DISCUSSION
Issued at 242 PM EDT Tue Apr 23 2024

The Florida Keys have enjoyed a rather pleasant late April day in the wake of yesterday's frontal passage. Sprawling high pressure located along the Eastern Seaboard is maintaining breezy northeast winds across the island chain. Temperatures have risen into the lower 80s with dew points ranging from 65 to near 70 degrees. Dry air has kept showers well away from the Keys with even a very brief thunderstorm occurring over the distant Straits of Florida.
Otherwise, the inversion noted on this morning's sounding can be seen on visible satellite imagery. This has produced ripples in the low level cloud field as rising air hits the staunch inversion and undulates downstream.

The forecast has not changed all that much. A mid level disturbance currently across the central Gulf of Mexico will slide southeast tonight but should stay just west of the Lower Keys to really affect us. Otherwise, low level ridge will settle across the western North Atlantic and remain a nearly permanent feature through the next 7 days. This will keep our winds generally east or slightly north of east through the same period. At the same time, upper level ridging will begin nosing in from the west, eventually phasing with the low level ridge towards the end of the week. This will do one of two things. The first is the easterly winds will strengthen beginning Thursday night and reaching peak strength Saturday night through Sunday night. The second will be a gradual increase in the boundary layer. This will nudge PoPs up to slight category (10 percent), mainly Saturday and beyond. Otherwise, no real features to discuss and temperatures will be almost identical from day to day with day time highs in the lower to mid 80s with overnight lows in the mid 70s.

MARINE
Issued at 242 PM EDT Tue Apr 23 2024

Small Craft Should Continue to Exercise Caution until winds and seas subside. Moderate to fresh northeast to east breezes will slacken to gentle to moderate overnight through Thursday across the Keys coastal waters, as high pressure moves from the Southeastern states offshore into the western Atlantic. A stronger high will move into the western North Atlantic late this week and into the weekend, producing strong easterly breezes across the Keys waters.

AVIATION
(18Z TAFS)
Issued at 242 PM EDT Tue Apr 23 2024

VFR conditions will prevail at EYW and MTH today; however, brief periods of MVFR CIGs are possible in the late afternoon while a weak cloud line remains over the island terminals. Near-surface winds will remain northeasterly to easterly in the 10 to 15 knot range with gusts slackening by midnight.
