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
the 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.
