A powerful mid-level low will continue to power a dynamic low pressure system moving from the Midwest into East Coast over the next couple of days. Showers and thunderstorms will spread across parts of the Mid-Atlantic/Northeast Coasts tonight. Some intense storms may develop around a triple point low propagating from the New Jersey Coast up through the southern New England coast tonight. Therefore, a corresponding Slight Risk (at least 15%) of Excessive Rainfall leading to Flash Flooding is in effect from northern New Jersey through New York City and into southern Connecticut. Heavy Snow will develop over parts of the interior Northeast and central New England tonight and will continue into Thursday before weakening into snow showers on Friday beneath a meandering mid-level low around Downeast Maine. Widespread snowfall accumulations of over a foot are likely across portions of northern upstate New York and central/northern New England, with isolated amounts exceeding 2 feet possible over parts of southern Maine and eastern New Hampshire by Friday evening. Meanwhile, snow showers will occur over the Central Appalachians with accumulations between 6-12 inches possible over the next two days. Another deep mid-level trough will support unsettled weather across much of the West over the next couple of days. Heavy Snow will develop over parts of the Northern Rockies tonight and then the Sierra Nevada Thursday afternoon through that evening. Anywhere between 1-2 feet of snow may accumulate over those areas by Friday night. This system will also generate strong winds over the Central Great Basin Thursday afternoon which will expand into the Four Corners region on Friday.
