 - Another morning with much needed rain across parts of the area.
   A few strong storms possible, along with heavy rainfall and

.SHORT TERM...
(Today and tonight)
Issued at 119 AM CDT Sun Aug 11 2024

Area of showers and thunderstorms will continue to move east across
central into eastern Oklahoma this morning. No severe weather is
expected with this activity, however very high precipitable water
will result in efficient rain producers and heavy rainfall with
some isolated flooding possible.

This will also keep temperatures bit cooler along and east of I-35
compared to normal, although not as cool as was seen Saturday.
Farther west where more insolation is expected along with increasing
southerly low level flow and warming boundary layer temperatures
will respond and climb back into the upper 90s and lower 100s. These
temps combined with dewpoints in the 60s will result in afternoon
heat indices between 105 and 110. Will likely go with a Heat
Advisory for portions of southwest Oklahoma and western north Texas.

For tonight, there remains a chance for a few showers/storms across
northern Oklahoma with better chances shifting north and northeast
of the area. South winds will remain breezy which will aid in
keeping overnight temperates quite a bit warmer than we have had
the last few nights.

&&

.LONG TERM...
(Monday through Saturday)
Issued at 119 AM CDT Sun Aug 11 2024

Although upper ridge begins to build back north still appears there
will be a low chance for a few showers along the Oklahoma Kansas
border Monday night. Otherwise, the middle of the week will be much
warmer with little in the way of rain chances. Will also see a
stretch beginning Monday and possible lingering through much of the
week for daily need of heat headlines as hot and humid conditions
remain in place.

Models then diverge as we go toward the end of the work week wrt to
strength or lack of upper ridge and possible trough/front and some
additional rain chances. For now will keep some low pops and
slightly cooler(less hot) temperatures, especially across the
north.

.AVIATION...
(18Z TAFS)
Issued at 1226 PM CDT Sun Aug 11 2024

Current stratus deck across the eastern half of Oklahoma will
maintain MVFR conditions through 06Z affecting terminals KOKC,
KOUN, KSWO, KPNC, and at least through 21Z at KDUA. All our
remaining terminals should remain under VFR conditions. A lifting
warm front will be veering surface winds out of the south-
southeast up to 15kts. A strong low-level jet developing after 06Z
will result in low-level wind shear across most of our terminals.
TSRA may develop after 03Z across central Oklahoma although
highest probabilities are 30% across northcentral Oklahoma
affecting terminals KSWO and KPNC.
