Sounding discussion
The overall atmosphere has changed little from this morning.

Northeast flow persists from 850mb to the surface with a westerly
flow pattern in the mid and upper levels. Moisture content has not
changed much with precipitable water values still around 2.10
inches, and the mean mixing ratio was little changed at 16.7g kg.

Lifted condensation levels remained static around 3000 feet, and
mid-level lapse rates were marginally unstable around 6.0c km.

Convective temperature was also little changed at 87 degrees, and
overall instability values were also little changed with the
lifted index remaining steady at -7c. Overall, the sounding
indicates an marginally unstable atmosphere with little to no
capping and slightly higher than average moisture content
resulting in higher than normal rainfall rates for any convection
that forms. 32

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
