Significant Weather Weekly Outlook

Hazardous weather is not expected this weekend into early next week.  This update just clarifies what to expect this weekend into early next week.

The combination of a passing upper-level trough of low pressure through a somewhat unstable air mass is resulting in areas of showers this Saturday morning.  For most locations, the afternoon should be drier, although cannot rule out a spot shower here and there.

An offshore low pressure system (moderate intensity for May) will pass southeast of New England but close enough to bring rain to Cape Cod and adjacent areas of southeast MA and RI late tonight and Sunday morning.  A half inch or so of rain may fall over the Cape with this system.  Brisk north to northeast winds will keep temperatures mainly in the mid to upper 40s across the Cape and result in choppy waters off the Cape and Islands. Conditions should start to dry out Sunday afternoon on the Cape.  Central and western MA as well as CT will likely experience some high to mid clouds Sunday morning but escape the rain.

Mostly sunny and warmer weather is expected for Monday and Tuesday across southern New England.
