SYNOPSIS. Skies will remain cloudy through tonight. With cold northerly winds, scattered ocean effect rain showers will pass across the mid and outer Cape to Nantucket. As temperatures fall tonight, the rain will change over to light snow showers with some light accumulations possible into early Wednesday morning before tapering off. Dry, quiet conditions with near normal temperatures are expected for the remainder of Wednesday and into Thursday. This high moves offshore Friday with temperatures moderating. Still watching a potential coastal storm which may impact our region Saturday/Sat night. Dry, blustery and colder weather likely follows Sunday into Monday.
NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/. Through 00Z .
Will continue to see cloudy skies across the region in the overall cyclonic flow across the northeast. Light precip bands also continue to move S-SE across the eastern waters near and E of Cape Ann and Cape Cod. Some light precip is also moving across central Mass into N RI, though it remains dry in the lower levels so not expecting any precip to reach the ground there or, if it does, it will be brief and very light.
May see the light rain band E of the outer Cape begin to expand westward this evening. Have mentioned scattered rain showers possibly reaching Chatham to Wellfleet and Truro by around 00Z.
Tonight .
The majority of the model suite, especially the high res short range models, have continued to signal the ocean effect band to become better organized this evening E of Cape Cod, then shift southwestward through around midnight or so. The rain early this evening will change over to snow showers as temps fall back to the lower 30s.
The best chance for any light snow accumulations will occur across the outer arm of the Cape, but not expecting much more than an inch in isolated spots, if that. Possible to see a dusting of snow as far W as Hyannis. Also noting some possible snow showers developing across the E slopes of the Berkshires as another weak mid level short wave moves across. Should see any precip taper off after 06Z- 08Z, though might linger across the outer Cape until around daybreak.
Across the remainder of the interior, where dry conditions are expected, skies will begin to clear after midnight. Northerly winds will continue to 5-10 mph.
SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/. Wednesday and Wednesday night .
Clouds across east coastal areas will shift SE as high pressure slowly builds out of southern Ontario to central Quebec during Wednesday. Overall, expect a mostly sunny day. Expect high temps to be close to seasonal levels for late January, mainly from 30 to 35 across the higher terrain to the upper 30s to near 40 across the coastal plain. It will feel chilly, though, as north winds at 10-15 kt will bring wind chill values down to the 20s.
The high will remain across Quebec Wednesday night, but any leftover pressure gradient will relax. So, expect mainly clear skies across most areas with light northerly winds. Some clouds may linger across SE Mass as well as Cape Cod and the islands. It will be a cold night, however, with temperatures bottoming out in the single digits to the mid teens inland, ranging to the upper teens to mid 20s along the shoreline. These readings will run up to 5 degrees below seasonal normals inland.
LONG TERM /THURSDAY THROUGH TUESDAY/. Highlights .
* Mainly dry Thu into Fri with near to slightly below normal temperatures rebounding above normal by Fri
* Still monitoring for a potential storm Saturday/Sat night, but forecast confidence remains very low on details
* Mainly dry with above normal temperatures early next week
Details .
Large high pressure late this week should lead to dry weather. Near to below normal temperatures expected Thursday, until this high pressure passes by our region into Friday. Then temperatures are once again expected to be above normal.
Still monitoring the potential for a coastal storm sometime this weekend. The energy expected to be a part of this system should move over western North America tonight into tomorrow. Expecting most of the details to emerge from the noise over the next couple of days. There remains a large degree of spread in the ensemble solutions, so it is important to not lock in on a singular operational model run at this time.
The general idea from the 28/12Z guidance is for a low pressure to move northeast along the eastern Seaboard Saturday into Sunday. Still some question as to how close this low pressure tracks to southern New England, as well as when does it strengthen. The consensus solution is for a farther offshore track, with the strengthening occurring after this low passes us by. Only the operational GFS significantly deepened the low pressure closer to our region.
At this point, will continue to mention a broad period with a chance of rain and/or snow. Expecting changes with the details in later forecasts. This remains a low confidence portion of the forecast.
A drying trend should follow Sunday into early next week behind this departing cyclone. Thinking above normal temperatures for this portion of the forecast.
AVIATION /21Z 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. MVFR CIGS develop across the eastern slopes of the Berkshires and across central and eastern Cape Cod as well as Nantucket. Best chance for MVFR CIGS and local MVFR VSBYS is across Cape Cod and Nantucket where scattered ocean effect rain and/or snow showers may fall.
Wednesday .
Any isolated snow showers across outer Cape Cod early will end with local MVFR CIGS/VSBYS through 13Z-14Z. Otherwise, expect VFR conditions. N-NW winds 10-15 kt, highest along E coastal terminals.
Wednesday night .
VFR conditions. Light N winds. Good visibility.
KBOS Terminal . High confidence in TAF through 00Z, then moderate confidence as MVFR ceilings move in across the mid and outer sections of Cape Cod into Nantucket and develop across N central/W Mass tonight.
KBDL Terminal . High confidence in TAF.
Outlook /Thursday through Sunday/ .
Thursday through Friday: VFR.
Friday Night: VFR. Slight chance SN.
Saturday: Mainly VFR, with local MVFR possible. Breezy. Chance RA, with a slight chance SN.
Saturday Night: Mainly VFR, with local MVFR possible. Breezy. Chance SN or RA.
Sunday: VFR. Breezy. Chance SN, with a slight chance RA.
MARINE. Short Term /through Wednesday Night/ . 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 E of Cape Ann to Cape Cod and Nantucket, dry elsewhere. Seas 4 ft or less. Visibility may lower to 3 miles in any showers. Good visibility elsewhere.
