Tornado near Eureka, California
A waterspout developed over Humboldt Bay Thursday, January 25th around 4:40 pm and moved through the Woodley Island Marina, dissipating only a minute or so later. Security cameras captured the waterspout moving through the marina onto the island. https://t.co/EIgAPN2BTE

A waterspout moved inland near the NWS Eureka forecast office during the late afternoon hours on 25 January 2018. The brief tornado caused some EF-0 damage (interestingly, it was the only report of severe weather in the US that day, and the first tornado in the Eureka forecast area since 1998).
A comparison of GOES-16 (GOES-East) “Red” Visible (0.64 µm) and “Clean” Infrared Window (10.3 µm) images (below) showed the line of convection as it moved across the area (Eureka and the location of the 0040-0041 UTC tornado are a few miles south-southwest of the airport KACV) — the coldest cloud-top infrared brightness temperatures on the 0037 UTC and 0042 UTC GOES-16 images were -30.7ºC (dark blue color enhancement). Note: there were no western US images available from GOES-15 (GOES-West) between 0030 and 0100 UTC, due to a routine “New Day Schedule Transition” and a 0051 UTC Southern Hemisphere scan.
