Once it dries out, the wind will kick it up a notch

A pedestrian in Boston walked through steam from a manhole cover.

It’s hard to believe how quickly this winter has gone, at least in my own mind. We are now approaching the final days of February and also the close of meteorological winter. We have another storm on the way, but like so many this winter, it will be too warm for any major amounts of snow.

NOAA Data
So far no day has produced 6 inches or more of snow this season in Boston.

A storm system will move through the Great Lakes on Saturday night into Sunday, and then become very intense in Eastern Canada. This storm will bring precipitation around midnight, mostly in the form of rain. There may be some frozen precipitation at the onset west of Interstate 495, and if you’re traveling very late tonight or early tomorrow morning, watch for a few slippery spots.

A fast-moving area of rain that may begin as snow west of Interstate 495 will arrive in before dawn Sunday. (COD Weather)

The rain tomorrow will not be too intense but certainly the morning hours will be wet. During the afternoon, the rain will taper off to showers and skies should remain mostly cloudy. Most places will receive half an inch to one inch of rain, although there won’t be enough to create any flood issues. The rain will be ending west to east from 2 to 4 p.m. Sunday.

The winds will pick up Sunday night. Although the storm will be hundreds of miles away, the pressure gradient between the storm and the air over us will be quite pronounced. Nature doesn’t like that imbalance and the wind will be its way of trying to re-calibrate things. The bigger the pressure gradient the bigger the winds, and we are certainly going to see some fairly strong winds Sunday night and Monday. The strongest winds will be late morning into the middle part of the afternoon, and there can be some pockets of damage and subsequent power outages.

Winds will gust at 50 miles per hour or more Monday, especially during the middle of the day. (COD Weather)

Power outages are difficult to predict. However, I would have everything fully charged just in case. I don’t expect this to be a widespread issue. The winds may also be strong enough to create a few delays at Logan Airport. Smaller regional airports will also likely see delays.

The winds will subside Tuesday, but they will still be noticeable all day. Tuesday will be very cold with highs only in the 20s and windchill readings near zero in the morning. This cold, dry weather will continue the rest of the work week. Another storm will arrive next weekend. It presently appears to be mostly a rainmaker, but it also looks to be an intense storm, so we’ll need to keep an eye on this one.
