.SHORT TERM...
(Today and tonight)
Issued at 417 AM CDT Tue Aug 22 2023

An Excessive Heat Warning and Heat Advisory are in effect today
from 11 AM to 9 PM for much of the area. We opted to move the
start time of these headlines forward an hour as locations with
higher dewpoint temperatures (namely Kay, Noble and Payne Counties)
will lead to excessive heat warning criteria by late morning. Although
air temperatures and heat index values are expected to be a few
degrees lower than yesterday, the overall impact is the same if
not compounded as the consecutive number of 100+ deg days continues
to grow (3 to 5 days for north, central, south OK; 6 days for
southwest OK and north TX).

.LONG TERM...
(Wednesday through Monday)
Issued at 417 AM CDT Tue Aug 22 2023

An Excessive Heat Warning has been issued for Wednesday along our
eastern-most row of counties and some of our southern two tiers
that border Texas. A Heat Advisory has also been issued and
includes Enid, OKC, Chickasha, Lawton, and Wichita Falls.

Triple digit temperatures continue through Saturday as the broad
center of the upper ridge retrogrades slowly across the south-
central plains. Models show an uptick in H850 temperatures on
Thursday as the center of the ridge moves directly overhead and as
surface winds veer to the southwest. While there will be an ever
so slight dip in maxT on Wednesday, highs are forecast to tick
upwards again on Thursday and Friday as low-level flow veers
west-southwest. The drier advecting with the downslope flow will
contribute to elevated fire weather risk across southwest Oklahoma
and western north Texas on Friday, and again on Saturday.

The center of the 500mb high is prog'd to reach the four corners
region on Sunday or Monday. By this time, the upper level pattern
becomes highly amplified with a trough becoming more elongated
over eastern Canada and the US. A front still appears to sag into
Oklahoma late Saturday and into Sunday. North of the front, forecast
highs (north/central Oklahoma) drop into the 90s with 100s still
expected across southern OK and western north TX on Sunday. Greater
relief is anticipated on Monday for the entire CWA with highs ranging
from the upper 80s to the 90s. This appears to continue into at least
middle of next week. Storm chances remain in the forecast beginning
late Saturday, though POPs remain low.
