SYNOPSIS. Dry and quiet weather through much of the week as temperatures trend downward through Thursday. Expect cloudy conditions through tonight across the region. Any ocean effect rain showers will change to snow showers tonight across Cape Cod and Nantucket, then will taper off early Wednesday morning. High pressure over Ontario builds toward the region Wed and Thu resulting in dry and seasonably cold weather. The high moves offshore Friday with temperatures moderating. Still watching for the potential for a coastal storm which may impact the region Saturday/Sat night, though it remains far from a certainty. Dry, blustery and colder weather likely follows Sunday into Monday.

NEAR TERM /UNTIL 6 PM THIS EVENING/.

130 PM Update .

Cloudy conditions continue across the region early this afternoon. Bands of ocean effect rain showers remain off the east coast of Massachusetts, occasionally moving across outer Cape Cod though they are light. The dry cold front, moving S across the region, will push off the S coast during this afternoon.

A few thin bands of showers were also crossing portions of central Mass at around 18Z, but most of this precip was not reaching the ground. The only report of light snow occurred at KORE late this morning. Most of the precip evaporated before reaching the ground due to dry air in the lower levels, with dewpoint depressions on the order of 9 to 17 degrees across inland areas. May see more organized bands of showers develop across the eastern waters late this afternoon into early evening.

Temps at 18Z were running in the mid to upper 30s away from the coast to as high as the lower 40s across portions of the coastal plain. Northerly winds at 5-10 kt with some gusts approaching 20 kt are making it feel a bit cooler.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM WEDNESDAY/.

The cyclonic flow persists through the short term. Good agreement amongst guidance that a shortwave digs from the central/eastern Great Lakes to south of southern New England by Wednesday morning. A ridge will build into the central Great Lakes on Wednesday.

Tonight .

As the shortwave exits, expect drier air to advect in behind the trough. Flow will still be north/north northwesterly, so still may see scattered ocean effect rain showers change to snow showers through around 09Z with the best lift coinciding with the high RH wrt ice. After 09Z, should see drier air advect in and lessen the chances of snow showers. There is some disagreement in how quickly things dry out as the ARW/NMM and GEM linger the ocean effect snow into Wednesday morning. Think that this is too long per the NAM/NAMNest and GFS, but is something to keep an eye on. Expect this to be the timeframe where the snowfall accumulates. Expect anywhere from a dusting to an inch of accumulation on Cape Cod.

Low temperatures range from the mid teens across the eastern Berkshires to the low 30s across the outer Cape.

Wednesday .

Decreasing cloud cover as high pressure nudges into the region. Temperatures still trending downward due to northerly cold air advection. High temperatures will generally be in the 30s across southern New England.

LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/. Highlights .

* Mainly dry Wed night into Fri with seasonably cold temps but rebounding above normal by Fri

* Still monitoring for a potential storm Saturday/Sat night, but forecast confidence remains very low on details

Details .

Wed night/Thursday .

Potent closed low tracks north to south from Quebec across the Canadian Maritimes this period and spreads a shallow colder airmass across New England with 925 mb temps falling to about -8C to -10C. This will result in a chilly night with low temps at or slightly colder than normal. This colder air being delivered on northeast flow and streaming across warmer than normal ocean will yield steep low level lapse rates and lots of ocean effect clouds into eastern MA and perhaps a few snow showers or flurries across Cape Cod and coastal Plymouth county. Remaining chilly Thu but temps near seasonable with highs in the low to mid 30s. It will be fairly pleasant by late Jan standards with mostly sunny conditions (although ocean effect clouds may linger over southeast MA trapped beneath subsidence inversion) and light winds with 1025 mb high pres overhead.

Friday .

Dry weather with short wave ridging building across southern New England. Light WSW winds with high pressure drifting offshore and 925 mb temps moderating to about -3C should support highs Fri afternoon into the lower 40s (upper 30s hilly terrain) along with sunshine and light winds. Probably pick of the week.

The Weekend .

