A weak area of high pressure over the Northeast may bring us a few peeks of sunshine today, however, by tomorrow a potent storm system from the deep south will be taking its place. This low pressure system will bring windy conditions, scattered showers, and a chance for a gusty thunderstorm. Finally, that system will move out of the area on Friday and slightly cooler conditions will follow for the weekend. Typical Forecast • Today: Mostly cloudy skies with a few peeks of sun. High: Near 65 • Tonight: Mild and breezy with increasing clouds and a chance of showers. Low: 54-58 • Thursday: Windy with showers and a possible thunderstorm developing. High: 64-68 • Thursday Night: Evening showers, breezy and mild. Low: 44-48 • Friday: Mix of clouds and sun with a mild breeze. High: 54-58 www.atmos.millersville.edu
