The National Weather Service has issued a Dense Fog Advisory for Bell County and Central Texas until 8am Tuesday. 

The chance for fog is pretty wide spread overnight at can limit visibility to a  quarter mile or less at times. If you're traveling late this evening please drive carefully. Most of the I-35 and I-45 corridors in central Texas will be affected, as well as Interstate 20.

Limited visibility early Tuesday may result in some slow downs and trouble spots, and may result in hazardous driving conditions. A Dense Fog Advisory means visibility will be reduced to less than one quarter mile. Leave extra distance when following in traffic and remember to use your low-beam headlights if you need to.

The cold front that is expected in central Texas seems to be moving faster than expected. KWTX now reports the coldest air will impact central Texas on Wednesday evening. Temperatures Thursday and Friday morning could dip below freezing. Low's the 20's are even possible in some areas.
