More showery weather is expected across areas of the northwestern quadrant of the West on Friday.A rainy and snowy mix will continue affecting areas of the Intermountain West as a series of disturbances and ample moisture pushes across the region. Snow showers and low snow levels will allow for accumulating snowfall in the Rockies.Just east of this activity, a couple of disturbances from the West will organize over the Plains. These disturbances will spark a mixture of light freezing rain, sleet and snow showers in the Upper Mississippi Valley and Upper Great Lakes. Warm gulf moisture will accompany this system throughout the day and will lead to significant precipitation and thunderstorm development across portions of the Southeast and the Eastern Valleys. Storms in eastern Oklahoma, western and central Arkansas and southern Missouri may turn severe with large hail, damaging winds and perhaps a tornado.Elsewhere, exiting high pressure will provide another day of settled weather condition in New England and the Mid-Atlantic.Temperatures in the Lower 48 states Thursday ranged from a morning low of -25 degrees at Saranac Lake, N.Y., to a high of 89 degrees at Pecos, Texas.UsefulUseful websites: Weather Underground: http://www.wunderground.com, National Weather Service: http://iwin.nws.noaa.gov, Intellicast: http://www.intellicast.com
