ODJ GWS Special: Big Blast Of Arctic Air Expected In US Next Week (Repeating) -- Northeast US Heating Demand To Exceed Normal Tuesday, Wednesday -- Warmer In Northeast US Remainder Of Week Into Next Week -- Cold Air To Dive Southward Into Middle Of Nation By End Of Next Week -- Northeast Could See Cold, First Big Snowstorm By Middle Of Month By Jeff Thompson Kansas City, Dec. 1 (GWS) - While the Northeast U.S. will see heating demands spike above normal for just a couple of days Tuesday and Wednesday before warmer temperatures return the second half of the week into next week, the extended range outlook indicates a significant blast of cold, Arctic air will dive southward into the central sections of the country by the end of next week. The Northeast is forecast to see this cold air move into the region by the week of Dec. 14th with the potential for a significant winter snowstorm in the region Sunday and Monday of that week. The warm weather in the Northeast U.S. will come to a temporary end Tuesday and Wednesday, as cold, below-normal temperatures envelop the region and cause heating demand to rise above normal. Lake-effect snow showers will also be noted throughout the Northeast Monday into Tuesday, while the region will see another quick warm-up with a return to above-normal temperatures the second half of this week. A pattern of near to slightly above normal temperatures and below-normal heating demand will continue across the Northeast U.S. into most of next week, while a significant blast of cold, Arctic air will dive southward into the central U.S. by Thursday and Friday of next week. Arctic air will continue to funnel southward into the central U.S. through the middle of December, before warmer air returns to the Rockies and the Plains by Dec. 16-17 and the cold is pushed into the eastern U.S. This Arctic air will envelop most of the Rockies, the central and Midwestern U.S. and the northern Delta, with the cold air and sub-freezing temperatures forecast to travel as far southward as Texas, Louisiana and the lower Mississippi Valley by Dec. 12-13. Most locations will see temperatures well below normal as a result of this blast of Arctic air. Meanwhile, the cold air will not move into the Northeastern and eastern U.S. until the middle of the month, but ahead of the cold, a strong low pressure area will travel north-northeasterly across the eastern U.S. on Dec. 14-15, producing rain in most areas before changing over to snow with the arrival of the colder, Arctic air on Monday, Dec. 15. The Northeast could see the first major snowstorm of the year with the arrival of this low pressure area by the middle of December, while cold, below- normal temperatures will linger across the region for the first half of the week from Dec. 15 to Dec. 18. Heating demand will soar well above normal in the central and Midwestern U.S. by the end of next week into the middle of December, while the Northeastern U.S. can expect the same above-normal heating demand by Dec. 15 into Dec. 18. |
