As our post-holiday winter storm continues to pummel parts of the Plains and Midwest while severe weather threatens the South, the Northeast is up next to feel the impacts from this storm. Thankfully, blizzard conditions nor severe storms are expected, but there will still be the risk for heavy rain, localized flash flooding, and some wintry precipitation on Friday.

Impacts may begin as early as this evening as moisture begins to sneak into the region. A few showers will become possible late in the day this Thursday in the Mid-Atlantic, potentially forming ahead of the main line of rain back to the west.

Then beginning in the wee hours of Friday morning, that steady rain will work into interior portions of the Northeast, with a line of moderate to heavy rain spanning from New York down through the Appalachian Mountains. Most of the I-95 corridor should remain dry until the morning commute on Friday.

Now across parts of Upstate New York and northern New England, snow and/or wintry precipitation will be seen beginning Friday morning. Sleet, freezing rain, and some snow is expected across the northern portion of New York, while much of northern New England and even northern Massachusetts experiences a light to moderate snow. There is even the risk for a brief period of snow in the Boston metro around sunrise, but little to no accumulation will be the most likely scenario.

Then during the day Friday, that line of rain will trek to the East Coast, affecting the Northeast megalopolis during the morning and midday hours for the most part. Some of this rain may lead to ponding on the roadways and even some flooding. Many cities are experiencing a top 5 wettest year, so it won’t take much rain for flooding to occur. That risk will be greatest near the coast and in the Appalachian Mountains. It’s not until late in the day when the cold front will push through, ushering in dryer but slightly cooler air beginning in the evening hours. Eastern New England and down toward the southern Mid-Atlantic coast may have to wait until overnight Friday for the precipitation to completely clear out.

In terms of the wintry precipitation, the snow and wintry mix will transition into a rain across Upstate New York, Vermont, and New Hampshire by midday. Meanwhile in Maine, a rather heavy snow may be in the cards Friday morning and into the midday time period. By the end of the day, however, rain should takeover, but not before several inches of snowfall comes down.

Another component to this rain and snow mess will be the winds. Widespread wind gusts of 25-40 mph are expected, with localized gusts up to 55 mph near the coast. This may lead to spotty power outages.

That cold front will give way to sunshine for Saturday, and temperatures will actually be above average across most locales. There will be some lake-effect snow and passing snow showers across portions of the Great Lakes region, but for most, the day will feature no significant severe weather.
