Colder temperatures and strong gusty winds to impact the Northeast intoMonday as snow continues to impact the northern Appalachians and portionsof the lower Great Lakes.Unsettled weather is expected to persist across the Pacific Northwestand into the northern Rockies with multiple rounds of lower-elevation rainand higher elevation snow.Fire danger to increase across the central and southern High Plainsfrom very dry conditions, gusty winds, and warm temperatures.A strong area of low pressure will continue to impact the Northeast goingthrough tonight and early Monday with areas of locally heavy snowcontinuing across portions of the northern Appalachians and especially thehigher terrain from the Adirondacks of New York up across the Green andWhite Mountains of Vermont and New Hampshire respectively. A combinationof moisture wrapping around the deep low center and much colder airpouring southeast from Canada will result in locally an additional 6 to 12inches of snow before the snow begins to taper off by later Monday.Meanwhile, the cold air pouring southeast over the lower Great Lakes willyield a continuation of locally heavy lake-effect snow shower activity andsqualls. Portions of northwest Pennsylvania, western New York, and thehigher terrain of the central Appalachians are expected to see a few moreinches of snow this evening and overnight before the activity begins totaper 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 normalacross the Eastern Seaboard and most of the Gulf Coast region. Highpressure will settle down across the region going through Tuesday beforethen gradually advancing offshore. Temperatures are expected to beginrebounding rather quickly for much of the East and the South by laterTuesday as milder air from the Plains and Midwest advances east andcouples with warm air beginning to return north from the Gulf of Mexico.Temperatures over the next couple of days will be well above normal acrossespecially the central and northern Plains and the Midwest which will thengradually advance into the Great Lakes and Ohio Valley. High temperaturesacross portions of eastern South Dakota, Minnesota, Iowa, and Wisconsinare forecast to be as much as 30 to 40 degrees above normal on Monday andTuesday with temperatures approaching or locally exceeding 70 degrees.Some cities will likely be warm enough to see their daily high temperaturerecords either tied or broken.Very warm temperatures over the central and southern High Plains areexpected going through the first half of the week, and this coupled withincreasingly gusty winds and low relative humidity will promote anincreased risk of wildfire activity. In fact, the Storm Prediction Centerhas highlighted large areas of the central and southern High Plains in anelevated to critical fire danger area. This will include the panhandles ofTexas and Oklahoma where devastating fires occurred a couple weeks ago.Meanwhile across the Pacific Northwest, multiple low pressure systemsarriving from the Pacific will bring frequent rounds of precipitationonshore and then farther inland into the northern Rockies early this week.Moderate to locally heavy rain is expected for the coastal ranges withheavy snow over the higher elevations of the Cascades, northern SierraNevada, and the Sawtooth, Bitterroot, and Teton ranges of the northernRockies. As much as 1 to 2 feet of new snow can be expected, withgenerally the heaviest totals expected over the Washington Cascades.
