.DAY ONE...Today and Tonight

Moisture will slightly increase today from the south allowing an
uptick in showers and thunderstorms especially for the San Juans
and areas south. Remaining mountainous terrain will also see some
convection but just not as widespread. Convection will fire around
noon and continue into the evening hours.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

Showers and storms will continue into the weekend and the first
half of the week as ample moisture will remain in the atmosphere.
A weak disturbance will cause widespread showers and storms
Saturday bringing heavier rainfall with the chance for some debris
flows where the heavier cells set up.

From Wednesday onward, conditions become a bit more tranquil as
moisture content lower inhibiting showers and storms.
