Issued at 125 PM CDT Fri Jun 5 2026 The welcomed quiet and comfortable weather we have seen comes to an end over the weekend. Continued southerly flow will bring a warming trend across the area through the rest of the forecast period. Unsettled weather arrives late this weekend and into next week as an upper level disturbance lifts out of the southern plains. Can't rule out a few isolated showers or storms on Saturday but believe much of the area will remain dry. Higher chances for showers and storms (50-80%) arrive Sunday into Tuesday associated with the passage of an upper trough and diffuse frontal boundary interacting with a moist airmass. PoPs then trend down and further east into Wednesday with mostly dry conditions expected the rest of the week as ridging develops aloft. Increasingly humid conditions arrive during this time as well given the increased moisture in place. High temperatures in the upper 80s to lower 90s will work with dewpoints in the low to mid 70s to produce heat indices into the upper 90s to low 100s. && .AVIATION /00Z TAFS THROUGH 00Z SUNDAY/...
