High pressure aloft over New Mexico will begin to gradually move towards the east today, as an upper level storm system digs into California.  This will bring a gradual increase in monsoon moisture across the state through mid week, with isolated to scattered shower and thunderstorms expected across much of eastern Colorado. The increase in moisture will mean a better chance for wetting rains across the region by Wednesday, with an increase threat of flash flooding on area burn scars expected into Thursday. Temperatures will remain above average today, with a gradual cooling trend then expected into the upcoming weekend. Highs will top out in the 90s across much of the eastern plains and 70s and 80s across the high country.   (Please visit http://weather.gov/pub for more information.)
