The cooler weather will persist through the week, with temperatures much closer to the seasonal averages, although most locations will still be slightly above normal overall for the week.

IFR/MVFR ceilings across northeast Oklahoma and far northwest Arkansas are forecast to continue through much of the morning hours.

Also during the day, mainly over southeast Oklahoma and northwest Arkansas, low rain/storm chances remain before the elevated frontal boundary exits. With limited potential storm coverage will hold off on mentioning in the TAFs. Scattered high clouds continue into tonight, while at the same time potential for IFR and or MVFR ceilings develop for parts of northeast Oklahoma and far northwest Arkansas. Will add a tempo group for timing at the far northwest Arkansas terminals. Winds through the period start out variable and become northerly through the morning hours.
