Fall Storm Dishes Out Rockies Snow, Plains Severe Storms
UPDATED 12:15 PM CDT, October 8, 2011
UPDATED By WeatherBug Meteorologist, Fred Allen
Strong thunderstorms are expanding and streaking across the southern and central Plains, while a new and powerful storm system is poised to deliver another punch of heavy snow along the higher terrain of the Colorado Rockies. If that weren`t enough, more severe weather could erupt across the already hard-hit High Plains this afternoon.
A strong early fall storm is being energized along a stationary front stretching from the Texas Panhandle to the eastern Dakotas to start the weekend. The storm is teaming up with upper-level energy and a clash between warm, moist air over the Plains and much colder, Canadian air spilling across the Rockies. This classic clash of air masses is the net result of a tenuous line of powerful thunderstorms spanning more than 800 miles of the High Plains.
With the storm system already winding up across the Rocky Mountain Front Range, another wave of severe weather could accompany the bulging cold front from Texas to southern Nebraska later this afternoon. While it will likely be sparse, a few of the intense storms will pack a punch with large hail and damaging wind gusts up to 60 mph. The best chance for severe storms today will be in south-central Texas, including the city of San Antonio. Although not related to this storm system, South Florida could also see a chance for severe storms and isolated tornadoes due to a vigorous sub-tropical system spinning nearby.
While it is severe thunderstorms lashing the Central U.S., the storm also poses a winter-side to it across the Rockies. After depositing up to 2 feet of snow across parts of the West, more blinding snow will develop and spread across the Colorado Rockies this weekend. Five to 10 inches of snow will fall at the highest peaks.
Winter Storm Warnings
and Winter Weather Advisories
stretch along the higher terrain of the central and southern Rockies.
As if the heavy snowfall weren`t enough, the cold-nature of this fall storm system will team up with the fresh snow cover and cloudless skies to create bone-chilling temperatures. Freeze Warnings
continue for the higher terrain of northern and central Arizona and western and southern New Mexico. The mercury will dip into the middle 20s to near the freezing mark. The sub-freezing temperatures mean that crops and sensitive vegetation will need to be protected.
