The snow that was sequestered from downtown D.C. yesterday was appropriated for Boston this morning, where the snow and a temperature drop to the freezing point turned the morning commute into a nightmare. Since a liberal amount of snow (3-6 inches in many spots from Providence on past Boston (some computer models print out much more, but we'll watch it for now)) will fall tonight, it will be very slippery with poor visibility. Conservative driving habits may keep you independent from injury or accidents.
The cold air will depart this weekend, and a welcome sojourn toward springtime weather will spread from Chicago to Boston between Friday and Sunday.
Here is our working draft of projected snow amounts. This draft map is updated regularly is not to be copied elsewhere.
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.
Many people have requested some real spring weather in the Northeast. Looking out two weeks with the European model, it still looks chilly on this flow aloft forecast for March 19.
This map shows accumulations as of 8 a.m. They have continued to increase since then in Delaware, Maryland and Virginia.
