Event narrative

Mesonet station EW9427 Chester-5NW reported 51 knot wind gust.

Wider weather episode

Strong upper-level ridging persisted and was the dominated weather feature for several days. Record breaking high temperatures, near single digit RH, and strong winds gusts have led to a Red Flag Warning throughout the 4 days. Numerous fires sparked as a result of incapsulated erratic gusty winds associated with isolated dry thunderstorms. The breakdown of the upper-level ridge, onset of strong winds aloft, and the isolated dry thunderstorms was the trifecta that led to an extreme critical fire weather event.
