549 AM CDT Sun Jul 25 2021
...New AVIATION, UPPER AIR...
.SHORT TERM...
(Today and tonight)
Issued at 227 AM CDT Sun Jul 25 2021
Weak warm advection will allow for some isolated showers and a
thunderstorm or two this morning over northern OK. A Heat Advisory
is in effect today through 7pm for areas along and east of I-35
as heat indices will hover around 105-107 this afternoon. Mid-
level ridging, along with warm 850 mb temperatures and low 70s
dewpoints will aid in hot and muggy conditions across the state.
Later this afternoon, a convective complex is expected to move
through Kansas, and an associated weak boundary should push off
into parts of northern OK. In doing so, weak convergence along
this boundary should allow for some storms to initiate along it,
as a moist boundary layer is already in place. These storms are
not expected to reach much further than central OK, as steering
flow is weak.

.LONG TERM...
(Monday through Saturday)
Issued at 227 AM CDT Sun Jul 25 2021
The aforementioned convection along northern OK will linger
through Monday morning and into the early parts of the afternoon.
Model guidance differs on the evolution of precipitation, so will
keep low probabilities across northern OK through Monday
afternoon.
Mid-level ridging will become dominate the Central and Southern
Plains through the long term. Heat advisory criteria could be met
each day in the long term, but confidence at the moment in any
particular area is low at this time. Any precipitation over the
area seems to be unlikely through the remainder of the week.

.AVIATION...
(12Z TAFS)
Issued at 544 AM CDT Sun Jul 25 2021
A few showers and thunderstorms are expected this morning, with
additional chances this afternoon. Most of the precipitation
should remain over northern and western OK before 00Z. However,
have not included any mention of precip in the terminals for this
morning. Winds will generally remain south to southeast. Scattered
cumulus and cirrus are expected by this afternoon.
