.SOUNDING DISCUSSION...
This morning's balloon launch was successful, and there were no
issues. Looking at the sounding, the vertical profile is generally
dry throughout the atmospheric column. There is a small
temperature inversion at the surface which will dissipate as the
sun causes atmospheric mixing. The CAPE is very low today (252
J/kg in the mixed layer), and the CIN is higher than usual today
as well (-252 J/kg in the mixed layer). This combination of high
CIN and lower CAPE will really inhibit convection throughout the
morning and some of the day. The vertical wind profile is fairly
uniform throughout the atmospheric column. The winds at the
lower and middle levels are mostly westerly and strong (30 
knots). The winds at the upper levels and at the jet stream are
primarily northerly in direction and strong (50 knots). MSW
