The March 2019 North American blizzard was a powerful Colorado Low that produced up to two feet of snow in the plains and Midwest.

[3] After the storm entered Colorado from its origination in Arizona, the pressure dropped more than 30 mbar (0.89 inHg) and rapidly intensified over the western High Plains.

[4] The severe storm set new all-time record low barometric pressure readings in Colorado, Kansas and New Mexico.

Early on March 12, the system moved onshore in Southern California, subsequently developing into a strong Colorado Low over the Southwestern United States.

The storm's tight pressure gradient allowed wind gusts in excess of 100 mph to develop in the Texas Panhandle.

The strongest was an EF2 tornado, that passed north Holtville and continued to just southwest of Weoka, destroying or damaging outbuildings, homes, convenience stores, power poles, and trees along its path.

In Fayette, 1.75 inches (4.4 cm) was reported while damaging winds knocked down numerous trees and power lines.

[15] Numerous vehicular accidents were reported with at least 1,000 people stranded on the highways, requiring rescue by the National Guard and emergency services providers.

A Colorado State Patrol officer was killed by one driver who lost control of his vehicle on Interstate 76 northeast of Denver.

Most notably, an EF2 tornado spotted near West Paducah, strong enough to rip part of the roof off of the Mount Zion church.

The current record set in 1878 at 971.6 mbar (28.69 inHg) and the storm was forecast to have a slightly lower reading, the equivalent of a Category 2 Hurricane.

[22] The Platte and Elkhorn Rivers had overflowed their levees in the greater Omaha, Nebraska region and some communities were put under a mandatory evacuation order.

[27] In the central parts of Nebraska, large ice slabs were reported to have destroyed crops, and Sub-Zero conditions often hurt livestock.

[30] The City of Pierre achieved full on blizzard conditions (frequent wind gusts above 35 mph/56 km/h producing visibility lower than 1/4 mile/400 metres for at least 3 hours).

At Grand Prairie's municipal airport, a wind gust of 109 mph (175 km/h) tore through, flipping several small airplanes.

[35] The provinces experienced their warmest day in weeks, sparking the risk for isolated severe thunderstorms in extreme southwestern Ontario.
