.WHAT HAS CHANGED...
Extended the time of the Small Craft Advisory 
for the eastern waters to 18z today. Otherwise, the forecast remains 
on track.

.DISCUSSION...
KEY MESSAGE 1...Stretch of dry weather with cold nights continues 
for the first part of the week. A moderating temperature trend 
arrives later in the week. 

Upper ridging and surface high pressure will dominate through the 
upcoming week and weekend resulting in a prolonged stretch of dry 
weather. Southern New England will be in a cooler post-frontal 
airmass today with 925mb temperatures ranging +1C to +4C. This will 
support high temperatures in the mid to upper 50s. Locations along 
the Cape/Islands and even portions of the east coast may be limited 
to the low 50s given the N/NNE onshore wind component. Even cooler 
conditions arrive overnight with ideal radiational cooling. The 
combination of mostly clear skies and boundary layer decoupling 
allows lows to fall into the 30s across urban/coastal areas and the 
lower to mid 20s further inland. Guidance even hints at lows 
approaching either side of 20 degrees across areas of northern 
Franklin and Worcester counties by Wednesday morning. Less cooling 
may be realized further west as mid and high clouds filter in from 
the west through the overnight. 

The theme of dry and cooler weather continues Wednesday. 
Temperatures trend slightly warmer as a mid level ridge shifts 
further east into the region accompanied by warmer temperatures 
aloft. The warming trend in temperatures continues into late-week 
resulting in 925mb temperatures warming to +10 to +13C. This will 
yield high temperatures in the mid-60s on Thursday which is 
seasonably warm for this time of year. Despite the mid-level pattern 
becoming more zonal Friday (ahead of our next weak wave), the 
westerly flow will support efficient mixing in the boundary layer. 
This will result in a breezy, but likely the warmest day of the week 
with high temperatures in the upper 60s and even low 70s in portions 
of southern New England. NBM highlights moderate to high 
probabilities(60%-80%+) for 70F or greater across the valleys, CT, 
and I-95 corridor. Therefore a larger portion of southern New 
England, with the exception of the higher elevations and 
Cape/Islands, will have a good shot at hitting the 70 degree mark on 
Friday. 

Another moisture-starved shortwave and cold front moves overnight 
Friday. This will bring back temperatures into the low 60s for the 
weekend which is seasonable for late-October. Looking further ahead 
to the latter half of the weekend and next week, ensemble guidance 
shows agreement with a transition to a generally unsettled pattern 
which may feature periodic chances for showers. Confidence decreases 
with respect to the details such as timing.

remain elevated between 3 and 5 feet through the afternoon. As 
a result, Small Craft Advisories in effect tonight into Tuesday
