SYNOPSIS

Increasing chances for showers and thunderstorms ahead of an approaching cold front, mainly late this afternoon into this evening. This cold front moves offshore early Tuesday, with decreasing clouds and drier weather conditions. Generally dry from mid week into the weekend with more seasonable temperatures. Cannot rule out a few hit or miss showers later on Wednesday into Thursday.

NEAR TERM /THROUGH TONIGHT/

Regional radar data showed that the last few runs of the HRRR were too aggressive in triggering convection across our region early this morning. Based the forecast for next few hours off the 00Z HRRR, as well as the latest RAP and NationalBlend runs.
Thinking there is a risk for at last some showers as a decaying convective band approaches from eastern PA towards daybreak.
Even lower risk for thunderstorms, but not impossible.

Issued a Dense Fog Advisory for RI and the south coast of MA.

Low pressure is expected to move across the Great Lakes into southern Canada today. The warm front associated with this low will struggle to move much north of our region. Noticeably cooler today, but still just as humid. Most of southern New England should see less than one quarter inch of rainfall today, where it rains at all. There is a risk for locally heavier rainfall from the stronger showers and less frequent thunderstorms.

Instability will be tough to generate today due to the stratus and fog which will take time and energy to dissipate. Overall MUCAPE values should remain less than 500-700 J/kg today, meaning there is not much of a severe weather threat, other than locally heavy rainfall.

SHORT TERM /TUESDAY/

The cold front associated with a low pressure in southern Canada should move into our region some time tonight into Tuesday.
Timing this front has been a challenge, as many different possibilities have been presented over the past few days.
Consensus timing now has this front arriving after midnight tonight, but still somewhere just east of southern New England by Tuesday evening. We should not see the humidity diminish until this front passes completely by our region. Looking at another round of stratus and fog tonight.

The heaviest and most widespread rainfall is expected this evening into tonight. Not as much forcing for Tuesday, so thinking we can get through most of the day without rainfall.

Above normal temperatures continue.

LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/

Highlights

* Dry for much of Wed with more seasonable temps. Could have spotty showers across the interior during the afternoon/evening.

* Shot for more widespread rain Wed Night into Thu, but there is a lot of uncertainty at this point.

* Overall looking pleasant Fri through the weekend with dry conditions. Temps near seasonable levels.

Tuesday Night through Wednesday...

Stuck in blocky cyclonic flow through this period. Will have a trough over Upstate NY and a shortwave over the western Great Lakes to start. The first wave lifts northeastward, while the shortwave digs into the OH Valley. The shortwave begins interacting with the larger trough over the eastern Great Lakes/Mid Atlantic by late in the day. A cold front slides through Tue Night into early Wed. Could see a secondary cold front or surface trough sliding in late in the day.

Anticipating dry and quiet weather through the vast majority of this period. Does appear that there will be an opportunity for spotty showers Wed afternoon into the evening as the surface trough/secondary cold front is sliding in. Some uncertainty on this as winds will be W to WNW through the period. Should have a roughly 15-30 kt LLJ sliding through. This should aid in keeping us well mixed and drying things out as seen in the 1000-850 hPa RH. Moisture values really not that impressive with meh PWATs at +/- 1 STD above/below NAEFS/EPS model climo. The result are PWATs roughly of 0.75 to 0.85 inches. Dialed back our precip chances to slight for much of the period, though western areas could see some scattered activity push in toward the evening.

Only other adjustment made during this timeframe was to increase temperatures given the W/WNW flow. This should result in downsloping with 925 hPa temps of 9-15 degrees Celsius. Opted to bump us up to the 75th percentile of guidance. Highs will generally be in the 70s.

Wednesday Night through Thursday...

Still in cyclonic flow. Will have that second shortwave/trough over the Mid Atlantic lifting toward/through southern New England by early Thu. It continues lifting toward Nova Scotia by late Thu, though could pivot across the Cape on Thu. A cold front will be lingering nearby. We could have an area of low pressure ride along the front, though there is a fair amount of uncertainty.

