The National Weather Service is warning of critical fire conditions for most of Kansas as hot, dry and windy weather sweeps the state.

A so-called red flag warning was posted into Tuesday night for all but easternmost Kansas. The warning signals a high potential for fires to spread rapidly and burn intensely.

Weather Service forecasters also issued a fire weather watch for most of Kansas until Wednesday evening as the low humidity, high temperatures and gusty winds are expected to continue.

Temperatures reached the 80s and 90s in all of Kansas by mid-afternoon Tuesday. The next chance for rain doesn’t arrive in most of the state until Thursday night or Friday.
