Space Weather Message Code: ALTK08 Serial Number: 39 Issue Time: 2024 May 11 1650 UTC ALERT: Geomagnetic K-index of 8, 9- Threshold Reached: 2024 May 11 1647 UTC Synoptic Period: 1500-1800 UTC Active Warning: Yes NOAA Scale: G4 - Severe NOAA Space Weather Scale descriptions can be found at www.swpc.noaa.gov/noaa-scales-explanationPotential Impacts: Area of impact primarily poleward of 45 degrees Geomagnetic Latitude. Induced Currents - Possible widespread voltage control problems and some protective systems may mistakenly trip out key assets from the power grid. Induced pipeline currents intensify. Spacecraft - Systems may experience surface charging; increased drag on low earth orbit satellites, and tracking and orientation problems may occur. Navigation - Satellite navigation (GPS) degraded or inoperable for hours. Radio - HF (high frequency) radio propagation sporadic or blacked out. Aurora - Aurora may be seen as low as Alabama and northern California. |

Best I could do tonight was a faint pink hue along the northern horizon. Time matched when we had the best chance to see anything, and I verified with a pic at another time to make sure it wasn’t just an iPhone night photo thing.

Nothing here but just saw possible pre dawn surge around 4 am. Might be worth setting an alarm for, it’s not cold or buggy.

Was expecting more of a widespread rain today...we've barely had a trace in Brighton so far. This system seems to be lacking deep moisture or sustained lift or both.

Yep- not really a cold core system- lapse rates aren’t great Must have been better down around Branson. Payne's valley golf courses had a tornado today with zero warning. Also a tornado report in nw mo today. |

 Yes... good low level SRH and low LCL. Good CAPE |

Also a tornado report in nw mo today. Glen Zimmerman reported those weren't true tornadoes. Called them "cold draft" or something like that. |

That was one hell of a deluge. Over 2 inches in one hour. Far too much water in my basement.

It's definitely hit or miss though. But it seems like it finally picked up some deeper moisture today with more widespread convection and showers. |

So while we were all watching the Northern Lights did it come to anyone’s minds we dodged a bullet too. If this flare was directly at us. Might be a different story this week.

Thursday is worth keeping an eye on.
Remnant MCV moving into the area and just enough shear to make things interesting

Yeah, I've been reading about the Carrington event. Insane what that did to telegraph systems, even burning down shacks and shocking operators. You could read by Northern light in New England. It would be very disruptive if such an event took aim at us again. I could be imagining things, but my GPS struggled with city directions over the weekend and my uncle got lost trying to navigate as well. |

.8 inch today IMBY near Bonne Terre, with sometimes heavy rain and thunder, but I drove to Farmington for a Dr. Appt. this afternoon, while raining at my house, and the sun was shining there and roads were dry at that time. Definitely hit or miss.

Remnant MCV moving into the area and just enough shear to make things interesting Models suggest an enhanced band of mid-level winds on the S flank of the MCV...that would be enough to support organized deep convection with sufficient instability. I could see a strong wind threat developing with that...possibly a tornado or two as well. |

Pretty interesting back door storm coming across the area right now.

Using carbon-14 data, there is evidence of an event 10x the strength of the Carrington event in the year 775. Imagine what an event of that magnitude would do to our infrastructure today. |

I'm starting to get concerned about river flooding heading into summer with the current elevated flows, saturated ground and model forecasts showing a spray of shortwaves in the S stream over the next couple weeks. This seems to be a different animal than the last couple seasons that were dominated by dry conditions overall. I'm also getting cool and rainy summer vibes with frequent amplifications in the N branch across the Lakes/NE knocking back the thermal ridge being advected E/NE into our region and an active MCS train. It's been a while since we've had a truly cool summer...2013 was the last one that I recall.

I was trying to figure which event(s) and when broke the back of the drought. |
