Watching 2 systems

There is a low pressure center forming down by the Carolina coast. There is another one right behind it, over the SE states. The first storm is weak, and will pass well to the south of the region on Tuesday night. However, a shower may clip the south coast. Then on Wednesday the second, stronger system will approach and will provide the region with showers and a brisk NE wind on Wednesday afternoon and evening.

Boston forecast:

Tonight: A moonlit sky, with a low around 43 Downtown, 40 in JP and 34 in the coldest areas. Frost is possible in some of the interior suburbs.
