(About the SPC Analyses Used here at
times: The
00z maps are produced at 01z using the available upper
air data with a first guess from the 18z NAM 6-hour
forecast for the objective analysis. The 12z maps are
produced at 13z using the 06z NAM 6-hour forecast as a
first guess for the objective analysis. If the 18z or
06z NAM runs are unavailable, a first guess from the
12-hour forecast of the 00z or 12z NAM is used. Errors
may result if NAM model data is not available, or if
sounding data is late or erroneous. )
