Uri: Texas grid failure and losses (statewide figures)
Snowfall overlays: one storm at a time; switch in the layer menu. Ice-storm markers sit at the damage-weighted centre of the hardest-hit states. Off at load, in the layer menu: NWS warnings for the 9 storms in the warnings table (2014–2026); NWS snow reports for the 7 snowfall storms (2009–2026); NWS ice-accretion reports for ice storms #1, #2, #7 and #10 (IEM's NWS storm-report archive holds none for the 1998–2003 ice storms) and January 2026; Uri radar; 1993 Superstorm satellite; Uri grid figures. Reports are preliminary; e.g. WPC's final summary listed 36.0 in at Herman, MI, a later NWS report says 45 in.

OBSERVED: NEXRAD base-reflectivity composite (IEM n0q), one moment as the snow band crossed Texas. Shown from 5 dBZ. Radar composites are archived from 1995, so no storm before then has one.
Infrared cloud-top temperature, Mar 13, 1993 12 UTC

-43°C
-58°C
OBSERVED: 11-µm brightness temperature from Meteosat-3 (east of about 94°W) and GOES-7 (west of it), merged in the NOAA NCEI GridSat-B1 climate data record. Darker blue = colder, higher cloud tops; anything warmer than about -3°C is transparent, so cold snow-covered ground also shows pale blue.
