Weather Underground Forecast for Thursday, November 17, 2011.
Active weather in the East will gradually wind down on Thursday as the cold front affecting the region moves eastward through the Eastern Seaboard and exits the Atlantic Coast. Heavy rain and thunderstorms in the Mid-Atlantic and New England areas are expected to lighten up during the morning hours and end during the afternoon. Meanwhile, showers and thunderstorms in the Southeast will conclude throughout the day.
As this front exits, high pressure in the nation 1/4's mid-section will fill in across the East with drier and cooler weather conditions. Temperatures in the Eastern Seaboard are expected to drop by up to 10-15 degrees on Thursday and Friday. This cool high pressure system will also maintain chances of lake effect rain and snow showers in areas downwind of the Great Lakes during the afternoon and evening hours.
In the West, snow and low elevation rain showers will persist in parts of the Northern Intermountain West and the Northern Rockies, while onshore flow and cold front maintains light precipitation in the Pacific Northwest. Some of this precipitation will spread into northern California throughout the day. Temperatures in the Lower 48 states Wednesday have ranged from a morning low of -18 degrees at West Yellowstone, Mont. to a high of 92 degrees at Edinburg, Texas
