A pre-Valentine’s Day snow storm is brewing as the weather pattern reverses in the northeastern United States

It may be time to dust off your snow shovels, as a volatile weather pattern could send a snowstorm over parts of the Midwest and Northeast just days after a spell of unseasonable warmth.

AccuWeather meteorologists are closely monitoring a storm that will likely bring a band of accumulating snow from parts of the Midwest to the Northeast early next week.

The location and amount of snowfall will depend on the strength of the storm, which may fluctuate, and the path of the storm, which may shift north and south over the next few days.

In the short term, temperatures will rise in the wake of the Atlantic storm that buried Nova Scotia under feet of snow earlier this week. The flow of dry air west of that storm provided days of bright sunshine and cool nights across much of the central and eastern United States.

As that Atlantic storm moves away, a southwesterly air flow will extend from the central states to the east through Friday.

On the weekend, highs will range from the 40s F over the northern tier of New England to the 50s spread around the Great Lakes, central Appalachia and upper mid-Atlantic to the 60s over most of the Ohio Valley and southern states.

However, the clock will be ticking on a warmer weather pattern once it starts.

“Although the January thaw and breakaway from the stormy pattern extended into early February, there will be a change in pattern with a potentially impactful storm swinging across the Midwest and Northeast states Monday into Tuesday,” AccuWeather Meteorologist Dean DeFore said. .

First, the Southcentral and Southeastern states will see the return of cloudy and rainy conditions centered this weekend.

The potential storm referred to by DeVore includes a band of accumulating snow that could first appear over parts of the southern High Plains on Sunday and extend across parts of the central Mississippi Valley into the Ohio Valley from Sunday night into Monday. However, the amount of snowfall in this area can be limited because the air may not be cold enough, resulting in more raindrops than snowflakes.

The best chance for several inches of snow and slippery travel will be near the Ozark Mountains in southern Missouri.

“Cold air will gradually be drawn into this storm as it moves from the central states to the East Coast,” AccuWeather Senior Meteorologist Bernie Reino said. “How quickly this happens will depend on how quickly the storm strengthens.”

If the storm remains weak, it will likely move east with only small accumulations of snow from the Ohio Valley into the central and southern Appalachians and possibly a wintry mix in the mid-Atlantic late Monday into Tuesday.

If the storm strengthens and strengthens, it will move northward, producing a wide swath of accumulating snow from central Appalachia to New England, with heavy rain and thunderstorms in the south.

Both scenarios and others involving significant northerly and only intermittent precipitation are still in play. Most will still allow some snow to fall from the Ohio Valley to parts of the Appalachians.

AccuWeather has released a forecast map of snow accumulation for the Northeast that represents the input of dozens of meteorologists with hundreds of years of combined experience.

If the storm develops to its full potential, heavy snow may occur in parts of the Northeast and some people may spend the first part of Valentine’s Day prospecting or dealing with potential travel delays in the storm’s aftermath.

“One thing is certain, this storm will start a pattern that brings cooler, more active weather from the Midwest to the Northeast with enhanced shots of seasonally cold air masses with the potential for some clipper systems to lead to snow events,” DeFore said.
