Area Forecast Discussion National Weather Service Boston/Norton MA 1018 AM EDT Sat Mar 28 2020

SYNOPSIS. Increasing cloud cover today as a warm front lifts in from the Great Lakes region. Rain will spread in from southwest to northeast late this afternoon and tonight. Rain will continue Sunday into Sunday evening as a secondary low develops just south of the region. Scattered showers are expected Monday and may even linger into part of Tuesday with cool temperatures and an abundance of clouds. A potential coastal storm may bring some rain or wet snow in the Wednesday through Friday time frame, but the system may also track far enough offshore for little if any impact.

NEAR TERM /UNTIL 6 PM THIS EVENING/. No major changes tot he forecast this morning. Increasing high clouds through the day, with lower bases arriving towards evening. Low level dry air firmly in place, with dew point depressions of 20-30 degrees. This will prevent much rain from reaching the ground for a while. Still expecting dew points to rise late today, with an increasing risk for rainfall across far western southern New England between 2-6 PM.

Brought temperatures back in line with observed trends. Also tweaked sky cover and rainfall timing based on latest high resolution guidance.

Previous Discussion .

* Dry and quiet weather for much of the region to start, but cloud cover will increase as a warm front lifts in. Precipitation spreading in from southwest to northeast during the afternoon and heading into the evening. Parts of Connecticut could see light precipitation move in before noon.

A mid level ridge axis will initially extend from southern New England northwestward into southern Quebec. The ridge will build offshore and into the Gulf of Maine. The surface high associated with the ridge will gradually build offshore. A neutrally tilted trough will be located over the Intermountain West. The trough will lift into the Upper Mississippi River Valley. A surface low will deepen as it lifts into the Mid and Upper Mississippi River Valley. The warm front associated with this system will lift across the central and eastern Great Lakes into southern New England.

Expect a dry first half of the day today due to high pressure. The high will slide offshore, which will allow a warm front to gradually lift into the region. Cloud cover will increase during the morning and showers will overspread western MA/CT by late afternoon. Good agreement amongst deterministic and ensemble guidance at this point in time. Winds shift to the south and there may be occasional gusts of 15-20 mph during the late morning and into the afternoon. High temperatures will be in the 50s.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SUNDAY/. Highlights

* Wet tonight through Sunday. Near to slightly cooler than normal temperatures on Sunday.

The trough located over the Upper Mississippi River Valley will lift northeastward into the central Great Lakes and southern Ontario. The trough will cutoff over the central Great Lakes. The surface low associated with it will lift into the central Great Lakes. The warm front associated with that system will gradually lift through southern New England.

There are hints that a secondary low develops around the triple point, which will be near Long Island. Strong southerly warm air advection will be present at 850 hPa, but this will be undercut as 925 hPa and surface winds shift to the southeast/east. There is good agreement amongst guidance in this occurring. This will limit how high temperatures get on Sunday. Suspect that the current forecast may still be too warm given the strength of the east/southeast flow. Highs are in the 40s at the moment. Will be wet with temperature near to below normals tonight through Sunday.

A strong low level jet will slide along and east of the south coast through Sunday. Best shot for strong gusts is along the east coast, Cape Cod and the Islands where gusts of 25-35 mph are possible. Think that the gusty winds will be limited across the interior as mixing will be limited due to cloud cover.

LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/. Highlights .

* Showers linger Sunday evening and there may even be a few embedded t-storms especially across RI/SE MA

* Cool temps Mon into Mon night with scattered showers and even some graupel/wet snow flakes possible too

* Cool temps on Tue with an abundance of clouds and a few left over showers possible

* Still need to watch a potential coastal storm Wed through Fri for some rain and/or wet snow if it tracks far enough north

Details .

Sunday night .

The secondary low pressure system near the south coast tracks near the Cape/Islands Sun evening. The moist onshore flow and modest southeast LLJ will continue to result in periods of showers/drizzle Sunday night, especially across eastern New England. In addition, the approach of the mid level dryslot will steepen mid level lapse rates and result in some elevated instability. This may result in a few embedded t-storms Sun evening with the best chance across RI/SE MA where the greatest amount of elevated instability and dynamics exist.

Monday and Monday night .

Strong upper level energy and its associated cold pool aloft will move east into New England. This combined with an inverted trough signal from offshore low pressure will set the stage for scattered showers. There may be enough instability for some graupel too with the cold air aloft. Lastly, temps might be cold enough for some snow flakes to mix in later Mon into Mon night. High temps will mainly be in the upper 40s to lower 50s. Lows Mon night will mainly be in the 30s.

