.SOUNDING DISCUSSION...

The 00z sounding continues to show a stable atmosphere in place
with weak lapse rates around 5.5C/km, and no CAPE to speak of.
However, moisture continues to advect into the mid and upper
levels of the atmosphere on the back of a strong 145 knot jet
at 200mb. This was noted by the altostratus and cirrostratus decks
observed at launch time. As moisture levels in the mid and upper
levels increase, the precipitable water values have also risen to
over 0.50 inches today. However, a deep pool of dry air continues
to reside below 700mb, and a weak temperature inversion is noted
around 900mb due to this continued dry pool in the low levels. 32
