The storm is also expected to cause large temperature swings.
Typically we see "bomb cyclones" form off the US East Coast in the form of nor'easters. It seems appropriate for a storm that strong to have bomb in its name, but the word actually refers to a meteorological phenomenon and not the cyclone's explosive intensity.
A Winter Storm Watch for blizzard conditions means there is a potential for falling and/or blowing snow with strong winds and extremely poor visibilities. Winter Storm Watches, Winter Storm Warnings, and Blizzard Warnings are plastered across Northern Colorado, Wyoming, Western Kansas, Nebraska, and South Dakota this morning in preparation for what will be a potent late-season snowstorm.
Snow began to fly about 8:30 a.m. over Greater Bangor, where forecasters now expect as much as 7 inches of fresh powder to make up for the melting in recent days, according to the weather service office in Caribou.
Winds will gust up to 45mph.
The largest April snowstorm on record in the Twin Cities happened just past year when 15.8 inches fell over three days in mid-April.
"We were able to get some (salt) deliveries in across the state and we have been able to cross level a little bit between truck stations so we got what we need", Kevin Gutknecht, with MnDOT, said.
The snow is not the only hazard from the storm.
The sudden change in temperatures, from a high in some cities on Tuesday to freezing conditions on Wednesday, is expected to supercharge the storm with cold air.
Current threat outlook for Thursday evening and night.
"We've got very lucky in terms of we got hardly any rain during the major part of the snow melt", said National Weather Service hydrologist Craig Schmidt. However, over 26 million people are also receiving wind warnings. The high winds are expected to create waves of 15-20 feet or more, which is likely to cause flooding, erosion and other damage along the shoreline. "Road closures will be likely".
Additional flooding in the Plains by the weekend is likely.
While this latest storm may not intensify fast enough to that category, Colorado State Climatologist Russ Schumacher told the Associated Press it "will be near record intensity for April for this area". "Patchy blowing snow could significantly reduce visibility".
