.SHORT TERM...
(Late Afternoon into Tonight)
Issued at 209 PM CDT Mon Jun 24 2024

Have upgraded portions of northeast Oklahoma to an excessive
heat warning from the heat advisory through 9 pm this evening.
Heat index values of 110 to 112 will be possible within this
area.

Another toasty night is on tap for eastern Oklahoma and
western Arkansas with temperatures bottoming out in the
mid 70s to lower 80s area-wide.

.LONG TERM...
(Tuesday through Monday)
Issued at 209 PM CDT Mon Jun 24 2024

Have expanded the heat advisory to include the entire CWA on
Tuesday with heat index values expected to be in the 105 to 110
degree range during the afternoon.

The chances of showers/storms ramp up Tuesday night into
Wednesday as the upper level ridge retrogrades enough to the
west to allow a brief window of northwesterly flow aloft. A mid
level shortwave embedded within the northwesterly flow aloft will
aid in thunderstorm development during this time as will an associated
weak surface boundary. A few of these storms could be strong to
severe with damaging winds and large hail the concern.

Above normal temperatures are expected to continue through the
forecast period as the upper level ridge builds back over the
area. Low chances of showers/storms are still possible across
northern portions of the area over the weekend as a weak frontal
boundary attempts to push in from the north.
