Area Forecast Discussion National Weather Service Lake Charles LA 1121 PM CDT Fri Aug 14 2020

DISCUSSION. For 08/15/2020 06Z TAF Issuance.

AVIATION. Aside from a few very light isolated showers near AEX earlier, radar continues to show quiet conditions across the region. Expect VFR conditions to persist through the overnight hours, with only some patchy BR possible near sunrise. Light southerly to VRB winds overnight begin to pick up from more of westerly direction by late morning as a weak diffuse boundary advances southward towards the region. Winds become more VRB in closer proximity to the front, and could start to shift northerly at AEX for a time if the boundary slides far enough south. Current forecast has the boundary stalling across central LA. Convergence along the boundary is likely to kick off some convection by mid afternoon, but given the scattered nature, only added VCTS at LCH/AEX/LFT/ARA at this time. Convection begins to fizzle out after sunset with a return to light VRB winds overnight and VFR conditions expected.

DISCUSSION . Forecast on track . no update planned.

PREV DISCUSSION . /issued 422 PM CDT Fri Aug 14 2020/

DISCUSSION . A decaying MCS that has been gradually moving southeast from Arkansas through the day has been spawning scattered shower and thunderstorm activity across lower acadiana this afternoon although the most widespread activity has remained across southeast Louisiana and Mississippi. One of these storms was even able to produce a dramatic looking funnel near Avery Island although there was no reports of this funnel reaching the ground.

Expect storms to begin to wane over the next few hours as the energy associated with the MCS departs along with the loss of daytime heating.

The persistent pattern continues into tomorrow with weak high pressure centered over the northeastern gulf maintaining light southerly to southwesterly flow. With diurnal heating providing the only support for convection tomorrow, overall coverage is expected to be somewhat lower with most of the activity once again developing on the eastern periphery of the large upper level ridge centered over much of the southwestern U.S.

As this ridge retrogrades west Sunday into Monday, guidance continues to depict a southward diving upper trof driving a weak surface front through the area Sunday into Monday. There continues to be some run to run variation regarding temperatures and moisture behind the front and while the change in airmass is expected to be noticeable, the change in dewpoint (upper 60s to lower 70s) will be more significant than the change in temperatures.

Upper level moisture will quickly return as a series of weak disturbances propagates around the broad upper trof that will become entrenched across the eastern U.S. through much of next week. This will reestablish daily afternoon thunderstorm development through the end of the week.

MARINE . Light southwest to west winds will continue through the weekend as weak surface high pressure extends across the northern Gulf of Mexico. Isolated to widely scattered showers and thunderstorms will be possible. A cold front is expected to move through the coastal waters Monday bringing a light offshore flow through Tuesday.

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.
