A deep and dynamic mid-latitude cyclone will organize over the Central/Southern Plains this morning. Snow will develop in the Plains today and advance into the Midwest tonight and Tuesday. Bursts of heavy snow may accumulate up to two inches in an hour, and result in hazardous travel. A heavy, wet snow will also develop in the interior Northeast Tuesday afternoon and night. A blizzard is expected in the Plains of northeast New Mexico, eastern Colorado, the Oklahoma and Texas Panhandles, western Kansas and southwest Nebraska. Wind gusts as high as 60-70 mph will create ferocious blizzard conditions with whiteouts. Travel will become extremely dangerous to impossible. If you must travel, pack a winter survival kit as wind chills will plummet below zero. There is an Enhanced Risk of Severe Thunderstorms across the central Gulf Coast tonight into early Tuesday morning. Severe thunderstorms capable of producing strong wind gusts and tornadoes are expected from southeast Texas across the central Gulf Coast this afternoon into early Tuesday morning. This Enhanced Risk of Severe Thunderstorms shifts into parts of southeastern Alabama, northern Florida and parts of the Carolina Piedmont/Coastal Plain on Tuesday. Very strong and damaging winds as well as a few tornadoes will be the main threats. Widespread and potentially significant river and flash flooding are likely for the central Gulf Coast and Eastern U.S. through early Wednesday. Powerful onshore winds will lead to widespread coastal flooding along the eastern Gulf Coast and much of the East Coast. Significant coastal flooding is likely, especially on the Mid-Atlantic coastline, including tidal rivers and bays. There's a Moderate Risk of Excessive Rainfall leading to Flash Flooding over parts of southeast Louisiana, southern Mississippi and southwestern Alabama today where several inches of rainfall may accumulate. The Moderate Risk of Excessive Rainfall shifts into the Mid-Atlantic on Tuesday between northern Virginia, up the I-95 corridor and into western Massachusetts, where existing snowpack from the recent snowstorm may cause additional runoff concerns. Widespread wind gusts in excess of 50 mph are likely in the eastern Gulf Coast, Central Appalachians, much of the East Coast and New England. Prepare for power outages. Elsewhere, yet another pair of powerful winter storm systems will cross the Pacific Northwest tonight and Tuesday night with several feet of heavy snow and strong winds expected across the Cascades. Blizzard conditions are likely. Snow levels rise to around 5000' tonight with an atmospheric river, but will quickly fall to between 1500 and 2500 feet behind a cold front on Tuesday, leading to considerable impacts for many mountain passes with the second storm Tuesday night. Over a foot of snow is likely (70-90%) in the higher elevations of the Northern Rockies on Tuesday and Wednesday. Kebede Graphics available at https://www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
