Wintry January 14-16th storm potential.

regarding "i would expect more precip from that!", i've thought that a lot too about trailing waves before. my thinking is that the lead "impulse" wave creates subsidence in its wake and CAA pulls in stabler air at the surface, so the trailing wave is fighting both of those things. it makes cyclogenesis harder since the boundary is further offshore and the lift generated from the trailing wave is fight an preceding airmass promoting sinking air

so the MS valley shortwave is fighting subsidence behind the NE wave
