Area Forecast Discussion
National Weather Service Grand Junction CO
332 PM MDT FRI JUL 29 2016

.SHORT TERM...(This evening through Saturday night)
Issued at 330 PM MDT Fri Jul 29 2016

Broad high pressure will continue to stretch across the desert
southwest to the southeast states...with one high circulation
center located to our southwest. This will keep conditions hot
and mostly dry this evening. We have already topped 100F at Grand
Junction this afternoon. Some late day thunderstorms that have
developed will persist into the evening hours. The favored
locations for the storms will be over eastern UT into far
northwest CO...and over the southern mountains. Storms will be
high based with gusty winds but little rain.

Moisture will gradually increase on Saturday for an uptick in
showers and thunderstorms. Many of these storms will continue to
be high based producing little rain...but gusty winds. Hot
temperatures will persist. Look for an increase in nighttime
temperatures Sat night as moisture increases area-wide.

.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 00Z TAFS through 00Z Saturday evening)
Issued at 330 PM MDT Fri Jul 29 2016

Isolated to low scattered showers and thunderstorms will diminish
after around 03z...with just a few storms then possible during
the late night period. Storms...especially this evening will
produce strong gusty outflow winds...but rain will generally be on
the light side. As moisture increases overnight an uptick in
showers and thunderstorms are expected on Sat afternoon. However
VFR is expected to prevail at all TAF sites through the entire
period.
