AREA FORECAST DISCUSSION
National Weather Service Sioux Falls SD
252 PM CDT Thu Oct 6 2022

.SHORT TERM...(This Evening through Friday Night)
Issued at 252 PM CDT Thu Oct 6 2022

FORECAST HIGHLIGHTS:

1. Sub-freezing temperatures most areas tonight and/or Friday night.

2. Warmer air builds back in through first half of next week.

3. Could see a cool-down again late next week.

Still on the breezy side early this afternoon, with temperatures in
the 50s most areas. Dew points currently in the 30s-lower 40s, but
readings in the mid-upper 20s poised just north of the forecast area
as of 2 pm.

Low temperature forecast for tonight is a bit more complex that we'd
like for a couple of reasons. First, center of the surface high will
likely remain off to our northwest until after daybreak, which could
provide at least a light northerly breeze over our area much of the
night. Second, a couple areas of clouds could impact different parts
of the forecast area, in our west/southwest this evening, and in our
east after midnight. That said, given upstream drier air filtering
southward, and persistently dry ground in response to deteriorating
drought conditions, think any clearing will allow for quick drops in
temperatures. We saw this during our brief cool snap last week, when
at least isolated locations fell several degrees below anticipated
lows. Thus have hedged most areas toward the cooler side of guidance
options. Exception to that is in our far east, where aforementioned
cloud cover may hold readings up more in the mid 30s. Again, though,
confidence in the cloud cover is moderate at best, so opting to err
on the side of caution with our headlines tonight. Will convert the
remaining Freeze Watch to a Freeze Warning, expanding a bit farther
south toward Yankton-Orange City. Will blanket the remainder of the
forecast area with a Frost Advisory tonight.

Surface high slides over the CWA on Friday, providing a fair amount
of sunshine and light winds. While this should make it feel a bit
nicer than the temperature would suggest, it will be a generally
chilly day with highs in the upper 40s-lower 50s, about 15F below
seasonal normals.

This will lead into another cold night for this time of year. Not
expecting any issues with cloud cover Friday night, but instead may
see readings in some areas impacted by a light southwest breeze
developing on the back side of the departing surface high. For this
reason, have a bit more elevation dependency to forecast lows, with
coldest readings in the valleys of northwest Iowa where light and
variable winds are more likely for most of the night. Will almost
certainly need additional freeze headlines for some areas tomorrow
night, but given the existing headlines for tonight, will hold off
to avoid confusion.

.LONG TERM...(Saturday through Thursday)
Issued at 252 PM CDT Thu Oct 6 2022

Once we get beyond Friday night, we could still see some patchy
early morning frost over the weekend, but we should see a general
warming trend as the cold upper trough slides east and building
heights begin working eastward into the northern Plains. Models
continue to show a weak wave/back door cool front drop southward
through the area on Sunday, though some disagreement regarding how
far west the wave will track. Farthest west solution would bring
some light showers to our eastern areas during the day on Sunday,
but greater consensus is weaker/farther east with the wave, so will
keep things dry for now.

Begin to see some increase in southerly flow work into our western
counties by Monday afternoon, though Tuesday continues to look like
the breeziest day in the southerly flow, bringing an increased risk
for elevated fire danger.

By late Tuesday-Wednesday, models continue to trend toward solutions
which split the southern stream wave away into the lower West Coast,
while the stronger northern stream track east through Canada and the
northern CONUS. Moisture remains rather limited as this next trough
digs eastward, so will have minimal precipitation chances. Though
timing/strength varies, looks like another shot of colder air will
push into the forecast area by late next week.

.AVIATION...(For the 18Z TAFS through 18Z Friday Afternoon)
Issued at 1221 PM CDT Thu Oct 6 2022

Lingering MVFR stratus over portions of southwest Minnesota and
northwest Iowa to start this TAF period, but satellite trends show
this slowly diminishing in coverage, and anticipate largely VFR
conditions 21Z. However, several model solutions show MVFR stratus
currently over northern Minnesota rotating southward overnight,
which could bring MVFR ceilings back to areas east of I-29 after
07/06Z.

Elsewhere, expect VFR conditions to prevail, with gusty northerly
winds this afternoon diminishing to less than 10kt after sunset.
