The main concern in the short term will be the sub-freezing temps forecast tonight area wide, ending the 2018 growing season.
Attention then turns to the next weather system Sunday night and Monday.
Cold front has pushed down to the western gulf coast as of early this morning. A cold high pressure center over the Dakotas and Montana, with temps currently in the single digits and teens.
Underneath it, will slide quickly southeast today and be overhead tonight. Low clouds will probably be stubborn to clear, but all indications are that some sunshine will be seen by the end of the
day. Nevertheless, another cool day is on tap.
Clearing skies and light winds beneath the surface high will bring a cold and in some places record breaking, night to the region tonight. Lows will dip into the teens across northeast Oklahoma and northwest Arkansas and into the 20s across southeast Oklahoma.
The broad cyclonic flow over much of the central US will continue into early next week. The next system to traverse this flow will dive down across the west and into the southern high plains by Monday.
Lift from this system will bring some light post-frontal precip, with current forecast thermal profiles supporting a rain/snow mix across portions of northeast Oklahoma and northwest Arkansas. Borderline surface temps and light QPF suggest that this will not be a big deal, with just a dusting expected in spots.
A fairly steady warming trend is expected for the middle to latter part of next week.
