We have a case where we only have one hour of forecast data. METRo
crashes for this case:
EXECUTION : METRO_PREPROCESS_INTERPOL_FORECAST module: start execution
Traceback (most recent call last):

raise "METRoUtilError", sMetroUtilError
METRoUtilError: In interpolate, the arrays have only one value (1)
It looks like METRo can't interpolate with one forecast value. Should
it be case that METRo has to have more than one hour's worth of forecast
data? I checked in the documentation on the wiki, but I didn't see any
restrictions regarding the number of hours of forecast data that is
required, so I thought I'd check with you.
Thanks,
Julie
