Tuesday 9 a.m.
Yesterday, the Buffalo area had snow flurries. Tomorrow, the temperature will top 70. Yesterday started with frost in some Chicago suburbs; today, it's going to middle 80s. And, at Goodland Kan., where they had almost 4 inches of snow on May 1, it was 92 yesterday! The heat in the middle of the nation will lose some of its steam on the way east, but at Saranac Lake, N.Y., this morning's low of 24 will replaced by 64 tomorrow afternoon.
An energetic low pressure area west of Winnipeg this morning will vault past Vermont by Thursday morning. Winds have gusted past 40 mph in the Dakotas this morning. One concern is that with the warm air blasting northeast while the upper air temperature rise moderately, the stage is set for gusty thunderstorm development. These could affect parts of the Great Lakes tonight and the area from New York to Virginia tomorrow.
On this map, you can see the large area of southwesterly flow that's advancing eastward. This flow is bringing in much warmer air.
For the Ides of March, Shakespeare's play titles put the weekend forecast onstage. Hint: It's not just A Winter's Tale.
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???
