Winds will become southwest through the day, with some gusts to 20 knots or so. A few showers will be possible starting this afternoon and continuing into the first part of tonight. Prev discussion issued 515 am edt Wed oct 16 2019 discussion... westerly flow aloft continues across the region between a deepening mid upper-level trough moving across the great lakes and mid upper-level ridge axis stretching west to east across the gulf of mexico south of the peninsula. At the surface, south southeast flow is in place under the influence of weakening high pressure ridging extending over the area from the western atlantic. A quasi-stationary frontal boundary north of the area stretches west from the atlantic across parts of the panhandle into ms la. Flow aloft will gradually strengthen today as the trough passes to the north, while surface flow veers and increases out the southwest south of the frontal boundary. Widespread cloudiness associated with the front will continue to overspread much of the forecast area throughout the day with showers and isolated thunderstorms affecting northern central coastal waters and the nature coast early before moving south into central and southern sections while diminishing in coverage over the course of the afternoon and evening hours as the front slowly sags south into peninsula. Surface flow will veer to northerly behind the boundary Thursday into Friday allowing a short-lived intrusion of cooler and drier air into the area. Flow will begin transitioning back to southeast during the day Friday as high pressure builds to the northeast and an area of low pressure develops over the western central gulf in response to shortwave energy moving across the southeast. Guidance has come into a bit better agreement in tracking the system northeast toward the central gulf coast Friday into Saturday with a plume of tropical moisture likely spreading northeast on its eastern flank. The eastern extent of both the eventual track and moisture shield will determine local impacts for the weekend, which for now remain increased likelihoods of cloudy conditions and showers and storms Saturday into Sunday. High pressure looks to build across the peninsula early next week south of the remnant boundary across the southeast with lingering moisture likely leading isolated showers before another mid upper- |
level trough digs southeast across the central plains and drives another frontal system into the region. Aviation... vfr conditions expected across terminals throughout period except MVFR CIGS possible through around 13z at kpgd, kfmy and krsw.

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. |
