DISCUSSION
Issued at 425 AM EDT Fri Apr 19 2024

Mostly clear, mild and dry conditions prevail along the Florida Keys on this early Friday morning, with radars detecting no precipitation across the region. Temperatures are hovering in the mid 70s, with dewpoints in the upper 60s to near 70, and winds on land from the east to southeast at 10 to 15 mph. Surface analysis depicts high pressure over the western Atlantic, extending westward across the Florida peninsula into the eastern Gulf of Mexico. Aloft, deep ridging remains in place over the Gulf, and continues to dominate the weather regime across South Florida and the Keys. The 00Z Key West sounding found a typical profile for April, with a strong inversion based near 3700 feet, PW of 1.22 inches, and very dry mid levels above the inversion. More recent MIMIC-TPW satellite imagery shows similar estimated PWs across our region, with higher PWs confined far to our south over the Caribbean Sea.

Typical late dry season weather will prevail today and through the weekend, as the lower to mid level ridge over the Gulf remains in control. Expect mostly clear and dry conditions to continue, with temps running a degree or two above normal (highs in the mid 80s and lows in the mid 70s). Dewpoints will hold in the upper 60s to near 70, so we will continue to avoid the onset of summertime humidity just yet.

A shortwave trough moving across the Southeastern states will flatten the ridge Sunday through Monday, with a very weak surface front dissipating over South Florida by late Monday. This should have very little effect on our sensible weather, with breezes briefly shifting to the north Monday night, and temps/dewpoints perhaps dropping a couple of degrees. At this time, it appears that any associated shower activity will probably remain north of our area through Monday night, and have continued with a dry forecast through those time periods.

Heading further into next week, a more zonal flow pattern over the Gulf and Florida should allow for a weaker/higher subsidence inversion, with just enough moisture present to perhaps generate isolated showers at times. We will keep an eye on a mid-level disturbance forecast to move quickly across the eastern Gulf on Tuesday, as such features in April can sometimes bring a MCS near or into our area. For now, have continued with just a slight chance of showers from Tuesday onward. Temps will remain near normal, with highs in the mid 80s and lows in the mid 70s.

MARINE
Issued at 425 AM EDT Fri Apr 19 2024

Overnight observations show E/SE breezes of 10 to 14 knots along the reef and at Long Key C-MAN, with seas at Satan Shoal running between 2.5 and 3 feet. No marine headlines are currently in effect, and none are expected through the weekend. From the synopsis, high pressure over the western Atlantic will maintain gentle to occasionally moderate east to southeast breezes across the Keys coastal waters through the weekend. Gentle southerly breezes on Monday will become northerly Monday night as a weak front dissipates over South Florida.

AVIATION
(06Z TAFS)
Issued at 425 AM EDT Fri Apr 19 2024
