Interpreting the BSRi

A visual of the Bering Sea Rule Index. More info can be found here.

Going deeper. In Joseph Renken's 24OCT14 LR Disco he states "matches a storm threat for Central Missouri on the 12th of November" via the Typhoon Rule (based off a long range model I assume) AND then states "there will be storms during November 14th and 16th" via the BSR (based off a short range model I assume). Same or different energy? Anyway, the solutions presented below have begun to show up in the BSRi (image at bottom), and match what was discussed in JD's latest.

Plugging the ISO/RR. A ~34 day dominant harmonic gives us the solution below, connecting mid November dates bolded above.

KCOU could be looking at their first hard freeze of the season.

I think the BSRi shows this well (image below). A large negative change in SLP that basically holds there with minimal slow positive change for a few days following the referenced time frame.
