Today will bring the last of some of the more pleasant weather across the Commonwealth. The upcoming week features a low pressure system passing through late this week, followed by a gradual warm-up. Showers and thunderstorms arrive beginning Thursday morning and will work their way across the region, moving out by the early hours of Saturday morning. Temperatures these days will stay mainly consistent in the lower to mid 80s for most. The sun will return on Saturday which will transition to a warming period for the Commonwealth, but temperatures will remain in the low to mid 80s yet again. Some could see temperatures climb into the upper 80s by Sunday, but with a mix of clouds and sun for most.
