The temperature pattern of warmth in the West and cold in the East that has dominated much of the continental U.S. throughout Winter 2014/2015 will be taken to the extreme over the upcoming weekend.
Updated GFS forecasting models show the extremes of these temperatures as the jet stream creates a ridge that divides the country into two.
Cold temperatures are also forecasted to extend far south as a freeze is forecasted for the region Friday night and again on Saturday night.
According to AccuWeather.com, the worst of the cold is forecast to focus on the Tennessee Valley Friday night with temperatures dropping down into the 20’s in cities such as Paducah, Kentucky, and Nashville, Tennessee.
Meanwhile, record-breaking warmth is forecasted over the weekend in the West with parts of California and Arizona seeing triple digit temperatures.
According to Weather.com, the warmth extends out of the Desert Southwest into the Pacific Northwest and Rockies through Friday as a ridge of high pressure slides into the West. Above-average temperatures will then move across the West and into areas of the Plains over the weekend.
While the below average temperatures are likely to create heating demand in the East, it is likely that the above average temperature will generate cooling demand in the West.
California is the second largest consumer of natural gas – mostly for power generation. Therefore, any increase in cooling demand could increase natural gas consumption.
