.DISCUSSION...
Issued at 149 AM CDT Tue Jul 28 2026

Quieter and much drier weather arrives today as winds pick up
from the north. Gusts up to 20 to 25 mph at times will help usher
in a dry and sunny day as high pressure moves into the region.
Temperatures are expected to remain near or above normal today
before warm air advection again increases through the middle of
the week. High temperatures on Thursday could get back towards the
middle to upper 80s and maybe even low 90s, which could produce a
few sporadic showers in the afternoon. Still, no widespread
active weather is expected until sometime Thursday night into
Friday with the next frontal passage. Rain and storms then stick
around Friday into early Saturday before some quieter conditions
return for the latter half of the weekend.
