The main forecast concern this period will be the return of the heat and above normal temperatures to the area through the weekend into next week. This heat will come courtesy of a upper level ridge that currently resides over the Four Corners region. This feature will begin to slide eastward and build over the the western Plains today. This will provide local height rises allowing highs to warm a few degrees despite surface high pressure in place. Expect highs in the mid 80 to near 90. By Saturday, the local area comes further under the purview of the ridge as the axis moves into the central Plains. In addition, strong WAA will get underway at the surface. This will allow highs to rise into the upper 80s to mid 90s. Sunday, the ridge axis moves directly over the local area. This coupled with continued strong WAA will drive highs into the mid to upper 90s.

The local area then remains under the influence of the upper level ridge through the duration of next week as it remains in control from the southeastern CONUS back into the central and southern Plains. This will keep highs in the mid to upper 90s. While temperatures will be 10-15 degrees above normal, dewpoints in the low to mid 60s through Tuesday will keep heat index values Sunday through Tuesday in the 95-102 degree range. By Wednesday and Thursday, dewpoints begin to rise a bit into the upper 60s to near 70, yielding some heat index values approaching 105. It is this period that may need to be monitored for heat products.

Otherwise, conditions look to remain mostly dry the next week. The one exception will be for areas of northern Missouri where slight chance (15-25%) PoPs will be possible nightly from Sunday night through Wednesday night. This will come as models suggest periodic, weak upper level disturbances will try to push into the upper ridge. The recent model runs have trended drier so confidence is low in precipitation chances.

High clouds from a thunderstorm complex passing through west central KS linger through the overnight. This may slow cooling limiting BR/FG impacts anticipated earlier. There will likely be some intermittent VIS impacts over the next several hours, but any BR/FG is more likely near the MO River. Any VIS impacts clear up after sunrise. Winds are light and variable overnight becoming more SE through the day with diurnal CU anticipated.
