.SHORT TERM...(This evening through Tuesday)
Issued at 314 PM MDT Mon May 30 2016

Busy here this afternoon with storms over the Panhandle. Expect
this activity to move out of the area late this afternoon and
evening but some showers still possible around the area overnight
as a cold front moves by.

A quieter weather pattern will set up over the CWA over the next
couple days. Continued mild Tuesday under dry northwesterly flow
around an upper low that will be over North Dakota. A few showers
possible over southeast Wyoming near the Colorado border but
chances pretty low. Clearing Tuesday evening and cool with a
surface high settling over Wyoming. Wednesday looking mainly dry
and mild with return flow setting up as the surface high moves
farther east into the plains.

.LONG TERM...(Thursday through Monday)
Issued at 314 PM MDT Mon May 30 2016

A weak shortwave is expected to slide across the U.S./Canadian
border on Thursday. This shortwave will have little if any impact
our region during that day. However, it will bring downslope flow
and warmer temperatures. The warming trend is expected to continue
through the weekend as the upper level ridge builds over the area.
Not looking at much in the way of precipitation except for some
isolated showers and thunderstorms in the mountains.

.AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon)
Issued at 1156 AM MDT Mon May 30 2016

Latest water vapor loop was showing a very distinguished shortwave
anomaly moving through the central wyoming. This feature appears
to be the trigger for the convection that developed during the
last hour. Latest radar loop was showing a thunderstorm moving
south of Cheyenne with some reports of pea size hail. This
thunderstorm will continue to shift east during the afternoon and
will most likely continue its journey into the southern Nebraska
Panhandle. Other scattered storms are possible this afternoon with
the bulk of these storms shifting east into the panhandle. After
this shortwave moves through the flow is expected to turn north
which may cause some lower ceilings to develop towards daybreak.
However, at this point ceilings should generally remain above
MVFR. &&

Minimal fire weather concerns over the next several days with non-
critical fuels and humidities/winds generally remaining outside of
critical thresholds. A cold front will move across the area
tonight keeping temperatures mild through Tuesday. Warmer and
mainly dry weather is expected Wednesday through the rest of the


Issued at 314 PM MDT Mon May 30 2016

The North Platte and Laramie Rivers will continue to run high,
but remain steady or slowly recede over the next couple of days.
Warmer temperatures mid to late week will increase snowmelt once
again. Therefore, expect rises on area rivers, creeks and streams
by next weekend.
