Still expect IFR to perhaps brief LIFR cigs and fg to impact a few
of the terminals, although timing as been pushed back 1-2 hours
closer to near and just after sunrise Friday. A few showers will
develop close to OUN/OKC around 14Z but for now have not included
TSRA for any of the terminals as convection should remain east.
This will be watched closely. Breezy north winds will accompany a
cold front Through late in the period.
