New DISCUSSION, MARINE, AVIATION
DISCUSSION
Issued at 230 PM EST Sun Jan 12 2025 Visible and water vapor imagery highlights broad, anticyclonic flow over the Florida Peninsula, with a longwave trough buckling over the Gulf States.
The Florida Keys remain engulfed in a low, albeit decaying stratus cloud deck. Owed to the ample cloud cover, along with the north to northeasterly surface flow off the cool waters north of the Island Chain, temperatures remain in the mid to upper 60s at this early afternoon hour, several degrees below all available deterministic numerical weather prediction guidance would suggest.
The CONUS will remain in a relatively amplified pattern for the next seven days, resulting in yet another frontal passage through the Florida Keys this week. This front will bleed through the Keys Tuesday night, as a shortwave trough pivots from the Upper Midwest southeastward to the Mid-Atlantic. Forecast soundings suggest contrary to several of the past fronts, tropospheric moisture will linger in the wake of the front. Coupled with the moderate to fresh northeasterly flow and associated moisture fluxes, have elected to up measurable rain chances to around 20% for Tuesday night through Thursday.
Moderating temperatures are expected late in the week and into the weekend, as high pressure progresses from the Southeast into the western North Atlantic. Above normal temperatures coupled with near-nil rain chances are expected for this period, before another cold front possibly approaches the Florida Peninsula by the end of next weekend.
MARINE
Issued at 230 PM EST Sun Jan 12 2025 Although breezes have temporarily slackened in the eastern marine zones owed to the heating of the South Florida Mainland, breezes are expected to freshen once again after sunset. From synopsis, light to gentle northeasterly breezes will continue through Monday, gradually veering to the east to southeast by Tuesday.
Another cold front is progged to push through the Keys marine zones Tuesday afternoon and evening, with a northerly wind surge expected in its wake. Small Craft Advisory conditions will be possible for portions of the Florida Keys coastal waters as early as Tuesday night, possibly continuing through at least Wednesday night.
AVIATION
(18Z TAFS)
Issued at 230 PM EST Sun Jan 12 2025 VFR conditions are mostly expected to persist through the evening and overnight hours.
Visible satellite imagery continues to show a persistent stratus deck across the Keys. For the most part it looks like the cloud deck is between 3100-3400 ft AGL, though, KMTH has been overcast at ~2500 ft for the last several hours keeping them MVFR. Current thinking is the cloud deck will remain through late afternoon perhaps even early evening before some breaks/clearing is anticipated to occur. Near surface winds are expected to remain northeasterly through around midnight before shifting to the east and then to the east to southeast Monday morning.
CLIMATE
On this day in Keys Weather History, the temperature dropped to 41F in Key West set back in 1886, which is the daily record and tied for the coldest temperature recorded in Key West. Temperature records date back to 1873.
