Rain is expected to continue to affect eastern Oklahoma and western Arkansas through this morning as a mid-level shortwave currently over southwest Texas moves across the area.
Temperatures will warm into the upper 40s to mid-50s across much of the region as we see some sunshine this afternoon. A cold front will move through eastern Oklahoma and western Arkansas later this afternoon and evening right on the heels of the departing mid-level shortwave.
This cold front will set the stage for a chilly start to the new year.
With cold air in place across the region, the mid-week storm system is beginning to look more likely to create some wintry weather across the area Wednesday into Thursday.
The operational GFS and ECMWF are in much better agreement with the handling of the mid-level low that is expected to move out the southwest United States Wednesday and across central and southern Oklahoma on Thursday.
This forecast will show a swath of rain/freezing rain across southeast Oklahoma into northwest Arkansas Wednesday into Thursday before a transition to snow Thursday evening.
Expecting mostly light snow across northeast Oklahoma late Wednesday afternoon into Thursday night. Impactful accumulations of snow and ice will be possible. Even though confidence is growing in
the forecast for a mid-week winter weather event, many uncertainties remain. Stay tuned as the forecast continues to be refined as we approach mid-week.
As we move into Friday and over the weekend, temperatures are expected to
trend upward as high pressure builds at the surface and aloft.
