DISCUSSION

Issued at 152 PM CDT Sat Jun 27 2026

A deep upper low persists over the northwestern CONUS with the base of the trough extending into the Central Great Basin. An upper ridge axis extends down from the Northern Plains through the Mississippi Valley. At the surface, lee troughing has strengthened across the high Plains, increasing the pressure gradient across the Plains and resulting in breezy southerly winds in our area. Heat index values between 100-105 are possible late this afternoon into the early evening hours across much of the area as high temperatures rise into the upper 80s to lower 90s with dewpoints in the 70s. As we move into tonight, low temperatures will stay about 10 to 15 degrees above normal for this time of year with lows in the upper 70s.

This pattern will continue through much of this forecast period. Upper ridging over the eastern CONUS will persist, keeping southwesterly flow aloft over our area. The upper low will shift into the Northern Plains by Monday afternoon as an upper trough shifts into the southwestern US. Thickness will increase as heights rise supporting warmer temperatures with highs in the 90s through Friday. The increased pressure gradient will remain likely through Saturday, keeping breezy southerly winds with dewpoints in the 60s and 70s over the area. Given these conditions, heat indices up to 105 are likely on Sunday and Monday afternoons into the early evening hours. For Tuesday and Wednesday, heat indices will likely be lower between the upper 90s to around 100 before they increase again on Thursday with the warmest indices in southern Kansas. A Heat Advisory remains in effect for Sunday through Thursday. Mostly dry conditions are forecast through the work week. There is a slight chance for rain to clip central KS on Tuesday night as an upper shortwave moves into the Central Rockies, though better chances will stay north in Nebraska. Outside of this slight chance, dry conditions will prevail as upper ridging continues to influence the region.
