Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 300 PM EST Sat Mar 09 2024 Valid 00Z Sun Mar 10 2024 - 00Z Tue Mar 12 2024 ...Locally heavy rains and strong winds are expected for portions of the northern Mid-Atlantic and southern New England through tonight... ...Heavy wet snow and strong winds are expected across portions of the northern Appalachians tonight through Sunday followed by lake-effect snows across the lower Great Lakes into Monday morning... ...Unsettled weather is expected across the Pacific Northwest and into the northern Rockies as multiple rounds of lower-elevation rain and higher elevation snow arrives... Multiple consolidating areas of low pressure along with the arrival of a couple of cold fronts along the Eastern Seaboard will yield areas of heavy precipitation overnight, and particularly from parts of the northern Mid-Atlantic and into the Northeast. This will include locally heavy rain for portions of eastern Pennsylvania and New Jersey up across southeast New York and into southern New England. As a consolidated area of deepening low pressure approaches and crosses through southern and eastern New England, locally strong winds, especially for New England can be expected as well. Sufficient cold air is expected to filter south into the northern Appalachians to allow for the rain overspreading areas of northern New York and northern New England to change over to snow later tonight into Sunday, and as much as 6 to 12 inches of heavy wet snow can be expected along with strong gusty winds as low pressure lifts northeast across the region. Locally heavier snowfall totals can be expected over the higher peaks of especially Vermont, New Hampshire and Maine. On the back side of the departing area of low pressure, colder air will be surging southeast across the Great Lakes and into much of the Mid-Atlantic and Northeast, and this will gradually favor areas of heavy lake-enhanced snow showers and squalls. Portions of the lower Great Lakes and even the central Appalachians are expected to see locally over 6 inches of snow from the lake effect potential. Elsewhere, unsettled weather will impact the Pacific Northwest and the northern Rockies as multiple fronts and surges of Pacific moisture arrive across the terrain going into early next week. 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. Temperatures will generally be cooler than normal across the Mid-Atlantic and Northeast for the end of the weekend and early next week, but will be much warmer than normal across much of the central and northern U.S. otherwise. Near normal temperatures are expected over much of the West. Orrison Graphics available at https://www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
