Significant and Catastrophic Flooding in the Pacific Northwest; Very Cold Temperatures in the Northern Plains

The atmospheric river over the Pacific Northwest will begin to subside today, but lingering rainfall will exacerbate ongoing catastrophic major river flooding, and landslides will continue across portions of western Washington and northwest Oregon for several days. Arctic air will plummet southward into the Northern Plains today, bringing cold air in the single digits to the region by Friday. Read More >

Overview

Scattered light showers occurred during the late afternoon of November 1st, 2018. A landspout tornado developed from one of these showers near the town of Iberia, MO causing some minor tree damage. (A landspout tornado is defined as a tornado that does not arise from organized storm-scale rotation and therefore is NOT associated with a wall cloud or a mesocyclone. Landspouts typically are observed beneath cumulonimbus or towering cumulus clouds often as no more than a dust whirl.)
