It was already about to be a deeply unusual Christmas in Boston, and now this.

Forecasters are sounding the alarm about extraordinarily high winds and a whole lot of rain as a storm heads to the Boston area just in time for the holiday, with gusts that may reach an eye-popping, evergreen-toppling 60-65 miles per hour. Winds are expected to arrive Thursday afternoon, and slowly pick up late at night and into Friday morning, forecasters say.

“The peak of the event is going to be overnight and into early tomorrow morning. Around when people are waking up, we’re still going to be seeing some pretty strong wind gusts and heavy rain before things start to calm down a little bit in the afternoon,” says Rob Megnia, meteorologist with the National Weather Service Boston. “In the morning hours, things are going to be pretty hectic.”

The reason for this, Megnia says, is the jet stream is expected to pass through the Northeast at a particularly low level and pretty far in from the coast. The result, he says, will be some of the strongest winds the area has experienced “in recent memory.”

“We’ve never seen a low level jet or the forecast for wind this strong during this time of year over the Northeast,” he says. “This is going to be a pretty, pretty strong event.”

[HIGH WIND WARNING] A High Wind Warning has been issued from midnight Thursday night through 12 PM Friday across RI, E. MA and N. CT. Numerous power outages are expected as winds may gust to 70 mph Christmas morning. #MAwx #RIwx #CTwx

The NWS has issued a high-wind warning throughout southern New England, and from the looks of it Boston is slated to see some of the worst of the storm, as the predictions about max wind gusts are up in the mid-60s up in coastal areas, including the city, while they’re a little lower—around 40-50 miles per hour—further west. The warning is in effect in the Boston area from midnight to 4 p.m. Friday.

While wind is the big star of this storm, NWS meteorologists are also warning that heavy rains of 2-3 inches combined with the melting snow from the recent snowstorm could bring severe flooding to some areas, among them urban streets with poor drainage. NWS has issued a flood watch, as well as a reminder to drivers not to drive through flooded areas. Its mantra: “Turn Around, Don’t Drown.”

Unseasonable warmth is also expected. If the forecast holds true and temperatures climb into the 60s, it could be among the warmest Christmases Boston has ever recorded. The warmest Christmas Day on record was 65 degrees in 1889. The warmest Christmas Eve came in 2015, when it was a steamy 69 degrees.

We are likely to break some precip records on X-mas, as 1-3″ is expected across SE NE. A few other records that are in jeopardy include the record max low and the record high. If we hit 60 at any of our climate sites, we will have one of the top 5 warmest X-mas days on record.

So, best wishes to Santa this evening. Gov. Charlie Baker has already assured us all that St. Nick has cleared the state’s COVID protocols. Here’s hoping his sleigh’s aerodynamics are up to snuff.
