Area Forecast Discussion National Weather Service Key West FL 1036 PM EST Tue Jan 28 2020

DISCUSSION. A weak pressure pattern prevails over the Keys this evening. Light to gentle breezes will continue through the day on Wednesday, though winds will become southerly late Wednesday in advance of the next cold front. This cold front is currently sharp and progressive as it currently trails from from far eastern Texas into the western Gulf. It will cross the eastern Gulf starting late Wednesday and Wednesday night. The front will be weakening by the time it crosses the island chain late Wednesday night.

Nonetheless, as the front crosses the warm waters of the Gulf Loop Current off to our west, showers and thunderstorms should ignite out there. Mid- and upper-level clouds will stream off to the east and bring increasing clouds to the Keys late in the day.

On Wednesday night, a few weakening showers should make it to the Keys, though thunder will likely disappear as the front moves east of the Loop Current. Overall, this front will be weak by the time it reaches the Keys.

MARINE. A generally weak pressure pattern will prevail into Wednesday. A weakening cold front will limp through the Keys waters on Wednesday night and early Thursday. High pressure will nose in from the north later Thursday through early Friday. The next cold front will likely arrive around Saturday.

AVIATION. Light and sometimes variable winds through mid-day Wednesday could lead to a number of traffic flow reversals at the EYW and MTH terminals. Otherwise, FEW-SCT coverage of cumulus and strato- cumulus with bases in the 025-035 range will prevail.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerous of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
