.DISCUSSION...
Issued at 1047 PM CDT Sat Jul 25 2026

Heat will be the primary concern through the period as an upper-
level ridge across the Central US looks to remain in place through
the week. Rain free conditions are forecast to continue through
the work week with sunny to mostly sunny skies prevailing across
the area.

There is a Moderate Heat Risk (level 2 of 4) across the area
Sunday afternoon as high temperatures are forecast to reach the
upper 90s to low 100s. Heat index values are forecast to peak
around 105-110 across the area, and Heat Advisories likely wont
be needed.

High temperatures are forecast to gradually increase through the
week, with widespread 100-105 degree temperatures forecast by
Monday climbing to the 102-110 range by Friday. Moderate (level 2
of 4) to Major (level 3 of 4) Heat Risk is expected across the
area through the week, with portions of the Rio Grande Valley
possibly reaching Extreme Heat Risk (level 4 of 4) late in the
week. Heat index values are forecast to range between 110 and 115
through the work week, with a few locations possibly hitting 117
late in the week. Heat Advisories will likely be needed daily
Monday- Friday, and a few Extreme Heat Warnings may be needed
towards the end of the week.
