.WHAT HAS CHANGED...
Extended the time of the Small Craft Advisory to Monday evening. 
Otherwise, no significant changes to the forecast.

&&

.KEY MESSAGES...

- Unsettled weather continues this weekend as slow low pressure
  slowly moves away into the Gulf of Maine.

- Cloudy through midweek with more seasonable temperatures.

- Unsettled weather may return late this week.

&&

.DISCUSSION...
KEY MESSAGE 1...Unsettled weather moves offshore this morning as
a low pressure slowly moves away into the Gulf of Maine.

Latest surface analysis showed that a low pressure over the Gulf
of Maine, heading toward Nova Scotia. Meanwhile, a mid level low
over southern New England should move offshore later this
morning as well. Scattered showers end early, leaving much of
today dry.

The colder air aloft will result in gusty west to northwest 
winds developing, especially after clouds break up.

Temperatures expected to remain slightly above normal through
Monday.

KEY MESSAGE 2...Cloudy through midweek with more seasonable 
temperatures.

We remain under WNW flow with another upper level trough
clearing the region through Monday night, and with it cooler 
temperatures prevail aloft. 850 mb temperatures look to fall 
below 0C late Monday night then steadily improve through the day
on Tuesday to around 2- 4C. These cooler conditions aloft will 
remain supportive of a mix of clouds and sunshine. Highs Tuesday
look to be generally in the 40s and 50s with lows in the 30s. 
These more seasonable temperatures are expected to continue 
through at least midweek as the WNW to W flow aloft continues. 
Breezy conditions at the surface are expected at least for 
Tuesday as another low looks to pass to our northeast.

KEY MESSAGE 3...Unsettled weather may return late this week.

Towards the second half of next week, guidance has continued to 
indicate possible development of another low pressure
originating from just to the south of the region along/just off 
the mid- Atlantic coast. This looks to be driven by the approach
of an upper level shortwave tracking from the Canadian Prairies
southeast into the mid- Atlantic region. With this possible
system, we could see the return of more unsettled conditions for 
the second half of the week. A lot of spread remains this far
out from this potential system, especially regarding any
potential precipitation associated with it.

Some guidance indicates a decent bit of colder air aloft,
notably 850 mb temperatures below 0C, approaching the region. As 
such, temperatures look to drop off a bit towards the end of the
week, with ensembles showing mean temperatures in the lower 40s
and upper 50s for afternoon highs. Onshore winds may end up 
keeping coastal areas slightly warmer, and any precipitation 
that falls there would lean towards rain. Over the colder 
interior, we could see some rain to wet snow falling. This event
is still towards the day 6 and 7 timeframe of the forecast, so 
much will likely change between now and then regarding the 
details of this system.
