.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.

(12Z TAF Issuance)
Issued at 605 AM CDT Mon Jun 22 2026

MVFR CIGS will scatter and lift out later this morning. VFR
conditions prevail through the daytime with breezy S/SE winds
with gusts around 20 knots, up to around 25 knots along the
coastline. Winds and gusts diminish this evening with another
round of MVFR CIGS filling in overnight. Cannot rule out a short
period of IFR CIGS early Tuesday morning, with chances for IFR
conditions more favorable N/NW of the Houston Metro area. CIGs
scatter out again after sunrise.
