10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome. 10/4/2018 I have fixed XTide and updated the harmonic files. There were some name changes so you might have to click EDIT to find the new station name. |

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus64 klix 250916 afdlix area forecast discussion national weather service new orleans la 416 am cdt Sat may 25 2019 Short term No appreciable changes in the ongoing fcast this morning. Stacked ridging will give way a bit as the front currently located over the central CONUS gets a bit of a push to make its way to near our area by mid to late next week, obviously a very slow process. This will weaken the ridge but there looks to be enough mid layer subsidence provided by the high to keep thunderstorm numbers lower than what we currently see with this front. As we get into the middle of next week there will be a better idea of the type of activity that will be associated with this front. Eventhough the front stalls over northern la ms, there could be just enough destabilizing effects to get enough cloud cover and sh TS to develop farther south of the front. At the moment, this looks like a simple isolated downburst type pattern with the dry air layers provided by the ridging that is still holding just east and southeast of the area. This is still a ways out especially for fcasting even isolated to scattered thunderstorms. Aviation As has been the case the last few nights, brief flight restrictions can be expected this morning at several terminals. So far this morning, the restrictions have been at khum and kasd. Kasd has been down to ifr, with khum at MVFR. Can't rule out other locations seeing similar conditions. Any restrictions should improve toVFR around 14z. The remainder of the daytime hours will beVFR. Again overnight, primarily in the 07-14z Sunday window, brief flight restrictions will again be possible. 35 Marine Upper ridging over the southeastern us will keep a persistent wind flow in the east to south quadrant through the forecast period. Do not expect winds to get much above 15 knots through the forecast period, and do not anticipate any lengthy periods of exercise caution conditions, if they occur at all. 35 Decision support |

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. |
