The forecast Wednesday calls for low humidity, high temperatures and strong winds in some parts of the state, prompting the National Weather Service in Boulder to issue another red flag warning.
The warning will be in effect from 10 a.m. to 8 p.m. for the northern mountains, high valleys and foothills, said Kari Bowen, NWS meteorologist.
The relative humidity will be around 15 percent. A dry westerly flow of winds could bring troublesome wind gusts of between 35 and 45 mph over the Beaver Creek fire in north central Colorado and southern Wyoming, Bowen said.
Winds will be significantly calmer in other parts of the state including in Boulder County, where firefighters are battling the Cold Springs wildfire, she said.
Southwest winds in the Denver metro area will be between 7 to 9 mph, making it less likely that the Cold Springs fire will spread.Rain and thunderstorms are not expected over the Denver area, but they are possible over the Palmer Divide and on the Eastern Plains.
Lightening strikes over the dry Eastern Plains could spark new fires in grass and brush, Bowen said.
A new storm system is moving into the state Wednesday night that will push temperatures down and raise humidity.
There is a 20 percent chance of afternoon showers and thunderstorms in the Denver metro area Thursday. The high temperature is expected to be around 86 degrees.
The low temperature Thursday night will be 58 degrees.
The high on Friday will be around 84 degrees, according to the NWS. There is a 20 percent chance of afternoon rain and thunderstorms Friday. Calm winds out of the southwest will be between 5 and 8 mph.
