Synopsis for massachusetts and rhode island coastal waters - High pres builds into new england tonight through Friday. The high eventually shifts offshore this weekend. This will allow a warm front to lift in and bring showers late Saturday into early Sunday. The trailing cold front may slide through on Monday.

SYNOPSIS
Sprawling high pressure over northeast Ontario moves southeast over Southern New England through Friday, bringing clear skies and chilly nights tonight and Friday night. Unsettled pattern sets up for Sunday into early next week with shower chances.
Temperatures turn milder but there is a good deal of uncertainty as to how warm Sun/Mon are.
NEAR TERM /UNTIL 6 AM FRIDAY MORNING/
7 PM Update:
Sprawling high pressure ridging in from northeast ON bringing wall to wall sunshine, dry weather and light north winds (seabreezes near the coast). It is a bit cool out with current temps inland in the low to mid 50s, with cooler low/mid 40s near the coasts.
Center of high pressure will continue to progress SE into the Adirondacks tonight, and ridging to extend SE from it into Southern New England. Expect any seabreezes near shore to shift to land- breezes (southerlies) after sundown. Optimal radiational cooling is likely to begin tonight under clear skies, light to calm winds and very dry air in place. Thus low temperatures should reach subfreezing levels in many areas in the 20s to around 30, with lows 32-35F at Worcester and near Boston.
With forecast temps, the Freeze Watch was converted over to Freeze Warnings for northern CT, all of RI and eastern coastal and southeast MA, which are where the frost/freeze program is active.
Opted to keep things simple as some of the immediate city areas such as Boston, Hartford and Providence probably stay around or just above freezing, and the best chance at seeing freezes is in the outlying less urbanized areas. If you have planted crops in Southern New England, take the necessary protective actions to prevent frost or freeze related damage.
SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/
330 PM Update:
Friday and Friday Night:
Friday is essentially a carbon copy of today, as high pressure continues to slide southeastward into our southern outer waters.
After a chilly start, full sunshine and dry weather should allow temperatures to rise into the 50s to lower 60s, with mid 50s along the southern and eastern coasts as seabreezes get going. Will have a bit of a southerly flow develop later in the day as high moves to our southeast.
Friday night should again feature clear skies and favorable conditions for radiational cooling. Temps should project to be a couple degrees warmer than tonight's lows, utilizing a heavy dose of MOS guidance. That yields lows in the 30s, though a few areas which radiate well such as around I-495 in MA and NW MA could see subfreezing temps. The uncertainty in the forecast here revolves around winds, and it is possible that winds could be strong enough to preclude frost from developing. It's very close but it is possible that frost/freeze headlines could be needed again where the frost freeze program is active; but the wind speeds make it a tougher call.
LONG TERM /SATURDAY THROUGH THURSDAY/
Key Points...
* Remaining dry Saturday.
* Low chance for showers Saturday then again Tuesday through Thursday.
* Warming trend into next week, but uncertainty remains high
Saturday...
Upper level ridge and surface high pressure remains centered over the region through Saturday. With subsidence aloft and very dry mid level air, skies look to remain clear with very little clouds until late Saturday afternoon when high clouds ahead of a shortwave move in. This will help moderate day time temperatures into the mid to upper 60s Saturday. With a weak pressure gradient, local sea breezes will occur again Saturday morning. However, winds begin to increase out of the south Saturday afternoon, which could keep a true sea breeze from continuing along eastern coasts.
Upper level ridge axis passes to the east by Saturday night with some warm air advection ahead of the next shortwave trough. This will lead to increased cloud cover and and isolated to scattered showers. Lows stay warmer Saturday night in the upper 30s to low 40s.
Sunday and Monday
The center of the high pressure drops south to the Carolinas, but the upper level ridge axis continues to stretch north in SNE. Being at the top of the ridge axis, weak vort impulses, along with warm air advection aloft bring high clouds and low chances for isolated showers both Sunday and Monday. High temperatures Sunday and Monday will be very dependent on a back door cold front working in. Latest GFS and EURO is still bringing that back door cold front through Sunday and again Monday keeping temperatures in the low 60s for Eastern MA and RI, while western MA and CT stay warmer in the 70s.
However, if that cold front stays offshore Sunday, temperatures could easily top the mid to upper 70s. NBM guidance still remains significantly warmer then deterministic GFS and EURO guidance, so again used a blend of warmer NBM guidance with cooler CONSALL guidance. Temperatures Monday look to continue to warm for western MA and CT with a 30-40% chance highs top 80F per GEFS. Eastern MA and RI will still struggle to top 70F with the back door cold front stalled over SNE.
Tuesday through Thursday
Upper level ridge axis again moves offshore to the east, but this time, a weakening shortwave trough moves through the region, but details on exact timing and coverage of precip remains very uncertain. Given this is a week out, stuck with NBM for precip chances, which shows 30-40% chance for showers through the middle of next week. This seems reasonable given the weak forcing from the weakening trough. A cold front looks to move through behind the trough which could bring an isolated thunderstorms with it.
Southerly flow Tuesday should kick the back door cold front out, however guidance remains very spread out on highs temps with ensemble 25th-75th percentiles showing anywhere from the 50s to the 70s through Thursday.
