(This thread follows in line with one similar covering the same idea where looking at this past Summer. @)

.. On the 28th of September, colder airmassthat looked at more broad scope from east to west, fuller Northern hemisphere, and that had been present and caused to move and spread more southward during the period approximately two weeks previous @began to regress more northward again, and should continue to do daily, through to the 11th of October.

This looking at broader cold's more latitudinal leaning, while more longitudinally, main and broader cold is caused to transition, at about this point, from its more slowed movement east, begun back on the 20th or so of September, to a brief period of more stepped up pace east through the 5th, before slowing gradually, daily, from then through also near to the 11th of October.
 
No "Numerical Wx-forecast Models" have been consulted where considering the generation of the broader outlook included above as part of this post.  Further, the more-abstract ideas represented above, are theoretical in nature, only. And so, as such, have been submitted here, only as conjecture  certainly open to discussion.

.. With the culmination of its current [period of] general regression more northward dailybegun back on the 28th of September, .. On the 11th of October, main cold air massthat looked at across the board from east to west, fuller Northern Hemispheric scopewill begin to move and spread, daily, progressively more southward, with continuing to do so through to the 25th of October. 
 
With its regression, and where also considering the degree of more positive consolidation of cold northward within and through the higher latitude concurrent with this regression, .. with its spread daily more southward, the first more significant cold of this fall, generated and stored more mainly as a result of progressively shorter day-length, should be brought from the north southward into the mid-latitudes, during this period.
 
 With this more latitudinal more southward distribution of main colder air, where looking at that same cold's more longitudinal flow through this same period, boarder cold should transition from its current generally slowing movement to a pace steadily more stepped up eastward through to the 19th, before beginning to slow gradually again, daily more, on the 20th of October.

Hopefully this brings some rain to most of CA, which desperately needs it after this terrible fire outbreak in the Napa Valley and surrounding areas.
