San Antonio First Warning Weather Forecasts Mild December WeatherWe will see more clouds move into the region over the next twenty four hours. The driving force will be an upper level system off the western U.S. coast. The upper low is headed our way starting to pump Pacific moisture back into the region. Rain chances will begin to increase late tonight into Friday morning with the approach of the upper low. Thursday will see a mixture of clouds with temperatures just slightly cooler, in the mid to low 50s. The upper level low will push across the Central Plains Friday into Saturday and will push a weak cold front into the area come Saturday morning. This will set the stage for some showers Friday afternoon and evening. The rain moves out quickly late Friday and we will drop into a dry, warmer weather pattern as we head into the new week. Temperatures should rebound into the upper 60s by mid-week. Join Shaun Stevens this morning on Fox News First. He'll let you know when to expect the next cold front in your area.
