New DISCUSSION, MARINE, AVIATION

DISCUSSION
Issued at 235 PM EDT Fri Apr 26 2024 Upper-air composite analysis highlights a relatively amplified pattern for the CONUS. An upper-level ridge extending from the Gulf of Mexico northward towards the Great Lakes is evident. This stagnant feature is sandwiched between an upper-level trough in the western North Atlantic and another, quite deep trough over the Midwest, which has produced several days worth of severe weather in that region. Closer to home, the aforementioned ridge continues to deflect any organized shower activity. At the surface, high pressure continues to strengthen over the Northeast as it slowly slides offshore into the western North Atlantic. KBYX is echo free of all meteorological returns, and visible satellite imagery is detecting partly cloudy skies across the Florida Keys as well as the adjacent nearshore and offshore coastal waters.
Temperatures are generally in the lower to mid 80s at the island communities.

The aforementioned high will be the main weather story for the next seven days. This high will dive southeastward over the next couple of days, before becoming quasistationary south of Bermuda.
This will result in an extended period of breezy to windy conditions for the Florida Keys. Rain chances will be dictated by any moisture undulations propagating through the Florida Keys coastal waters from the east. One of these moisture surges appears to come through Sunday night, when we elected to nudge PoPs slightly upward. In this stagnant pattern of freshened easterlies and given we are quickly approaching May, it is hard to take at least slight measurable rain chances out of the forecast for any period, and thus dime PoPs are posted for all other periods after Saturday. Temperatures will remain at or near normal, with highs in the lower to mid 80s, and lows in the mid 70s. The breezy to windy conditions coupled with dew points below 70F for the next seven days will keep it quite comfortable for this time of year in South Florida-enjoy it while it lasts.

MARINE
Issued at 235 PM EDT Fri Apr 26 2024 A Small Craft Advisory is in effect for all Florida Keys marine zones, as winds increase to near 20 knots this evening. From synopsis, high pressure centered over New England will dive southeastward in the western North Atlantic through the weekend.
Easterly breezes will continue to freshen this evening, with strong breezes expected through at least Sunday. As the high weakens somewhat south of Bermuda early next week, breezes will modestly slacken, although occasionally fresh breezes will continue through at least Wednesday.

AVIATION
(15Z TAFS)
Issued at 235 PM EDT Fri Apr 26 2024 VFR conditions are expected to prevail through the TAF period. Near surface winds are expected to remain sustained between 12 to 16 knots out of the east with occasional gusts to around 25 knots.

CLIMATE
On this day on Keys Weather History, the daily record warm low temperature of 81F was recorded in Key West. This is also tied for the warmest low temperature ever recorded in April. Temperature records for Key West date back to 1873.
