Area Forecast Discussion
National Weather Service Cheyenne WY
1125 PM MDT MON SEP 5 2016

.SHORT TERM...(This evening through Wednesday Night)
Issued at 257 PM MDT Mon Sep 5 2016

Tonight...Few showers trying to develop across our northern counties
in a low level convergence zone area. NAM indicating increasing
areal coverage thus have painted isolated to scattered showers and
thunderstorms this evening east of a Douglas to Kimball line.
Isolated showers continue after midnight along with low level
saturation east of I-25...thus expect areas of fog to develop.

Tuesday...While southwest flow aloft continues, low level upslope
continues east of the mountains, and with a shortwave moving
overhead in the afternoon, isolated to scattered showers and
thunderstorms expected east of a Douglas to Laramie line. A few
storms may become strong per CAPE and shear and with the Storm
Prediction Center marginal risk area.

Tuesday night...Showers slowly decrease in areal coverage from west
to east with more areas of fog forming across western Nebraska as
the boundary layer saturates.

Wednesday...Flow aloft turns westerly, drying out the low and mid
levels and producing a dry and warmer day with more sunshine.

Wednesday night...Quiet night with westerly flow aloft and limited
low and mid level moisture, thus no precipitation.

.LONG TERM...(Thursday through Monday)
Issued at 257 PM MDT Mon Sep 5 2016

Two separate cold fronts will continue chipping away at the warm
late Summer temperatures during the long term. Flow will be zonal
Thursday ahead of an approaching shortwave trough. Models tend to
underdo the warmth and wind speeds of the prefrontal air mass. As
such, will need to keep an eye on Thursday as the next potential
critical fire weather day. Cold front #1 arrives Thursday night.
Moisture will be very limited, so do not expect any precipitation
from this initial front. Temperatures will cool behind it,
however. High temperatures will be 5-10F cooler Friday compared to
Thursday. Light winds and clear skies will yield a cold night
Friday night. May see temps approach freezing in some lower
valleys west of the Laramie Range. Flow once again turns zonal
over the weekend, advecting back in warmer temperatures and again
returning fire weather concerns most likely on Sunday. Front #2
arrives Sunday night returning precipitation chances into Monday.
The air mass behind this second front appears to be cooler than
the first, likely cooling hi temps back into the 60s for Monday.

&&

.AVIATION...(For the 06Z TAFS through 06Z Tuesday evening)
Issued at 1125 PM MDT Mon Sep 5 2016

Isolated showers and a few tstrm over the Panhandle early in the
period.  MVFR/IFR cigs along with some fog expected to increase east
of the mtns overnight in moist upslope flow with low cigs likely
hanging on for much of the day Tuesday over the Panhandle.

&&

.FIRE WEATHER...
Issued at 257 PM MDT Mon Sep 5 2016

Critical day looks likely on Wednesday as wind gusts progged to
exceed 25 mph west of I-25, with humidities falling to near 15
percent in the afternoon. Low humidities continue Thursday and
Friday.
