The “other Erin” — spooky that OTD in 2007, the arguably most fascinating weather event of my career unfolded: the overland reintensification of TS Erin in OK. I was fortunate to contribute (as the final co-author) to Arndt et al. (2009, BAMS) on this event while at Oklahoma Mesonet

Witnessing strong tornadoes with no shroud of obscuring precipitation around them feels like catching lightning in a bottle.

One of many tornadoes produced by supercell “A” during the May 3, 1999 tornado outbreak. This is tornado A8 as I observed it approaching the municipal airport on the northwest side of Chickasha, Oklahoma. The next tornado in this supercell’s sequence was A9 — the Moore F5.

As mentioned by SPC 20Z Day 1 outlook update maintaining the High Risk — check out the dramatic effect deep-layer ascent has had lifting the capping inversion into veritable irrelevance across the Mid South as shown by WFO Little Rock soundings between 12Z to 18Z. Wowzers!

I measure wind speeds by how much the windows flex here in the Front Range mountains of western BoCo. Windy this evening! #cowx #Boulder

Palmer Divide magic. I got a fantasic aerial view of the persistent remnant deep snowpack on the Palmer Divide while flying near Limon, Colorado this afternoon. Sharp cutoff line between snow and no snow visible too toward the horizon, looking northeast away from the PD. #cowx

Yes.
Exactly like this one, but two-tone — 1) brown and 2) oxidized
