UPDATE 3/18: The Colorado record has (kind of) been confirmed.

Today, March 13, 2019 will go down in history as the most intense storm ever observed in the Colorado, New Mexico, and maybe Kansas area. At 18Z, the WPC has analyzed the Low over SE Colorado at 968 millibars (28.58" Hg). 971 mb was measured at Lamar, CO. This is likely lower than anything recorded in Colorado (record 975.8), New Mexico (record 974.6), possibly Kansas (971.6).

The coverage area of the storm was impressive -- some called it an "inland hurricane" -- spotter reports numbered over 2,000 and there were hundreds of AccuWeather AccuCast reports about the storm as well. There were over 500 severe thunderstorm, tornado and flood warnings issued that week.

The storm wreaked havoc for at least three days, starting with some snow in the Rockies and Arizona and tornadoes in Texas on March 12th; on March 13th, the record low pressure readings were set, blizzard conditions overtook the Rockies and South Dakota, and flash flood warnings went out. For Day 3, March 14th, a major tornado outbreak hit Alabama while severe thunderstorms tracked through the Great Lakes and Midwest, while high winds gusted behind the storm from Nebraska to Minnesota.

I also made this mosaic of hundreds of maps and photos from the storm.
