The final week of summer (traditional and meteorological) has arrived, and for the most part, the weather will be fairly nice, but a little on the cool side.
We start the week off with some rain across the Cape and Islands as a weak low pressure area passes by offshore. The rain should end during the morning, but we’ve got a cold front moving in from the west. We could see some sunshine, especially inland during the morning, but as the front moves in, we’ll see some showers and thunderstorms developing in the afternoon. They shouldn’t be that strong, but a few could produce some gusty winds and heavy downpours. They’ll quickly subside during the evening as the front pushes offshore, then high pressure starts to build in with cooler and drier conditions. However, we’ll also have an upper-level low pressure area moving in from the Great Lakes, and this will likely generate some clouds for Tuesday afternoon. It’ll probably be a little too dry for any showers to pop up, but it wouldn’t be a complete shock if a few days. Another disturbance rotating around that upper low will move in for Wednesday, with some morning sun followed by afternoon clouds, and this day may feature a better chance for some pop-up showers during the afternoon. Thursday looks like another dry day with some afternoon clouds and temperatures that remain a little below normal for late August.
As we get to Labor Day weekend, we’ll see another low pressure area moving in on Friday, with another round of showers and possibly some thunderstorms. The system will take its time moving out as another upper-level low moves in, so Saturday may feature more clouds and a few showers, especially early, but we should see some improvement during the afternoon. Sunday looks pretty nice, but we’ll still have an upper-level low nearby, so expect more clouds, but for now, we’re not expecting more showers. High pressure builds in for Labor Day with dry and seasonably warm conditions, though some clouds are still likely as that upper-level low will be slow to depart.
