SOUNDING DISCUSSION. As compared to the 12z sounding, the 00z sounding indicates that significant moisture advection has occurred below 700mb in the last 12 hours. Mid-level relative humidity values have increased by over 20%, and precipitable water values have climbed by nearly a third of an inch. Above 700mb, there has been little change with a deep pool of moisture remaining in place. A jet streak is also noted at 250mb where winds have increased to around 100 knots versus the 85 knots observed at 12z. The combination of increased lift from the jet streak and increasing moisture will allow for continued cloud and rain shower development tonight.

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.
