Marine Weather and Tides
Version 3.4 |
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues. |

The east to northeast low level flow will continue and therefore with daytime heating and the sea breezes we should see convection develop and move westward with the highest pops along the coastal counties during the late afternoon and early evening. The deepest moisture, precipitable water between 1.8 and 2 inches will remain across our northern and southern zones with lower values, less than 1.6 inches, across central florida. Therefore, the best chances of seeing convection will be across the northern nature coast and southwest florida. Convection will move offshore during each evening with partly cloudy skies during the overnight hours. Temperatures will remain near to above normal with overnight lows in the 70s and daytime highs on Wednesday in the upper 80s to mid 90s. Mid term long term (Tuesday night - Monday) Aloft - ridging initially centered over the southeast corner of the nation slowly shifts out over the atlantic and flattens some as a low trough tracks from the central plains to southeast canada by sun. The ridging shifts back west across fl and the eastern gulf of mexico mon. Surface - atlantic high pressure broadly ridges across fl and over much of the gulf of mexico. It S axis resides through north-central fl at mid-week but slowly slides down the state... In response to a boundary trough moving across the gulf coastal states... And reaches south fl thu. The axis remains there through the weekend then begins to lift north for the start of next week. A warm and moist air mass will support showers and thunderstorms with generally scattered coverage. Light flow Wed will favor the interior with the most coverage. Then as the ridge axis moves south westerly flow takes over for Thu with late morning early afternoon showers and storms over coastal counties that shift inland and eastward during the afternoon and early evening hours. This westerly flow will provide an increase in moisture with some enhanced shower and storm coverage for the weekend. Mon will be a transition day as westerly flow gives way to easterly with more uniform shower storm coverage over the area. Temperatures run on the warm side of normal. |
Aviation Isolated to scattered showers and thunderstorms could cause some MVFR local ifr conditions this afternoon and early evening, then convection will move west out into the gulf during the late evening with mainlyVFR conditions prevailing overnight. Some more MVFR ceilings will be possible Wednesday morning once daytime heating gets underway. Brief gusty winds up to around 30 knots will be possible in convection, otherwise easterly winds at 10 knots or less will shift to onshore at tpa, pie, and srq as the sea breeze moves inland this afternoon and again Wednesday afternoon. Marine Surface high pressure will extend southwest across the north central florida peninsula today then sink south to across the southern peninsula by the end of the week. Tranquil boating conditions with light northeast to east winds with slight seas and an onshore sea breeze component developing along the coast in the afternoon can be expected across the waters through Wednesday with scattered thunderstorms during the late afternoon and evening hours through Wednesday.

Wind and seas will be higher in the vicinity of thunderstorms, otherwise no headlines are expected.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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 numerious 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. |
