Kansas 7-Day Forecast: Highs Jump From 76°F to Mid-80s by Memorial Day

What changed

The National Weather Service forecast for northeast Kansas shows a clear warm-up over the next seven days:

• Friday, May 22: High of 76°F
• Saturday, May 23: High of 76°F
• Sunday, May 24: High of 83°F
• Memorial Day, May 25: High of 86°F
• Tuesday, May 26: High of 86°F
• Wednesday, May 27: High of 81°F
• Thursday, May 28: High of 84°F

That's a jump of about 10 degrees from the weekend's start to Memorial Day, with the warmest days landing Monday and Tuesday.

Why it matters

For corn and soybeans already in the ground, sustained highs in the low-to-mid 80s push growing degree day (GDD) accumulation along at a good clip. Late-May warmth at this level is favorable for early vegetative growth. If your fields still have open rows, the warmer soil temps that come with daytime 80s could affect germination timing — worth keeping an eye on soil moisture alongside the heat.

What to watch next

• Whether the mid-80s hold or push higher into early June. Extended runs above 90°F would be a different story for crop stress.
• Rainfall forecasts alongside this warm stretch. Heat without rain tightens topsoil moisture quickly.
• Updated NWS forecasts later this week — these numbers can shift, especially for Wednesday and Thursday.
