After a string of fair weather and seasonable temperatures the last several days, the weather will turn decidedly more unsettled this week. A cold front will approach the region from the north and west today and attempt to pass through the area overnight tonight. This front will decelerate in its approach and allow abundant moisture to stream northward along and ahead of it providing the set up for copious rainfall across the region this afternoon through the first half of Wednesday. Flood watches have been issued for the region through Thursday morning as present data indicates the possibility of 2 to as much as 4 inches of rain may fall across portions of the region through this time period.
The frontal system will stall to the south of the region on Wednesday, keeping lots of cloud cover around the area. Though steady rains should abate by late Wednesday afternoon, the continued risk of some showers through Thursday morning cannot be ruled out.
A highly unsettled period continues to play out through the end of the week and into at least the start of the weekend as the stalled boundary interacts with a tropical system, and coastal low pressure looks to develop over the southern New England coast by Saturday night, and lifts north into the Canadian Maritimes by Sunday morning. Lots of clouds and occasional showers are forecast through this period with slowly improving conditions for the second half of the weekend.
