US National Weather Summary for October 30,2012

Post Tropical Cyclone Sandy weakened on Tuesday, but brought more active weather to the Northeastern U.S. The center of the storm was located about 120 miles east-southeast of Pittsburgh, Pennsylvania with maximum sustained winds at 45 mph. High wind advisories remained in effect from the Central Appalachians through the Great Lakes, while flood advisories remained in effect from the Upper Ohio River Valley through the Coast. Heavy rain spread further inland through the Ohio River Valley and Midwest. Mid-day rainfall totals for Tuesday ranged from 1.5 to 2.5 inches across the Midwest, while heavy snow showers persisted over the Central Appalachians. Blizzard conditions developed over high elevation of West Virginia and far eastern Kentucky as snow fall totals reached over 6 inches in some places, with wind gusts from 30 to 40 mph. Strongest winds and heaviest rainfall were both reported at Mt. Washington, New Hampshire with mid-day rainfall total up to 3.33 inches and wind gusts up to 107 mph.

To the west, Plains remained mild and dry as high pressure built in from the South. The Upper Midwest saw highs in the 40s, while the Southern Plains saw highs in the mid-70s. Further west, a trough of low pressure approached the Pacific Northwest and pushed moisture onshore from the Pacific Ocean. This created more rain and high elevation snow showers spread across Oregon and Washington.
