On This Day in Wx History

1989 – A storm moving out of the Central Rocky Mountain Region spread snow across Kansas and Oklahoma into Arkansas and Tennessee. Snowfall totals of up to 7.5 inches were measured at Winfield, Kansas. Freezing rain on trees and power lines cut off electricity to 24,000 homes in northeastern Arkansas, and 40,000 homes in the Nashville, Tennessee area were without electricity for several hours. 

Almanac

Yesterday’s National Temperature Extremes

High: 84° at both Miami & North Palm Beach, Florida 

Low: -25° at Peter Sinks, Utah

Today’s National Wx Hazards

Some liquid and wintry precip can be found with a system across the Carolinas and Virginias today, with several inches of snow likely for the highest peaks of the Smokies. Meanwhile, a new storm system slowly begins moving into the Pacific Northwest.

Tomorrow’s National Wx Hazards

A storm system continues moving into the Pacific Northwest, with more wintry precip for mountains and rain and freezing rain for the valleys. Some more snowflakes will fly for parts of the central Appalachians and across western New York. Dangerous wildfire conditions persist for southern California.

 Weather Shots

This is a map showing the snowfall from this past weekend’s big Nor’easter that struck the New England area. It was the first Nor’easter of the 2020 season. Snowfall totals of around one foot were expected and that’s pretty much what verified, especially for higher elevations. Warmer ground temps likely kept even more snow from accumulating. Forecasting where the heaviest snow bands will develop with Nor’easters is arguably one of the greatest challenges any forecaster will face, especially since these systems often affect some of the most populated areas of our country.
