Area Forecast Discussion National Weather Service Boston/Norton MA 517 AM EST Mon Dec 11 2023
SYNOPSIS
Multifaceted storm with heavy rain and potentially damaging wind gusts will impact southern New England this morning. Behind this departing system, the week ahead looks dry. Expecting a cool-down mid week, before warming up once again towards next weekend.
NEAR TERM /UNTIL 6 PM THIS EVENING/
After further analysis this morning, made significant changes to wind headlines across both land and water. Began the process of downgrading wind headlines, both in terms of magnitude and duration. With the front almost completely offshore early this morning, the core of the strong low level jet has also been shunted east. Thinking most of the Wind Advisories can be dropped at 7 AM. Kept the High Wind Warning for the Cape and islands into early afternoon.
Also tweaked temperatures and winds based on latest observed trends.
249 AM Update...
Latest guidance suite and observations indicated a quicker timing for the eastward progression of a cold front across southern New England. Latest observations already had this front past Nashua NH, Worcester MA and Willimantic CT. Based on current timing, that would place this front along the east coast of MA towards 7 AM, then finally offshore towards mid morning.
This is about 5 hours faster than the previous forecast.
This is important to several aspects of the forecast, mainly due to the wind shift and reducing the duration of heavy rainfall. This may also limit the magnitude of wind speeds, which were just starting to gust up around 45 mph in spots as of this writing. While still expecting at least some snowfall across the east slopes of the Berkshires, the quicker timing should limit amounts. Thinking snowfall amounts will remain below 3 inches. Hence no need for a Winter Weather Advisory there.
The latest NationalBlend appeared to have a rather good handle on this timing. Thus used it for the basis for the forecast this morning. Expecting nearly steady to falling temperatures through the day, meaning early high temperatures. Will address the hydrology and coastal flooding concerns in their own section below.
Wind continue wind headlines as they currently are. Will reevaluate and possibly make changes with the 4 AM forecast.
SHORT TERM /6 PM THIS EVENING THROUGH 6 PM TUESDAY/
High pressure then builds east towards the Mid Atlantic coast tonight into Tuesday. Expecting dry weather and mainly clear skies with a diminishing west wind. Near normal temperatures during this portion of the forecast.
LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/
Key Points: - Mainly dry weather expected - Near to below normal temperatures give way to another warmup by next weekend
Upper level pattern should feature a broad trough over much of eastern US through midweek, but with a lack of downstream blocking, the synoptic pattern remains progressive and this trough will exit to Maritimes. This will allow for a pattern change late this week as an upper ridge takes hold and brings yet another warmup into next weekend. This pattern also favors dry weather overall with a large high pressure nearby to our south and west.
AVIATION /10Z MONDAY THROUGH FRIDAY/
Forecast Confidence Levels:
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
High confidence in trends. Moderate confidence in timing.
Significant changes to the timing of a cold front, which has already crossed most of southern New England early this morning.
expecting this front to be offshore by 15Z, even across the Cape and islands. However, there are some complications which may alter this timing. A low pressure may develop more quickly, which would then slow the passage of this front.
MVFR to IFR east of this front, with rapid improvement to VFR to the west, thinking by 15-18Z. Areas of MVFR ceilings lingering near the higher elevations.
Strong low level jet of 80 kt passing across SE MA this morning will result in significant LLWS. Winds gradually diminish through today, but remain gusty through sunset. Gusty SW winds for Tuesday, but not as strong as today.
KBOS Terminal...High confidence in trends. Moderate confidence in timing.
KBDL Terminal...High confidence.
Outlook /Tuesday Night through Friday/...
Tuesday Night through Wednesday: VFR. Breezy.
Wednesday Night: VFR. Windy with areas of gusts up to 30 kt.
Thursday: VFR. Windy with local gusts up to 30 kt.
Thursday Night through Friday: VFR. Breezy.
MARINE
Forecaster Confidence Levels:
Low - less than 30 percent.
Medium - 30 to 60 percent.
High - greater than 60 percent.
based on the latest observed trends, confined the Storm Warning to the outer coastal waters, as well as Nantucket Sound. Gale Warnings elsewhere, but only through 7 AM for Boston Harbor and Mass Bay, as well as Narragansett Bay and Block Island Sound.
Remaining Gale Warnings continue into mid morning. Further headline changes expected with later forecasts today as winds continue to diminish slowly.
249 AM Update...
A cold front was quickly approaching the waters this morning.
Winds were just starting to ramp up across the waters. Starting to think we may not quite get to storm-force winds, but the threat remains. Winds were southerly at 88 kt at 2,000-2,500 ft above ground, and it would not take much more mixing to bring some of this down to the surface. Will maintain the Storm Warnings for now, and continue to monitor. May be able to downgrade to Gale Warnings later this morning.
Moderate to heavy rainfall will reduce visibility at times this morning. An abrupt and significant shift in winds is expected as this cold front crosses the waters. Seas gradually diminish through the day, but seas will still be rough on the waters into Tuesday.
Outlook /Tuesday Night through Friday/...
Tuesday Night: Low risk for Small Craft Advisory winds with gusts up to 25 kt. Areas of rough seas.
Wednesday: Low risk for Small Craft Advisory winds with gusts up to 30 kt. Seas up to 5 ft.
Wednesday Night: Strong winds with gusts up to 35 kt. Seas up to 5 ft.
Thursday: Moderate risk for Small Craft Advisory winds with local gusts up to 30 kt. Local rough seas.
Thursday Night: Low risk for Small Craft Advisory winds with gusts up to 25 kt. Seas locally approaching 5 ft.
Friday: Moderate risk for Small Craft Advisory winds with gusts up to 25 kt. Areas of seas approaching 5 ft.
HYDROLOGY
Already seeing rises on some of the faster responding streams, creeks and smaller rivers. The faster progression of a cold front will limit rainfall. Thinking additional rainfall of 0.50-1.50 inches going forward. Areal flood warnings already posted, and we will be monitoring the rivers closely through this morning. Travelers should remain alert for flooded areas this morning. Turn around, don't drown.
The Flood Watch continues for now, but may be cancelled earlier than its current end time with later forecasts.
TIDES/COASTAL FLOODING
Coastal Flood Advisory canceled.
The faster progression of a cold front forced wind directions to shift to the W to NW prior to the time of high tide by about 2-3 hours. This timing offset was enough to prevent further coastal flooding along the south coast of MA and Narragansett Bay.
