Discussion...
area of showers and storms in northwest OK early this morning will continue
to move east across portions of northern and central Oklahoma. Low
chance for showers/storms will continue across portions of northern
OK this afternoon/tonight.

Rain chances will increase Wednesday into Thursday as an impulse in
the southern stream affects the Southern Plains with moisture
advection occurring ahead of this disturbance. The highest chances
will be in SW/S parts of the fa. Enough instability and shear could
develop Thursday for a few strong to marginally severe storms to
occur across southern portions of the area. The shear does not look
overly strong so these storms will likely be more multi-cell, pulse
storms than large supercells.

Models show a shortwave moving across the southwest U.S. Into the
southern/Central Plains late this week into the weekend which will
continue the chances for showers and thunderstorms. Models differ
how quickly this shortwave exits the region, but both tend to agree
that after it does northwest flow aloft will develop, at least for a brief
period of time, next week. This would lead to the possibility of
more nocturnal activity late this weekend into early next week with
showers/storms developing in High Plains and possibly moving into
the area.
