The cold front will continue to linger across the Rio Grande Valley for the majority of the night before advancing southward with a secondary push into early Thursday morning from a high pressure system to the north. A chance for showers and areas of fog will be expected after midnight across Deep South Texas. Behind the front, expect much colder air to filter across the region on Thursday. For the mariners, expect light winds and conditions early before winds increase and seas build late and into the day on Thursday.
Big changes in store for the Rio Grande Valley and Deep South Texas in the wake of the cold front advancing across the Rio Grande Valley throughout the night. Expect overcast skies with light rain or drizzle, breezy conditions and much colder air with temperatures falling throughout Thursday and into Thursday night. The early morning low temperatures on Friday will fall into the middle 30s across the Ranchlands and the low 40s across the Lower Rio Grande Valley. Mariners expect rough conditions on all coastal and Gulf waters with windy conditions and elevated seas. A Gale Warning is in effect for Thursday into the Early Morning Friday for the potential of frequent gale force wind gusts.
A wind advisory is in effect for Thursday along the coast with the building of a strong high pressure system into South Texas in the wake of a cold front. Sustained winds of 20 to 30 mph will be expected with frequent gusts of 30 to 40 mph. It is a good idea to move any unsecured light to moderate weight items…such as patio furniture and/or empty trash cans. Driving will be difficult for high profile and light weight vehicles.
Strong north winds rapidly increase with gale conditions developing Thursday morning into Thursday afternoon as high pressure builds into the region behind a cold front. Sustained winds of 25 to 30 knots will be expected with frequent gusts of 35 to 40 knots. Seas across the gulf waters will build steadily exceeding 10 feet shortly before Noon approaching 14 feet during the afternoon. Hazardous marine conditions to persist through Thursday evening.
Rain chances will increase on Thursday with strong northeasterly winds gusting up to 35 mph. Temperatures will hold nearly steady or fall during the day as polar high pressure begins to build in, allowing low temperatures Friday morning to drop into the 30s for many areas with wind chills even lower; so prepare your heavier jackets before heading to work or school on Friday. Conditions will improve towards the end of the weekend with temperatures warming back up in the 70s and low 80s prior to another cold front which will cool things back towards normal for the start of next week.
