If you spent any time outdoors today chances are you noticed the sky changing color as high cloudiness came streaming in. The clouds are the forerunner of a storm system that will be slowly moving our way over the next 36 hours bringing the threat of showers or thunderstorms. The activity should be pretty spotty tonight and then become more widespread Wednesday afternoon as the storm gets closer. Southerly winds promise to transport plenty of moisture our way and this could lead to heavy downpours and localized flooding. The system is expected to stall in the Gulf of Maine Wednesday night so showers will be likely into Thursday. The models don't agree on how quickly the rain will end on Thursday so we'll have to wait for them to come into some agreement before saying for sure how long the rain will last. Partial sunshine should return for Friday making for another hot and humid day. A cold front is going to move our way and supposedly push through our region Friday night. Once again the models don't agree on this. If it does go through Saturday will feature cooler and less humid conditions. Let's hope this comes to fruition.
