So I wake up this morning to find an SPS from Norman WFO about the possibility of snow or ice late Wednesday into Thursday and immediately I'm intrigued. I'm a big fan of the warm weather and thunderstorms but I could stand a little wintry precipitation right now.
Checking out the GFS BUFR forecast soundings for OUN it looks like all our post-frontal precip that it is depicting on Thursday would indeed be snow. Time cross-sections show RH in the dendritic growth zone right around 90%, although best vertical motion displaced about 4000' below the DGZ. However, also interesting to note that the GFS does allow for some elevated instability to develop. DGEX in fair agreement with the GFS as is the ECMWF.
Thus I pose the question...are they depicting the evolution of this system fairly well or not. I'm starting to get my hopes up for a few flakes so I sure hope so!
