.DISCUSSION...
Issued at 1137 PM CDT Sat Oct 17 2026

Inland winds have finally relaxed behind the front to be out of the 
N around 5-10 mph. As is typical for the first significant cold 
front of the season, our marine regions aren't out of the woods 
quite yet. Winds remain elevated over our waters tonight requiring a 
Small Craft Advisory until 1 AM then transitioning to Small Craft 
Exercise Caution until 7 PM Sunday. Likewise, a High Rip Current 
Risk is in effect until Sunday morning. By the afternoon, wind 
concerns are mostly dissipated region-wide, with light NE winds 
turning easterly during the day on Sunday. Temperatures are in the
low-mid 70s with lows in the upper 40s for our northernmost 
counties and lower 60s along the coast. Overall, we'll wrap up our
weekend cool, dry, and mostly sunny.

As high pressure continues settling in to the NE and flow becomes 
largely out of the east, temperatures will slowly climb throughout 
the workweek. By Thursday, highs will be in the upper 80s with 
patches of us in the low 90s. On the bright side, these will be 
mostly dry highs, with dew points staying at and below 65. Speaking 
of moisture, rain chances are also low throughout the week as our 
typical Gulf moisture is pushed mostly to our west, keeping PWATs 
between 0.5-1". Tuesday sees a surface trough develop along our 
coast, bringing the biggest chance of rain for the week, though 
the primary rainfall will be over the waters. By and large, expect
a dry, calm, mostly sunny week with temperatures slowly climbing 
in the absence of rain and northerly winds.
