Broad upper ridge expected to continue from the W atlantic through the gulf region to over tx with a general weakness in the ridge from the NE gulf into the deep south today through mid week. Western atlantic surface high pressure ridge axis now over S fl to slowly lift nward today as deep south frontal boundary washes out. Deep SW flow continues over N fl for another day of numerous showers and thunderstorms with highest rain chances over the N nature coast as areal flooding persists across levy and northwest citrus counties, and additional rain will make it difficult for flood waters to recede so will continue flood watch for those areas today. Central and SW fl zones begin transistion to se-s low level flow precip regimes today, mainly along diurnal seabreeze and outflow boundaries. As surface ridge axis weakens and holds over the c fl peninsula through late week, precip will develop primarily on afternoon into evening boundary interactions. By the end of the week into next weekend series of northern stream upper troughs further suppress upper ridging over the region with summertime temps and rain chances continuing. Aviation |

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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. |
