844 am edt Wed jun 19 2019

Update
Upper shortwave trough continues in E central gulf wrapping
vort MAX upper energy over the area this morning along with
surface outflow boundaries to combine and produce showers
and thunderstorms in SW fl and E gulf this morning. So,
continue to expect more typical s-sw flow pattern to redevelop
with showers already in E gulf to move ashore through the
morning hours then push inland through the afternoon. Only minor
adjustments to grids based on radar satellite trends, otherwise
forecast in good shape.

Aviation
Showers and thunderstorms continue over SW fl to keep vcts
in southern terminals with possible brief localized MVFR ifr
conditions. Additional showers storms expected to redevelop
elsewhere in coastal areas this morning to move inland this
afternoon on SW flow.

discussion...

broad cyclonic flow continues across the southeast with a shortwave
moving across the eastern gulf of mexico and florida. This helped
generate a line of showers and thunderstorms that moved over the gulf
and into the tampa bay region. These will continue to sink slowly
southward over the next few hours, though the line is becoming more
broken with time. At the surface, the atlantic ridge axis stretches
over south florida, with a southwest low-level flow remaining in
place. For the rest of today, precipitable water values are forecast
to be around 2 inches, with scattered to numerous showers and
thunderstorms expected. These will generally shift toward inland
areas through the afternoon and evening. Mid upper ridging then
starts to build over the region on Thursday, although onshore flow
will continue, with scattered rain chances expected. The ridge will
build even more for Friday and into the weekend and early next week,
with some relatively drier air moving in, bringing lower rain
chances. Low-level flow will become lighter as surface high pressure
settles over florida with the best rain chances forecast to be away
from the immediate coast. Conditions otherwise will be typically warm
and humid.

Marine...

high pressure south of the area will keep a southwest wind flow in
place across the waters through the next several days. No headlines
are expected, though winds and seas will be higher in or near any
showers and thunderstorms.

Fire weather...

no fire weather concerns as relative humidity values will remain
above critical levels. No significant fog is expected.

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.
