Summer in March

You know the world is about to end when present temperatures are a good 25 to 30 degrees above average and competing with records dating back to the 1800's. As result, it feels more like July than March. Speaking of which, a stale pattern currently over the Midwest having abundant moisture and heating but no significant upper support has resulted in daily isolated pop up showers and storms. A few storms have occasionally been severe with large hail as the primary threat. On that which developed late last night, I tried my luck with lightning but was somewhat unsuccessful. By the time I was on the road, anything worth following was pretty much already collapsing. A few small cells to the NW near Lincoln kicked off a few sparks but not very bright or frequent enough to justify producing a time lapse even though I was shooting continuous.

The trip home however, is when it became interesting...

Another Aurora Bust

Despite limited odds of successfully getting anything, I tried to capture the aurora borealis early Friday morning. It could be seen much further south than usual due to a strong geomagnetic storm occurring at the time. Though my eyes could easily make out the green banding along the northern horizon, my camera had difficulty doing the same due to heavy light pollution and shorter exposures to compensate. Distant low cloud during the strongest period did not help the situation either. Traveling into the country was not an option but hopefully you can make out the greenish tinge. Another CME is forecast to impact the earth Saturday into Sunday.

Wild Goose Chase

In spite of personal success achieved with this latest event, this is not an easy post knowing many people suffered tremendous loss from the same historic system. My thoughts are with all who were directly affected.

Heading out on the morning of Friday March 2nd, I wasn't sure if I should stay closer to home or venture into Southern Illinois where conditions were more favorable for photogenic opportunity. Since it was overcast and somewhat stabilized in the immediate Central Illinois vicinity due to a hail producing severe storm to canvas the region overnight and thinking that the atmosphere might not recover in time, I went south. Below is from Macon Illinois on an elevated cell that may have been producing small hail per the radar capture.





Continuing S, a severe warned cell coming up from near St. Louis taking a similar but more southerly path as the overnight storm caught my attention. Initially it appeared healthy but would weaken on the approach. Positioning myself in Marion County so that the rear flank would go overhead with the strongest area to the NE, the storm would become of lesser interest. In the distance was a large flock of snow geese at rest in a field but out of sight at first. The birds began to stir as the cell drew near and the sound of honks mixed with thunder in the upper levels was surreal. It appeared there came a point where the birds could not handle it anymore and they took to flight in unison. Perhaps it was too late to get out of harms way for they doubled back to land right as the rain curtain swept across the land.

The storm motion was roughly 50 MPH or greater so to switch between lenses while remaining cognizant of the activity was not easy. Though the storm had lost its warning, dime sized hail fell at my location. Video of this encounter is below but wind buffeting unfortunately drowns out much of the goose audio.























I am at the small purple hail core, storm was entirely outflow dominant.



Dropping even further S down towards Mt. Vernon, I rounded I-64 in the hope of intercepting new storms lifting from Carbondale that quickly went tornado warned. These would become the cells of the day however, I was only able to parallel on the backside with no safe or fast option to get below them. Rather than waste fuel as there was simply no keeping up, I abandoned the line at Mill Shoals and went N towards Flora for new severe warnings back along the frontal boundary. Traveling to Indiana was out of the question anyways as this was a work day.

Below is my closest intercept as they too were hauling along at greater than 50 MPH. Once beyond Flora, they also lost their warning with the second image being from over the famous town of Olney Illinois known for their squirrels as white as the cloud tops. After the line cleared per the final image, that was it for the day and the sunny 70 degree temperatures would quickly succumb to chilly overcast skies and strong WNW winds with gusts at times over 40 MPH.
