Another thunderstorm complex is expected to develop to the west
this evening and move eastward into portions of eastern Oklahoma
and western Arkansas after midnight. Damaging winds from 60 to 70
mph will be the primary severe weather threat with this line of
storms, although locally heavy rainfall is likely as well. Isolated
flash flooding could become a concern in areas that saw a lot of
rainfall earlier this morning.
During the afternoon hours, isolated to scattered thunderstorms
may develop across areas north of Interstate 40, posing a limited
severe weather threat prior to the larger threat tonight.
Chances for thunderstorms will largely remain across northeast
Oklahoma and northwest Arkansas during the early part of this week
as an upper level system moves across the Northern Plains. Upper
level ridging will begin to build across the Southern Plains and
will become the dominant weather feature from mid week on.
