After the generally dreary weather of March and April, anyone looking forward to summer will surely enjoy an early taste this week, as temperatures flirt with 80°F (27°C) in the coming days.

The upper-level flow over the United States for the next few days will be dominated by a southwesterly jet. The flow is navigating around a trough over the Four Corners before turning toward us. This will spread warmer air across the eastern United States for the next few days, and the Boston area will be no exception.

With few clouds today and tomorrow, the days will be warm, but the temperatures will drop sharply in the evening as Earth radiates to space, so while the daytime temperatures suggest dressing in T-shirts and shorts, slightly heavier clothing might be needed in the evening.
