found this kind of interesting from a discussion down south.. I thought this was a thing of the past?
Overnight, the system weakens a
bit, but spreads over all of our area with showers based on the
00Z GFS. The 06Z is a little less certain with coverage, so we
will wait on the 12Z. This is why we launch balloons twice a day
to cover the cool and hot charts. Off hour runs should always be
taken with a grain of salt.
