This moisture will support scattered to locally numerous showers and thunderstorms although with slightly less coverage especially in the north thu. Timing both days will be late mornings or early afternoons inland then shifting toward the gulf coast later in the afternoons and offshore and winding down in the evenings. The copious rainfall of the past few days has resulted in a quite saturated ground... maintaining the threat of localized flooding and additional rises on area rivers. During Fri through tue: for the weekend the atlantic surface ridge axis resides across north fl while the inverted trough tracks across the southern portion of the state and slides out over the gulf. These features provide an easterly to southeasterly 1000-700mb flow. Then for early next week a frontal boundary settles down into the gulf coastal and southeastern states... Shunting the ridge axis down into central then southern fl. As a result the 1000-700mb flow turns to the south and southwest. Sufficient moisture will be in place for scattered to at times numerous showers and storms. Through most of the weekend these form inland... Track across the gulf coast in the afternoons |

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. |
