously close. A glaze of ice is possible beginning late this afternoon through late tonight north of a Weatherford to Bonham line. We do note that this does include Parker, Wise, Denton, and Collin counties. Those in the northern ‘burbs’ of the metroplex may see a glaze of ice form on elevated surfaces. Primary surface roads should not be impacted, but icy spots may develop on bridges, overpasses, and lesser-used secondary roads. Temperatures will not rise above freezing until late Wednesday morning. Any travel issues that develop today may continue through the Wednesday morning commute. This is not expected to be a high-impact winter weather event, but it only takes a trace of ice to turn a bridge into a skating rink.
