Soundings: what weather balloons measured

SPC’s skew-T diagram and hodograph of the sounding at VPS, 14Z. Its levels are in the table below.
Observed Sounding at VPS, for (37 h 50 min ago) older than the last two launches. SPC’s graphic; the values in its panels (CAPE, shear, the indices) are SPC’s computations from these levels. Data: NOAA/SPC.

A balloon launched about an hour before the time named, measuring as it rose and drifted with the wind: the atmosphere above one place, at one time. Model soundings, which are forecasts, are not shown here.

The levels this sounding was drawn from (48)
VPS: the surface first, then up through the atmosphere. Temperature and dew point in °C, as measured.
