.DISCUSSION...
Issued at 306 AM CDT Sun Jun 14 2026

Upper flow was nearly zonal early today but several waves rotating
around an upper low over over eastern Canada will allow moderate
northwest flow to dominate through the bulk of this forecast. Cold
front with one wave was south of Kansas as of 07Z with north to
northwest winds providing moderate cold-air advection for a much
cooler and drier day today and Monday. A weak cold front passes
through late Monday night into early Tuesday. Limited low-level
moisture return should keep frontal precipitation in check but some
isentropic lift could support some showers and storms Monday night
and again Tuesday night ahead of a stronger upper wave moving across
the upper Mississippi Valley. This wave brings a stronger front
through late Wednesday into Wednesday night. Breezy pre-frontal
south to southwest winds make for a much warmer Wednesday with some
heat indices likely reaching triple digits. Veered winds off the
surface should keep the better moisture to the east but there is at
least some chance for thunderstorms late Wednesday into early
Thursday. There may be enough shear and instability for some severe
weather potential, with LREF probabilities of at least 2000 J/kg of
surface CAPE around 50% for eastern areas, but details on CAPE and
CIN are far from certain at this range. Temperatures back off a bit
Thursday and Friday, but upper flow becoming more zonal brings
warmer temperatures and perhaps some precipitation Saturday.

Issued at 1209 PM CDT Sun Jun 14 2026

North winds around 10 kts with some minor gusts continue into the
evening, then quickly weaken after sunset. Can`t rule out some patchy
shallow fog in the river valley around TOP towards sunrise, but
otherwise VFR conditions will prevail.
