December 28th, 2014
There have been odd signal combinations over this passing
long Christmas Holiday weekend. SD started
out strong but now seems weakened but still manages to push through, weak as it
is (a weakness which I would not have predicted by the higher than normal
pressures over this timeframe). However,
often at the same time SB can be heard across the middle in locations where one
would only expect to hear one or the other, at best; as usually SD would tend
to dominate at that location. It’s
almost as if the scenario changes from moment to moment, to some extent. But SD is still weak, regardless. It doesn’t seem in keeping with any
directional forces of the passing and approaching pressure systems – which seem
to be following odd paths, according to the 11 o’clock nightly news. What’s more, the pressure has not been very
low or nearly as low as expected for as weak as SD is being heard – which might
normally signal problematic air masses for the heartland, according to my
model/hypothesis/theory. (But maybe it’s
the delta/change in pressure that matters, as I postulated before, nevertheless
and not really the signal strength.) But
I do wonder if the reported solar flares that happened at the beginning of the
weekend may have had any effect on the situation.
