.DISCUSSION...
Issued at 143 PM CDT Wed Aug 13 2025

Skies are mostly clear this afternoon with a few areas of
scattered clouds around 3000 ft. WPC has analyzed a stationary
front northwest to southeast just west of our area. A shortwave
currently over north-central Wyoming will move into western
South Dakota this afternoon triggering storms along this
stationary boundary. CAMs show these storms congealing into a
cold-pool driven MCS this evening as it passes across central
South Dakota towards northeast Nebraska. As the MCS moves into
northeast Nebraska around 05Z (midnight) it should be falling
apart as shear over South Dakota should not be sufficient to
sustain a shear to CAPE balance allowing the outflow to outrun
the MCS. This should mean the MCS enters our area sub-severe,
but we could still see gusts around 35-45 mph initially before
it continues to weaken and fall apart before it reaches Omaha.
We could see a few remnant showers along and north of I-80
Thursday morning before the shortwave exits to the east bringing
an end to rain chances by the afternoon.

Going into the end of the week, we see the ridge over the
Rockies shift eastward increasing heights and shutting down
rain chances going into the weekend. This will cause a warming
trend with the hottest days being Friday and Saturday with heat
indices around 100-105 on Friday and 100-110 on Saturday.

The good news is this ridge doesn`t hang around for long with a
trough pushing into the western CONUS shifting it off to the
east early next week. This will transition us back into a
southwesterly flow pattern bringing back storm chances north
starting Saturday night into Sunday, and nightly chances
continuing into next week. This will also lead to a cooling
trend through the first half of next week.

While there isn`t a strong signal for temperature trends going
beyond the 7-day forecast, the CPC is predicting drier
conditions developing in the 8-14-day time range.

.AVIATION /00Z TAFS THROUGH 00Z FRIDAY/...
Issued at 606 PM CDT Wed Aug 13 2025

VFR conditions are expected to prevail through the forecast
period. A possible exception is at KOFK tonight (14/07-09z)
when a complex of thunderstorms could move through that area,
potentially reducing visibilities. Additionally, winds could
become gusty from the northwest when the thunderstorms move
through the area. At KOMA and KLNK, southeast winds at less than
10 kt tonight are expected to strengthen to 15-17 kt with gusts
of 23-25 kt by 14/15-16z.
