If you want to see what a developing strong negative NAO pattern looks like, take a look at this morning’s water vapor satellite image. The upper low associated with the coastal storm off the New England coast is clearly dominating the weather pattern for the much of the Northeast and Mid Atlantic. The upper [...]

This morning an energetic disturbance over the Ohio Valley is racing east, slightly faster than most model guidance have projected, and is producing light snow showers over parts of western Pennsylvania. This disturbance will continue to move east, but will run into the surface high pressure currently sitting over the Philadelphia and New York [...]

High pressure this morning over the Great Lakes is slowly building into the forecast area and providing the region with clear skies, light winds, and comfortable temperatures.
