Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 400 PM EDT Sun Mar 10 2024 Valid 00Z Mon Mar 11 2024 - 00Z Wed Mar 13 2024 ...Colder temperatures and strong gusty winds to impact the Northeast into Monday as snow continues to impact the northern Appalachians and portions of the lower Great Lakes... ...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... ...Fire danger to increase across the central and southern High Plains from very dry conditions, gusty winds, and warm temperatures... A strong area of low pressure will continue to impact the Northeast going through tonight and early Monday with areas of locally heavy snow continuing across portions of the northern Appalachians and especially the higher terrain from the Adirondacks of New York up across the Green and White Mountains of Vermont and New Hampshire respectively. A combination of moisture wrapping around the deep low center and much colder air pouring southeast from Canada will result in locally an additional 6 to 12 inches of snow before the snow begins to taper off by later Monday. Meanwhile, the cold air pouring southeast over the lower Great Lakes will yield a continuation of locally heavy lake-effect snow shower activity and squalls. Portions of northwest Pennsylvania, western New York, and the higher terrain of the central Appalachians are expected to see a few more inches of snow this evening and overnight before the activity begins to taper off early Monday. In the wake of the gradually departing low center over the Northeast, temperatures to start off the new week will be generally below normal across the Eastern Seaboard and most of the Gulf Coast region. High pressure will settle down across the region going through Tuesday before then gradually advancing offshore. Temperatures are expected to begin rebounding rather quickly for much of the East and the South by later Tuesday as milder air from the Plains and Midwest advances east and couples with warm air beginning to return north from the Gulf of Mexico. Temperatures over the next couple of days will be well above normal across especially the central and northern Plains and the Midwest which will then gradually advance into the Great Lakes and Ohio Valley. High temperatures across portions of eastern South Dakota, Minnesota, Iowa, and Wisconsin are forecast to be as much as 30 to 40 degrees above normal on Monday and Tuesday with temperatures approaching or locally exceeding 70 degrees. Some cities will likely be warm enough to see their daily high temperature records either tied or broken. Very warm temperatures over the central and southern High Plains are expected going through the first half of the week, and this coupled with increasingly gusty winds and low relative humidity will promote an increased risk of wildfire activity. In fact, the Storm Prediction Center has highlighted large areas of the central and southern High Plains in an elevated to critical fire danger area. This will include the panhandles of Texas and Oklahoma where devastating fires occurred a couple weeks ago. Meanwhile across the Pacific Northwest, multiple low pressure systems arriving from the Pacific will bring frequent rounds of precipitation onshore and then farther inland into the northern Rockies early this 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, Bitterroot, and Teton ranges of the northern Rockies. As much as 1 to 2 feet of new snow can be expected, with generally the heaviest totals expected over the Washington Cascades.
