Weather Underground Forecast for Thursday, March 29, 2012.
More wet weather activity will continue across portions of the West and Northeast on Thursday, while thunderstorm activity takes shape over the Central U.S.
In the West, a strong frontal system will sweep across the Pacific Northwest late Wednesday through Thursday morning, bringing showers, heavy snow to the mountains and brief coastal high wind to areas of the Pacific Northwest and northern California. Precipitation will spread across the Northern Intermountain West through the day as the frontal disturbance moves inland. By Thursday night, another system will reach the region with similar precipitation and breezy to windy conditions. This activity will continue into Friday.
In the Central U.S., energy ejecting out of the West will kick up rain and thunderstorms in the Northern Plains. To the south, moisture pooling along a stalled frontal boundary extending through the Central Plains and the Mid-Mississippi Valley will translate into showers and thunderstorms. Storms across parts of the eastern Central Plains and the Mid- and Lower Missouri Valley may turn severe with damaging wind gusts. Further south, additional showers and thunderstorms are expected to spread across the central Texas.
In the East, the low pressure system affecting parts of the Northeast will quickly move east of the region. As this system departs, Maine will see mostly cloudy skies with some lingering snow showers. Temperatures in the Lower 48 states Wednesday have ranged from a morning low of 8 degrees at Mt. Washington, N.H. to a high of 90 degrees at Tampa Macdill AFB, Fla.
