SYNOPSIS
Dry and partly sunny conditions persist this afternoon except for a slight chance of a band of isolated showers and an embedded thunderstorm this afternoon and evening. Tuesday will be the pick of the week with abundant sunshine and above normal temperatures.
Unsettled pattern mid to late in the week with cooler temperatures.
A few rumbles of thunder are possible, especially across the interior on Wednesday. Milder this weekend with drier weather, especially on Saturday.
NEAR TERM /UNTIL 6 AM TUESDAY MORNING/
As expected low/mid cloud cleared out for much of the region this afternoon allowing temperature to quickly jump from the 50s into the mid 70s for many. Sea breezes are keeping coastal locations much cooler in the 50s and low 60s. This is also keeping instability at bay along the coast while inland, mesoanalysis shows a few hundred J/kg of instability inland with up to 500 J/kg centered over northern RI/southeast MA where dewpoints are in the mid 60s.
This may come into play as a weak cold front sinks through the region later today, but the front looks to be delayed until early evening/early overnight hours which when instability will be diminished. So, while a few isolated showers and even a rumble of thunder are possible, odds are better that any particular location will remain dry. Overnight that high dewpoint air will lead to mild low temps and fog over the south and east coasts before winds behind the front shift to the NW and N, pushing drier air into the region.
SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/
Tuesday is the pick of the week as high pressure and a dry air mass will bring a sunny day with even warmer temperatures than we saw today. 925 mb temps increase from 15C today to 16-17C on Tuesday which will support high temperatures in the mid 70s (inland) and mid to upper 60s (coast). Winds will be light, becoming westerly in the afternoon. By afternoon high clouds are on the increase ahead of a warm front which approaches SNE overnight extending from an approaching surface low over the Great Lakes. Clouds will thicken and lower through the overnight hours ahead of widespread rain showers moving in from the west. There remains some uncertainty as to how quickly the showers move in, more likely holding off until near or just after 8am.
LONG TERM /WEDNESDAY THROUGH MONDAY/
Highlights
* Unsettled and cooler Wed through Fri.
* Trending drier on Sat with temps starting to rebound.
* Lots of uncertainty for Sun at this point, but the upward temperature trend may continue.
Wednesday...
Stuck under cyclonic flow through this period. A shortwave trough lifts from the central Great Lakes early on Wed into Upstate NY/northern New England by late in the day. A frontal boundary lifts toward and perhaps through portions of our region. Lot of uncertainty at this point which areas will be within the warm sector.
Still a fair amount of spread amongst guidance with how things exactly evolve through this period. Latest suite of guidance has trended a bit faster with bringing in the precip. Though there is spread in where the heaviest rains will fall at this point in time as there is spread in guidance with how convection evolves. At this point appears that the greatest risk for thunderstorms is across the interior, but especially across the Berkshires. This is where ensembles GEFS/GEPS/EPS indicate anywhere from low to mod (10-70 percent) probs of CAPE AOA 500 J/kg. The risk is highest across the Berkshires as even convective ensembles such NCAR C-ShiELD and MPAS guidance also highlighting this area as well. This does coincide with the GEPS/EPS guidance of total precip AOA 0.5" with low to mod probs (10-60 percent) whereas the GEFS is essentially nil for our area. Seems that the latest deterministic echoing the ensembles with the ECWMF/GEM showing more precip for our area than the GFS. Hard to say which is correct as we are a bit more removed from the shortwave, but there is roughly 1-1.5 inch PWATs in place. For now have stuck with NERFC QPF.
Still think that the latest SPC Day 3 Outlooks is reasonable given the setup. The deep layer shear will not be an issue with bulk shear of 40-70+ kts in the 0-6 km layer. The instability is more of a question as mentioned previously and where we warm sector. The low level lapse rates look quite pitiful at this point for our region.
However, mid level lapse rates are around 6-8 degrees Celsius during the day. Forecast soundings show much of our area being quite inverted or stable. This would limit activity to being more elevated in nature. Think that there could be some hail risk with this. This matches well with the CSU-MLP for Day 3. It does highlight a risk of winds out in far western MA/CT where there is potential for being more within the warm sector. Stay tuned for future updates.
Thursday and Friday...
Still unsettled through this timeframe as we remain under cyclonic flow. Another shortwave ejects into and perhaps through our region on Thu. The deeper trough over the Great Lakes is anticipated to start moving late Thu through Fri. The trough digs from the Great Lakes into the Mid Atlantic/southern New England on Fri. A frontal boundary will still be nearby or over the region during this timeframe. A few waves may ride along the front bringing us showers.
