DISCUSSION

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.
