I was checking on GPS PW this afternoon (see time series above - WRF-GFS had forecast PW to drop dramatically this afternoon) and noted that the situation was strange at 0000 UTC yesterday afternoon. The afternoon sounding was much wetter than the GPS data were - the opposite of the usual summer scenario with the RRS soundings. So, I checked to see what the sounding looked like (Univ. of Wyoming skew-T plot below). Looks like the bad sounding was taken in/near the thunderstorms that developed near the airpport yesterday afternoon - note the severe super-adiabatic layer above the apparent updraft layer. So it goes. Note that we're back to "normal" this evening.
