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/
1 PM Update...
Precipitation has come to an end across southern New England as ceilings lift and begin to break up from southwest to northeast.
Gusty, drying, northwest flow continues to build to ~25kt over the next few hours.
9 AM Update...
System appears to be moving slightly faster than forecast with the front now exiting the Cape; in turn, taking the damaging wind threat with it. Given the wind threat has diminished, the High Wind Warning has been terminated at the top of the hour.
Additionally, storm warnings across the waters are being converted to small crafts and will continue to be converted through the morning as the front moves east of the outer waters.
Minor river flooding is occurring or will begin occurring today across many areas. We will continue to monitor the threat over the next 12-24 hours to add warnings where necessary.
Rapid clearing will occur behind the departing system between 15-18Z, with breaks of sunshine expected with the exception being the high terrain which may retain cloud cover into the evening.
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 /17Z MONDAY THROUGH FRIDAY/
Forecast Confidence Levels:
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
18Z Update...
High confidence in trends, moderate confidence in timing of VFR development.
Through tonight...
Conditions will continue to improve across all terminals this afternoon and early evening with a transition from MVFR to VFR over the next two to three hours. Anticipating all terminals will be VFR by 22Z. Gusty NW flow maintains 20-25kt through sunset before diminishing slightly to 15kt overnight. Gusts will be slowest to diminish over the high terrain.
Tomorrow and tomorrow night... High Confidence
VFR through the period as winds become more SW around daybreak Tuesday. Winds generally 10kt with gusts to 15kt. Tranquil conditions and SW flow continue overnight.
KBOS Terminal...High confidence in trends. Moderate confidence in timing.
KBDL Terminal...High confidence.
Outlook /Tuesday Night through Friday/...
Tuesday 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: Winds less than 25 kt. Areas of rough seas.
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.
