Afternoon RHs will be observed closer to 5-10% with very little help from overnight recoveries as MaxRHs peak between 15-45%. Near to slightly above normal temperatures will prevail through the next few days. Note...Additional Fire Weather Forecast information can be found in the Area Forecast Discussion.
