Area forecast discussion, Dec 29, 5:44 AM CST, 6 hours 18 minutes before
AREA FORECAST DISCUSSION
National Weather Service Sioux Falls SD
544 AM CST Sun Dec 29 2019
.SHORT TERM...(Today and Tonight)
Issued at 342 AM CST Sun Dec 29 2019
Widespread wintry precipitation will persist over the next 36 hours
as a large cutoff low pressure continues to spin over the central
Plains. Overnight observations have showed a wintry mix of snow,
freezing rain, and sleet for many locations, along with rain in
northwest Iowa.
A shortwave moving through the larger trough today will bring
abundant synoptic lift. Low level frontogenesis will also aid in
increasing precipitation rates, especially just west of I-29 to the
James River valley, which will be solidly under the deformation
zone. Where temperatures aloft are cooler west of I-29, there is
high confidence in moderate to heavy snow at times throughout the
daytime hours. A tightening pressure gradient here will also lead
to notable blowing of snow and lowered visibility. Winter Storm
Warnings are in effect and cover the areas with the highest
potential for significant snow and wind. One corridor worth
keeping an eye on is Flandreau to Sioux Falls to Yankton: A few
high resolution models bring the enhanced lift and precipitation a
bit further east, which would result in one additional tier of
counties seeing higher snowfall totals. Will continue to monitor
where the dry slot sets up during the daytime hours today.
Elsewhere, predominant precipitation type will be tricky initially,
with surface temperatures within 2 degrees of freezing. In southwest
Minnesota, surface temperatures are forecast to remain near 31 or
32, so up to a couple tenths of freezing rain accumulation are
likely before colder air moves eastward later this afternoon
changing precipitation to all snow. Northwest Iowa will remain
mostly rain this morning, although a few sites will remain near 33
or 32, so areas of freezing rain are possible. Colder air pushes
through this afternoon here as well, changing rain to snow.
Winter Weather Advisories cover these areas that are more likely
to see smaller snow totals mixed with a light glaze of ice and
sleet.
Snow continues overnight, but models are in good agreement about
intensity decreasing. Nevertheless, winds will remain breezy,
with blowing snow and reduced visibility causing widespread
difficult travel.
.LONG TERM...(Monday through Saturday)
Issued at 342 AM CST Sun Dec 29 2019
The large weather system is slow to exit the area, with Monday
bringing more light snow and breezy northwest winds. Winter Weather
Advisories currently end mid-morning, but may need extending at some
point if falling and blowing snow continue to cause hazardous travel
conditions. Temperatures will remain below freezing in the lower
to mid 20, keeping daytime melt and overnight refreeze concerns
low.
The rest of the work week look quieter weather-wise. Flurries may
persist into Tuesday, but accumulation is expected to be minimal.
After a cool day with highs near 20 Tuesday, temperatures recover
to near seasonal normals Wed through Fri. Increased cloud cover
looks likely Thursday and Friday as a broad trough moves through,
but the better precipitation dynamics remain over the eastern
CONUS. A strong northwesterly jet next weekend could bring
another round of snowfall; however, confidence is currently low,
with the axis of greatest probability nearer to central MN.
&&
.AVIATION...(For the 12Z TAFS through 12Z Monday morning)
Issued at 539 AM CST Sun Dec 29 2019
Winter precipitation will affect all sites throughout the day,
with heavy snow and strong winds possible at times. The greatest
snow accumulations will be west of I-29. Surface wind gusts will
be in the 30 to 40 kt range. Low cloud decks and low visibility
can be expected to accompany snow over the next 24 hours.
Overnight snowfall rates will decrease in intensity, but snowfall
and wind and the associated impacts from these will remain
through the day Monday.
