GMZ005 Synopsis For Keys Coastal Waters From Ocean Reef To Dry Tortugas 421 Am Edt Wed Apr 24 2024
Synopsis - Gentle to moderate breezes will prevail over the next couple of days as high pressure moves from the southeastern states offshore into the western atlantic. This high will be subsumed into a larger high spreading into the western north atlantic late this week and into the weekend. This will be accompanied by freshening easterly breezes across the keys waters.
the approximate shoreward edge of the gulf stream is currently unavailable.

DISCUSSION
Issued at 400 AM EDT Wed Apr 24 2024

Currently - Seasonably mild conditions prevail across the Keys this morning in wake of the recent very late season backdoor cold front. Temperatures are in the mid 70s with dew points down in the mid 60s. High pressure spreading eastward off the southeast Atlantic coast is responsible for gentle to moderate easterly breezes across the area. Broad troughing prevails from the mid level up, but is disconnected from the surface by a healthy subsidence inversion based near 850 mb. This is high enough for weak shower formation. However, all shower activity has been relegated to the warmer distant Florida Straits.

Forecast - The surface high to our north will continue to elongate into the Atlantic while shifting southward slightly. This will result in winds modestly relaxing. Meanwhile large scale troughing will remain aloft, but continue to not play a factor in local weather due to a lack of moisture and lingering inhibition. Expect near normal temperatures, but dew points will remain in the mid 60s.

Heading into this weekend, a larger more powerful high will drive southeastward off the northeast into the Atlantic and absorb the old ridge. This will act to sharply steepen the local pressure gradient and drive up winds. In addition, the northeasterly trajectory of the incoming air will likely result in dew points falling a few degrees in to the lower 60s to near 60. Meanwhile, troughing aloft will give way to a rather amplified ridge migrating eastwards across the gulf. The combination of all of the above will result in a continuation of our essentially rain free pattern.

For late this weekend in to early next week, the previously mentioned high will steadily shift southwestward along the coast.
On balance, local winds will remain fresh to strong. However, the lengthening residence time of incoming air over relatively warmer waters will result in slowly climbing dew points. Expect dew points to approach 70 early next week. The increase in lower level moisture and weakening mid level ridging and inhibition may spell the end of our dry stretch. Will maintain slight chance beginning in the Monday time frame.

MARINE
Issued at 400 AM EDT Wed Apr 24 2024

A modest ridge over the southeast will lengthen further out into the Atlantic while shifting slightly south. This will reuslt in winds relaxing a bit further in the near term. This ridge will be absorbed by a sprawling high driving southeastward off the northeast Atlantic Coast and result in sharply stronger breezes late this week and into this weekend. It appears Small Craft Advisories may be reuqired beginning around this time.

AVIATION
(06Z TAFS)

VFR and dry conditions will prevail at both EYW and MTH through the TAF period. Near surface winds will be easterly at near 10 knots.
