.DISCUSSION...
Issued at 243 AM CDT Wed Aug 13 2025

Early this morning, a surface ridge of high pressure is building
into the area from the northern Plains. This surface ridge will
remain parked over the forecast are today bringing mostly sunny
skies, light winds as well as more reasonable dewpoints in the mid
to upper 60s. This will lead to some patchy morning fog however,
this will also make the highs in the mid to upper 80s feel less
oppressive. Tonight into tomorrow morning, a upper level shortwave
will move into Nebraska rounding a upper level ridge that is located
over the southwestern CONUS. This feature will attempt to move
towards the area early tomorrow however, dry air in place should
keep it from reaching the CWA. Tomorrow, the aforementioned upper
level ridge over the southwestern CONUS will build eastward. Height
rises will allow temperatures to rise into the mid 80s to near 90.
By Friday and Saturday the upper level ridge axis will be centered
over the forecast area aiding in highs rising into the low to mid
90s. Factoring in dewpoints in the low to mid 70s will yield heat
index values of 100-105 degrees both days. A heat advisory may be
needed.

Sunday/Sunday night a upper level shortwave trough will round the
northern periphery of the upper level ridge across the northern
Plains into the Upper Midwest. While this will not bring
precipitation to the area it will act to flatten the ridge over the
region. However, temperatures are still forecast to achieve the low
to mid 90s on Sunday with heat index values in the 100-105 range.
Monday, an additional upper level shortwave is expected to round the
flattened ridge into the area bringing the next chance for
thunderstorms that will need to be monitored for severe weather
potential. Storms are progged to continue into the middle of next
week as the pattern becomes active. Temperatures by Tuesday will
also return to near normal with highs in the mid 80s to lower
90s.
