Valid 12Z Sun Mar 10 2024 – 12Z Tue Mar 12 2024…Locally heavy rains are expected to sweep across coastal New England
early today with gusty winds……Heavy wet snow and strong winds are expected across northern New
England through today followed by lake-effect snows across the lower Great
Lakes into Monday morning……Unsettled weather is expected to persist across the Pacific Northwest
and into the northern Rockies with multiple rounds of lower-elevation rain
and higher elevation snow…An intensifying low pressure system that brought another round of moderate
to heavy rain across the northern Mid-Atlantic to New England Saturday
night into Sunday morning will continue to track northeast through coastal
New England. Colder air wrapping around the expanding storm will support
heavy wet snow today across northern New England, especially over the
higher elevations of upstate New York, Vermont, New Hampshire and Maine
where winter storm warnings are in effect. As much as 6 to 12 inches of
heavy wet snow can be expected in these areas along with increasingly
strong and gusty winds. Meanwhile, much of the East Coast will be drying
out today after yesterday’s rainfall but blustery winds from the northwest
will usher in chilly air. The cold air passing over the relatively warm
waters of the Great Lakes will promote lake-effect snow showers and
localized snow squalls downwind from the lower Great Lakes toward the
central Appalachians today. The snow showers are expected to linger into
Monday but they will gradually taper off as the huge storm will take some
time to move farther away into the Canadian Maritimes.In the wake of the huge storm circulation, a large high pressure system
will take over and provide a few days of tranquil and dry weather from the
Four Corners eastward through the Great Plains and for the entire eastern
U.S. Cool and dry weather will prevail across the South and the Southeast
including Florida. A warming trend will set in across the northern Plains
today as southerly winds and downslope flow help expanding the warmth
eastward into the upper Midwest by Tuesday when some daily record high
temperatures are possible.Meanwhile across the Pacific Northwest, multiple low pressure systems
arriving from the Pacific will bring frequent rounds of precipitation
onshore and then farther inland through the next couple of days. Moderate
to locally heavy rain is expected for the coastal ranges with heavy snow
over the higher elevations of the Cascades, northern Sierra Nevada, and
the Sawtooth and Bitterroot range of the northern Rockies. The heaviest
snows should be over the Washington Cascades going through Monday where 1
to 2 feet of new snow can be expected.
