| Area Forecast Discussion National Weather Service Key West FL 704pm EST Sunday Jan 24 2021 A dry and stable airmass continues to dominate the weather conditions across the Florida Keys. Radar and satellite imagery depict mostly sunny skies across the island chain and surrounding waters with only shallow cumulus clouds over the Straits. Temperatures are in the mid to upper 70s across the island communities. Rain chances remain nearly nonexistent, which is below the climatological value of about 10 percent for January. A weak cold front has reached southern Florida and the northwestern Bahamas, but this system is not expected to be a factor in our weather conditions as it is expected to lift northward over the next couple of days. .FORECAST... An expansive high pressure system currently over North Carolina is expected to move southeastward, enveloping most of the western Atlantic, including the Florida Keys. The presence of this feature will freshen winds across the Straits tomorrow and keep us under a dome of relatively stable weather conditions and rain chances near nil. However, the broad ridge will dissipate on Tuesday and relax its grip on the Florida Keys as a strong low pressure begins to take shape over the southeastern United States. Temperatures across the Keys will continue to increase slowly through Tuesday with highs in the low 80s and lows in the upper 60s to near 70 degrees. Moisture will gradually increase on Wednesday and Thursday ahead of the strong frontal boundary that is expected to sweep across the island chain. Model guidance indicates that the precipitable water will be around 1.40 inches late Wednesday and early Thursday. This is near the 75th percentile for this time of the year. However, there is going to be little to no support in the mid to upper levels of the atmosphere in our area. Thus, rain chances ahead of the front remain near 10 percent. The strong cold front is expected to cross the Keys early Thursday and there is good agreement among the model guidance on the timing and strength. The cold front will be followed by clearing skies and cooler temperatures, with a low near 60 degrees on Friday morning. The strong ridge behind the cold front will also allow for wind gusts near 25 mph across the island communities on Friday morning. Fresh to strong northerly breezes are expected over the coastal waters for Thursday and Friday. Marine There are no watches, warnings, or advisories effect for the coastal waters of the Florida Keys. From synopsis, an expansive high pressure system will move southeastward over the western Atlantic before weakening and dissipating on Tuesday. Southeast breezes will freshen up tomorrow before diminishing on Tuesday. The next feature of interest will be a strong cold front that will cross the Florida Keys early Thursday. Fresh to strong northerly breezes are expected Thursday and Friday. Climate In 2003, Key West experienced a very chilly day behind a powerful cold front, with a high temperature of 56F and a low temperature of 45F, both records for the date. Temperature records date back to 1872. NOAA Key West FL Office: Watches - Warnings - Advisories FL...None. GM...None. |
