Area Forecast Discussion
National Weather Service Dodge City KS
1100 AM CST Mon Jan 16 2017

...Updated Aviation...

.UPDATE...
Issued at 925 AM CST Mon Jan 16 2017

Another update to add areas of fog to the grids for the next
several hours. Visibility down to 1-2 miles at many locales.
Additionally, accounted for mix precipitation persisting near
Sun City and Barber county. Light snow showers were also
persisting in and near Gray county.

UPDATE Issued at 835 AM CST Mon Jan 16 2017

Ice storm 2017 wrapping up across SW KS. Lingering deformation
light snow across the northern zones will diminish rapidly the
next 3 hours with little additional accumulation. Plan on letting
the ice storm warning expire at noon. That said, please remember
hazards will continue. NW winds of 15-20 mph will severely stress
iced trees and powerlines today, with additional damage and power
outages likely. Models do suggest mid 30s this afternoon, a few
degrees above freezing, which should help to relieve some of the
weight of the ice. Power lines and trees are stressed, and could
collapse at any time. Updated pop/wx grids to account for the
diminishing deformation snow.

.SHORT TERM...(Today and tonight)
Issued at 107 AM CST Mon Jan 16 2017

A strong winter storm may have lingering impacts across portions
of southwest and central Kansas early today as short range models
show a closed off upper level low lifting slowly northward across
central and eastern Kansas through early this afternoon. Meanwhile,
strong H5 vort maxima will continue to cycle around the low as it
pivots northward across the Central Plains, in turn, setting off
further redevelopment of precipitation bands across much of western
Kansas. Also taking into consideration recent radar trends and
expected surface temperatures, freezing rain is likely to linger
across central and portions of southwest Kansas through late this
morning before dissipating. A few tenths to potentially a half
inch of additional ice accumulation is possible. A brief
switchover to snow is still possible across west central and
extreme southwest Kansas toward daybreak as colder air begins
filtering southward across the high plains. Generally light
amounts of snow are possible. Have already extended the Ice Storm
Warning until 18Z. Otherwise, precip chances will end by this
evening with drier conditions taking hold through Monday night.

As for temperatures today, little change to the overall air mass and
prevailing mostly cloudy to overcast skies will limit highs to the
30s(F) this afternoon. Look for lows down into the 20s(F) Monday
night.

.LONG TERM...(Tuesday through Sunday)
Issued at 132 AM CST Mon Jan 16 2017

Dry conditions can be expected through the end of the week as medium
range models continue to show weak upper level ridging moving out of
the Intermountain West into the Western High Plains during the
period.
An extremely weak flow aloft and drier air in the lower/mid levels
moving into western Kansas will limit precip chances across the area
through at least Friday. A warming trend can be expected through the
end of the week as a developing lee side trough creates a west to
southwesterly flow across western Kansas through week`s end, in turn
helping to draw warmer air into the high plains. Well above normal
temperatures remain likely by Thursday with highs reaching the
50s(F).

.AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon)
Issued at 1100 AM CST Mon Jan 16 2017

IFR cigs/vis in stratus and BR/fog will be slow to improve this
afternoon into this evening. Visibility expected to improve some
this afternoon, but IFR cigs will persist several hours past 00z.
Cigs will gradually improve overnight, but MVFR is likely to
persist for quite some time as moisture is trapped in the lowest
layers. Melting ice will also contribute to boundary layer
moisture, with some fog potential overnight. NW winds will
mitigate this some, but included VCFG for now. NW winds will be
gusty at 15-20 kts through this afternoon, stressing iced power
lines. NW winds will diminish to near 10 kts by 00z, and weaken
further to less than 10 kts by 12z Tuesday.
