Major Winter Storm to Impact the Mid-Atlantic and Northeast; Inclement Weather in the Pacific Northwest

A major winter storm is expected to bring heavy snow, strong winds, and coastal flooding across the Mid-Atlantic and Northeast that may cause impossible travel conditions and power outages. Blizzard conditions are possible along coastal areas from the DelMarVa Peninsula through southeastern New England. Wet weather and strong winds return to the Pacific Northwest and north-central California. Read More >

Overview

An unusually mild and moist air mass set up across eastern Kentucky in the days prior to February 16th as a wavering frontal boundary laid out along the Ohio Valley. The boundary separated a chilly winter air mass to the north from a mild and very moist air mass to the south. A persistent feed of warm, moist, and unstable air over the boundary, along with potent disturbances passing aloft, sparked rounds of training showers and thunderstorms for much of the day on the 15th. This was followed by a final round of showers and thunderstorms with the passage of a cold front during the morning of the 16th. Rainfall amounts of 2.5 to 4.5 inches were common. Generally speaking, the heaviest and most persistent rain fell between the I-64 and Hal Rogers/Highway 80 corridors although some locations further southeast also picked up on the heavier rainfall amounts. Scattered instances of flash flooding were observed along with many instances of urban and small stream flooding. Eventually, all of this rain led to significant rises on the main stem rivers, pushing river gauge points into action or flood stage on all of the primary rivers -- the Big Sandy, Licking, Red, Kentucky and Cumberland. The worst river flooding was observed along the Kentucky River at Ravenna where Major Flood stage was almost eclipsed and also along the Red River in Clay City where the river reached well into Moderate Flood stage. The flood waters appeared to remain just low enough to spare significant damage to homes, but there were many instances of inundated roads, road damage, and stranded vehicles. A large rockslide also occurred along KY-52 between Jackson and Beattyville.
