AREA FORECAST DISCUSSION
National Weather Service Sioux Falls SD
1104 PM CDT Sun Jun 12 2022
.SHORT TERM...(This Evening through Monday)
Issued at 320 PM CDT Sun Jun 12 2022
The main focus for weather tonight continues to be the potential for
thunderstorms overnight - some possibly severe. There will be mainly
two areas to keep an eye on overnight - one through the Highway 14
corridor northward and then to the south through the central and
lower MO River Valley. One shortwave tracks out of southern MT this
evening with convection developing through northern SD along the
instability gradient/nose of a developing low level jet. It is
possible that some of this convection could graze the northern
portions of our CWA later tonight. With CAPE values running just
either side of 1500 J/KG and effective shear of 40 kts or greater
over that area, severe storms will be possible with large hail and
strong winds - depending on timing of convection as DCAPE decreases
through the night. Another area to watch will be convection which
will develop over western NE in the evening as another shortwave
tracks eastward out of WY. There are differences in the CAMS as to
how this convection evolves and whether it will lift into our area.
Models would suggest that the greater potential for this would be
through the MO River Valley into northwestern IA toward 06Z tonight.
While there will be sufficient instability over this area, effective
shear looks a little weaker over that area, so the severe potential
may be less - though still possible. It appears that strong winds
would be a greater threat with DCAPE a little higher over that area.
Most models indicate any convection over our area to be exiting by
early to mid morning on Monday.
The main story for Monday then becomes excessive heat with an upper
level ridge remaining over the area and a stout southerly low level
flow developing as a surface trough deepens over the Central High
Plains. This will bring increasing low level moisture as dew points
climb into the lower 70s by Monday afternoon as a warm front lifts
through the area. Latest guidance has come in even warmer for
Monday, with locales in the lower Mo River corridor topping out near
100 degrees, while back to the north lower to mid 90s will be the
rule. The combination of high humidity and hot temperatures will
result in afternoon heat indexes of 100 to 105 for a good portion of
the CWA. Because of that, elected to issue a Heat Advisory for all
but east central SD and southwestern MN. There is the potential that
this advisory could be expanded based on future forecasts. It will
become breezy on Monday and Monday night with good mixing and a
tightening surface gradient.
.LONG TERM...(Monday Night through Sunday)
Issued at 320 PM CDT Sun Jun 12 2022
A surface cold front then begins to move across the area by Tuesday.
The cooler air will shift into our western areas first with highs in
the lower 80s over south central SD and the James River Valley,
while to the east upper 80s to lower 90s will be found east of
Interstate 29. May see convection develop over the southeastern
portions of the CWA on Tuesday night/early Wednesday as another
shortwave lifts northward on an approaching upper level trough -
while midlevel warm air advection overspreads the area and a low
level jet develops across the region.
With the upper level trough moving through the Northern Plains for
Wednesday into Thursday, temperatures will cool back down to more
seasonable levels with highs 70s and 80s. Models are in good
agreement on a broad upper level ridge setting up over the region by
the weekend. This will bring much above normal temperatures and dry
conditions to the region for Saturday and Sunday.

.AVIATION...(For the 06Z TAFS through 06Z Monday night)
Issued at 1102 PM CDT Sun Jun 12 2022
Thunderstorms are expected to begin the TAF period, mainly at
KHON as confidence in strong to severe storms has increased for
portions of the highway 14 corridor. The chance for strong to
severe storms continues through about 08Z before activity should
wane below severe levels. MVFR to IFR stratus is still expected to
develop by the early morning hours, now including all TAF sites.
The stratus will continue into the morning hours before lifting to
VFR levels and clearing. Breezy southeasterly winds develop for
the afternoon hours and may continue past sunset for the highway
20 corridor, including KSUX.
