AREA FORECAST DISCUSSION
National Weather Service Sioux Falls SD
536 PM CST Sat Jan 1 2022
.SHORT TERM...(This Evening through Sunday)
Issued at 314 PM CST Sat Jan 1 2022
Clearing skies from west to east this afternoon is giving us a
glimpse of patchy snow cover via satellite across our coverage area.
Snow earlier today along and south of Highway 20 struggled with
saturation, and thus just a few light snow reports from KSUX and
KSLB, as well as a public report of some flakes in Ida Grove. Expect
any light snow/flurry activity to continue to diminish through the
mid to late afternoon hours (if it hasn't already). The main story
today has been the cold - with most sites single digits either side
of zero as of 21z. Northerly winds have been around 10 to 20 mph.
Wind chills have increased enough that the earlier Wind Chill
Warning and Wind Chill Advisory have been allowed to expire;
however, a second Wind Chill Advisory is in effect through tonight
for areas where wind chills have been and will remain near/below -25
degrees F.
Regardless of if a Wind Chill Headline is in effect for your
location tonight, limit cold exposure and dress in plenty of layers.
Lows tonight fall into the single digits and teens below thanks to
clear skies and surface high pressure, with the coldest temperatures
likely in areas with new snow. Winds are expected to lighten through
the night as high pressure becomes more centered over our area, but
with temperatures that cold, it won't take much for wind chills to
fall. Expect wind chills area-wide to be in the teens and 20s below
zero. Subsequent shifts will want to monitor both temp and wind
trends tonight, as slightly colder temperatures or stronger winds
may drop wind chills in other areas to advisory criteria
(especially with new snow).
Upper ridging and warm air advection (WAA) begin to move into the
area Sunday. This will help begin to moderate temperatures a bit,
especially for south central SD where WAA and southerly surface flow
may help to warm this area closer to average. One caveat with highs
in this area would be that if areas to the south/southwest have
received more snow cover, than the southerly surface winds would not
have much of a warming impact. Regardless, expect clear/mostly clear
skies with highs from the teens and lower 20s (for those with new
snow) to near 30 (south central SD).
.LONG TERM...(Sunday Night through Saturday)
Issued at 314 PM CST Sat Jan 1 2022
Upper ridge and WAA continue into the early part of next week. Lows
Sunday night will be in the single digits (snow pack) to near 20
(south central SD). Although it may take a bit more time for areas
with some snow to recover temperature-wise, do expect the area to
return to near/above normal for highs Monday and likely Tuesday.
This will put most of the area with highs in the 30s, colder
(possibly 20s) for areas with snow and warmer south of Highway 18
(with some reaching into the 40s). Temperatures on Tuesday could be
in jeopardy if cold air advection (CAA) with the next feature moves
in more quickly.
Despite a bit more agreement than yesterday's runs, deterministic
and ensemble data continue to vary in resolving the next low
pressure and trough working through the area late Tuesday through
Wednesday. Issues arise from the timing to the location, with the
GFS continuing to trend a bit more to the southwest and the EC a bit
more to the northeast. Could see two separate chances for
precipitation, with one to the northeast of the area and one to the
southwest given the current track of the forcing mechanisms (WAA to
the northeast late Tuesday, and with the jet further southwest
Wednesday afternoon/evening). Ensemble guidance across the models
does hit at some light QPF across the areas, and thus think that
portions of the area could see some light measurable snowfall.
Trends will continue to be monitored, but have left the NBM as is
for now given range of solutions.
The bigger story behind this low will likely be the robust CAA and
strong surface high pressure that returns for the second half of the
week. Comparison of ensemble guidance to climatology shows that
temperatures at numerous levels of the atmosphere are on the coldest
side of climatology (near and below 2.5% of climo). Additionally,
surface high pressure comparison shows that Thursday's high pressure
is above the 90th percentile. To summarize - very cold air and
strong surface high pressure will lead to a return to well below
temperatures for the middle to end of next week.
Upper ridging and near normal temps look to return to start next
weekend, with models hinting at a wave moving through.
