From Meteorologist Clemente Morales:

Today’s warm weather will be a memory of the past tomorrow as very cold air filters into the Big Country bringing frigid wind chills to the area. Stay warm as we head into tomorrow. For today, we will see mostly cloudy skies and a high of only 50 degrees. The winds will be breezy at 5-15 mph through the afternoon.  For this evening, mostly clear skies is what we can expect with the low right around 10 degrees. The winds will be strong at 25-30 mph out of the north.
