Discussion
Our recent stretch of nice weather with generally rain-free conditions and comfortable temperatures and humidity levels has come to an end. High pressure that has been to our north in recent days has shifted off the east coast and this new positioning has opened the door for more humid air to push into the region. In addition, an upper-level disturbance that has been spinning over the Carolinas in recent days is now making a move to the north and this combined with the higher humidity has increased our chances for showers and thunderstorms. Indeed, this threat of rain will stick around not only for the rest of the work week, but also for the weekend and at least the first half of next week. The rain chances over the next several days will be highest during the afternoon and evening hours as it will tend to be “diurnally-driven” with daytime heating playing an important catalyst type of role. Another strong upper-level low pressure system may impact our region by the latter part of next week.
