Area Forecast Discussion
National Weather Service Grand Junction CO
315 AM MDT SAT JUL 30 2016

.SHORT TERM...(Today through Sunday)
Issued at 252 AM MDT Sat Jul 30 2016

High pressure centered over the SW U.S. will continue bringing
hot and relatively dry conditions to the forecast area. A weak
shortwave trough will pass through eastern UT tonight and western
CO Sunday. This slow moving trough will help push the high
pressure to the south and east today and Sunday. This movement
will gradually position the ridge to help draw moisture north and
into the area. Thus there will be a slight increase in moisture
content this evening and overnight. This start of another monsoon
episode will improve a bit more on Sunday as the area heads toward
another moderate monsoonal surge through the week.

.LONG TERM...(Sunday through Friday)
Issued at 330 PM MDT Fri Jul 29 2016

A better surge of moisture will move over the area on Sunday as
the high pressure over the southwest CONUS begins to be pushed to
the east. Therefore the chance for showers and thunderstorms...and
of wetting rain...will increase. Storms will still favor the late
day period...and the mountains. Moisture will then linger through
the week...with some daily fluctuations. But convective activity
will be expected each day...especially during the afternoons and
evenings. However some nocturnal storms will be possible at times
as weak and hard to resolve disturbances are carried by the flow.

Due to the increased clouds/chance of showers...daytime
temperatures will run a little cooler. Nighttime lows will be on
the warmer side for the same reason.


.AVIATION...(For the 12Z TAFS through 12Z Sunday morning)
Issued at 252 AM MDT Sat Jul 30 2016

VFR conditions will prevail the next 24 hours at all TAF sites.
Isolated to scattered thunderstorms are possible over the
mountains from 17Z to about 03Z. This activity may generate
brief, but strong and unpredictable outflow winds at airports in
close proximity to mountains along with a 20 to 30 percent chance
of light rain.
