 Lower humidity. I'll take it. Temperatures in the 50s and 60s overnight with mainly clear skies. Your Tuesday equally pleasant with temperatures once again back in the mid-80s. Mid to upper 80s with partly sunny skies for Wednesday. By Thursday, heat and humidity due return. It just seems like that always happens for the holiday. Temperature-wise, we'll be back in the 90s. Could be a few storms in the afternoon, hopefully tapering off in time for the fireworks.
