Area Forecast Discussion
National Weather Service Hastings NE
640 AM CDT THU OCT 6 2016

.SHORT TERM...(Today and tonight)
Issued at 441 AM CDT Thu Oct 6 2016

Upper air and satellite data showing that southwesterly flow
remains in place across the region early this morning, with low
pressure spinning over south central Canada and another shortwave
disturbance pushing through the central Rockies. At the surface, a
frontal boundary is draped through the southeastern half of the
CWA, splitting up the northeasterly winds to the north and
southeasterly winds to the south. Precip-wise not a lot to talk
about currently across our area, but have had some dense fog
develop across portions of our NC KS counties. RAP has had a
pretty good handle on the evolution, suggesting it'll be sticking
around for several more hours. Obs/calls to counties showing 1/4
visibilities around, so did issue a dense fog adv through mid
morning.

Precipitation chances will be on the increase this morning, and
continuing through the afternoon/early evening, as the above
mentioned disturbance over the Rockies continues pushing east. One
question is how much of the area will see thunderstorms, vs just
showers. Thanks to warm air/moisture advection via a strong LLJ,
there has been a gradual northward push of instability. Currently
the brunt of that remains across KS, but some models show
affecting at least a few of our east-southeast NE counties this
morning and into the afternoon. To the west, expecting any thunder
would be isolated at best. Most recent run of models aren't in too
bad of agreement showing near/just after sunrise being when we see
more precip development in our CWA, roughly along the NE/KS state
line. Expecting to see a general east-northeastward shift to
things during the day, with some uncertainty with exactly when we
dry out. Models slowed things down just a touch, so did insert
some PoPs in for this evening.

At the surface, the boundary currently in place doesn't look to
change much through the morning hours, but as the upper level
disturbance pushes closer, a reinforcing front will start moving
through. Because of this, confidence in temperatures is pretty low.
May end up with quite a gradient from NW to SE. Locations near ODX
may struggle to get out of the lower 50s for highs, across the far
SE (south of the front), there is a wide range in models, some
suggest mid 70s is possible, others top it out in the mid 60s.
Later this afternoon, the placement of this reinforcing cold
front will be of interest, as additional thunderstorm development
(and potential for strong/severe) is expected. Similar to the
other day, it's be a close call our far eastern fringe, they may
be affected for a brief time, before action pushes off to the
east. Behind the front, expect increased northwest winds, gusting
near 30 MPH at times.

So then once the precipitation chances shift off to the east of
the CWA this evening, focus for tonight then turns to the
potential for frost. Expecting sky cover to diminish, esp after
midnight, and models are in good agreement showing surface high
pressure settling into the area behind the cold front. Not
expecting winds to become completely calm, but look to diminish to
around 5 mph, esp across western portions of the area. With
cooler/drier air also moving in, temps look to really drop off.
Forecast lows are in the 30s CWA- wide, and decided to issue a
Frost Adv for roughly the northwestern half of the CWA. Not out of
the question that additional counties may be added, will let day
crew get another look at model data and make that decision. At
this point went with counties that look to have the best chance
for frost.

.LONG TERM...(Friday through Wednesday)
Issued at 441 AM CDT Thu Oct 6 2016

After some potential frost, especially north, for Friday morning
as a shortwave trough axis on top of a surface high occurs, the
trough moves east and so does the surface high heading into the
weekend, with near to above normal temperatures expected into mid-
week next week as broad upper level ridging occurs. Another cold
front is introduced in conjunction with another shortwave trough
in the Tuesday night/Wednesday time frame and will potentially
give us another round of cool autumn temperatures. Trends are for
this coming in a bit faster, maybe toward Tuesday rather than
Wednesday. Expect highs to reach the 70s for a good chunk of the
forecast between Saturday and Monday, and perhaps even Tuesday,
depending on how fast the cold front arrives.

Our best shot at rain in the long term will be Sunday night as a
low- amplitude shortwave trough traverses the Central Plains and
a strong low-level jet develops ahead of this trough, with perhaps
the best low-level convergence occurring near our neck of the
woods. We will be dealing with a limited amount of moisture more
than likely, so not going crazy with precip chances at this time.
Will keep mention of thunder as the GFS indicates potential for
600+ J/kg MUCAPE, but not anything necessarily spectacular.

.AVIATION...(For the 12Z KGRI/KEAR TAFS through 12Z Friday morning)
Issued at 633 AM CDT Thu Oct 6 2016

Precipitation chances will be on the increase this morning across
the area as an upper level disturbance pushes out of the Rockies.
Models continue to suggest the potential that this activity could
be scattered in nature around the terminal areas, so continued to
keep mention as VC for now. MVFR ceilings remain in the forecast
for a good chunk of the daytime hours, starting mid-morning,
though confidence in timing isn't the highest. This disturbance
will also usher in a reinforcing frontal boundary today, resulting
in stronger northwesterly winds this afternoon. Gusts near 30 MPH
will be possible. Conditions are expected to improve this evening.
