DISCUSSION
Issued at 1018 PM EDT Thu Mar 28 2024
Windy conditions are ongoing across the Florida Keys and surrounding coastal waters. Marine observation platforms are measuring winds of 20 to 25 knots along the Reef, with gusts nearing 30 knots. A cold front moved through earlier this afternoon and high pressure has begun to build in behind it, causing a tightened gradient across the region. While KBYX is not detecting any meteorological echoes across the forecast area, well defined sea spray is very visible north of the island chain thanks to the strong northwest to north winds creating large seas in the Gulf waters. Tonight's sounding sampled a very dry atmospheric profile, boasting a PW of 0.65 inches which is well below the 10th percentile for this day. Temperatures have been slowly going down over the course of the past few hours, with a current reading of 71 degrees at the NWS office in Key West. Dew points have also plummeted, now ranging from the upper 50s to the lower 60s.
A surface low off the Carolinas, associated with the cold front that moved through earlier, will zip northeastward further into the North Atlantic while the high pressure over the Southeast treks slightly more eastward. As these two pressure systems move in their respective directions, the gradient will begin to relax, allowing winds to gradually decrease overnight while still remaining elevated. With a drier airmass currently in place, no shower developme911nt is expected, so have kept rain chances near nil. The forecast is on track and no changes were necessary.
