.DISCUSSION...
Issued at 1210 PM CDT Sat Jun 28 2025

Summery weather will continue to affect our forecast area through
the week ahead. Initially, a weakness in the broader upper-level
ridge pattern over our region will keep temperatures from becoming
too excessive. Expect highs and lows to be near or even a few
degrees cooler than normal for late June/early July. A building
upper-level ridge over the High Plains by mid week will create a
more northwesterly flow regime over the central and eastern CONUS by
mid to late week, which might even allow a cold frontal boundary to
dip into our area. The pattern will favor continued chances for
mainly afternoon and evening showers and thunderstorms across the
area into next weekend. Where POPs did not quite rise to "Slight
Chance" thresholds each afternoon, adjustments were made to
include at least 15-20% POPs across the area. Widespread severe
weather or flooding rains are not expected, but any slow moving
thunderstorms at this time of year are capable of producing
locally heavy downpours and damaging wind gusts. It`s always
important to monitor changes in the weather with any outdoor
activities to be aware of lightning risks with developing
thunderstorms. /NF/
