National Weather Service Grand Junction Colorado
1040 am MDT Friday Oct 9 2015

Short term...(today through saturday)
issued at 310 am MDT Friday Oct 9 2015

Benign and warmer than normal conditions will persist through
Saturday and beyond. A tilted ridge of high pressure will stretch
from off the West Coast and across central California to the
northern rockies today. A weak upper level wave will pass around
the top of this ridge and across Wyoming during the day. This wave
will brush our northern and eastern edges...with a period of high
clouds as this it passes...and a possible shower in the San Juan
Mountains late in the afternoon.

The upper ridge continues to build over the central rockies through
midday Sat for more of the same warm and dry conditions.

Temperatures will range from 5 to 10+ degrees above normal from
south to north. Overnight lows will also be above normal most
locations. But the difference will generally only be by a few

Long term...(saturday night through thursday)
issued at 310 am MDT Friday Oct 9 2015

A fast moving short wave races across the northern tier states Sunday
and Sunday night. The southern portion of this short wave clips northwest
Colorado...but the "tail" is too dry to generate any showers.
Afternoon breezes may increase a notch...otherwise do not expect
much affect on sensible weather. Slight cooling occurs from Sunday
to Monday.

Flat ridging dominates the weather pattern for the remainder of
the long term. This allows daytime temperatures to run 5-10 degrees above
climatology valleys...and 10-15f warmer than climatology at mountain towns.
The question mark is when does the closed low circulation off the
socal/Baja California coast begin its trek inland. Eventually this becomes a
forecast challenge...but should not impact our forecast area for
the next several days.


Aviation...(for the 18z tafs through 18z Saturday afternoon)
issued at 1040 am MDT Friday Oct 9 2015

Expect no weather impacts on aviation operations across eastern
Utah and western Colorado through the next 24 hours. Cirrus moving
through the ridge will bring partly cloudy skies while winds will
largely be light and terrain driven.
