The upper low was located over southeast Colorado, Oklahoma and Texas panhandles and northeast New Mexico early this morning.
East of the low, areas of drizzle with lower visibilities moving off to the northeast within the mid-level flow were common across much eastern Oklahoma and northwest Arkansas.
Temperatures early this morning have remained above freezing for much of the CWA, with exception to locations west of Highway 75 in northeast Oklahoma and some locations within the higher terrain of far northwest Arkansas.
Thus, we will continue the winter weather advisory for these locations and cancel the advisory for the rest of northeast Oklahoma where temperatures were above freezing. With the freezing temperatures, light freezing drizzle will remain possible with the potential of a light glazing of ice.
Advisory remains till noon and will monitor conditions for any additional updates.
The upper wave is expected to continue to lift northeast through the plains today. The drier air being transported within the west to southwesterly low/mid level flow should help to taper off any remaining drizzle and lower visibilities during the morning hours.
As the upper trof axis is forecast to shift northeast of the CWA by this afternoon. Behind this axis, some possible scattering of clouds will be possible this afternoon/evening for parts of the CWA. Afternoon temperatures look to range from around 40 degrees where the snow fell in western Osage County to the lower 50s near the Red River.
Temperatures look to continue a warming trend peaking saturday with gusty southerly winds ahead of the next forecast cold front.
A second wave is progged to drop southeast into the desert southwest in the wake of the departing wave tonight and Thursday and lift into the southern/central plains Friday and Saturday.
This will allow for a return of rain showers beginning Thursday night, with showers and thunderstorms continuing Friday and increasing Saturday morning as a cold front looks to move through the region.
