FORT WORTH — Thick fog blanketed North Texas Thursday as rain chances increased thanks to a storm system from the Pacific Northwest that arrived Wednesday.Dense fog caused by a warm front prompted forecasters to extend a dense fog advisory for North and Central Texas until 6 a.m. Friday. Many areas will experience visibilities down to near zero at times.Zero visibility was being reported at the Dallas/Fort Worth Airport during the noon hour, according to weather reports. At 9 a.m., Cleburne also reported zero visibility and it remains low during the lunch hour, according to forecasters.The dense fog was expected to dissipate as the day wore on, according to the advisory.“But there’s a chance we could see it later tonight,” said meteorologist Joe Harris at the National Weather Service office in Fort Worth. “It’s widespread right now, but we do have a few counties where it’s getting better.”Tonight’s forecast calls for cloudy skies with a 50 percent chance of showers and isolated thunderstorms with a high of 54.Friday is likely to bring heavier rain and a high of 63. Forecasters are predicting rain chances of 80 percent on Friday.The Arctic front that has many Northern and Eastern states locked in a deep freeze has moved out of North Texas. “We are often on the very southern edge of the Arctic fronts,” meteorologist Dan Shoemaker said Wednesday. “But this one stuck around for a while.”Once the rain leaves North Texas, forecasters say, the weekend should be sunny and mild. Saturday and Sunday morning temperatures will be in the upper 30s to low 40s, with daytime temperatures in the 60s.January in North Texas is often dramatic weather-wise, Shoemaker added. Record highs have reached the 80s with lows sinking to the single digits.“January is a month of swings,” he said. Staff writer Domingo Ramirez Jr. contributed to this report.
