May 9, 2016 | Katie, Oklahoma Witnessing strong tornadoes with no shroud of obscuring precipitation around them feels like catching lightning in a bottle.

This is an awful development. Unidata has done more for the advancement of the atmospheric sciences and broad technology/scientific collaboration through open data, open-source software, accessible training and educational initiatives — among other things — than I can count.

Due to the current gap in funding from the U.S. National Science Foundation, the NSF Unidata Program is pausing most operations. Nearly all staff will be furloughed until funds from our existing NSF grant become available. For more information, see buff.ly/d2TC1Oy

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 @NWSSPC 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 @NWSLittleRock soundings between 12Z to 18Z. Wowzers!

Well. This is a pretty framable VAD hodo from Paducah, KY at this time. Tornado outbreak ongoing.

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

This has been an utterly fantastic year for auroras! This is just a phone pic that I took of tonight’s display from Brainard Lake in western Boulder County, Colorado. #cowx #Boulder #Aurora

Ethereal red aurora over Nederland in western Boulder County, Colorado last night. I was just about to pack my aurora watching in for the night as this display exploded into view. #aurora #cowx 11 mm, f/4, 9.2 s, ISO 6400
