Weather Underground Forecast for Thursday, February 20, 2014
A strong winter storm slides across the center of the nation on Thursday, producing moderate to heavy rain and snow showers from the central Plains through the Great Lakes. A low pressure system continues sliding eastward from Colorado through Kansas and Nebraska, into Iowa, Illinois and Wisconsin. Warmer temperatures along the leading edge of this system will create rain showers, turning to snow as cooler temperatures filtering in from the north. Heaviest snowfall totals will range from 4 to 6 inches, while many areas will see freezing rain with ice accumulation up 1 a half of an inch. This freezing rain and sleet will create very dangerous roads and travel conditions across the Midwest so please take caution and travel only if necessary.
To the south, this system will create a cold front that developers over the Lower Mississippi River Valley and eastern Texas, pulling moisture and energy in from the Gulf of Mexico. This will allow for showers and thunderstorms to develop from the Ohio River Valley through the Gulf of Mexico Thursday night into Friday.
Meanwhile, out West, prevailing onshore flow from the Pacific Ocean will continue pushing moisture into Oregon and Washington. This will maintain rain and mountain snow showers throughout the Pacific Northwest and Intermountain West on Thursday.
Temperatures in the Lower 48 states Wednesday have ranged from a morning low of 1 degrees at Antigo, Wis. to a high of 87 degrees at Pecos, Texas
