Area Forecast Discussion National Weather Service Key West FL 507 AM EDT Wed Apr 21 2021
DISCUSSION. CURRENTLY. Under mostly cloudy skies and southwest winds of 5 to 10 mph, temperatures are in the upper 70s along the Island Chain. Meanwhile, local radars are not detecting any significant precipitation echoes in our area. On our marine district, winds southwest to west varying from 2 knots at Smith Shoal Light to 12 knots to Carysfort Reef Light.
SHORT TERM. (Today through Friday night) A surface trough in the extreme Southeast Gulf of Mexico early this morning, will limp through the Florida Keys by late this afternoon. Meanwhile, a mid and upper level pertubation will lag well behind the surface boundary, before passing through our entire region late tonight. So despite plenty of moisture, subtle low level convergence with an absence of large scale ascent. With that, expect a swath of showers and a few thunderstorms will migrate southeastward, but decay as it approaches the Island Chain. Hence, only low chance pops will be kept beginning this afternoon, with only isolated pops due to dry air filtering into our area tonight through the rest of this week. Outside of slightly cooler and drier air with high temperatures in the lower 80s on Thursday, temperatures will be about 5 degrees above normal otherwise.
LONG TERM. (Saturday through Tuesday) A large and expansive region of high pressure centered over the Western Atlantic Ocean with a ridge axis extending across the Sunshine State on Saturday will settle equatorward to near our region Saturday night, before retreating eastward as a trough dissipates in South Florida Sunday. Thereafter, another large and sprawling area of high pressure over the Eastern United States will press southward into the Sunshine State and the adjacent Atlantic and Gulf waters. Given large scale anticylonic flow, moisture will predominately be found below 850 mb with no mid and upper level disturbances anticipated. With that, only isolated 10 to 20 pops will be carried. Otherwise, temperatures will remain above normal.
MARINE. Light to gentle southwest winds will clock around to northwest by this evening, before moderate north winds overspread our marine district overnight. Moderate north to northeast winds will turn northeast and slacken into the light range Thursday afternoon. Beyond that, northeast to east winds will freshen late thursday night, with fresh winds expected on Friday and Friday night. For this weekend, moderate southeast winds will abate by Friday.
AVIATION. MVFR ceilings may prevail early this morning at EYW, otherwise VFR is expected to prevail at both EYW and MTH today. Showers and a few thunderstorms are expected to develop mainly west and north of the island chain, but possibly encroach on the terminals this afternoon. Vicinity showers are currently indicated this afternoon. Winds will oscillate from near calm to south to southwest mainly less than 10 knots early this morning, then become west and eventually northwest 8 to 12 knots throughout the day and into the evening.
CLIMATE. In 1987, the daily record low temperature of 63 degrees was recorded in Key West. Temperature records date back to 1872.