Still lots of uncertainty among 00z deterministic and ensemble guidance regarding track of coastal storm Sat/Sat night. 00z GFS and UKMET have trended closer to the coast while 00z ECMWF has a lead wave Fri night/Sat delivering some snow/rain to southern New England. Then, the EC has a trailing much stronger short wave digging from the OH Valley to the Mid Atlc Sat night with secondary cyclogenesis well offshore.

00z EC ensembles continue to display large spread in low tracks and many members supporting surface pressures in the 980s mb range. Thus there is the potential for a potent system, but track and when phasing occurs remain highly uncertain. In addition, lack of cold air over southern New England preceding the storm yields the possibility of ptype issues especially if this new northwest/closer to the coast trend continues.

Short wave energy that will initiate cyclogenesis/storm development is currently over the northern Pacific with jet energy emerging from a complex 3 separate closed low configuration from the Gulf of AK to the Aleutians. How this energy ejects out of this complex configuration and then tracks across the CONUS screams high uncertainty. Thus, will just have to see how trends evolve over the next few days.

For what it's worth, the past two runs from the EC ensembles have about 20% of its members supporting 6+ inches of snow for the I-95 corridor. Conversely, the remainder of the members are misses with phasing too late and other members with rain/snow line farther northwest focusing heavy snow threat over NY state into northern-central New England. Thus at this time range all possible outcomes remain in play.

A drying trend should follow Sunday behind the departing cyclone.

Monday:

Ensembles suggest dry northwest flow with temps at or slightly above normal.

AVIATION /19Z TUESDAY THROUGH SUNDAY/. Forecaster Confidence Levels .

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

18Z Update .

Through 00Z .

VFR conditions at most locations, with CIGS mainly from 3500 to 5000 ft. However, a few terminals have MVFR CIGS such as KORH and close at KIJD at 3100 ft. CIGS at a few more interior terminals may lower to 2500-3000 at times through the remainder of the afternoon, then CIGS may lower to MVFR toward nightfall across the outer Cape. Scattered ocean effect rain showers may push into the mid and outer Cape and Nantucket late this afternoon with local VSBYS reduced to around 3SM.

Tonight .

VFR across most locations, but may see MVFR CIGS across the eastern slopes of the Berkshires and eastern coastal MA. Best chance for MVFR ceilings is across Cape Cod and Nantucket where scattered ocean effect rain and/or snow showers may fall. Best opportunity for snow showers is at HYA and ACK. Drier air will move in across the interior, so conditions should improve there. However, the snow bands may linger into daybreak across the mid and outer Cape into Nantucket.

KBOS Terminal . High confidence in TAF through 00Z, then moderate confidence as MVFR ceilings may move in along the E coast and develop across N central/W Mass.

KBDL Terminal . High confidence in TAF.

Outlook /Wednesday Night through Saturday/ .

Wednesday Night: VFR. Breezy.

Thursday through Friday: VFR.

Friday Night: Mainly VFR, with local IFR possible. Slight chance SN.

Saturday: MVFR/IFR conditions possible. Chance RA, chance SN.

MARINE.

Short Term /through Wednesday/ . High confidence.

Through 00Z . N-NW winds 10 to 15 kt with gusts up to 20 kt. Scattered rain showers across the eastern waters from Nantucket to Cape Cod to E of Cape Ann, but dry elsewhere. Seas 4 ft or less. Visibility as low as 3 miles in any showers. Good visibility elsewhere.

Tonight . Winds becoming N 10 to 15 kt. Seas 3 to 4 ft. Scattered rain/snow showers across the eastern waters from east of Boston Harbor to near and east of Cape Cod and Nantucket. Visibility of 1 to 3 miles in precipitation. Good visibility elsewhere.

Wednesday . NW winds 10 to 15 kt gusts increasing to 15 to 20 kts during the afternoon. Seas 3 to 4 ft approaching 5 ft across the eastern waters. Good visibility.

Outlook /Wednesday Night through Saturday/ .

Wednesday Night through Thursday: Winds less than 25 kt. Local rough seas.

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

Friday: Winds less than 25 kt.
