A DENSE FOG ADVISORY is in effect for areas south of the I-20 corridor through 11 am Tuesday. Light winds and moisture rich low levels will lead to areas of dense fog development through daybreak and after this morning. Visibility may be reduced to less than 1/2 mile in spots through the morning hours. The dense fog may only last 1 to 2 hours, but be prepared to allow extra time to reach your destination this morning. Use low beams and drive cautiously while commuting this morning.
An arctic front will slice through the region Wednesday evening. This will send temperatures tumbling in the 20s and 30s by Thursday morning, but the coldest air will descend into North and Central Texas Thursday night into Friday morning. Temperatures in the teens and 20s are expected. Wind chills--or what it feels like to exposed skin--will be in the teens and 20s both nights.
With the expected arctic air intrusion Wednesday night through Friday, remember to keep the 4 P's in mind for protection against the frigid temperatures expected. Protect pipes, faucets, and sensitive plants, as well as preparing outdoor pets and people without ample heating for the impending chilly weather ahead.
Warmer temperatures will return by the weekend, as southerly breezes return. Afternoon highs will not be too far off normal values for this time of the year. Enough moisture will exist across eastern North Texas for low chances of showers and thunderstorms Saturday night and Sunday, as an upper disturbance moves across the area. Rainfall will be light.