Tuesday .

Upper level energy begins moves east of the region Tue, but some guidance indicates we still may have the resemblance of an inverted trough. So while we think it will be drier than Mon, still the risk for a few showers along with an abundance of clouds. Low level NNE flow should keep highs mainly in the 40s.

Wednesday through Friday .

Still a lot of uncertainty remains with this portion of the forecast. The guidance is in very good agreement in classic upstream blocking pattern /-NAO/. There is a lot of upper level energy around that results in the development for a coastal storm. While most 00z operational models show the system remaining far enough south and east for little if any impact, that is not set in stone. There is the potential for a track closer to the coast given the timing/amplification of vigorous shortwave energy. There are a few GEFS/EPS ensemble members that show a track further north along with the 00z Canadian model. This would bring the potential for rain or even wet snow given marginal thermal profiles. So in a nutshell, this is still a potential event 4-5 days in the future with a large spread in possible outcomes. We just need to keep all options on the table until the models become more stable.

AVIATION /14Z SATURDAY THROUGH WEDNESDAY/. Forecaster Confidence Levels .

Low - less than 30 percent. Moderate - 30 to 60 percent. High - greater than 60 percent.

Today . High confidence

VFR conditions through much of the day. Expect increasing mid to high clouds as the day progresses with a warm front lifting in. Best opportunity for MVFR ceilings is toward the evening push across western MA, CT. Winds shift to the S/SE with speeds generally less than 10 kts.

Saturday Night . High confidence in the trends. Moderate confidence in timing.

Conditions deteriorating to MVFR as ceilings lower and some localized IFR conditions may eventually develop across the interior. Potential for visibility reductions as well, but confidence is lower in visibility reduction. This will be most likely in areas of heavier precipitation. There is potential for IFR ceilings per the RAP/GLAMP guidance, but have not lowered to these levels at this point in time.

KBOS Terminal . High confidence in TAF.

KBDL Terminal . High confidence in TAF.

Outlook /Sunday Night through Wednesday/ .

Sunday Night: Mainly IFR, with local MVFR possible. Breezy. Chance SHRA, isolated TSRA, patchy FG.

Monday: MVFR/IFR conditions possible. Breezy. Chance SHRA, patchy BR.

Monday Night: MVFR/IFR conditions possible. Breezy. Chance SHRA, chance SHSN.

Tuesday: Mainly MVFR, with local IFR possible. Breezy. Slight chance SHRA.

Tuesday Night: Mainly MVFR, with areas IFR possible. Breezy. Slight chance SHRA, slight chance SHSN.

Wednesday: Mainly MVFR, with local IFR possible. Breezy. Chance RA.

MARINE. High pressure will slide offshore today and a warm front will lift in from the eastern Great Lakes. This will bring increasing cloud cover with rain spreading in from west to east this afternoon. Easterly winds will shift to the south/southeast. Wind speeds will generally be below 10 kts today.

Rain expected tonight through Sunday as the warm front lifts through and a secondary low develops along the south coast. It will be wet with rain and anticipate that there will be some visibility reduction as fog develops. Winds will gradually shift to the east tonight and Sunday and increase. On Sunday gusts will increase to 25- 30 kts along with seas building to 5-8 feet across the interior ocean waters, while the outer waters see waves build to 7-10 feet. Confidence has increased to issue a Small Craft Advisory across the majority of ocean waters through Sunday.

There is potential for isolated thunderstorms across the ocean waters Sunday evening.

Outlook /Sunday Night through Wednesday/ .

Sunday Night: Small Craft Advisory winds with gusts up to 30 kt. Rough seas up to 11 ft. Chance of rain showers, isolated thunderstorms, patchy fog. Local visibility 1 nm or less.

Monday: Winds less than 25 kt. Areas of rough seas. Chance of rain showers, patchy fog. Local visibility 1 to 3 nm.

Monday Night: Low risk for Small Craft Advisory winds with gusts up to 25 kt. Areas of rough seas. Chance of rain showers.

Tuesday: Low risk for Small Craft Advisory winds with gusts up to 25 kt. Rough seas up to 10 ft. Slight chance of rain showers.

Tuesday Night: Winds less than 25 kt. Areas of rough seas. Slight chance of rain showers.

Wednesday: Winds less than 25 kt. Areas of rough seas. Chance of rain.