Guidance in a bit better agreement through this timeframe with a low sliding along the front that is nearby/south of our region. This will keep us unsettled with rain showers. Given the location of the front and low we will remain on the cool side with persistent onshore flow. Did nudge down our temps a bit from the NBM on Thu as it is much too warm with persistent onshore low. For now have stuck with the 50th percentile of guidance, but suspect we will need to lower further in future updates. Actually appears that the NBM is more dialed in on Fri with temps as again we've got persistent onshore flow. Highs on Thu range from the 50s to mid 60s whereas Fri we are generally in the 50s.
At this point it appears that showers will be around for a good portion of this timeframe. The heaviest activity appears to be later on Thu into early Fri as low pressure is deepening south of our area. Removed thunder chances at this point given the cool onshore flow and little if any instability. Ensembles indicating that 24 hr probs of QPF AOA 0.5 inches is low to mod (10-60 percent) generally southern New England region wide. Will also have a bit of an uptick in wind speeds/gusts out of the E/ENE during this period. Though the LLJ strength is a bit spread out amongst guidance from 10-20 kts to up to 30-40 kts. This coupled with the high astro tides will likely result in some issues across the eastern MA coast. See the coastal flooding section for more details.
Saturday and Sunday...
Still under cyclonic flow through this period. Though does appear that a shortwave ridge builds into the eastern Great Lakes/New England for Sat. The next wave/trough slides into the Great Lakes/Mid Atlantic for Sun. Drier on Sat as high pressure nudges in.
Another frontal system could slide in on Sun bringing us more showers.
Not a whole lot of focus on this period given the active weather for mid to late in the week. Have stuck with the NBM, which seems reasonable at this point. Temperatures will be on an upward trend through the weekend. High temps range from the mid 50s to the low 60s on Sat as we will still be under northerly flow. Winds shift to a southerly direction on Sun, which will result in temps continuing to trend upward. Highs generally in the 60s.
As mentioned there could be some showers spreading in on Sun, but there is a significant amount of timing, intensity and placement differences with the forcing. Think the NBM is fine at this point with chances of precip.
AVIATION /19Z MONDAY THROUGH SATURDAY/
Forecast Confidence Levels:
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
18Z TAF Update
This afternoon...high confidence.
Conditions have improved to VFR for most of the region. The exception is the Cape and islands where stubborn low clouds may hang on for the whole day. Mainly a dry day today, however widely scattered showers develop this afternoon and early evening. 10-20% chance of an isolated thunderstorm. Light WSW winds with local seabreezes along the eastern MA coast.
Tonight...Moderate Confidence
MVFR/IFR conditions fill back in across the interior and persist over the south coast, Cape, and Islands through about 06Z. Winds shift to the north after that time frame and allow ceilings to gradually improve to VFR by 09-12Z.
Tomorrow...High Confidence
VFR. Light northerly winds becoming light out of the west. Sea- breezes likely along the coast with very warm temps forecast over land.
Tomorrow night...Moderate Confidence.
Rain arrives to western terminals by 12z with VFR conditions throughout the night. Winds light and variable.
KBOS TAF...Moderate Confidence in TAF. Biggest question is if enough clouds fill back in to have the sea breeze flip back to west winds at 21z.
KBDL TAF...High Confidence in TAF.
Outlook /Wednesday through Saturday/...
Wednesday: MVFR/IFR conditions possible. Chance SHRA, isolated TSRA.
Wednesday Night: Mainly VFR, with local IFR possible. Chance SHRA, isolated TSRA.
Thursday: Mainly VFR, with local IFR possible. Breezy. SHRA likely.
Thursday Night: Mainly MVFR, with areas IFR possible. Breezy.

Tonight through Tomorrow night...High Confidence
Modest winds and seas continue tonight and tomorrow. Expect areas of fog over the coastal waters tonight as moisture increases from southerly winds. Fog should dissipate late tonight into tomorrow as a weak cold front ushers drier air over the coastal waters.
Outlook /Wednesday through Saturday/...
Wednesday: Winds less than 25 kt. Chance of rain showers, isolated thunderstorms. Local visibility 1 to 3 nm.
Wednesday Night: Winds less than 25 kt. Chance of rain showers, isolated thunderstorms.
Thursday: Winds less than 25 kt. Chance of rain showers.
Thursday Night through Friday: Winds less than 25 kt. Seas up to 5 ft. Rain showers likely.
Friday Night: Winds less than 25 kt. Seas up to 5 ft. Chance of rain showers.
Saturday: Winds less than 25 kt. Seas up to 5 ft. Slight chance of rain showers.
TIDES/COASTAL FLOODING
Coastal Flooding
High astro tides this week and concern becomes late Thu into Fri with potential frontal wave tracking south of New England, generating onshore flow into eastern MA. Magnitude of potential inundation and erosion will depend on strength and timing of surface low. Too early for specifics with any certainty, but given astro tides are already over 11 ft at Boston, it will only take a 1 ft storm surge and modest wave action to yield minor inundation and erosion. Stay tuned throughout the week for updated information.
