Surface analysis early this morning shows cold front extending from central Iowa near Des Moines to southeast Nebraska, with wind gusts of 25-35 mph behind the front.
The front is moving along at a good clip and should arrive in Tulsa by late morning/noon. It will be noticeable as winds become gusty. Temperatures will then slowly fall behind the front the rest of the afternoon.
There could be some flurries across portions of northeast Oklahoma, given some mid-level moisture/ascent. Friday will be another bitterly cold morning with lows falling into the 10-15 degree range from Bartlesville to Fayetteville and mid/upper teens elsewhere.
Wind chill values will fall into the single digits with a few locations falling below zero briefly. Winds come back around to the south/southwest on Friday, which will mark the beginning of the weekend warmup.
Temperatures will climb back up into the low to mid-50s for Saturday and Sunday, though it will be a bit cooler across northwest Arkansas.
The next strong cold front will arrive Monday afternoon. Much of the moisture will stay off to the north and east but will continue low precip chances for Monday afternoon across far eastern Oklahoma and western Arkansas.
Rain will change over to snow by Monday night if there is lingering precipitation. The current storm track will keep the heavier precip amounts well north and east, though some light snow accumulations are possible across western Arkansas.
