.DISCUSSION...
A persisting upper high across the southwestern U.S will continue
to bring northwest flow across the southern plains, rolling in
another round of showers and thunderstorms off the central high
plains. Latest HRRR and Texas Tech WRF models suggest a few storms
begin moving into far northwest Oklahoma around 10 pm, and not
advancing very far before dissipating by early Thursday morning.
So far, the risk for these storms is marginal, with up to golfball
size hail and strong to severe wind gusts possible.

The remainder of Thursday is expected to be dry with seasonably
normal temperatures, with chances for more widespread TSRA
returning on Friday through the weekend as a series of short wave
disturbances in the upper flow come through. For Friday into
Friday night, the storm and rain chances increase as an advancing
surface boundary will interact with an upper wave. For this
weekend, both GFS and ECMWF suggest additional storms possible as
a few more short waves pass through, but uncertain with the timing
or moisture available, so POPs will remain low until we get
closer in time. One thing for sure, unseasonably cooler air
lagging behind Friday`s cold front passage should be arriving by
Saturday night. Temperatures for Sunday are expected to 10 to 15
degrees cooler than normal for early Summer.
