It's 70 degrees outside right now.  There is a light breeze coming from the Southeast.  Relative humidity has plummeted since the morning.  The reason for this is that the same amount of moisture is in the air but as it warms the air's actual capacity for moisture increases.  Parallel to that, the pressure has been steadily declining since this morning because warm air is less dense, exerting less pressure.  Looking at the winds chart I see a low cell moving our way from the Dakotas.  This is pushing that high cell that was dominating us yesterday out.  This new cell is responsible for the Southeast winds we are getting which is the reason it is so warm.  If you look at Michigan which is still on the cusp of that high cell, they have Northwest winds and it's probably a bit colder there and maybe rainy.
