GMZ400 Synopsis For Lower Atchafalaya River La To High Island Tx Out 60 Nm Including Sabine And Calcasieu Lakes And Vermilion Bay 333 Pm Cdt Sat Aug 17 2019
Synopsis.. Current weather pattern largely continues with elevated chances of Thunderstorms in the afternoon and isolated activity a continued possibility through the overnight hours. Light to moderate onshore flow is expected to continue through at least early next week. Fluctuations in the placement of high pressure in the gulf will potentially lead to some variability in the winds by mid week, but light to moderate southerly flow reestablishes itself by the latter half of the week.

Aviation A few showers will still be possible through about 18 01z, then any convection that has develop will likely dissipate with the loss of daytime heating.VFR conditions are then expected for the remainder of the night. Southerly winds will continue to bring in abundant gulf moisture on Sunday, and with a relative weakness aloft, daytime heating should initiate scattered showers and thunderstorms as earlier as just after sunrise, with the majority of the activity occurring after 18 17z. Rua Prev discussion issued 306 pm cdt Sat aug 17 2019 discussion... another hot and humid summer day ongoing this afternoon. Radar showing plenty of scattered convection around the region, and this will likely continue to be the case as we move into the evening hours. Following sunset and loss of heating, activity should begin to subside fairly quickly, leading to yet another warm and muggy overnight period. The overall weather pattern for the next several days appears to be fairly persistent. Shortwave energy will continue to rotate over into the region as the upper level ridge regains some amplitude and fluctuates around the southern plains. In combination with high pwats, this will yield an elevated diurnal cycle with isolated thundershowers in the morning becoming scattered to numerous by the afternoon. In addition, the |
combination of heat and humidity will continue to lead to heat index values rising above 100 almost daily. Heat index values have been flirting with advisory criteria in the NW portion of the cwa this afternoon, and thinking this will be the case the next couple of days. Later forecast packages will continue to monitor this to see if a heat advisory may be warranted. For the longer term, there still is some uncertainty in the finer details of the forecast, but overall a pattern of elevated diurnal convection, and hot humid days seems to persist.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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. |
