SPC SREF SREF_maxtop_totalprob_mid

Please Note: Several problems have developed in the SREF related to vertical velocity and precipiation type fields (updated 2012-12-21):
Precip Type: A problem has developed with the precipitation type grids from the WRF-ARW members, which adversely affects precipitation type and snow amount fields. Click here for more info.
Vertical Velocity: Several graphics that are dependent on vertical velocity have been removed, owing to incorrect vertical velocity fields in the NMM and NMMB members. Click here for more info.
