NEXRAD in Central Illinois showing three body scatter off of moving freight trains this morning. Anomalous propagation from shallow cool airmass keeps the beam low, and radar energy is bounced repeatedly between the high reflectivity train cars, making it look like it is coming from further away.

Working on an analysis of radar coverage for the State of Illinois, including beam height and wind farm contamination relative to recent severe weather reports. 2026 has been a year in Central Illinois!

Interactively drill down to see connections between islands, sea surface temperatures, topography, and land cover and precipitation. Have fun!

NEXRAD vertical wind profiles at KILX (thx @plustssn.autumnsky.us) reaching ridiculous levels - question for Champaign-Urbana will be whether the environment can recover from earlier crapvection...sounding at 3 pm CDT coming up!

Need to get them a sounding system…

I don't recall seeing such a strong WAA signature in the wake of an MCS...

@climasillinois.bsky.social students launched a sounding at 20:15z from the UIUC campus

Having fam in upstate NY and living in Illinois often means an extended 48 hour period of nowcasting 😰

Wish to know where it rains most frequently or most heavily from our most accurate spaceborne techniques? Look no further, NASA’s TRMM and GPM precipitation radars to the rescue! huggingface.co/spaces/snesb...

Finding toxic waste in Niagara Falls shouldn’t be a surprise, as industry went wild there for decades. Love Canal on repeat. But will we have an EPA that can address these? Reminder that corporations (and now gov’t?) really don’t have your interests in mind. www.audacy.com/wben/news/lo...

Select a satellite mission (GPM, TRMM, or combined) and a precipitation variable such as rate, frequency, or intensity, then view an interactive world map that visualizes the chosen climatology wit...
