The effects of the upper low in central Louisiana continue to be felt across parts of Eastern Oklahoma and Western Arkansas, but will come to an end tomorrow. Showers remain across areas to the southeast of I-44 in the wraparound region of the storm system, the northern edge of which is very slowly creeping eastward in radar trends, despite the southwestward movement of the individual showers. The area of rain and low clouds associated with the low will push eastward overnight and into tomorrow morning as the system begins to pick up steam, pushing to the northeast.
Warmer temperatures will arrive tomorrow and persist into Sunday as skies clear and upper level ridging builds into the area. A weak front will move through late Sunday that will knock temperatures down a few degrees for Sunday night and into Monday, but warmer conditions will arrive again for Tuesday ahead of a stronger mid week storm system.
Both the GFS and ECMWF are on board with the mid week storm system, although there are some timing and strength differences, both between their latest runs and their previous counterparts. Will bump up POPs a bit on Wednesday from the inherited forecast into the low chance category, with potential for additional increase on future forecasts once some of these inconsistencies are resolved. Overall, even in the wake of this system, temperatures next week appear quite pleasant by mid to late December standards.
