Area forecast discussion, Sep 4, 3:00 PM MDT, 2 hours 49 minutes before
Area Forecast Discussion
National Weather Service Pueblo CO
300 PM MDT SUN SEP 4 2016

.SHORT TERM...(This evening through Monday)
Issued at 222 PM MDT Sun Sep 4 2016

Some isolated showers and thunderstorms will continue to be possible
into the early evening hours, with strong wind gusts being the main
threat.  Otherwise satellite images show drier air working into the
area and chances for showers and storms should mostly end by
midevening.  Gusty south to southwest winds will continue into the
evening hours, but will gradually decrease.

Mon should be dry most of the day, however the forecast models are
still showing pcpn developing in the late afternoon hours acrs the
southeast corner of CO and ovr the far southern CO mountain areas.
With sfc dew points expected to be around 60 degrees ovr the sern
corner of CO Mon afternoon, the NAM shows 2000+ j/kg of CAPE in that
area. 0-6km bulk shear is only marginal though, with around 25-
30kts. Breezy south to southwest winds will develop again acrs
most of the forecast area.

.LONG TERM...(Monday night through Sunday)
Issued at 222 PM MDT Sun Sep 4 2016

...Warm and dry week ahead...

Main concerns in the extended will come early in the period.
Moderate shear and instability over the Eastern Plains will lead
to chances for a few svr storms both Mon Eve and Tue afternoon and
eve. Chances will be greatest near the KS border both days. Large
hail up to golf ball size and wind gusts to 70 mph will be the
main threats. Storms on Tue will be a little more widespread given
better upper forcing...but shear does not look as great Tue
afternoon. Highs both days over the Plains will likely be in the
lower 90s as SW flow aloft increases ahead of an approaching
trough.

From Wed onward, flow aloft transitions to more of a zonal pattern
as a series of low amplitude trough move through the N Rockies.
This will result in near zero POPs over much of the area Wed-Thu.
A weak upper low to our south may bring some modest moisture into
extreme southern portions of our area Thu...but POPs look rather
low overall. Temps will remain near 90 over the Plains and in the
70s for the high valleys. The next chance of any widespread precip
does not look to come until next weekend or early the following
week, as a short wave moves in from the NW...but even that looks a
bit iffy at this point. Looks like the first half of Sept will be
quite warm and dry. Rose

.AVIATION...(For the 00Z TAFS through 00Z Monday evening)
Issued at 222 PM MDT Sun Sep 4 2016

VFR conditions are expected at the terminal forecast sites for the
next 24 hours.  Breezy south to southwest wind will continue into
the evening hours and will gradually decrease by late evening.
However, the breezy south to southwest winds will return on Monday
by either late morning or early afternoon, with gusts of 25-30 mph
at the terminal forecast sites.
