DISCUSSION

Issued at 1024 PM CDT Mon Jul 6 2026

Tonight and Tomorrow...

Quiet conditions will prevail this evening as the area remains on the northeastern periphery of a mid-level ridge centered over the Four Corners region. At the surface, a broad corridor of high pressure extends from eastern Nebraska into the Upper Midwest. Light winds and humid conditions will support the potential for patchy fog overnight. However, gustier winds just above the surface should keep fog mainly confined to low-lying and wind-protected area.

On Tuesday, mid-level ridging will continue to overspread the region, bringing afternoon highs in the upper 80s to low 90s. Later Tuesday, a shortwave disturbance moving across the northern Plains will help dampen the ridge across the area, transitioning the pattern toward more zonal flow aloft. This disturbance will also push a quasi-stationary frontal boundary into the northern Plains, with strong to severe storms expected to develop along it across the Dakotas. A few strong to severe storms may persist far enough south to move into far northeast Nebraska late Tuesday night into early Wednesday. Damaging wind gusts (up to 60 mph) and hail (up to 1 inch) would be the primary hazards, though both instability and deep- layer shear are expected to decreased with southward extent into the forecast area.

Wednesday through Friday...

Wednesday through the remainder of the work week will feature generally zonal flow aloft, with a series of shortwave disturbances passing through the region. These waves will gradually push the aforementioned quasi-stationary front southward over several days while bringing periodic chances for showers and thunderstorms along and near the boundary.

Wednesday will be another warm and humid day, with afternoon highs in the upper 80s to low 90s. Increasing low-level moisture transport will push dew points into the low to mid 70s, resulting in heat index values in the mid to upper 90s. Thunderstorm chances return Wednesday, though the potential for afternoon/early evening development appears rather isolated. Better chances arrive late Wednesday night into early Thursday as stronger mid-level flow overspreads the region and helps initiate storms along the frontal boundary, likely positioned somewhere near east-central Nebraska into west-central Iowa. Shear and instability do not appear overly impressive, but should be sufficient for scattered strong to severe storms.

Temperatures will be a bit cooler on Thursday behind the front, with lingering cloud cover and slightly cooler airmass keeping highs in the mid to upper 80s. Additional convective redevelopment is expected late Thursday into Friday along the front, which by them will likely be located closer to southeast Nebraska and southwest Iowa as it continues its slow southward push. Once again, ingredients remain sufficient, though not particularly robust, to support a strong to severe storm or two. Friday highs will remain on the milder side, generally in the mid to upper 80s, with lingering showers and cloud cover possible along and behind the front.

Saturday and Beyond...

This weekend into early next week, an amplifying mid- to upper-level ridge is expected to build over the Front Range and gradually expand eastward into the mid-Missouri Valley, leading to a warming trend. Highs on Saturday will take a step upward into the upper 80s to mid 90s. By Sunday and Monday, most locations are expected to reach the 90s, with heat index values approaching or exceeding 100 degrees in some areas. A generally hot and humid pattern is expected to continue into next week.

Issued at 1150 PM CDT Mon Jul 6 2026

VFR conditions are forecast with mostly clear skies and light southerly winds expected to persist through the period. There is a slight chance of fog development overnight, but expect the chance of it impacting any given TAF site is only about 10-15%, so it was not included in the forecast.
