The front moved through this morning replacing the humid air with drier, more comfortable air. Dewpoints are back down into the 30s and 40s, so the air is much drier and less humid than the past couple of days. The less humid air will stick around for the rest of the work week, but as southerly winds kick in by the weekend, you will probably notice an increase in the humidity as dewpoints should climb back into the lower 60s. The added moisture in the air may help fuel thunderstorms on Saturday as well.
Overall, I'd say we have had a great transition from winter to summer so far.
