Synopsis for the long island and connecticut coastal waters - High pressure extending south along the new england coast and into our our area will remain nearly stationary into Saturday. A cold front then slowly approaches from the west on Sunday and moves across the area Sunday night into Monday. The boundary likely stalls to our south Monday afternoon through Tuesday before returning as a warm front Wednesday. A series of frontal waves may impact the area to end the week.

SYNOPSIS
High pressure brings dry weather with cooler onshore breezes through Saturday. A slow-moving frontal boundary brings clouds and rain showers on Sunday into early Monday, along with a period of cooler high temperatures. Though clouds and off and on showers may linger in southeast New England near vicinity of the slowing front, drier weather prevails for most of interior Southern New England. Turning warmer on Tuesday with abundant sunshine, and though temperatures will be significantly cooler near the coast, interior areas could see high temperatures reach near 80 degrees. Our next chance for rain is around midweek.
NEAR TERM /UNTIL 6 AM SATURDAY MORNING/
Good amount of wind shear visible on the satellite this afternoon with mid level clouds moving NE to SW and upper level cirrus moving NW to SE this afternoon. As for those mid clouds, the May sun is helping to increase our breaks of sun but partly cloudy is about the best we can hope for in much of southern New England for the rest of the day. By the overnight hours we'll see some marginal clearing of both mid and high clouds, especially after midnight, but fully clear skies aren't expected. Even so, given the high overhead and calm winds, did lower temps a but to account for some potential to radiate. Lows bottom in the low to mid 40s; right around average for early May.
SHORT TERM /6 AM SATURDAY MORNING THROUGH 6 PM SATURDAY/
High pressure nudges further south into New England from Nova Scotia bringing continued quiet weather for the first half of the weekend.
This means continued cool, moist onshore flow from the northeast so low clouds will be moving in from the northeast while high clouds move in from the southwest. High temperatures won't be too different than Friday, with the warmest spot (the CT valley) in the upper 60s and the coolest spot (eastern MA) in the mid 50s. Cloudcover continues to increase overnight as deeper moisture (PWATs over 1 inch) move into western SNE on SW flow ahead of the approaching system. However, rain should hold off until after 8am.
LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/
Highlights:
* Cloudy, cooler with rain on Sunday into early Mon, with continued lighter showers on Mon for southeast New England.
* Dry and turning mild on Tue, though cooler onshore flow near the coasts. Spot 80s in the CT Valley?
* Next chance for rains around midweek (Wed/Thu), though still unclear which day has the higher rain chances.
Details:
Sunday and Monday:
The 12z suite of guidance continues to come into better congruence regarding our next chance for steadier light rains associated with a passing frontal boundary and a rather disorganized 500 mb trough.
Chances for rain increase during the morning in most areas, with the period of greatest rain chances focused during the Sunday afternoon to early Monday morning period as the frontal boundary slowly shifts eastward. With the front becoming parallel to the 500 mb flow with time as we move into the early Monday period, expect lingering rain showers during the morning hrs along the RI/MA South Coast, Cape Cod and the Islands. Further north and west, we should see dry weather but with a mix of clouds and sun. Overall not a soaking rain, but enough to likely put a damper on outdoor plans for many on Sunday, with rain showers lingering into Monday for the southeast New England coastal areas. To that end, model-ensemble probabilistic QPF assessment shows high (70-90%) probs of 24 hr rain totals over a tenth of an inch, but lower to moderate (25-50%) probs for rain amts at or over a half inch. Official forecast has rain amts around a quarter to third of an inch.
Expect Sunday to be a cooler day with cloud cover and rains around, with narrower diurnal range in high and low temps. Highs Sunday in the mid 50s, and lows in the upper 40s to near 50. High temps are more challenging on Monday with more clouds south of the Mass Pike and especially near southern coast, with some sunny breaks further north. HIghs along the southern coast probably struggle to reach 60, but you don't have to go much further inland before highs reach into the low to mid 70s; with lows in the mid 40s to low 50s.
Tuesday:
High pressure over interior northern New England governs weather conditions into Southern New England Tuesday, supplying dry weather and mostly sunny conditions. An early look at model forecast soundings in interior MA/CT show potential for temperatures to overachieve guidance with progged deep mixing; with 850 mb temps around +7 to nearly +10C, highs could reach around 80 degrees in the CT Valley with readings well into the 70s eastward into RI and into the MA coastal plain. Northeast flow near the coast will keep temps several degrees cooler than well inland though, in the mid to upper 60s. Very difficult to show that level of granular detail given model-resolution limitations at this forecast time horizon and utilized some of the bias-corrected temperature fields given a similar regime. Did note NBM was advertising some low PoPs in this period for spot showers, but feel this is pretty overdone given progged mixing.
Wednesday and Thursday:
Though this period offers the next best chance for rain associated with an elongated warm front from low pressure over the Plains states, there is more uncertainty in timing when chances are greatest. Really will need those uncertainties to become more in clearer focus before delving into specifics. Didn't make too many adjustments to NBM in this period, except capped PoPs at the higher end of Chance range (40-50%) given stated timing uncertainties.
AVIATION /19Z FRIDAY THROUGH WEDNESDAY/
Forecast Confidence Levels:
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
Through 00Z...High confidence in trends, moderate in exact timing.
VFR across the CT River Valley, but still working on eroding the MVFR/borderline VFR conditions across central MA/RI into eastern MA. Should see these ceilings continue to lift/scatter out by roughly 19-21Z. This should take the longest across the Cape terminals, though think ACK remains MVFR through the forecast with onshore flow.
Tonight...Moderate confidence.
VFR conditions to start with light and variable winds. There is a possibility for MVFR stratus to spread back in with enough onshore flow aloft. Timing wise think it would be after 06Z.
Could see patchy fog across the typical prone areas in the Merrimack Valley, but have only hinted at for now.
Tomorrow...Moderate confidence.
Any lingering MVFR may improve to VFR for much of the day. Some uncertainty here given we are still stuck in persistent onshore easterly flow at 5-10 kts. Confidence higher for VFR away from eastern MA coastline.
KBOS TAF...High confidence this afternoon. Lowers to moderate tonight.
Improving to VFR by 19Z with NE to E winds. Winds light and variable tonight with enough onshore flow aloft that MVFR stratus could spread back in roughly 04-06Z. Could improve to VFR as boundary layer mixes roughly 13-15Z, but uncertain on this given the onshore wind component.
KBDL TAF...High confidence.
VFR through the forecast. Could see some borderline MVFR ceilings spread in 02-04Z tonight.
Outlook /Saturday Night through Wednesday/...
Saturday Night: Mainly VFR, with local IFR possible.
Sunday: Mainly VFR, with local IFR possible. Chance SHRA.
Sunday Night: MVFR/IFR conditions possible. SHRA.
Monday: Mainly VFR, with local IFR possible. Slight chance SHRA.

This evening through Saturday night...
