After a wacky weather day yesterday – which featured several thunderstorms and multiple reports of tornadoes and waterspouts across Southern New England…including at least two waterspouts here on the Cape(!) – things are turning quieter and cooler for the mid to late week period.
Expect drier air to take hold of the region over the next couple of days with increasing amounts of sunshine and daytime temperatures on the cool side of things…with highs generally within in a couple of degrees either side of 50F Wednesday, Thursday and Friday. An active breeze will make things feel cooler at times.
Unfortunately, the quiet Fall weather won’t hang on for too long as our next weather-maker…a coastal storm…will approach the region on Saturday and bring us a round of heavy rain and strong onshore winds.
Based on current guidance, Saturday is looking to be the uglier of the two weekend days as low pressure lifts northward from the Carolinas and spreads a shield of rain over the area. The storm will pass very near to the Cape Saturday night and Sunday morning, eventually shifting away from the region over the course of the day on Sunday.
At the current time, upwards of 1 to 2 inches of rain is looking like a good possibility and a period of east and northeast winds gusting to 40 to 50 mph is likely. In fact, depending upon the exact evolution of the storm, even higher amounts of rain and stronger wind gusts are possible.
The strong easterly flow combined with higher than normal tides means will have to watch out for areas of beach erosion and coastal flooding. Those details will become more clear over the next 48 hours.
