WHAT HAS CHANGED
While no significant changes have been made to the forecast, cannot rule out brief pop-up showers this afternoon, followed by widespread rainfall Saturday. While drier on Mother's Day, there remains a low chance of an afternoon shower or thunderstorm, though confidence remains low in terms of the areal coverage. Unsettled once again late Sunday night into Monday, followed with below normal temperatures early next week.
KEY MESSAGES
- No significant weather concerns are expected today, though a few brief afternoon showers are possible.
- Mother's Day weekend looks split, with widespread showers and cooler temperatures Saturday followed by somewhat warmer and drier conditions Sunday.
- Another round of unsettled weather is possible Sunday night into Monday, followed by a brief drying trend midweek with temperatures remaining below normal.
DISCUSSION
KEY MESSAGE 1...No significant weather concerns are expected today, though a few brief afternoon showers are possible.
While high pressure builds offshore of the Carolinas, a surface trough and fairly strong mid-level shortwave move through SNE this afternoon. Despite this forcing, the airmass remains considerably drier in the wake of Thursday morning's cold front passage. PWAT values are only around 0.4-0.6 inches per the 00z HRRR, indicating limited moisture availability. As a result, expect mainly diurnal driven showers this afternoon, with the greatest coverage across interior MA where PoPs range from 25-40 percent. Elsewhere, PoPs are generally 15-25 percent between roughly 2-8 PM. Not all locations will see rainfall, and any showers that do develop should be brief and light. Temperatures today will be seasonably cool, with highs running a few degrees below climatological normals in the upper 50s to lower 60s. Dry weather returns tonight, though clouds will gradually increase from west to east ahead of a more widespread rainfall event expected Saturday. Overnight lows fall into the 30s and 40s, coldest across interior MA where some locations dip into the mid 30s, while coastal areas remain milder in the mid 40s.
KEY MESSAGE 2...Mother's Day weekend looks split, with widespread showers and cooler temperatures Saturday followed by somewhat warmer and drier conditions Sunday.
Guidance continues to support unsettled conditions developing by late Saturday morning into the afternoon as an elevated warm front and accompanying 850mb shortwave move through SNE. Temperatures are somewhat below normal with highs in the upper 50s to lower 60s. Wind direction aloft are SW, this helps to increase humidity, PWATs too are increasing, 0.8-1.0 inches per the 00z HRRR, which is more or less the climatological normal for the first half of May, promotes widespread beneficial rainfall. 00z GEFS indicate a moderate probability of 50 percent for totals to exceed 0.5 inches. ECMWF ENS show something similar, with an axis of moderate-high probabilities (60-80 percent) of 0.5 inches across coastal RI and SE MA. This does align somewhat with HRRR, currently thinking widespread amounts of 0.3-0.6 inches with locally higher amounts possible in any convective showers. And at this time, there are no concerns with flooding.
Conditions improve heading into Sunday as subtle mid-level height rises support quieter and milder condition's for Mother's Day. While SW to WSW flow persists, a notably drier airmass is not expected to move into SNE. In fact, dew points climb into the low to mid 50s, making it feel somewhat more humid compared to the much drier conditions observed Thursday and Friday. Given the lingering moisture and embedded shortwave energy within the flow, cannot rule out a passing afternoon shower or thunderstorm as a few hundred J/kg of CAPE may develop. That said, Sunday does not appear to be a washout, though those with outdoor plans should remain weather aware. Afternoon highs rise into the low to mid 70s.
KEY MESSAGE 3...Another round of unsettled weather is possible Sunday night into Monday, followed by a brief drying trend midweek with temperatures remaining below normal.
Attention then turns to Sunday evening into early Monday as another mid-level trough and embedded shortwave energy moves through SNE.
This likely supports development of weak surface low pressure south of the region, bringing another round of rain during this timeframe.
While details regarding exact timing and rainfall amounts remain uncertain, the overall signal for unsettled conditions is increasing. A brief drying trend is possible Tuesday into Wednesday as high pressure attempts to build S and W of the region.
Temperatures trend back below climatological normal early next week, with highs mainly in the 50s Monday and upper 50s to lower 60s Tuesday and Wednesday.

Tonight...High confidence.
VFR. Mid-level clouds increasing W to E overnight. WSW to SW wind less than 5 kt.
Saturday...High confidence.
Low-end VFR early, MVFR by late morning into early afternoon with widespread RA developing. Cannot rule out embedded thunder at this time, terminals along the southern coast may have the greatest chance for rumbles. S wind increasing into the afternoon, gusts up to 20-25 kt possible.
KBOS Terminal...High confidence in TAF.
KBDL Terminal...High confidence in TAF.
Outlook /Saturday Night through Tuesday/...
Saturday Night: Mainly VFR, with local IFR possible. Breezy.
Chance SHRA.
Sunday: VFR. Breezy. Slight chance SHRA.
Sunday Night: Mainly VFR, with local IFR possible. Chance SHRA.
Monday: Mainly VFR, with local IFR possible. SHRA likely.
Monday Night: Mainly VFR, with local MVFR possible. Slight chance SHRA.

MARINE
Forecaster Confidence Levels...
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
Through Saturday...High confidence.
A weak frontal passage this afternoon produce SW gusts 20 to 25 kt for the nearshore waters off the south coast of MA & RI, followed by gust less than 15 kt tonight. Seas today into tonight are 2 to 4 ft.
An area of low pressure tracks well inland on Saturday, a warm front lifting north during the day and periods of rain and embedded thunderstorms. A wind shift to the S-SSE and increasing wind speeds 15 to 20 kt and gust 25+ kt. Seas build from S to N as well throughout the day 4 to 7 ft. Due to these conditions, likely will need a Small Craft Advisory come Saturday afternoon.
Outlook /Saturday Night through Tuesday/...
Saturday Night: Low risk for Small Craft Advisory winds with gusts up to 25 kt. Seas up to 5 ft. Rain showers, isolated thunderstorms, patchy fog.
Sunday: Winds less than 25 kt. Areas of seas approaching 5 ft.
Sunday Night: Winds less than 25 kt. Seas locally approaching 5 ft. Chance of rain showers.
