Area Forecast Discussion
National Weather Service North Platte NE
701 AM CDT Tue Oct 9 2018

.SYNOPSIS...
Issued at 314 AM CDT Tue Oct 9 2018

H5 analysis from earlier this evening had high pressure
located off the coast of the Mid Atlantic states and a second high
pressure noted around 1500 miles west of the nrn California coast.
Between these two features, a broad trough of low pressure extended
from southern Canada through the four corners, into northwestern
Mexico. East of the trough, embedded shortwaves were noted and
extended from New Mexico into eastern Colorado. Satellite imagery
overnight indicated a nice area of thunderstorms extending from the
Big Bend of Texas, north into the Texas Panhandle. Other showers
were present from southwestern Kansas into southeastern Nebraska.
Across western and north central Nebraska overnight, skies were
cloudy with some patchy drizzle. Temperatures ranged from the middle
30s across the northwestern forecast area, to the middle 40s in the
eastern forecast area.

&&

.SHORT TERM...(Today and tonight)
Issued at 314 AM CDT Tue Oct 9 2018

Precipitation chances and snowfall
potential tonight are the main forecast challenges this forecast
period. For today: The shortwave, responsible for showers and
thunderstorms over west Texas currently, will migrate north into
western Kansas this morning. Showers will lift north into southern
and southeastern portions of the forecast area this morning,
spreading north and northwest into the afternoon hours. By late this
afternoon, the main shortwave will lift into western Kansas with
precipitation encompassing most of the forecast area. The shortwave
trough will track through the forecast area tonight, with
precipitation ending in the southern and central forecast area by 12z
Wednesday. As for precipitation type, cross sections taken across
the central and northwestern sandhills indicate a nice area of
enhanced lift extending from Valentine to Imperial late this
afternoon and this evening. Thermal profiles indicate temperatures
cold enough for snow late this afternoon into the evening hours
along and west of a line from Imperial, to Tryon to Ainsworth.
Additionally, the forecast cross sections indicate some possible
convective enhancement from far swrn into north central Nebraska
this evening which would favor a quick burst of snow. Utilizing a
blend of QPF from national guidance and the GFS soln, yielded a
swath of 1 to 3 inches of snow from Imperial to Valentine tonight.
The NAM12 soln seemed too high on its qpf forecast upon
initialization and was disregarded for this fcst. Even utilizing the
fcst qpf from the GFS soln would yield snowfall amounts in the 2 to
6 inch range. Given the warm ground conditions (measured soil temps
in the upper 40s) in these areas, settled on the 1 to 3 inch range
for snow accums. That being said, will leave the inherited winter
weather advisory in effect for the western sandhills and portions of
north central Nebraska, mainly for snow accums of 2 to 3 inches.
Will word fcst locally up to 4 inches to allow for any moderate to
briefly heavy snow band, which may develop.

.LONG TERM...(Wednesday through Monday)
Issued at 314 AM CDT Tue Oct 9 2018

Drier and quieter weather returns on Wednesday as high pressure
starts to build into the region. The exception will be where a few
lingering rain or snow showers are possible across the extreme
northern counties. All rain chances will move out of the region by
Wednesday afternoon with cloudy skies prevailing. There is a low
chance of some patchy frost across much of the forecast area on
Wednesday night as temperatures drop to near or below freezing.
However, have refrained from adding it to the forecast at this
issuance as clouds will help to limit frost development. Will need
to reevaluate frost development at the next forecast issuance.

High pressure will fully engross the region by Thursday keeping dry
conditions around. The next chance of precipitation arrives on
Thursday night. Current thinking is that precipitation will remain
all rain south of a line from Ogallala to O'Neill. North of this
line, a brief change over to snow is possible with minimal snow
accumulations.

Precipitation moves out of the region by Friday morning as high
pressure builds back into the area. Dry weather will continue
through Saturday before the next chance of rain/snow arrives
Saturday night. Accumulations are uncertain at this time as
confidence in the track and development of this system is low.

Temperatures will gradually rise from the mid 30s and low 40s on
Wednesday into the low 50s by Saturday. Colder temperatures return
on Sunday after the cold front passage. Expect highs only in the
upper 30s to low 40s.

.AVIATION...(For the 12Z TAFS through 12Z Wednesday morning)
Issued at 701 AM CDT Tue Oct 9 2018

For the KLBF terminal: Expect ceilings below 1000 FT AGL with
light rain developing after 14z. Rain will continue into the early
evening hours and may mix with snow briefly from 02z to 06z
Wednesday. Visibilities will be in the 4 to 6 mile range when rain
is falling, and 2 to 4 mile range when snow is falling. Ceilings
will begin to improve late tonight with MVFR ceilings expected
after 06z Wednesday. For the KVTN terminal: Expect ceilings under
1000 FT AGL over the next 24 hours. Light rain will be possible
later this morning with snow possible this evening. Visibilities
will range from 2 to 4 miles today and 1 to 3 miles tonight.
