Enjoy whatever sunshine we get today because rain is about to become our friend for the next week. High pressure is quickly scooting eastward across the region today. That will bring a mix of sun and clouds and a high in the lower 80s. There's enough moisture around that there's a slight chance of an isolated shower this afternoon, but you're probably safe leaving your umbrella at home.

Over the weekend it looks like two upper-level troughs will develop, one over the Canadian Maritimes and the other over Hudson Bay. The Hudson Bay guy is going to toss a series of short wave disturbances toward the Maritime guy. As each one passes over our region it will produce clouds and perhaps rain. The rain shouldn't start until tomorrow afternoon at the earliest. The first short wave tomorrow night or Sunday will have some help from a warm front, so look for showers or thunderstorms and perhaps a good amount of rain. Don't let the chance of rain discourage you from going to the National Weather Service's open house at Brookhaven National Lab on Sunday.

Showers and thunderstorms look like they will stick around through at least Wednesday, if not longer, while the two Canadian troughs work out their issues. Daily highs will be in the lower to mid 80s and morning lows should be in the lower 70s.
