.SHORT TERM...(Today through Monday Afternoon)
Issued at 246 AM CDT SAT OCT 22 2016

Will start this morning with a weak cold front set up near the ND/SD
border, but little in the way of impacts in expected from this
boundary. Another day in the 60s can be expected on southeasterly
winds, with a few readings in the low to mid 70s far southwest. Low
pressure across MT this morning will shift across Lyman County by
00Z, before exiting to west central MN by 06Z Sunday. The nearing
low will allow for some late afternoon shifting and diminishing of
the winds west of the MO River. This will help limit the high
grassland fire danger index values, although RH values will still
fall to 20-30 percent southwest of Pierre.

Northwesterly winds and cooler air will return for Sunday as high
pressure slides overhead. Highs will top out in the mid 50s to right
around 60F. While warm air advection returns Monday, as the sfc high
shifts across MN/IA, highs will only be a few degrees warmer.
Expect highs Monday ranging from the upper 50s to upper 60s
possible, as the 500mb ridge rebounds overhead.

.LONG TERM...(Monday Evening through Friday)
Issued at 246 AM CDT SAT OCT 22 2016

Mid level ridging will be over the Plains Monday night, then gets
dampened as a shortwave trough slides across the region Tuesday and
Wednesday. Northwest flow then sets up as a strong ridge builds over
the Rocky Mountain region on Thursday, with the ridge then pushing
east and over the central part of the country on Friday.

At the surface, the CWA will be between high pressure to the east
and low pressure to the west Monday evening. The low to the west
will gradually push east, bringing precipitation chances to portions
of the CWA late Monday night through early Wednesday. Little in the
way of instability around, so will just mention rain showers at this
time. The system pushes east on Wednesday, with high pressure
returning and bringing dry conditions through the end of the period.

Above normal temperatures will continue through the long term
period, with highs in the mid 50s to mid 60s. Overnight lows will be
in the upper 30s to mid 40s.


.AVIATION...(For the 06Z TAFS through 06Z Saturday Night)
Issued at 1225 AM CDT SAT OCT 22 2016

VFR conditions will prevail across the area overnight and through
the day Saturday. Southeast winds will increase into the 15 to 30
knot range across the west by late morning Saturday, including at
