Area Forecast Discussion
National Weather Service Sioux Falls SD
1038 PM CDT Tue Oct 9 2018

.SHORT TERM...(This evening through Wednesday)
Issued at 331 PM CDT Tue Oct 9 2018

A strong surface low pressure system currently centered in Kansas
will continue to move north-northeastward this afternoon and
evening. As the center of this low approaches, the pressure gradient
will increase, bringing breezy winds to the area. Given the well-
defined parent upper-level trough, and strong synoptic and
frontogenetic lift with this system, one can expect rain showers to
continue through the evening hours for most locations in the tri-
state area. The forecast calls for an additional inch or so of rain
with this portion of the system, but slightly higher amounts are
possible in areas currently covered by the Flood Watch in northwest
Iowa, where a few rounds of thunderstorms could add to totals this
evening.

Late this evening into the overnight hours, cold air advection in
the wake of this system will cool atmospheric profiles west of I-29.
Robust mid-level omega will support continued lift and precipitation
production in the form of snow. Areas around Gregory,
Chamberlain, and Huron in the central part of SD could see 1-3
inches between midnight and noon Wednesday. Those traveling
westward will want to take note too, as snow totals increase and
chances for slick road conditions increase as one heads toward
central Nebraska, Rapid City, Pierre, and Aberdeen. Winter
Weather Advisories have been issued to cover this threat. Ground
temperatures are still warm, so snow will likely not last long,
but the morning commute especially could be winter-like for the
aforementioned areas.

Snowfall will end during the mid morning over southern parts of SD,
as the forcing wanes and lifts into northeastern parts of the state.
Areas north of I-90 in both SD and MN could see flurries during the
mid to late hours on Wednesday morning, but above-freezing air near
the surface will likely mitigate any accumulations. Temperatures top
out in the upper 30s to low 40s, and combining this with breezy
northwest winds gusting to 30 mph will make it feel winter-like
outside during the day Wednesday.

.LONG TERM...(Wednesday night through Tuesday)
Issued at 331 PM CDT Tue Oct 9 2018

Last remnants of QG forcing in the mid and upper levels departs
northeast of our forecast area Wednesday evening. Low pops are
warranted in our northern zones for perhaps a bit of remaining areas
of light rain or light snow, but honestly do not think anything will
measure. The main forecast alteration for the Wednesday night and
Thursday periods was to increase the wind speeds. Pressure gradient
is tight as surface low pressure strengthens over the northern Great
Lakes, and high pressure building over the western plains. So
Wednesday night and Thursday will remain quite breezy, if not
downright windy, especially east of the James River valley. Because
of the winds and anticipated lingering low clouds Wednesday night,
lows should not fall off too bad, with readings a couple of degrees
either side of 30. Thursday will be very cold for this time of year,
with highs a full 20 or more degrees below normal, and an added
chill due to wind. But, at least it will be dry.

On Thursday night, winds will decrease rapidly. But a big question
remains on the degree of cloud cover. In advance of the next upper
trough, there could be a decent increase in mid and high level
clouds which many models are showing. Right now consensus lows are
projected to be in the upper 20s to lower 30s, which also coincides
with raw model values. Therefore despite the cloud cover, there
could be a decent freeze Thursday night, but again, there is a
question of this due to cloud cover. The upper trough moves through
on Friday with QG forcing showing most of the forcing moving through
our southern zones, with PV at the 1.5 pressure surface quite strong
in central NE, reaching down to 530mb on the GFS. The latest 12Z GFS
and ECMWF have trended a bit further northward with light
precipitation, primarily cold rainfall, all the way up close to I
90. They were showing this several days ago before backing off to a
more southerly track more recently, similar to what the NAM has. But
with a jet streak orientated north to south over the central
Dakotas, our southern zones are placed in a decent left exit region
enhancing broad ascent. For now kept pops in our extreme south
following the consensus over the past few days. If the models stay
with a more northerly trend, we will begin to increase pops further
north to I 90.

Behind the Friday wave, strong warm air advection occurs Friday
night. Blended southerly winds may be a bit light Friday night. At
any rate, the warm air advection will keep lows in the 30s. Then
another cold front screams through Saturday afternoon and evening.
Moisture is limited with this frontal boundary to perhaps northwest
IA where a few showers may occur. But the upper flow is split with
this frontal passage, with one entering the western Great Lakes, and
another digging into southern WY and CO. This front will set us back
on temperatures again with only upper 30s and lower 40s for highs on
Sunday. Normal highs are in the 60s. Along with the cold, the blend
may be woefully underdone on the wind speeds Saturday night and
Sunday behind the cold front. Therefore we will have to monitor that
and raise wind speeds if this trend continues. If things work out
Sunday night with decreasing clouds and winds, we may have our first
fairly hard freeze across the entire forecast area. So between
Sunday night and this upcoming Thursday night, there may not be much
of a growing season left.

There is a lot of model discrepancy by Tuesday, but in general much
below normal temperatures continue Monday and Tuesday with dry
weather.

.AVIATION...(For the 06Z TAFS through 06Z Wednesday night)
Issued at 1033 PM CDT Tue Oct 9 2018

Several concerns continue through the next 24 hours. For tonight
into Wednesday afternoon, rain will continue to stream northward
through the region overnight. Colder air arriving late tonight in
south central could allow rain to mix or change over to snow late
tonight into Wednesday morning. Greatest chances for seeing snow
or a mix will be west of the James River, including at KHON. Low
ceilings and visibility will continue to also impact the region,
with MVFR, IFR and brief periods of LIFR ceilings possible.
Ceilings as low as 300 ft agl will be possible. Conditions will
gradually improve late in the forecast period as the rain exits
the region, allowing visibility and ceilings to improve some, but
likely to remain MVFR through 06z Thursday for most locations.
