Click For Summary
Discussion Overview
The discussion centers around an unusually low atmospheric pressure recorded in Kansas, with participants exploring its implications, potential records, and related weather phenomena. The scope includes observational reports, technical analysis of pressure readings, and anecdotal experiences related to recent weather events.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- One participant reports a record low atmospheric pressure of 28.08 InHg in Kansas, noting it as unprecedented for their location.
- Another participant confirms that this pressure would indeed set a new record for Kansas, referencing an external source for verification.
- Concerns are raised about the implications of such low pressure, with one participant comparing it to "Eye of a Hurricane" pressure and inquiring about potential damage.
- Participants discuss a video showing wind patterns over the central US, indicating significant weather activity and expressing surprise at the visual representation of the storm's formation.
- There are mentions of related weather events, including strong winds and a train derailment attributed to the storm, with one participant referencing a Wikipedia entry on wind-related railway accidents.
- Several participants share their personal observations of local weather conditions, including budding trees and blooming flowers, while discussing the effects of the storm in their areas.
- One participant speculates on the historical context of similar weather phenomena, referencing the Bristol Channel floods of 1607 and noting the complexities involved in researching historical weather events.
Areas of Agreement / Disagreement
Participants express a mix of agreement on the significance of the low pressure and its potential record status, but there is no consensus on the broader implications or historical comparisons. The discussion includes various viewpoints and anecdotal experiences without a definitive resolution.
Contextual Notes
Some participants mention the need for calibration records and express uncertainty about the extreme nature of the pressure readings. There are also references to historical events that may not be directly comparable, highlighting the complexity of interpreting weather phenomena.

This would be a new record for Kansas, according to https://www.wunderground.com/resources/pressure_records.asp

The creator of earth.nullschool posted a video on Twitter on Wednesday of the winds over the central US.
He almost never tweets, so I figured something was up.
Very impressive!

It's very weird scrolling through the hours before the storm formed, as it looked to me like total randomness.jim hardy said:
But within something like 6 hours, it was almost perfectly formed.
And it was predicted two days earlier.
I'm sure everyone by now has seen the video of the semi being blown over in Amarillo TX, and the train derailment near Logan NM.
I'm not sure if I've ever heard of a train being derailed by a windstorm.
(google google google)
Oh good grief. Wiki has an entry for everything: List of wind-related railway accidents

Wow. Never thought about it being maybe a record low. Now if I could only find those calibration records.DrClaude said:

Things are okay. I saw no evidence of any damage.jim hardy said:
edit: BTW Any damage your way?

That's an awesome image Om. Thanks for sharing. I'm going to save it in my weather data info folder.OmCheeto said:

Already pulled my barograph chart and put it in "the scrapbook" for Colorado. Don't know that it's the extreme, but impressive, all the same.

I'm seeing signs of the trees budding. Other than that, nothings close to being green.jim hardy said:

Wow ! You certainly had a 'Weather Bomb' !
That would have given a very nasty storm surge on the coast, ~1 cm per mbar plus wind push.
IIRC, something like this has been blamed for the Bristol Channel floods of 1607

{ Take Care when researching this, as both 'old' and 'new' calendars were in use, and a later storm munged some evidence... }
