KEY MESSAGES

Updated at 1052 PM CST Sun Feb 8 2026

- Very low chances (less than 10%) of rain Tuesday.

- Above normal high temperatures into the upper 80s this week.

DISCUSSION

Issued at 1052 PM CST Sun Feb 8 2026

An upper-level ridge looks to remain situated over the Central US through the week, promoting generally warm and dry weather across Deep South Texas. A shortwave looks to traverse across Texas Tuesday night into Wednesday, enhancing pressure gradients along the Lower Texas Coast and bringing a low (20%) chance of rain to portions of the coastal Gulf waters.

High temperatures look to largely remain in the 80s through the week, though western portions of the CWA may climb into the low 90s through the later half of the week. Despite persistent southeasterly winds continuing through the week, a relatively dry air mass looks to remain in place across the area, with dewpoints remaining in the 50s to low 60s through much of the week. This will likely support a wide diurnal temperature range, with low temperatures falling to the upper 50s to low 60s each night.

AVIATION

(06Z TAFS) Issued at 1052 PM CST Sun Feb 8 2026

MVFR ceilings will likely develop at BRO and HRL overnight before lifting and breaking shortly after sunrise. VFR conditions are forecast to continue through the remainder of the period. Winds will likely become light and variable tonight before picking up out of the southeast to south by mid-morning. The latest forecast guidance continues to keep visibilities at VFR levels overnight, with probabilistic guidance still only showing around a 25% probability for MVFR visibilities overnight.

MARINE

Issued at 1052 PM CST Sun Feb 8 2026

Generally favorable marine conditions are forecast to persist through the majority of the period. An upper-level shortwave trough will likely enhance pressure gradients along the Lower Texas Coast Tuesday night into Wednesday, leading to stronger winds along the Laguna Madre and portions of the Gulf waters. Brief Small Craft Should Exercise Caution headlines may be needed Tuesday. Otherwise, light to moderate southeasterly winds and slight to moderates seas are forecast through the week.
