.KEY MESSAGES...
Issued at 1210 AM CDT Mon Aug 18 2025

 - Dangerous heat will persist through Tuesday in most areas, with
heat headlines required for many locations each day. Isolated
afternoon convection will be possible again today.

 - Shower and storm chances increase across mainly northeast
Oklahoma and northwest Arkansas Tuesday, then spread south Tuesday
night and Wednesday as a cold front moves across the area. This cold
front will provide some relief from the heat for the middle to
latter part of the week through next weekend.

&&

.SHORT TERM...
(Today)
Issued at 1210 AM CDT Mon Aug 18 2025

Hot and humid conditions will persist today, with afternoon high
temperatures once again climbing into the 98 to 102 degree range.
Heat index values will be similar to those observed Sunday,
generally in the 103 to 110 degree range, and the current heat
advisory will continue as is. Isolated afternoon convection is once
again expected, but overall coverage will likely again be sparse.

&&

.LONG TERM...
(Tonight through Sunday)
Issued at 1210 AM CDT Mon Aug 18 2025

The upper ridge that has been parked over our area for the past
several days will shift west Tuesday and Wednesday allowing a cold
front to drop south across the area. The latest data is trending
faster with the southward progression of this front, suggesting that
at least northern parts of the forecast area may see some relief
from the heat on Tuesday. Have lowered NBM temperatures slightly as
a result. Shower and storm chances will increase Tuesday, especially
across the north, with the higher chances spreading south Tuesday
night and Wednesday. Rain chances may continue in the south Thursday
as well, but the better chances will likely be shifting off to our
south by then. Lowered NBM temperatures slightly Wednesday and
Thursday as well given the trends in the model data.

A secondary push of cooler air may arrive next weekend as well
helping to keep temperatures below the seasonal averages for an
extended period of time.
