‘Blockbuster’ snowstorm heads east. Then a polar vortex drops in!

❝ After hammering California with rain and snow, a “blockbuster” winter storm is taking aim at the East, where as much as 40 inches of snow could fall over the weekend. Road travel may become impossible in the heavy snow, and flight delays and cancellations are likely.

After the storm heads offshore Sunday, the intense cold will be the main weather story as air straight from the Arctic will roar in, bringing below-freezing temperatures to 200 million Americans…

❝ Snowfall of 12-24 inches is likely to be more common in the heaviest band from the storm, according to the AccuWeather forecast. Blowing and drifting at the height and conclusion of the storm could cause the snow depth to vary by several feet…

❝ After the storm, the coldest air of the season will roar across nearly the entire eastern half of the country by Monday: About 200 million people will wake up to below-freezing temperatures Monday morning, as far south as Florida, according to weather.us meteorologist Ryan Maue. Maue said about 85 percent of the Lower 48 states will see temperatures at or below freezing.

I admit it. The [rare] accumulation of snow and cold we’ve had here in northern New Mexico recently is a PITA – I do not miss New England winters at all.

    An unusually strong late-winter storm is predicted to intensify explosively in the western Plains on Tuesday into Wednesday, unleashing flooding rains, severe storms, raging winds and blizzard conditions in the middle of the nation. https://www.washingtonpost.com/weather/2019/03/11/extreme-storm-central-us-may-generate-blizzard-flooding-severe-storms-midweek/?utm_term=.aa460e943a8c&wpisrc=nl_most&wpmm=1 The zone from Texas north through the Dakotas and Minnesota is expected be hit hardest by the powerhouse storm. It is likely to meet the criteria of a “bomb cyclone,” its pressure dropping 24 millibars in 24 hours between Tuesday and Wednesday afternoon. The lower the pressure and the faster it falls, the more intense the storm. Roaring, potentially damaging winds will affect an enormous area. High-wind watches and warnings have been posted from southeastern New Mexico through Nebraska. Gusts are expected to reach 60 mph late Tuesday into Wednesday, and up to 80 mph to 100 mph in the high terrain, in southwest Texas and southeast New Mexico.
    “This is a potentially dangerous wind event,” warned the National Weather Service office in Midland, Tex. Models project the storm’s pressure to drop to between 970 millibars and 975 millibars as it barrels across Kansas, challenging the lowest pressure recorded in parts of the state.

    (CBS News April 8, 2019): Blockbuster blizzard could impact states hit by “bomb cyclone” weeks ago https://www.cbsnews.com/news/extreme-weather-blizzard-bomb-cyclone-plains-midwest-latest-forecast-path-track-today-2019-04-08/ Only three weeks after a “bomb cyclone” — one of the most intense storms on record — pummeled the Plains and Midwest, another bomb cyclone of similar strength has been forecast. This spring storm seems poised to dump even heavier snow; it could also be followed by another round of significant river flooding.
    Over the past few days, various forecast computer models have shown a blizzard of epic proportions for the north-central Plain States and Upper Midwest. Every time a model is updated, the storm depicted seems to get even more intense. At this point, it seems likely that some of the same areas impacted by devastating flooding just weeks ago are about to get slammed by an historic blizzard Wednesday through Friday.

    A snowstorm will wallop central USA this week, plunging temps as much as 60 degrees in one day https://www.usatoday.com/story/news/nation/2019/10/08/october-winter-storm-snow-central-united-states/3907570002/
    The second major storm in 10 days will dump several inches to 2 feet of snow over the northern Rockies and shock areas farther to the east over the northern Plains with blizzard conditions. https://www.msn.com/en-us/weather/topstories/snowstorm-to-unload-up-to-2-feet-of-snow-lash-north-central-us-with-blizzard-conditions/ar-AAItNEX?page=6
    The storm system will bring another round of early-season accumulating snow to nearly a half a million square miles of the interior United States, and, in some cases, the snow will fall less than 24 hours after temperatures hover in the 50s, 60s, 70s, and 80s F.
    Arctic air will charge southward at the same time a storm moves eastward from the Pacific Ocean over the northern Rockies and Plains during the middle and latter days of this week.
    The arrival of the Arctic air and the strengthening storm will cause weather conditions to change rapidly, whether in the mountains, over the passes or on the Plains.
