…Series of clipper systems to bring rain and snow showers to the Great
Lakes, Appalachians, and Northeast through the early weekend…
…Above to well above-average temperatures expected to persist for most
of the country to end the work week…
A clipper system moving through the Great Lakes and Appalachians/Northeast
will bring unsettled weather across the region today (Thursday). Scattered
light to moderate rain showers can be expected across portions of the
Mid-Atlantic and Carolinas while a messy mix of rain and snow is expected
for higher elevations of the Appalachians as well as further north into
the interior Northeast/New England. Some light to moderate snow totals can
be expected for higher elevations of Upstate New York/New England as well
as locations closer to the Canadian border that will see mostly snow. Some
lake-enhanced light to moderate snow totals are also likely downwind of
Lakes Erie and Ontario. Precipitation for most locations should come to an
end by Friday evening, lingering longest for the Appalachians and Interior
Northeast. Then, on Friday, another clipper system will drop southward
from Canada and into the Upper Great Lakes bringing a swath of moderate to
locally heavy snowfall. The system will swing eastward across the Lower
Great Lakes/Interior Northeast by Friday evening bringing additional light
to moderate snows. The highest totals are most likely across higher
elevations of Upstate New York and downwind of Lake Ontario. Elsewhere,
the country will be mostly dry. A low pressure system moving through
southern California may bring some showers and thunderstorms by late
Friday/early Saturday.
Most of the country will continue to see above to well above average
temperatures and mild conditions to end the work week. In the East,
forecast highs Thursday generally range from the 30s and 40s in New
England, the 40s and 50s in the northern Mid-Atlantic, and the 60s and 70s
in the southern Mid-Atlantic into the Southeast. A cold front passage will
bring highs down by about 10 degrees on Friday, but this will still be at
or a bit above average for most locations. For the central U.S., forecast
highs the next couple of days range from the 40s and 50s across the
northern Plains and Great Lakes; the 50s and 60s for the central Plains,
Middle Mississippi Valley, and Ohio Valley; and the 60s and 70s for the
southern Plains. Into the West, highs are expected to be in the 50s and
60s for the Pacific Northwest and Great Basin/Interior West, the 60s and
70s in California, and the 70s and 80s in the Desert Southwest.
