Area Forecast Discussion
National Weather Service Sioux Falls SD
251 PM CST Tue Jan 3 2017

.SHORT TERM...(This evening through Wednesday)
Issued at 250 PM CST Tue Jan 3 2017

The main weather feature for tonight and Wednesday is the episode
of dangerous wind chills. As strong winds gradually abate tonight
and Wednesday with the approach of surface high pressure,
temperatures will be dropping, at least into mid morning Wednesday.
Wind chills are expected to drop to 20 to 30 below zero in most of
the area by morning, and will issue a wind chill advisory through
noon Wednesday. The only area that will not include in the advisory
is the stretch from Vermillion SD and Sioux City IA to Storm lake
IA. It will still be very cold there; just not quite to our
advisory criteria.

Low temperatures under mostly clear skies tonight, or more
accurately Wednesday morning, will vary from 10 below zero over our
best remaining snow cover north, to around zero in northwest IA. The
lack of significant snow cover in most of the area near and south
of Interstate 90 is saving several otherwise frigid degrees on
temperature and wind chill. As for the mostly clear skies,
subsidence in low levels with the approaching high appears to be
dissipating the last few remnants of earlier stratus.

Wednesday will see increasing clouds as a short wave approaches from
central Canada, and a stretch of warm advection and frontogenesis
develops aloft in the tight westerly flow from the central Rockies
into Nebraska. A little light snow could approach or arrive in the
area south of Chamberlain by the end of the day. At this time do not
expect any light snow or flurries further north in front of the
Canadian wave, due to lack of moisture, cold advection aloft, and
temperatures mostly below the favorable dendritic zone.

.LONG TERM...(Wednesday night through Tuesday)
Issued at 250 PM CST Tue Jan 3 2017

Temperatures will be the primary focus throughout the upcoming week.
With a lack of significant snow cover over a good portion of the
forecast area, and indications of at least light winds during the
overnight hours, did not deviate from the blended model consensus
for temperatures too much through Friday. Sub-zero low temperatures
should be common throughout the area both Wednesday/Thursday nights,
and will likely need additional wind chill headlines in some areas
each night. However, will address those as they come, as variances
in location of stronger winds/cooler temperatures will result in a
need in differing locations each night. Thursday looks to be another
day with highs in the single digits, possibly struggling to even top
zero in areas north of I-90 where there is more substantial snow
cover.

Slight warming on Friday before a reinforcing cold front pushes
south through Minnesota and the eastern Dakotas later Friday night
and Saturday. Models coming into better agreement on the timing of
this boundary, and cooling did not appear to be reflected well in
the model blend, so nudged temperatures downward a little Saturday
through Sunday, especially across the northeast half of the forecast
area where we have the snow cover and also where the cold front will
seemingly have a greater impact.

As far as precipitation through this coming weekend, chances appear
very low to non-existent despite a few waves swinging through the
northwest flow aloft. Small chance that some very light snow could
sneak into the Missouri River Valley Wednesday evening as a wave
interacts with stronger mid-level front over Nebraska, but better
chances certainly appear to remain south at this time. Otherwise we
either suffer from a lack of sufficient moisture, or the stronger
forcing slides too far northeast of the forecast area to support
precipitation.

This should change by early next week, as upper pattern changes to
more zonal flow. Effects of this will be two-fold, first shunting
the colder air off to the east, allowing temperatures to return to
near or even above normal for Monday/Tuesday. Second effect will be
allowing for somewhat deeper moisture and a stronger wave to impact
the region by later Monday into Tuesday. 12Z deterministic runs of
the GFS/ECMWF both seem to favor areas to our north for a better
precipitation chance with the leading warm advection portion of the
system, but could be brushed with some light precipitation expanding
southward as the cold front pushes through on Tuesday. However, see
quite a bit of variance within the ensembles on timing/strength, so
did not make any adjustments to blended pops/temperatures at this
time.

.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 1126 AM CST Tue Jan 3 2017

A few patches of ceilings 1-2K feet should dissipate by 21Z.
Otherwise VFR through 04/18Z as surface high pressure approaches.
Northwesterly surface gusts 25 to 35 knots will decrease below 25
knots from west to east 21Z-04/00Z.
