NW Flow Continues
A Northwest flow is when the upper-level flow is coming from the Northwest (simple enough). This keeps low level moisture away, advects cooler air into the area, and could give us a breezy NW wind. Sound familiar?
In the above map, you can follow the flow by looking at the lines of equal thickness. The wind will flow along those lines. I drew arrows on the map to illustrate. (Click to enlarge.) This map shows what the upper-flow may be following a reinforcing cold front on Friday morning.
Here's my point. We are in a dry, comfortable, NW Flow and it looks like it may stick around through the weekend!
