Numerous winter weather hazards continue into tonight with freezing temperatures across all of deep south Texas and freezing rain mixed with sleet expected in the Rio Grande Valley. A glaze of ice is possible and both drivers and pedestrians are advised to proceed with caution this evening into tonight, especially on elevated surfaces such as steps, overpasses and bridges. Hazardous seas are expected across all coastal waters through tonight, with a Gale Warning currently in effect until midnight and Small Craft Advisory conditions expected overnight.
Here is the latest timing estimate for the potential of wintry mix consisting of sleet and freezing rain across deep south Texas for today into Wednesday. Roads will become slippery with any icy conditions and will result in difficult travel conditions, including during rush hour Tuesday evening and Wednesday morning. Slow down and use caution while driving. The latest road conditions for the state can be obtained by calling 511 or visiting drivetexas.org. Outside of the wintry precipitation chances, expect a soggy day with overcast skies and light rain or drizzle.
Update 10 pm: A strong cold front has brought arctic air down through deep south Texas and multiple winter weather hazards are in effect with freezing rain continuing overnight into the lower Rio Grande Valley. 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. Stay safe, stay warm!
Hazardous marine conditions will continue across the Laguna Madre and the lower Texas Gulf waters in wake of this morning’s cold front. A Gale Warning continues until midnight tonight for all lower Texas coastal waters. A Small Craft Advisory is in effect for nearshore and offshore Gulf waters until 6 pm Thursday. A Small Craft Advisory for Winds is in effect for the Laguna Madre until 6 am Wednesday.
Cold, soggy and overcast conditions will continue through the end of the workweek with light rain. Freezing temperatures are expected Wednesday morning and may be possible across the northern ranchlands into early Thursday morning. Wind chills or “"feel's like"” temperatures are expected to be in the 20s through Wednesday into Thursday morning. Additionally, a chance of a freezing rain will be possible Wednesday morning and Wednesday night across the northern ranchlands. Warmer conditions will then return this weekend with partly cloudy skies.
