Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 300 AM EST Sun Mar 10 2024 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.
