.DISCUSSION...
Issued at 135 PM CDT Mon Jun 22 2026

Upper ridging will continue to build into the region today, with
high pressure at the surface. Despite some cloud cover, the height
rises have allowed temps to warm into the lower 90s across most
of the area. Fortunately, with the drier air working its way in
with the ridge, dewpoints have fallen into the mid 70s. This has
tempered the heat indices from rising above 107, however some heat
concerns will persist.

Dry conditions will prevail through the remainder of the period
as the ridge settles in across the area. Several disturbances to
our north will spark convection over the Mid West and Central
Plains, but the building ridge will provide enough subsidence over
the area to keep a dry forecast. The only concern remains the
potential for heat related issues, as daytime highs climb into
the mid 90s each afternoon and overnight lows fall into the mid
to upper 70s. The lower dewpoints will also persist, so we will
likely remain below heat advisory criteria. Those most vulnerable
may still be susceptible to the heat, so heat safety actions
should be in place each day.
