Chilly night on tap with isolated showers in the ranchlands late. A cold front will work into the region tomorrow, bringing big changes. A Gale Warning has been issued for all coastal waters from 9am Tuesday morning until Midnight Tuesday night. Conditions are expected to deteriorate rapidly tomorrow. Be safe!
Maps are getting colorful and we're running out of room, so here's a list of the inland warnings and advisories starting Tuesday morning and continuing into Wednesday. Bottom line, there's a strong cold front bringing arctic air down to the surface as far south as Brownsville. Conditions will be dangerous for anyone or anything left exposed. From people to pets, plants to pipes, make sure everything is secured, warmed, sheltered and prepared for the next few nights. Stay safe, stay warm!
Hazardous marine conditions will develop behind a cold front Tuesday morning and continue into Tuesday night across nearshore and offshore Gulf waters. A Gale Warning is in effect for frequent wind gusts above 34 knots on all lower Texas coastal waters.
An arctic cold front will lead to major changes for the beginning of the 5 day period. Tuesday will feature crashing temperatures throughout the day with a possibility for a wintry mix consisting of rain, freezing rain and sleet over portions of deep south Texas from the afternoon into Tuesday night. Rain and freezing rain will linger into Wednesday where temperatures are expected to only reach the middle 30s to near 40 degrees. The wind chill values or "feels like" temperatures will trend in the teens and 20s from Tuesday afternoon through Thursday morning. Cloudy skies and drizzle will linger into Thursday with a possible secondary freeze across northern portions of the region during Thursday morning. Expect sunshine to return Friday into the weekend with warmer temperatures. When the weather gets this cold, life and property are at stake. Stay safe and warm!
