Doesn't have to be tropical to have impressive spin and plenty of impacts.

Photo from around 6:20 PM last evening (Sun, Sep 20) as a stunning high based supercell spun over the harvest landscape near Newton, Illinois. This supercell was a downburst machine, producing corridors of 60-65 mph winds flattening some ready-to-harvest corn. #ilwx

Radar reconstruction of today's (8/22) plume development from the #HawkFire in Reno, NV. Notable transition to a hydraulic like flow late in the day (~00 UTC) linked to dangerous run into town. We were conducting onsite lidar scans during the transition.

Huge news for Illinois! Folks are seeing the innovation happening in our state with results like the National Science Foundation’s $40M investment in DREAM and PoLARIS to continue the expansion of our burgeoning life sciences and advanced manufacturing industries.

These long flight time balloons are fascinating and open up some real cool autonomous laboratory possibilities where the positioning of these systems could be driven by models and AI based uncertainty quantification.

Most importantly, not only was this the 7th wettest july on record, we got the overwhelming majority of our rain in THREE events. I will be on @wbez.org tomorrow to chat with (the yet to be on @bsky.app ) Sasha-Ann Simons (produced by @mehaahmad.bsky.social ). 9:05am. Tune in. Geek out.

Smoke forecast for the Midwest. Note that HRRR seems to drastically underforecast PM2.5 given that the overwhelming majority of PM in the region is fire origin.

How bad was it? I pulled 16 years of data from the EPA station in Northbrook, IL. Highest PM2.5 on record. Stations across Chicago show a mix of BOTH highest peak and highest daily average or just highest peak.

These are the kind of events that really interest me as they expose the weaknesses in our urban hydrological systems which can start to redistribute runoff instead of removing it.

An example of how quickly driving conditions can deteriorate while storm chasing. As we drove S on IL-45 away from the developing Mattoon-Charleston, IL tornado, the hook of the storm overtook our car. I chuckle, because I know what’s coming.

Here are some probability outlook maps for variables like wind, hail, and tornados. FYI I'm just an amateur weather nerd, and know where to find this data so I can share it. As always, check in with real meteorologists you trust for up to date info through the day.
Severe Weather Outlook:
NOAA places the Chicago area in Moderate (Level 4 of 5) for severe thunderstorms Thursday, with the potential for damaging winds, large hail, and isolated tornadoes.Severe Wind Outlook: The Chicago area has a 60-74% chance of severe hail within 25 miles of any one point with the highest hail threat focused west and southwest of the city.Severe Hail Outlook:
The Chicago area has a 15–29% chance of severe hail within 25 miles Thursday, with the highest hail threat focused west and southwest of the city.Tornado Outlook:  Chicago is located in the yellow shaded area indicating a 10-14% probability of a tornado within 25 miles. The probability of tornadoes is higher to the west of the city.

RCP and SSP scenarios are not emission scenarios. I repeat: they are not emission scenarios. They are radiative forcing scenarios. Forcing = human emissions + the response of the climate system to those emissions You can only back out emissions by making assumptions about climate sensitivity.

ERA5 temperature and precipitation data are now out. For the Lower 48, the Nov-Apr period was not only the warmest Nov-Apr period of record (since 1940-41), but it was also the second driest. A tough combination for sure. 🥵🌵

A wacky moment from yesterday's chase - as a long-lived tornado reintensifies, a satellite tornado develops, retrogrades toward me, and is absorbed into the larger tornado. 4.23.2026 - Braman, OK
