Sounding discussion
The 00z sounding shows a colder and more stable layer of air
extending below 750mb to the surface. This cold and stable airmass
is also significantly drier than the airmass above as noted by a
low 850mb rh of only around 25 percent. The cold pool in the low
levels has also produced a decent temperature inversion between
the surface and 750mb of around 1.5c. The combination of this
temperature invesion along with the dry air has resulted in no
cloud formation in the low levels of the atmosphere today.

However, above 750mb strong west-southwest flow has continued to
pump in a very moist and more unstable airmass in the mid and
upper levels of the atmosphere. This is little changed from the
12z sounding with the only noticable difference being a continued
warming of the temperatures aloft. This has pushed the freezing
level up from 9600 to 11400 feet since the 12z sounding.

Otherwise, the atmosphere aloft is nearly saturated and lapse
rates are moist adiabatic in nature. The dense shield of
altostratus observed at launch should persist according to the
latest sounding. 32

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.
