.SHORT TERM...(Today through Tuesday)
Issued at 514 AM MDT Mon Jun 19 2017

Strong high pressure across the western US will build eastward
and plant its axis over the Four Corners states for the next few
days. Temperatures will be in the upper 90s and challenging 100 in
the low valleys on Monday, then exceeding 100 and potentially
reaching near record temps starting Tuesday. Winds will remain light
and change direction diurnally each day.

.LONG TERM...(Tuesday night through Sunday)
Issued at 514 AM MDT Mon Jun 19 2017

High pressure remains centered over the Four Corners Tuesday and
Wednesday allowing hot, near record temperatures to persist through
Thursday. Overnight Thursday into Friday, a broad trough will dip
into the northern contiguous US allowing the Southwest US high
pressure to shift slightly southward. Winds are anticipated to pick
up a bit over the early part of the weekend due to the pressure
gradient tighten with cooler air to our north interacting with the
hot air in place. Critical fire weather conditions could begin to
develop as early as Thursday afternoon across NE Utah as winds
increase. Conditions over the weekend are expected to remain hot and
dry except for an occasional shower or thunderstorm over the
mountains.

.HYDROLOGY...
Issued at 934 AM MDT Mon Jun 19 2017

A flood advisory has been issued for the Roaring Fork River in
Aspen as snowmelt and tunnel closures upstream have caused the
river to reach bankfull. This advisory will run through Friday
evening.

A number of streams and creeks also continue to run strong, cold,
and high and will continue to do so through the week. The Green
River near Jensen remains near bankfull and CBRFC forecasts
indicate that high flows there will continue.

Where water is running high, river banks may become saturated and
unstable. Lowlands along the rivers may also become inundated with
water.  Remember if you are going to raft, kayak or tube on the
rivers be sure to always wear a life jacket.
