First Look at the Weekend

A close pass by a coastal storm will bring some rain to Southern New England on Friday.  An upper-level low will cross the region Friday PM which will bring with it a chance of showers.  A front will try to pass on Saturday, but it will be beaten back by a strengthening ridge in the SW Atlantic.  Temperatures Friday will remain below average but a warming trend will begin on Saturday.  Temperatures Sunday will be in the mid to upper 80's (isolated 90's).

Friday
The projected surface map Friday AM shows a trough over the Northeast and a coastal low just close enough to bring rain to the Cape and Islands.

Computer guidance has trended east with this system which is good news.  Some interaction with the upper atmosphere trough will likely enhance a band of rain in Central New England.  This may set up near Essex County.  Traditionally, these types of troughs are strongest where the coast has a concave enclave.  Southern ME and NH is a good example of this.

You can see the low to mid 60's in Maine as they should take the most rain from this system.  In SNE, temperatures will rise into the mid 70's in the CT River Valley and low 70's for everyone else.   The showers in SNE will be early to mid-afternoon with clearing skies for the evening.

Saturday
A stalled frontal boundary will linger Saturday AM and PM without ever passing through the region.  The presence of this boundary will touch off a few showers and thunderstorms, but this will be isolated.  Here is that boundary as of 8 AM Saturday.

Cloud cover/showers will peak midday before clearing later Saturday PM and evening.  This is not a washout nor a thunderstorm outbreak so if you have plans or parties scheduled continue without worrying.  Temperatures will climb into the mid to upper 70's in SNE.  Temperatures will climb into the low 70's in NH and ME.

Sunday
The stalled boundary will lift north Saturday night as a warm front.  Our winds will shift and the warm summer-like weather will return.  Lows Sunday AM will be in the low 60's.  Temperatures will rise into the mid to upper 80's, even in Maine.  There will be a bit of a sea breeze but it won't be overwhelming.

As for precipitation, the only place I see the chance on Sunday is in far Northern New England.  A series of disturbances will ride the boundary to our north.  This will be updated as the weekend getaway forecast on Friday.
