Large area of light to moderate rain continues to develop this morning across portions of southern Kansas in association with very strong forcing as 100+ knot upper jet streak dives southeast out of the central Rockies.
Areas of rain with a few embedded thunderstorms will spread across northeast Oklahoma and northwest Arkansas this morning before precipitation begins to shift east of the region this afternoon. Elevated instability will remain marginal, with the best chance for isolated thunderstorms across far eastern Oklahoma and northwest Arkansas.
Cool/dry conditions expected into the day Tuesday before next reinforcing shot of cool air filters into the area Tuesday night into Wednesday. Could see a few scattered rain showers across far southeast Oklahoma and west-central Arkansas Tuesday night into Wednesday morning, but precip amounts will likely remain light.
Temperatures will remain well below normal for the latter part of the work week as another strong upper trough swings through the central/northern plains.
Rain chances return Thursday into Thursday night as stronger isentropic lift develops in right entrance region of upper jet streak.
Currently, precipitation is expected to remain in liquid form before colder air filters into the region by Friday morning, with temperatures falling below freezing across portions of NE OK/NW Arkansas.
Unseasonably cold, but dry, weather is expected to continue through the weekend with the potential for a more widespread freeze Saturday morning.
