We call it northwest flow. This weather pattern favors dry northwest breezes. Dew points in the 50s and 40s are blowing (advecting) into Minnesota on fresh northwest breezes today. Our inbound air mass is ideal for human comfort. I've overlaid streamlines and dew points over the GOES 1 km visible image below.

The Trump administration has decided to disband the federal advisory panel for the National Climate Assessment, a group aimed at helping policymakers and private-sector officials incorporate the government’s climate analysis into long-term planning.
The charter for the 15-person Advisory Committee for the Sustained National Climate Assessment — which includes academics as well as local officials and corporate representatives — expires Sunday. On Friday, the National Oceanic and Atmospheric Administration’s acting administrator, Ben Friedman, informed the committee’s chair that the agency would not renew the panel.
The National Climate Assessment is supposed to be issued every four years but has come out only three times since passage of the 1990 law calling for such analysis. The next one, due for release in 2018, already has become a contentious issue for the Trump administration.
