Tuesday Night Technical Discussion

The cutoff low moving through the Great Lakes will continue to move north on Thursday into northern New England with only a few rain or snow showers possibly lingering in western Pennsylvania early on Thursday. Winds will shift WNW to NW Wednesday afternoon and become breezy with some ridge tops in western Pennsylvania possibly reaching 30kts. High pressure will move in from the south later in the day on Thursday bringing drier conditions through Friday. A weak cold front will try to push through late in the day on Friday only bringing a slight chance for a snow shower or two in northern Pennsylvania Friday night. The front will quickly exit Friday night with high pressure taking over for the first half of the weekend. Another cold front will approach the state from the west on Sunday bring cloudy skies later in the day and the chance for a few rain showers overnight across extreme western Pennsylvania. The showers will move across the commonwealth on Monday and possibly change over to a few snow showers by Tuesday across western Pennsylvania as the 540 line pushes west to east.
