Short Range Weather Forecast

A Change in the Weather Pattern

The Atmospheric River event has ended for the Northwest, and conditions will be drier for a couple of days. A strong cold front in the East may produce damaging high winds in the central Appalachians and critical fire weather threats. Bitter wind chills across Northeast Alaska and heavy snow in the Southeast will continue, and blizzard conditions are expected to develop in far west-central Alaska.

...Widespread record breaking warmth likely throughout the central United States today...

...Gusty winds and fire weather concerns located over the northern High Plains and central Appalachians...

...Scattered showers and lake effect snow forecast across the Great Lakes and Northeast through Friday morning...

A relatively tranquil weather pattern is expected to remain over the Lower 48 through the end of the week, with dominant high pressure located across the southern half of the U.S. and a powerful jet stream remaining over the Northern Tier. As a result, above average temperatures are forecast for nearly the entire country over the next few days. The warmest weather will  occur today as highs soar into the 60s and 70s from the Great Plains to  he Mid-Atlantic. This equates to around 20-30F above normal for early December. Dozens of daily high temperature records could be tied or broken throughout these regions as well. Highs are forecast to remain above normal on Friday, but should begin to cool slightly as a cold front enters the midsection of the Nation. The combination of these warm and dry conditions, along with gusty winds, could lead to dangerous fire weather across parts of the northern High Plains and central Appalachians today.  Additionally, both of the regions have High Wind Warnings in effect to highlight the potential for damaging winds.

Very little precipitation is forecast across the U.S. through the beginning of the weekend. A majority of the activity is likely to occur across the Northeast and Great Lakes as a potent low pressure system swings through southeast Canada. This system and associated cold front will aid in producing showers across the Northeast today. Meanwhile, with arctic air surging behind the cold front lake effect snow is likely to begin overnight into Friday morning across the typical snowbelts of Upstate New York. Light snow is also possible for upslope regions in far northern New England.
