Sounding discussion A moisture laden atmosphere is noted at 00z
with moist adiabatic lapse rates and near saturation observed
below 600mb. A light south wind is also observed below 600mb, and
this has allowed for moisture transport to occur. Precipitable
water values responded to this moisture transport and rose by 0.21
inches to 2.26 inches. Mean mixing ratio also increased by 1g kg
to 17.3g kg. Although the sounding indicated weaker more moist
adiabatic lapse rates, there was still plenty of atmospheric
instability observed in the sounding. MLCAPE values were around
1600 j kg and the convective temperatures was a low 85f. The
effects of this instability in the low and mid-levels of the
atmosphere was observed by towering cumulus and a nearby shower at
launch time. Above 600mb, a north wind is in place, and some drier
air was noted between 600mb and 400mb. This north wind was also
observed by sight at the launch as a cirrus deck blowing to the
south from nearby convection. 32

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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.
