Area Forecast Discussion National Weather Service New Orleans LA 717 AM CST Sat Jan 18 2020

SOUNDING DISCUSSION. The 12z sounding indicates a small degree of instability in place as largely moist adiabatic lapse rates dominate the atmospheric column. Shear values are impressive this morning with SRH in the lowest 3km of over 300m2/s2, but the lack of instability will limit the severe potential today as little in the way of thunderstorm activity is forecast. The atmosphere is is moisture loaded with precipitable water values of 1.50 inches observed this morning, and this will support some locally heavy showers during the day. PG

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 numerous 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.
