The monsoon plume pushed southeast and will clip the southernmost
portion of the San Juan mountains tonight. The rest of the area
will have less storm coverage tonight though moisture content will
remain higher than normal. On Friday the plume starts moving north
and west, with the San Juan mountains and the central CO mountains
east of a line from Glenwood Springs to Montrose getting increased
storm coverage Friday afternoon and evening.

.LONG TERM...(Saturday through Thursday)
Issued at 220 PM MDT Thu Jul 27 2017

The monsoonal plume will remains stationary Saturday but will
break up a bit thus resulting in slightly less storm coverage.
Sunday night will bring the beginning of another fairly strong
surge of monsoon moisture that will affect most of the forecast
area through Tuesday evening.

Strong high pressure over the Great Basin will produce northerly
flow over the area and drier conditions Wednesday and Thursday.


.AVIATION...(For the 18Z TAFS through 18Z Friday afternoon)
Issued at 220 PM MDT Thu Jul 27 2017

Isolated to scattered showers and thunderstorms will continue
over the mountains this evening. This activity will be most
prevalent over the San Juan Mountains. Storms in the vicinity of
KASE, KTEX and KDRO will likely generate outflow winds to 30 MPH.
Otherwise, look for VFR conditions at TAF sites to continue over
the next 24 hours with the exception of isolated showers/storms
over KDRO and KTEX.
