Showers and thunderstorms will remain a daily occurrence for the late portion of this week, though coverage may be somewhat limited compared to previous days. This should result in slightly hotter and drier conditions for most, with relative humidity falling to the 40s or around 50 percent inland. Closer to the coast, look for RH to stay up in the 50-60 percent range. Winds will be light and fairly variable, but mostly south to southeast prior to a front arriving this weekend. This front will bring back increased storm coverage over the weekend, followed by a modest bit of drier air filtering in well inland early next week. .REST OF TODAY...
