.DISCUSSION...
A strong warming trend begins today and increases more tomorrow.
Afternoon temperatures Saturday may reach the middle 90s in
central Oklahoma and will exceed 100 in southwest Oklahoma and
areas to the southwest. A weak trough will move southeast across
Oklahoma today with resulting northwest winds; however, surface
moisture will increase substantially across southeast Oklahoma
where isolated thunderstorms may form very late this afternoon or
evening before dissipating with sunset. Daytime isolated
thunderstorms may move into western Oklahoma late this afternoon
from a dryline that will range across the Texas panhandle. There
is a small chance that an isolated storm could produce large hail.
On Saturday, conditions will be more favorable for severe
thunderstorms. Only weak waves aloft are forecast to cross the
area, but very strong moisture advection will result in dewpoint
temperatures over 70 east of I-35 with strong instability.
Additionally, a front will move south and intersect with the
dryline which is expected to mix east during the early evening. A
triple point may develop somewhere over western Oklahoma or
northern Texas. Strong shear and instability results in an
enhanced risk for severe storms across southeast Oklahoma with
lower risks to the west which are areas that may be west of the
dryline by the time the cap is broken to allow storms to develop.
This front will push into Texas Sunday with somewhat drier and
milder conditions for the first part of the next week. By
Wednesday humid conditions are again expected with moisture coming
north from the Gulf. A series of weak upper waves keeps
thunderstorm chances in the forecast the second part of the week.
