.DISCUSSION...
Issued at 1218 PM CDT Tue Jun 9 2026

Subtropical ridging aloft will remained centered over Southeast 
Texas through the end of the week. Low-level flow will remain
onshore, out of the SSE around the west side of the Bermuda high.
Isolated to scattered showers and a couple storms are expected
each day during the late morning and afternoon hours along the sea
breeze, with the relatively highest chances along and north of
I-10. Hot and humid conditions will continue. Probabilities of
reaching the official advisory criteria of 108F remain low, but
there are medium chances of heat indices reaching 105 degrees that
will impact those not acclimated to the heat, especially given
that these are the highest heat indices so far this summer.
Coverage of diurnal convection will begin to increase during the
Sunday/Monday timeframe, as the ridge aloft weakens in response to
a trough amplifying over the Central CONUS. PWATs will increase
above 2 inches due to the combination of a stalling frontal
boundary to our north and a feed of tropical moisture coming in
from the south. This may result in some excessive rainfall
concerns late in the period.
