Heavy snow continues for portions of New England, the northernMid-Atlantic, and Appalachians.Clipper-like system to bring rain and snow showers to the Great Lakes,Ohio Valley, and Appalachians Monday to Tuesday.Much above average, mild temperatures for late January for much of the country.Moisture flowing inland around a low pressure system moving through theMid-Atlantic today will continue to lead to precipitation chances from theOhio Valley/Lower Great Lakes eastward through the Appalachians,Mid-Atlantic, and New England. The most impactful weather will be throughportions of southern New England west through the Catskills, Southern Tierof New York/northern Pennsylvania, and southward through the Appalachianswhere accumulating snow is expected. The snow will likely be heaviest forportions of Southern New England and higher elevations of the southernAppalachians, where Winter Storm Warnings are in effect for totalaccumulations generally between 4-8", with more moderate totals closer to2-4" elsewhere. Otherwise, rain showers will be possible for the OhioValley and southern Mid-Atlantic with a chance for a light wintry mix forthe Lower Great Lakes, with little to no accumulations anticipated.Precipitation should taper off from southwest to northeast through the dayMonday as the systems moves out into the Atlantic.Conditions across the rest of the central and eastern U.S. will remainmostly dry. Some light to moderate rain/snow showers will dropsoutheastward from the Upper Midwest through the Great Lakes and into theUpper Ohio Valley and Appalachians late Monday night and into the dayTuesday with a clipper-like system. Any accumulations should remainlimited to a few inches of snow for higher elevations of the centralAppalachians. The West will be quiet too besides for some shower chancesin the Pacific Northwest as a series of Pacific waves pass by. A moreimpactful Atmospheric River event is expected for the West Coast laterthis week just beyond the current forecast period, though there is achance some heavier rain could begin for portions of northern California/southwestern Oregon Tuesday evening. Broad upper-level ridging over the West beginning to shift/expand eastward will keep high temperatures above average by 10-20 degrees for most of the country early this week. The greatest anomalies will be in the Northern/Central Plains where highs in the 40s, 50s, and even some low 60sare upwards of 25-30 degrees above average. Highs along the West Coast will be quite anomalously warm too, with 60s for the Pacific Northwest/northern California and 70s for southern California. Highs in both locations may tie/break daily records Monday and Tuesday. Highs will remain cooler than average for portions of the Southeast/Florida as conditions are slower to moderate following a cold front passage this weekend, with highs mostly in the 50s and 60s.
