Original post 9pm Tuesday evening:

Welcome to the Super Bowl of Weather.

The deepest low pressure system on record continues to rage with fury over Minnesota.

The storm has already smashed the all time state record for the lowest barometric pressure ever recorded in Minnesota Tuesday.

It also appears to have set the record for the lowest barometric pressure ever recorded in a non tropical storm in the continental United States!

The new final low pressure record will be subject to verification by climate gurus, but reliable observations of at least 28.20″ were recorded by NWS weather stations in Orr and Big Fork in north central Minnesota during the 5pm hour Tuesday. As posted here earlier, these pressure readings are what we would expect to see in Category 3 hurricanes!

The previous record low barometric pressure in Minnesota was 28.43″ in Austin & Albert Lea on November 10, 1998.

Anatomy of a “Land Bomb:”

Check out this amazing loop from SPC of the low rapidly intensifying as it undergoes “bombogenesis” over Minnesota Tuesday to become the deepest low in Minnesota and USA history.

The next phase of the storm features whistling winds and a wintery blast of colder air and wind driven snow. Winter storm warnings are flying from Brainerd into the red River Valley through Wednesday. The season’s first blizzard warnings are up for most of North Dakota.

High wind warnings for sustained winds of 30 to 40 mph with gusts to 60 mph reamin up through Wednesday evening for the southern half of Minnesota including the Twin Cities metro.

As the cold air funnels in temperatures are plunging into the 30s over much of Minnesota. It looks like the first snow flakes of the season will fly in southern Minnesota as well, including the Twin Cities metro area.

Winds will continue to whistle and howl in Minnesota through Wednesday. Here are some of the highest gusts as of Tuesday evening from the Twin Cities NWS.

Huge footprint:

The footprint of this huge bomb of a mid latitude cyclone stretches from Canada to the Gulf of Mexico. Over 1,000 miles of territory from north to south is feeling the impacts of this gigantic system.

At least 21 tornadoes have been reported as of Tuesday evening along the leading edge cold front that tails through the Ohio Valley ionto the deep south.

Some perspective:

This storm will go down as the deepest low pressure system on record in Minnesota. The central pressure is lower than the Halloween Mega Storm, The Edmund Fitzgerald storm, and The Armistice Day Blizzard.

But this forecaster thinks it is a stretch to say it’s the strongest storm in Minnesota history. Central barometric pressure is just one measure of a storms intensity and impacts. Because temperatures were well above freezing and rain rather than snow fell on the front side of the system, the overall effects from this storm are likely to be much less than many of the great Minnesota blizzards.

Still, this amazing and record storm will howl with wind and snow through Wednesday before finally easing gradually Wednesday night into Thursday. Just the latest in a series of incredible weather events in the land of 10,000 storms in 2010.

    Paul, which is the chicken & which is the egg? Does the storm intensity cause low barometric pressure, or does the low pressure cause the storm?

  • Kate Crowley

    hmmm – just another incredible/record setting storm……anyone remember the predictions of what climate change would bring? Better hold onto our stocking caps. The wild ride has just begun.

  • conway kangas

    Please dont go off into that Al Gore scare stuff… There is no Global Warming. Every event does not mean catastrophe. Yes Im from MN and did have to use my wipers on the way to work.

    Paul,

    Your inclusion of NWS text reports in posts would be more readable if you used the “pre” html tag to preserve the Courier font and spacing of the original.

    Oh I so hope someone starts referring to it as a Flurricane. I just love that word! ^^
