SYNOPSIS. In the wake of an Arctic cold front widely scattered snow showers are possible late this evening and overnight. Winds ramp up prompting a Wind Advisory for all of southern New England through early Tuesday afternoon. Additionally, temperatures drop well below normal and are accompanied by sub-zero wind chills for Tuesday morning. A brief warmup expected on Wednesday with above normal temperatures, then a return to somewhat colder weather late in the week through the weekend, but mainly dry condition should prevail.

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/.

Rain showers continue to shift towards the east with the back edge of the showers exiting eastern Massachusetts between 5 PM and 7 PM. High-res guidance brings widely scattered snow showers into northern Massachusetts between 03z-06z. The signal for snow squall parameter isn't as robust, thus we aren't anticipating any squall-like conditions. HRRR and NAM 3KM show streamers of snow moving across areas north of the Mass Pike and fizzle out as they shift towards the coast. Since these snow showers will be widely scattered we don't anticipate any significant issues on the roadways - outside of a brief period of reduced visibility.

On the backside of this cold front our wind direction veers from the south to the northwest. Aloft, a 700mb trough moves across southern New England late this evening through early Tuesday morning. Looking at BUFKIT soundings we should be able to mix down rather gusty winds to the surface - up to 50 MPH away from the coast and near 60 MPH over the waters. Wind Advisories still stand for all of Massachusetts, Connecticut, and Rhode Island through Tuesday afternoon. It's worth to mention areas across the higher terrain of Worcester County, eastern slopes of the Berkshires, out the outer most areas of the Cape could see isolated wind gusts as high as 60 MPH. Over the water we do anticipate winds to gust between 60 and 65 MPH - because of this we did replace our Gale Warnings with Storm Warnings - the only exceptions are Narragansett Bay and Boston Harbor.

Finally, it's a rather cold night with temperatures ranging from the upper teens at the coast to near zero across the interior. Our blustery northwest wind is driving down our feels like temperatures to zero at the coast and -20F across the interior. Because of this we did extend our Wind Chill Advisory to now include all of Franklin County, northern Worcester County, and northern Middlesex Counties.

SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/.

Tuesday: An area of weakening high pressures will slide across the southern Ohio Valley, this pushes a surface low out into the Saint Lawrence Gulf. Winds will ease during the first half of the day though it will remain rather chilly with highs in the 20s to lower 30s at the coast.

Tuesday Night: The weakening high pressure slides south and lowering pressure to the north, that will result in increasing clouds overnight. Winds aloft will shift from NW to SW and help usher in slightly warmer temperatures. This coupled with the cloud cover should yield overnight lows in the upper teens across the interior to the low 30s at the coast.

LONG TERM /WEDNESDAY THROUGH MONDAY/. Highlights .

* Mild and dry Wed

* Turning colder for the end of the week into the weekend with below normal temps

* Mainly dry through the period

Overview .

Developing -AO/-NAO pattern through the end of the week and into the weekend as Greenland block sets up. Piece of TPV will locked in across eastern Canada with troughiness over the NE and New Eng. Result will be a trend toward colder temps averaging below normal from Thu through the weekend with Fri/Sat likely the coldest days of the period. This will be preceded by a relatively mild day on Wed with above normal temps.

Precip wise, it looks like a rather quiet period with mainly dry conditions right through the weekend and into early next week. There are multiple shortwaves rotating around the vortex in eastern Canada but moisture is limited and outside of a few brief flurries/snow showers, expect mainly dry conditions. Weekend ocean storm is expected to pass well SE of New Eng and not pose a risk.

There is decreasing forecast confidence as we head toward the end of the weekend into early next week on how quickly the pattern breaks down which impacts temp forecast. GFS is quicker than ECMWF lifting out the trough and building the SE ridge which brings milder temps to the region Sun/Mon. We leaned toward slower ECMWF solution as GFS typically has a progressive bias, so we have temps remaining below normal. It does appear pattern change eventually takes place during next week with a transition to +AO/+NAO/-PNA and milder weather.

AVIATION /20Z MONDAY THROUGH SATURDAY/. Forecaster Confidence Levels.

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

This Afternoon . High confidence.

IFR to LIFR conditions improving to VFR by late afternoon as precipitation tapers off from west to east. Winds shifting from the S/SE to the W/NW as a cold front moves through. Gusts of 30-40 kts developing during the late afternoon.

Tonight . High confidence.

VFR with strong WNW to NW gusts of 35-45 kts. There may be a few isolated 50 kt gusts as well as GFS/NAM BUFKIT soundings indicate. Could see brief MVFR/IFR snow showers/squalls passing through, we do expect coverage to be widely scattered at best.

Tuesday . High confidence.

VFR with gusty WNW to NW winds to start. Expecting gusts of 30-45 kts to start. Winds and gusts diminishing during the afternoon. Should see gusts falling to 15-30 kts.

KBOS TAF . High confidence in trends. Expect a period of IFR/LIFR into the AM push, improving to VFR in the afternoon.

KBDL TAF . High confidence in trends. Expect a period of IFR/LIFR into the AM push, improving to VFR in the afternoon.

Outlook /Wednesday through Saturday/ .

VFR. Breezy.

MARINE.

We've upgraded all our waters to Storm Warnings for gusts between 60 and 65 MPH, the only exception are Narragansett Bay and Boston Harbor where Gale Warnings are still in effect. We expect these gusty winds to persist through early Tuesday afternoon. On top of this have widespread moderate freezing spray still expected with an arctic airmass moving in. The Freezing Spray Advisory previously issued into for tonight into Tuesday morning still looks good.

Outlook /Wednesday through Saturday/ .

Wednesday: Low risk for Small Craft Advisory winds with gusts up to 25 kt. Local rough seas.

Wednesday Night: Winds less than 25 kt. Seas locally approaching 5 ft.

Thursday: Low risk for Small Craft Advisory winds with gusts up to 25 kt. Local rough seas.

Thursday Night through Friday: Moderate risk for Small Craft Advisory winds with gusts up to 25 kt. Areas of rough seas. Chance of freezing spray.

Friday Night: Moderate risk for Small Craft Advisory winds with gusts up to 25 kt. Areas of rough seas.

Saturday: Winds less than 25 kt. Seas up to 5 ft.
