The main forecast update for this evening has been to reflect the faster movement of the cold front, which is at a College Station/Crockett line as of 10 PM CST. Colder temperatures will begin to move into the area after 10 PM CST, with a mix of rain/freezing rain/sleet beginning north of a Brenham to Trinity line sometime between 12 AM and 3 AM.
Light to moderate rain with and behind the front will gradually transition to this wintry mix, with this mix spreading into the Houston metro after sunrise and reaching the coast after noon. Intermittent periods of winter weather will continue throughout the day, ending during the evening hours on Tuesday.
Ice accumulations north of Interstate 10 may range from 0.05-0.1" and south of Interstate 10 may be as high as 0.05". Snow accumulations may be up to 0.5" north of Interstate 10, with now accumulations over one inch possible north of a Brenham to Livingston line.
North winds will be breezy behind the front (10-20 MPH with stronger gusts up to 30 MPH possible). This will result in wind chills falling into the single digits and teens Tuesday morning in the Winter Storm Warning area. Additionally, should ice begin to accumulate, there may be issues with power lines at these speeds.
Note: There is the potential for bands of heavier precipitation to develop during the day tomorrow; within those bands locally higher ice or snow amounts will be possible. The farther north a band develops, the greater the potential for higher snow totals than forecast. The farther south, the greater the potential for higher ice totals than forecast.
