Friday 10 a.m.
The cold weather pattern will continue in the Northeast through next week. There are signs of a pattern shift next month, but we would expect that eventually anyway. The biggest concern centers on what a snowstorm from the Central states does in the East. The video explores what various computer models were predicting. I think there is a reasonable chance this will be the biggest snowfall of the snow season from D.C. to Philadelphia. However, since Washington has recorded less than 2 inches so far and Philadelphia around 7, the bar is set low for this storm. Please check AccuWeather.com's latest information all weekend as we narrow down the possibilities.
As of early Friday, this was the snow accumulation forecast for the weekend. This will be updated all weekend.
As you can see, issues in the Middle Atlantic states were not resolved for this map.
This series of maps shows how the extreme cold today in the Northeast is replaced by somewhat milder air tomorrow and Saturday.
This pressure map shows the storm center. The front to the east (red line) marks the boundary between warm air to the south and progressively colder air to the north.
This draft forecast map shows the heaviest snow from the upcoming storm is likely from northern Illinois to northern New England. Tomorrow afternoon, conditions may range from blizzard conditions in central New York to spring style thunderstorms in southern Pennsylvania.
This is the chameleon month of March. Always searching for a sense of identity, its days stagger through punches of waning winter, dance with the sunlit caresses of coming spring and hide behind thick clouds through the wind-swept battles between the two.
In the early to middle part of next week, there could be a hint of spring in the region from Illinois to New Jersey. This is a forecast map for next Tuesday morning. The average rain-snow line is midway between the last blue dashed line and the first red dashed line, and.... is that a daring daffodil???
There is uncertainty about how far north a storm from the Gulf states will come on Friday. This morning's NAM is rather bullish on the system. However, it suggests milder weather for the Northeast for a while this weekend before the next cold front arrives.
