Yes, the AK trough is still there at day 15, but the trough is undercutting in the southern US.
The undercutting “blue” on today’s 12z run has advanced further to the east into the western Carolinas this run vs. last run.
Today’s run also doesn’t connect the southeast ridge with the northern ridge in the east that is lifting up into eastern Canada.
There’s still work to do, but the first step is getting the massive eastern ridging booted out.
