Area Forecast Discussion National Weather Service Key West FL 412 AM EDT Thu Jul 9 2020

DISCUSSION. CURRENTLY. Under partly cloudy skies and light north to northeast winds, temperatures are in the lower to mid 80s in most island communities. Meanwhile, local radars are detecting isolated showers and an occasional thunderstorm near the Florida Keys and the adjacent nearshore waters. On our marine district, winds are mainly north to northeast at less than 10 knots.

SHORT TERM. (Today through Saturday night) Our region will lie between a splintered ridge axis, with one center over the Gulf of Mexico and the second just to our east for at least the next couple of days. With that, ample low level moisture and a light north to northeast steering flow will provide the possibility of cloud line genesis today and cells and outflow boundaries triggering off the South Florida Mainland over the next couple of days. Hence, isolated 20 percent rain chances will be retained. For the beginning of this weekend, the latest GFS guidance run indicates a secondary short wave trough will dig further equatorward than previous runs, while ECMWF remains steadfast with the ridge axis lingering near the Florida Keys and the Straits of Florida. For now, enough low level moisture and a light south to southwest wind may allow cloud line genesis or the cuban shadow which would limit cell coverage. Subsequently, will keep isolated 20 percent rain chances for this time frame.

LONG TERM. (Sunday through Wednesday) As mentioned earlier, GFS holds our region in the southern envelope of a low and mid level trough, but due to consistency and climatology will lean toward the ECMWF solution which keeps our region within a col region to weak anticyclonic flow from (700 mb- surface) through most of the period. However, given some uncertainty will retain 20 to 30 percent rain chances until forecast confidence and consistency comes about.

MARINE. Away from showers and thunderstorms, light to gentle winds will prevail on Keys coastal waters for the balance of this week before gentle winds predominate for most of our marine district this weekend.

AVIATION. VFR conditions will be the predominant for today. With that being said, there isolated showers and possibly a thunderstorm or two will remain in the vicinity of both terminals this morning. Thereafter, we will see a break with additional showers re-developing this afternoon. Winds will remain light through the period.

CLIMATE. In 2005, Hurricane Dennis significantly impacted the Florida Keys. It produced a cool high temperature of 82 degrees and 4.25 inches of rain fell at Key West airport, both daily records. This is the only Hurricane to directly affect the Keys during the month of July in the last hundred years.
