LINCOLN, Neb. (KOLN) - The forecast remains largely unchanged as we head into the middle and end of this week as a dome of high pressure will lead to mainly dry weather with a rather brutal stretch of heat and humidity expected to impact the area by the end of this week.

We could see a few more clouds throughout the day Wednesday but for the most part it should be a very similar day to where we’ve been the past few days. Some patchy fog will be possible again in the morning, but again, more dry weather is forecast for the day on Wednesday.

Look for mostly to partly sunny skies by the afternoon with temperatures likely reaching the upper 80s to upper 90s across the state.

The extended forecast continues to advertise a rather brutal stretch of heat and humidity later this week which could lead through the weekend and into early next week as temperatures are forecast to surge into the mid and upper 90s under the dome of high pressure. Dew points will likely also be reaching back to the upper 60s and the lower and middle 70s and when combined, we will likely see heat index values between 100° and 107° at times later this week, this weekend, and potentially at times early next week. Mainly dry weather is forecast for the next several days, but a disturbance will try and pass through the area late this weekend and perhaps into early next week that could offer us some scattered rainfall across the state. Towards the end of the extended forecast period, models are hinting at the potential for some triple digit heat across much of the state, and if it we stay mainly dry for the next week, it will certainly be possible with this strong ridge of high pressure in place.
