Area Forecast Discussion National Weather Service Key West FL 443 AM EDT Fri Jul 3 2020

DISCUSSION. Weather conditions are warm and dry across the island chain early this morning with a light southeast to south breeze. Temperatures are hanging onto the mid 80s in exposed locations with the typical 'cool' spot at Big Pine Key radiating into the mid 70s. A zone of weak surface convergence has developed across the Gulf waters north of the Keys, evident from a blossoming line of showers and thunderstorms on radar and satellite imagery. This area of convergence is slowly drifting northward along the weak low-level southerly flow, which the latest runs of the HRRR capture quite well (despite never developing precipitation within this area). Only a few isolated showers dot the remaining distant coastal waters of the Straits.

Concerning the forecast through Sunday night, a slightly wetter pattern is expected to develop as low to mid-level winds shift gradually southwest to west in response to a sagging ridge axis. This should allow for better (reverse) cloud line development beginning tomorrow and continuing into Sunday. MOS and blend guidance have been persistent in advertising chance PoPs on Sunday, which makes sense given a TUTT cell is progged to pivot overhead and increase total column moisture and shear marginally. Otherwise typical summer mugginess and warmth will continue with highs in the lower 90s and overnight lows near 80.

Next week deep layer ridging will return with a more seasonable easterly vertical wind profile setting up by Tuesday. PoPs will go back to being purely surface driven with a rather hostile temperature and moisture profile from 850-700mb due to the ridging. Climatological 20 PoPs are appropriate given the overall synoptic pattern and competing meteorological factors. Summertime heat and humidity continue with no tropical threats on the horizon.

MARINE. Light to gentle breezes are expected to prevail through the holiday weekend, mainly from the south to southwest as a subtle ridge axis settles over the Straits of Florida. By Sunday night the ridge axis will begin to amplify and expand northward over South Florida, backing winds southeasterly Sunday night and then easterly by Monday afternoon. Gentle to moderate easterly breezes are expected to prevail for the bulk of next week.

AVIATION. VFR and light breezes will prevail at the EYW and MTH terminals through the afternoon. Forecast soundings for this afternoon indicate a slight chance for thunderstorm development along and in the lee of the Lower Keys, extending ENE into the coastal waters north of Vaca Key. Based on this scenario, we have included VCTS for MTH this afternoon.

CLIMATE. On this date in 1989, the daily record cold high temperature of 83 degrees was last recorded in Key West. Temperature records date back to 1872.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
