Area Forecast Discussion
National Weather Service Grand Junction CO
1151 PM MDT Thu Oct 20 2016

.SHORT TERM...(Tonight through Friday night)
Issued at 325 PM MDT Thu Oct 20 2016

High pressure will filter warm, dry air into the region over the
next couple of days. Expect ample sunshine with above normal high
temperatures, though not reaching the near record levels from last

Near freezing temperatures will again be a concern tonight for many
valleys. Clear skies and light winds will support strong radiational
cooling. However, freezing conditions do not look to be widespread
enough to warrant any highlights.

.LONG TERM...(Saturday through Thursday)
Issued at 325 PM MDT Thu Oct 20 2016

Dry weather will persist for the weekend as high pressure remains in
control. Sunday will be the warmest day with temperatures well above
normal under sunny skies and strong warm air advection.

Unsettled weather returns going into the new work week as the ridge
of high pressure shifts east. Southwesterly flow will pull
impressive moisture into the region beginning late Sunday. The GFS
is more aggressive with this trail of moisture, while the Euro is not
as widespread. Regardless, the favored turn of upper level winds
will bring a steady stream of clouds and scattered showers
starting as early as Monday morning with coverage increasing from
west to east. Cooler weather will result, but does not appear to
be as significant as before. Snow levels will remain above 10K
feet with 700mb temperatures bottoming out at 2 to 5 degrees C
Tuesday morning with the Euro being a few degrees warmer.

Models diverge towards the end of the run, but drier westerly flow
looks to set up over the forecast area at the midweek point.


.AVIATION...(For the 06Z TAFS through 06Z Friday night)
