Interaction between high pressure ridging over southern florida and troughing over the east coast is keeping a southwest wind flow over the region resulting in a moisture rich environment. The 12z morning sounding showed a reflection of this with 2.18 inches pwat and southwest winds through 20k feet. Latest hrrr guidance keeps rain chances high with 50-80% pops expected across the region today with the highest chances north of tampa bay. Based on latest surface observations and satellite imagery, the forecast looks good for now with no major changes needed. Aviation We continue to remain in a very moist and unstable southwest flow through the day. Shra with embedded tsra can be expected through the forecast period with southwest winds around 5-10 knots. The highest rain storm chances will be from ksrq northward with brief periods of MVFR ifr conditions possible through this afternoon, so will hold vcts through 00z and will closely monitor radar for needed tempo changes through the day.

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. |
