High pressure remains in control today, persisting clear skies, before a mid-week storm brings the next chance for showers and storms. The pleasant day will subside as clouds will build as the day progresses ahead of a warm front. The front will move through overnight tonight into Thursday, bringing higher temperatures and humidity, as well as the threat for a few showers. A more pronounced rain threat will come with the cold front which will sweep across the Commonwealth by Thursday night. Behind the cold front, skies will clear and fair weather will return as high pressure returns for the day on Friday. High pressure remains in control into Saturday when a weak front will bring clouds and yet another chance for precipitation.