Big question mark during this period appears to be when the trough lifts toward us late Wed and how negatively tilted it becomes. Guidance is split with the GFS lifting the trough into the Gulf of ME before it becomes negatively tilted, while the international guidance as a whole does it as it lifts into/just south of Long Island. This also results in the trough continuing to slowly lift through on Thu vs the more progressive GFS. The international guidance solutions put a baggy trough or perhaps cutoff nearby southern New England heading into Thu at 700 hPa, whereas the GFS does not. This cutoff solution would bring the risk for heavier precip.

Despite these details am not overly amped up at this point about the rain risk late Wed into Thu. NAEFS/EPS guidance show PWATs of 1 STD below model climo. Values anticipated to be generally around 0.75 to perhaps 1 inch. So, not a whole lot of moisture to work with. Though if we can get the trough nearby southern New England we could really squeeze out the moisture available. Should also have some roughly 1.5-2.5 km warm cloud layer depths. Despite not being amped up about it there is some ensemble hints at more widespread QPF, especially across the south coast. The GEFS like the GFS is the least amped up with only low probs (10 percent) of 24 hr QPF AOA 0.5 inches. The GEPS/EPS show low to moderate probs (10-50 percent) of 24 hr QPF AOA 0.5 inches. Both the GEPS/EPS also showing some low probs of 24 hr QPF AOA 1 inch. So will be something to keep an eye on.
Though at this point not anticipating to have much instability.
High temperatures on Thursday will be right around seasonable levels.

Friday through the weekend...

Cyclonic flow continues through much of the period. A cutoff swings through much of New England on Fri as a ridge builds into the western/central Great Lakes. The ridge axis builds toward the eastern Great Lakes by late Sat and Sun. High pressure begins nudging in on Fri, but should build in for the weekend.

Generally am anticipating dry and quiet weather late in the week and through the weekend with high pressure in control. Do wonder if the cutoff will be close enough on Fri that we still can see some spotty showers, but for now think NBM slight chances suffice. Dry through the weekend with temperatures still around seasonable levels.

AVIATION /12Z MONDAY THROUGH FRIDAY/

Forecast Confidence Levels:

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

Today...High confidence in trends. Moderate confidence in timing.

IFR to VLIFR conditions today. Generally dry other than stratus and drizzle, outside of western areas where spotty showers developing. More robust line of rain associated with a cold front develops after 19-21Z. Some embedded TSRA possible with this round and have handled with PROB30 at all terminals. Winds remain E to SE, may gust as high as 20kt this afternoon.

Tonight...Moderate Confidence.

Another round of stratus and fog. Rain will come to an end between 05-09Z, yielding improving conditions with improvement from IFR to MVFR/VFR around sunrise. Winds shift from the SE to the S/SW, gusting to 20kt, behind a frontal passage.

Tuesday...Moderate Confidence.

A cold front continues to move across our region, but likely stalls some where just offshore. Improving to VFR toward mid to late AM. Winds out of the SW/W at 5-10 kts and could have some 15-20 kt gusts during the afternoon.

KBOS TAF...High confidence in TAF trends, moderate in timing.

VLIFR to start with stratus/fog. Thinking we see improvement roughly 14-17Z to MVFR visby, but IFR stratus persists. Dry for much of the day other than spotty drizzle. Will see steadier showers moving in approx 23-01Z. Could have some embedded thunder and have handled with a PROB30 for tonight. Should rapidly improve to MVFR/VFR Tue AM and wind shift to the SW.

KBDL TAF...High confidence in TAF trends, moderate in timing.

Will have IFR conditions today with SE winds increasing. Should see gusty 20-25 kt winds toward this evening as showers spread in. Rainfall may be heavy at times tonight along with embedded thunder. Have handled the embedded thunder with a PROB30. Winds turning S/SW late and rapidly improving to MVFR/VFR toward Tue AM.

Outlook /Tuesday Night through Friday/...

Tuesday Night: VFR. Breezy.

Wednesday: VFR. Slight chance SHRA.

Wednesday Night through Thursday: VFR. Chance SHRA.

Thursday Night through Friday: VFR. Slight chance SHRA.
