The series of disturbances near California will keep afternoon temperatures from soaring over the interior for today and Friday. A building high pressure will approach the Great Basin Friday and will keep any unsettled weather and moisture from impacting the region. The increase in stability will result in clear skies and above normal temperatures as much as 10 to 12 degrees above normal for some locations in the forecast area.
Extended discussion (Monday through Thursday)
Upper level high pressure system over the west will continue to provide dry weather and above normal temperatures for the extended forecast period next week. Temperatures will slowly trend downward into the middle of next week but will continue to be above normal.
