An extreme cold watch is in effect for much of Central Texas Wednesday and into Thursday morning, with windchills between 0 and 10 degrees. Why it matters: This winter has been a roller-coaster, with freezing temps followed by a too-early warm spell.

Wednesday morning will be bitterly cold and blustery, temperatures in the 20s to the northern counties and 30s elsewhere in Southeast Texas. High temperatures will only warm to the low 40s, with cloudy skies clearing out through the evening hours on Wednesday.
