.WHAT HAS CHANGED...
No significant changes since the previous forecast update. A Winter
Weather Advisory remains in effect for the threat of freezing rain
across portions of southern New England tonight through tomorrow
morning. Most locations along the I-95 corridor will experience a
light glace of ice, though locations across interior southern New
England may see ice accumulation between 0.1" and 0.2". Plan on
slick travel Tuesday evening through Wednesday morning.
&&
.KEY MESSAGES...
- Freezing rain will create hazardous road conditions tonight
through tomorrow morning for much of southern New England.
- Pattern change brings milder temps with rain later in the
week; no flooding expected.
&&
.DISCUSSION...
KEY MESSAGE 1...Freezing rain will create hazardous road conditions
tonight through tomorrow morning for much of southern New England.
A progressive frontal system will move through the Northeast tonight
into Wednesday morning, bringing a period of mixed precipitation to
much of southern New England. An upper-level low currently over the
Midwest and Great Lakes will traverse eastward this evening and
overnight, while an associated warm front lifts north across the
region. As low-level warm advection increases overnight,
temperatures aloft will rise above freezing, resulting in melting of
any frozen precipitation as it falls through the warm layer.
However, surface temperatures especially across interior locations
will remain at or below freezing, allowing precipitation to refreeze
on contact and fall primarily as freezing rain.
Precipitation will overspread the region from west to east between
approximately 7PM and 9PM. Areas north and west of the I-95
corridor are expected to see freezing rain as the dominant
precipitation type, with ice accumulations generally ranging
from a few hundredths of an inch in lower elevations to up to
two-tenths of an inch across higher terrain of interior
Massachusetts. These amounts will be sufficient to create slick
and hazardous road conditions.
Across eastern and northeastern Massachusetts, including areas along
and east of I-95, a few hours of freezing rain are expected this
evening before surface temperatures rise above freezing, allowing a
changeover to plain rain roughly after midnight. As a result, ice
accretion in these areas should be limited in duration and magnitude.
Most of Massachusetts remains under a Winter Weather Advisory for
freezing rain, with the exception of Plymouth County, southern
Bristol County, and the Cape and Islands. Advisories are also in
effect for Providence and Kent Counties in Rhode Island, as well as
Hartford, Windham, and Tolland Counties in Connecticut.
Precipitation is expected to taper off near the end of the Wednesday
morning commute, though there is some uncertainty regarding the
potential for freezing rain to redevelop across portions of
eastern Massachusetts Wednesday morning. This would be dependent
on how quickly colder air is drawn southward on northerly to
northwesterly flow associated with a secondary surface low.
Confidence in this scenario is lower, but it will need to be
monitored closely should surface temperatures fall back below
freezing.
Dry and seasonable conditions return Wednesday afternoon and persist
through Wednesday night.
KEY MESSAGE 2...Pattern change brings milder temps with rain late
Friday clear through the weekend.
High confidence that following Wednesday's mixed precipitation event
we'll see a pattern shift toward a milder airmass with prolonged
unsettled weather for Friday into the weekend. A building
subtropical ridge Thursday into Friday keeps things dry while
increasing warm SW flow pushes temps back into the 40s Thursday and
near 50F Friday. We won't see a significant cool down (to normal)
until Monday once the weekend system fully pushes through. That
system consists of a broad trough and a series of low pressures, the
first of which tracks north of SNE and brings a round of warm
frontal rainfall late Friday into Saturday. The more robust system
follows shortly after with a deeper trough digging in and a
secondary low forming over the region during the weekend. This will
combine good dynamics with ample moisture (PWATs nearing 1.5"). Too
soon to nail down specifics but guidance suggests this could squeeze
out 0.50-1.00" of rain before drier air returns for Monday. Overall,
a very wet weekend looks in store.

.AVIATION /00Z WEDNESDAY THROUGH SUNDAY/...
Forecaster Confidence Levels...
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High -greater than 60 percent.
00z TAF update...
Tonight... Moderate Confidence.
Lowering cigs/vsbys becoming widespread IFR-LIFR as RA and FZRA
overspreads the region. Mostly FZRA interior with brief snow
possible at onset north of Route 2. Brief FZRA may impact BOS-
PVD corridor at the onset of precipitation 02-05z. Otherwise,
rain near the coast. Light N-NE wind becoming E near the coast.
Wednesday... Moderate Confidence.
IFR-LIFR conditions persist in the morning with gradual
improvement to MVFR-VFR through the afternoon away from the
coast. Areas of FZRA or FZDZ in the interior may expand toward
the E-NE MA coast during the morning. Winds shifting to N-NW
during the morning increasing mid-late afternoon
Wednesday night... High confidence.
Mainly VFR, although MVFR may linger into the evening for
Cape/Islands. NW wind 5-15 kt.
KBOS Terminal... Moderate Confidence.
IFR cigs with LIFR cigs/vsbys developing late tonight into Wed
morning. Rain develops after 02z but could begin as a brief
period of FZRA before temps climb above freezing. Winds shift
back to N-NW Wed morning and that may lead to some -FZRA/-FZDZ
as colder air is drawn southward.
KBDL Terminal... Moderate Confidence.
Conditions lowering to IFR tonight with pockets of LIFR. Areas
of FZRA develop after 00z transitioning to -RA/-DZ late tonight
as temps climb above freezing.
Outlook /Thursday through Sunday/...
Thursday: VFR.
Thursday Night: VFR. Slight chance FZRA.
Friday through Friday Night: Mainly VFR, with local IFR
possible. Breezy. Chance RA.
Saturday: Mainly VFR, with areas MVFR possible. RA likely.
Saturday Night: Mainly MVFR, with local IFR possible. Breezy.
RA.
Sunday: Mainly VFR, with local MVFR possible. Windy with local
gusts up to 30 kt. Chance RA.
&&
.MARINE...
Forecaster Confidence Levels...
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
Tonight through Wednesday night... High Confidence.
A warm front overspreads the region early this evening with
periods of rain overnight. Seas are 1' to 3' today, increasing
2' to 4' overnight. Light E/NE wind today, then E/SE tonight.
Wednesday, low-pressure system exits the Gulf of Maine, increasing
wind from the W, gusting between 20 to 30 knots. Occasional rain
showers tapper off from southwest to northeast during the late
morning into the early afternoon. Increasing seas across the
southern waters, between 4' and 8', eastern waters 2' to 5'. These
conditions will lead to a Small Craft Advisory for the outer
marine zones and south coastal waters. Steady 15-20 knot
sustained northwest winds persist Wednesday night into Thursday
morning.
Outlook /Thursday through Sunday/...
Thursday: Winds less than 25 kt. Areas of seas approaching
5 ft.
Thursday Night: Winds less than 25 kt.
Friday through Friday Night: Low risk for Small Craft Advisory
winds with gusts up to 25 kt. Local rough seas. Chance of rain.
Saturday: Winds less than 25 kt. Areas of seas approaching
5 ft. Rain likely.
Saturday Night: Low risk for Small Craft Advisory winds with
gusts up to 25 kt. Areas of rough seas. Rain.
Sunday: Strong winds with gusts up to 35 kt. Rough seas up to
11 ft. Chance of rain.
