Yeah I think that’s been modeled for awhile. It’s feeling the tug from that H5 low.
We get a little meso high over PWM to start and then a lobe from that PV starts digging S of LI and seems to really help back the flow over ENE as we get sfc pressure falls near the BM. I think that’s why we’ve seen a trend on that fropa being delayed Saturday and instead enhanced precip along that slowing sfc convergence zone (inv trough).
