...New SHORT TERM, LONG TERM, UPPER AIR...

.SHORT TERM...
(Today and tonight)
Issued at 259 AM CDT Tue Jul 27 2021

A few showers and thunderstorms have developed across eastern OK
early this morning, likely associated with an MCV. This feature
will move southward throughout the day to near the I-35 corridor
by mid day and then across the Red River around this evening.
Expect the highest PoP coverage throughout the day near these
areas. Out west, a few diurnally driven showers and storms could
develop along an outflow boundary over western/NW OK. Otherwise,
for this afternoon, slightly lower dewpoints should keep us just
below heat advisory criteria for most locations along and east of
I-35 so opted not to issue one for the time being.

.LONG TERM...
(Wednesday through Monday)
Issued at 259 AM CDT Tue Jul 27 2021

Precipitation chances should come to an end Wednesday as the upper
ridge dominates the central CONUS. OK will end up within easterly
flow aloft on its southern side. Temperatures will continue to
climb late into the week and into the weekend, with triple digit
heat index values covering the entire area by Saturday. Downslope
flow ahead of an approaching cold front will result in very warm
conditions Saturday afternoon and OKC may experience their first
100 F degree day. Rain chances will increase Sunday through early
next week along a cold front.
