- A low-pressure system will develop off the Northeast coast late this week.
- Locally heavy rain and higher-elevation snow are expected, along with gusty winds.
- Chilly conditions are expected to accompany this system.
A potent coastal low will bring rain, snow and gusty winds to parts of the Northeast late this week.
A low-pressure system will slide into the Northeast on Thursday and a second area of low pressure is expected to form off the mid-Atlantic coast.
This area of low pressure off the coast will strengthen as it moves slowly northeastward toward New England Thursday night into Friday.
Ample moisture will accompany the coastal low, which means some beneficial precipitation is ahead for parts of the Northeast. In addition, a cold pocket of air will emerge over the Northeast Thursday night into Friday, which will allow some of the precipitation to fall as snow, particularly in the higher elevations.
Forecast
Rain will start to spread into parts of the Northeast late Wednesday. However, the heavier precipitation will likely begin Thursday night as the coastal low organizes and intensifies.
Thursday - Thursday Night
Locally heavy rain is likely Thursday into Thursday night near the Northeast coast.
Farther inland, some of the higher elevations could see rain change to snow or a mix of rain and snow Thursday night as temperatures tumble into the 30s.

Rain will continue along the New England coast southward into northern New Jersey. A mix of rain and snow is expected farther inland, particularly in the higher elevations.
Gusty winds are also anticipated at times, especially closer to the coast.
Friday's Forecast
(The green shadings depict where rain is expected. Areas that are shaded blue are expected to see snow. Purple-shaded locations may see either rain or snow. Areas in pink are expected to see sleet or freezing rain (ice).)Friday Night
Most of New England and parts of eastern New York will see persistent rain and snow through Friday night. Winds will remain gusty, mainly along the coast.
The coastal low will pull away from the region by Saturday, although some scattered rain and snow showers might linger into Saturday afternoon.
Friday Night's Forecast
(The green shadings depict where rain is expected. Areas that are shaded blue are expected to see snow. Purple-shaded locations may see either rain or snow. Areas in pink are expected to see sleet or freezing rain (ice).)How Much Snow and Rain?
Snowfall totals will depend on the exact track of the low. However, some higher elevations of New England and eastern New York have the potential to see heavy, wet snow accumulate.
More than 6 inches of snow is possible in portions of the Berkshires, Green Mountains, White Mountains, Catskills and Adirondack Mountains.
Locally heavy rainfall is likely in southern and eastern New England, with lower rainfall amounts farther north and west.
This moisture will be beneficial in some spots as about 40% of the Northeast is abnormally dry, according to the most recent U.S. Drought Monitor.
Snow and Rain Outlook
Chilly Temperatures
Below-average temperatures for mid-April will accompany this late-week system in the Northeast. Highs will be as much as 10 degrees colder than average on Friday.
Friday's highs will only top out in the 50s for many spots, which will be a noticeable change from widespread temperatures in the mid- to upper 60s earlier in the week.
Low temperatures will also return to near average late this week, with most locations dipping into the 30s and 40s Friday through Sunday mornings.
