DISCUSSION

Issued at 1256 PM CDT Sat Aug 1 2026

A very pleasant Summer day is underway as much of the area currently sits in the upper 70s and low 80s with minimal humidity. This has been made possible by yesterday's frontal boundary and the large upper low that is slowly making its way southeast across the upper Mississippi River valley. Expect fairly breezy northerly winds for the remainder of the afternoon today with mostly clear skies and highs in the low to mid 80s. By this evening and into the overnight hours, surface ridging builds in from the north helping to calm winds a bit. With mostly clear skies, efficient radiative cooling should take place with some patchy ground fog becoming possible around sunrise Sunday morning. Low-level moisture seems to be fairly shallow, so not expecting widespread dense fog, mainly just fog in low-lying areas and river valleys. Expect another nice summer day Sunday with temperatures topping out in the mid to upper 80s. Humidity should again be pleasant by the afternoon as Tds remain in the low to mid 60s.

Temperatures are expected to slowly climb through the week as mid- level heights increase beginning Monday. High temperatures Monday through Thursday will be around average for this time of year - topping out in the upper 80s and low 90s. As for rain/storm chances, Monday and Tuesday should remain mostly dry as better chances remain well north of the area. By Tuesday night and Wednesday, mid-level troughing ejecting off the northern Rockies will help push an inverted trough across Kansas and help to increase precipitation chances. A brief lull in precipitation chances may come Thursday before additional mid-level waves return chances by Friday. Cannot rule out some stronger storms in this timeframe given the available energy and shear, but at this time, confidence in widespread strong/severe weather remains low.

Rain chances will not be zero heading into the weekend, but as mid- level ridging builds back east into the central Plains, heat and humid conditions will become the main headline again. Given the 10% chance or so of PoPs by the weekend, confidence in heat indicies getting above 105 degrees is low at this time, but NBM probabilities currently sit in the 20-40% range for HI above 100 degrees by Friday through Sunday. Extended guidance beyond the weekend seems to keep zonal/northwesterly flow across the central and northern Plains so not expecting another long-term heatwave at this time.

North winds weaken over the next few hours, staying light through the remainder of the period. Skies stay clear as well. With the light winds and clear skies, could see some brief/patchy fog towards sunrise, most likely in favored low-lying spots such as KTOP.
