KEY MESSAGES

- Highs in the 90s today will increase to the upper 90s to low 100s for Monday (to as high as 103 degrees). Around 50-70% of the area will be expected to reach the triple digits.

- A Heat Advisory will be in effect from 10AM to 10PM Monday as Heat Index values may climb to as high as 105-110 degrees.

- A cold front passing through early Tuesday will pull highs back down to the 80s to low 90s for the period Wednesday through Friday.

- Though a few storms may come in from the west overnight Tuesday (10-30% chances), the next widespread precipitation chances come mainly on Wednesday (40-70% chances) and Thursday (30-50% chances).

UPDATE

Issued at 200 AM CDT Sun Jul 19 2026

Synopsis...

An upper level ridge (higher pressure) continues to remain centered over the intermountain west region with troughing (lower pressure) building across the eastern U.S. Here in the center of the U.S. (more so influenced from the higher pressure center just west of the area), conditions continue to remain fairly dry with steadily increasing temperatures through Monday.

Today...

Highs this afternoon will spread the 90s with heat index values in the upper 90s to low 100s. Winds today out of the southeast will mainly blow between 5 to 15 MPH with occasional gusts as high as 20 MPH. Skies will continue to remain mostly clear with no chance for precipitation.

Monday...

Though a few non-sever storms overnight Sunday could reach into portions of north central Nebraska, it is unlikely that remnant showers from these storms will impact more than just a handful of locations north of I-80 during the early morning hours on Monday (<20% chances). Though the main concern for Monday will be the heat, there is still a small concern if any cloud coverage from these potential morning showers linger into the afternoon, possibly impacting highs in a few far northern areas. Temperatures for most of the area, however, will still be likely to reach into the upper 90s to low 100s (to as high as 103 degrees). Around 50-70% of the area will be expected to reach the triple digits. Given dewpoints in the mid 60s to low 70s, heat index values across the area should easily reach up into the 100s with values expected to climb to as high as 105 to 110 degrees. As result of this heat, a heat advisory will be in effect from 10AM until 10PM on Monday for the full area.

All of central and south central Nebraska as well as a few far northern portions of north central Kansas will be under a Major heat risk classification (level 3 of 4) for monday. This level of heat suggest that heat related illnesses could be possible for anyone without the proper use of hydration or an effective source for cooling. In addition, due to the combination of light southerly winds and mostly clear skies, Wet Bulb Globe Temperature values (WBGT) are forecast to reach Extreme levels (level 4 of 4) as natural colling sources should be limited (heat relief from wind or clouds).

Tuesday...

A cold front expected to pass overnight Monday into Tuesday morning will bring some heat relief to the area, though highs will still probably remain in the 90s for at least Tuesday. Though much of the day will be expected to remain dry, a handful of storms could still blow in from the west during the evening to overnight hours (10-30% chance across mainly north and western portions of the area). Otherwise, winds flipping to the north/northeast behind the front, may gust as high as 20-25 MPH across the afternoon hours.

DISCUSSION

Issued at 240 PM CDT Sat Jul 18 2026

This afternoon-Tonight...

Temperatures this afternoon are currently in the 90s with heat index values expected to top out around 100 degrees. Two main areas of isolated-scattered shower/thunderstorm development are possible this afternoon-evening, though an isolated storm can't be ruled out across most of the area. The first is mainly along and north of Highway 92 in Nebraska, with a second area possible for areas along and south of a Stockton-Hebron line. Whatever showers/storms do form look to be fairly brief and weak given poor shear. These summertime pop up storms should wane around sunset as stability increases. Lows tonight will be in the upper 60s to low 70s with light winds.

Sunday...

Ridging aloft over the eastern Rockies/western Plains continues on Sunday. At the surface another hot and humid day is expected across the area as temperatures climb into the 90s. Similar to today/Saturday, heat index values reach the upper 90s to around 100 degrees during the afternoon/early evening. Will need to keep an eye on the potential for a few scattered, non-severe storms to move into far northern portions of the area Sunday night, though confidence is too low to include in the forecast at this time.

Monday...

Monday remain on track to be the hottest day of the forecast period as highs soar into the upper 90s to low 100s. It's possible that temperatures could be a few degrees too warm if dewpoints are slow to mix out. Regardless of the exact high, dewpoints combined with hot temperatures will result in heat index values in the 100s on Monday. A Heat advisory will likely be needed for at least a portion of the forecast area given the support for fairly widespread low-mid 100s heat index values. A cold front pushes into the area late Monday evening-night. An isolated storm is possible along this front as it moves into northern portions of the forecast area, but any storm will likely be on the downtrend as it enters the forecast area given the time of arrival.

Tuesday Onwards...

Aloft a trough diving into the Midwest begins to transition the upper level flow into a northwesterly flow regime on Tuesday. While slightly cooler than on Monday, temperatures on Tuesday remain hot as they climb into the 90s (warmest KS). Temperatures sink towards their climatological normals Wednesday onwards with highs in the 80s to low 90s. More widespread precipitation chances (20-50%) arrive on Wednesday and continue through the end of the forecast period. Details on these chances will become clearer as we get closer in time.
