Weather - Free Fall
Free FallBy Gerard Roe
The weather over the next few days will be dominated by a plunge southward of a large pool of cold air. This excursion is associated with a large scale amplification of the jet stream pattern. This has resulted in a strong cold front swinging through the midwest on its way here. Temperatures across the front differ by as much as 25°F (14°C). The northern midwest will see its first snows of the year, and Thursday night will bring the chance of frost in some parts of Massachusetts.
Wednesday will see a gradual clouding up due to overrunning warm air in advance of the front. There is a likelihood of rain late Wednesday and early Thursday morning ahead of the front, which will pass by sometime in the late morning. Temperatures will then drop rapidly accompanied by a shift in the winds to northerly.
Today: Fair. Partly sunny early then increasing high clouds. Winds moderate from the South and becoming stronger as the day progresses. High 70°F (21°C).
Tonight: Cloudy, with light rain likely after midnight. Low 56°F (13°C).
Thursday: Any drizzle clearing during the morning. Much cooler, clearer after frontal passage. Late morning high of 60°F (16°C). Low 36°F (2°C).
Friday: Clear and cool. High in the mid 50s (13°C). Low 35 (1°C).
