...A fast-moving low pressure system expected to spread heavy rains and
potential severe weather across portions of the Southeast today...
...Below average temperatures continue for the Pacific Northwest and much
of the East over the next two days...
...Heavy snows over the Cascades and into the northern Rockies today and
Wednesday will be followed by widespread snow across the northern Plains
A fast-moving low pressure system moving across the Deep South will bring
a quick round of heavy rain and the potential of severe weather through
the Southeast today into tonight. The rain will exit the Southeast U.S.
coast later tonight but a period of heavy rain with increasing winds could
clip the eastern shores of North Carolina early on Wednesday as the low
pressure system is expected to intensify into a massive storm off the East
Coast. This storm will also be very expansive in size and will have some
influence in keeping light amounts of wet snow across northern New England
through Thursday morning.
Large portions of the country over the next two days will be in a cool
spring weather pattern as upper level lows are anchored across the Pacific
Northwest/southwest Canada and over the Northeast. These upper lows will
keep temperatures below average from the Pacific Northwest, northern
Rockies and into the northern High Plains, as well as across much of the
eastern U.S. The exception will be along the Gulf coast into Florida
where much above average temperatures will continue Tuesday before cooler
temperatures move in behind a cold front on Wednesday. Above average
temperatures also likely from southern California, through the Southwest
and across much of Plains over the next two days.
Following the departure of the low pressure system across the Southeast
into the Atlantic on Wednesday, the focus of active weather will shift to
the northwestern U.S. where the aforementioned cold upper lows will
support heavy snow along the Cascades of Washington & Oregon into much of
the higher elevations of the northern Rockies. Snow totals over the next
two days may be in the 1 to 2 foot range across these areas. By Wednesday
night into Thursday, a complex interaction of the upper lows with cold air
intrusion from Canada will result in an increasing threat of snow
expanding eastward from the northern High Plains toward the upper Midwest.
