Area Forecast Discussion National Weather Service Key West FL 1024 AM EDT Fri Aug 7 2020

DISCUSSION. Currently - A a ridge extends across the Florida Peninsula, resulting in light to gentle easterly breezes across the area. Lower to mid level ridging is in place aloft. This mornings sounding indicated normal PWAT, ample CAPE, and only a sliver of inhibition. Latest radar indicates isolated to widely scattered showers across the forecast area and a few island locations being affected.

Short Term Update - The surface ridge will remain across Florida this afternoon, although it will be briefly split by day time heating. Across our area, winds will remain light to gentle out of the east. Guidance suggests the lower level steering flow will back north of east this afternoon. As a result, despite overall convective activity diminishing, conditions are expected to become more conducive for island cloud line formation. Will maintain low chance precipitation with day time highs near 90.

MARINE. Ridging across Florida will maintain light to gentle east breezes across Keys waters. Day time heating over florida will result in winds slackening and become more varying in direction over our deep gulf waters.

AVIATION. VFR conditions will prevail at both EYW and MTH today. There is a chance for a cloud line to develop early afternoon due to the weak easterly flow and daytime heating. Models are showing that showers and thunderstorms could move off the mainland of Florida later this afternoon as well. Should either happen and pass over an airport, expect VCSH and/or amendments to be added to the TAFs with TEMPO MVFR conditions and wind gusts to near 20 knots.

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.
