Discussion              

The overall weather pattern has evolved into one that will be considerably wetter for the Mid-Atlantic region in coming days compared to what was experienced earlier this month and during May. Today will be unseasonably cool with a persistent ocean flow of air (i.e., east-to-northeast winds) given the combination of high pressure to the north and low pressure to the south. There can be a shower from time-to-time today or some patchy drizzle, but significant rainfall is not looking too likely. More rain is destined to arrive here later tonight and for Friday and there can be a thunderstorm or two mixed in…some of the rain late tonight and tomorrow can be heavy at times. A daily threat of showers and thunderstorms this weekend looks like it will continue through much of next week. Conditions do turn somewhat warmer on Friday and then temperatures likely reach into the 80’s during the weekend and early part of next week.
