Area Forecast Discussion
National Weather Service Grand Junction CO
348 AM MDT SAT JUN 25 2016

.SHORT TERM...(Today through Sunday)
Issued at 348 AM MDT Sat Jun 25 2016

A short-wave trough continued to drive a cool front across
northwest Colorado early this morning. As a result, showers and
embedded thunderstorms continued over the Flat Tops and portions
of the Park Range. Latest short range models indicated this
activity will likely diminish by daybreak and radar trends seemed
to support this assertion.

Drier air begins to filter over the area in the wake of the trough
as flow becomes more zonal today. This is most pronounced behind
the front which stalls out in the vicinity of the I-70 corridor.
As a result, expect no...or very isolated...moist convection
across the north. In contrast, the San Juan mountains will be
active again this afternoon as moisture lingers there. The central
Colorado mountains will fall somewhere in between and can expect
isolated to low end scattered activity into the early evening.

Drying continues tonight which should bring an end to shower
activity by late evening followed by decreasing clouds. Enough
moisture remains over the San Juan mountains for low end
scattered thunderstorm coverage Sunday afternoon.

Temperatures will run 5 to 10 degrees cooler north of the I-70
corridor behind the cool front. Meanwhile...to the south
afternoon highs will be near those recorded Friday. Sunday`s
temperatures are expected to show little change.

.LONG TERM...(Sunday night through Friday)
Issued at 348 AM MDT Sat Jun 25 2016

The ridge builds back into the region early next week warming
temperatures. Enough moisture remains over the San Juan Mtns to
keep isolated showers and thunderstorms each afternoon. By mid
week moisture filters northward under the ridge and provides more
opportunity for showers and thunderstorms especially over the
southern mountains.

.AVIATION...(For the 06Z TAFS through 06Z Saturday night)
Issued at 348 AM MDT Sat Jun 25 2016

VFR conditions will be the rule for airports across eastern Utah
and western Colorado through the next 24 hours. Scattered showers
and thunderstorms are expected to redevelop over the San Juan
mountains and portions of the central mountains this afternoon.
However, there is little chance for this activity to move over
airports in adjacent valleys. However, strong outflow winds to 35
MPH could impact airport operations. Showers and thunderstorms
will diminish by 04Z/Sunday.

.HYDROLOGY...
Issued at 348 AM MDT Sat Jun 25 2016

Releases from area dams and management of water diversions will
likely add to flow in some rivers and streams. As a result,
waterways across the area will continue to run high, fast, and
cold through the coming weekend. Stay advised of the latest river
forecasts by visiting our website at weather.gov/gjt.
