.SHORT TERM...
(Today and tonight)
Issued at 154 AM CDT Tue Jul 19 2022

Today is expected to be the very hottest day of the week across all
of western and central Oklahoma and adjacent northern Texas. The
Excessive Heat Warning remains in effect for all of these areas this
afternoon. Both temperature and apparent temperature are expected to
reach around 112 over nearly all of the area. A surface low pressure
area is expected to deepen over southwestern Kansas into the
panhandles. This will increase southwesterly winds and bring drier
air into western and central Oklahoma. Conditions are such that a
Red Flag Fire Warning has also been issued for west central and
southwestern Oklahoma this afternoon and evening. The surface trough
is expected to move into northwestern Oklahoma tonight.
Additionally, the southern extent of a shortwave trough passing
through the central and northern plains will pass through Oklahoma
tonight. This may be enough for some isolated showers and
thunderstorms as indicated by weak signals in various models.

.LONG TERM...
(Wednesday through Monday)
Issued at 157 AM CDT Tue Jul 19 2022

Heat will continue to be the major story into the long term, though
not without a few complications.

On Wednesday, a cold front will enter northwest Oklahoma and stall.
This will give us cooler temperatures in northwestern parts of
Oklahoma (and by cooler I mean 101 to 105 degrees), while southern
Oklahoma and north Texas will continue to experience the scorching
southwest winds keeping highs in the 106 to 110 degree range. Will
convert the Excessive Heat Watch to a Warning and add a few counties
+ a Heat Advisory to surround the warning. May need to extend the
advisory farther on future shifts, but with uncertainties
surrounding the front, will stay conservative at this time.

The upper level ridge will start shifting westward toward Arizona,
while an upper trough passes through the Great Lakes region. With
this shift, 850mb temperatures will cool into the mid 20s C. This
will allow for slightly cooler surface temperatures Thursday and
Friday (in the 99 to 104 degree range). Heat advisories may again be
needed, but areal coverage should be significantly less.

Additionally, between lingering boundaries (e.g. the above mentioned
cold front), daytime heating, and the westward shift in the upper
high, a few widely scattered showers and storms are not out of the
question for the Wednesday through Friday period. For Wednesday
afternoon and evening, adding some mentionable 10% PoPs in south
central Oklahoma where an isolated strong to severe wind gust could
occur. Outside of that, however, will leave most of the
probabilities unmentionable as any impacts should be minimal and
probabilities are low.

Toward this weekend, the ridge shifts back eastward, suppressing
precipitation chances and allowing temperatures to increase a few
degrees. In contrast to the steady predictable pattern we've been in
for weeks on end, synoptic models start to diverge early next week.
