The latest trends in the models do not support snow for the southeast next week. The last couple of runs of the ECMWF, GFS, and Canadian show the s/w shearing out more and not having enough room to cut off from the flow and form a storm near the southeast coast mid to late next week. There are still a couple members of the GFS Ensemble that show a system bringing some snow to eastern NC, but overall there are less models and ensemble members showing this solution this morning than 24 hours ago.
The synoptic scenario remains the same, a sharp trough will set up over the eastern US early to mid next week with the coldest air of the season moving into the eastern US. A 2nd trough in an energetic pattern will move into the Pacific NW early next week and then either shear out and move across the northern US with little impact here except a frontal passage. The 2nd scenario is that this trough separates more from the mean flow and has room to dig into the lower Mississippi River Valley and help form a low pressure center near the southeast coast. If this happens with the cold air around we could see some light snow in parts of the southeast. The scenario is still on the table, but most evidence is against it right now.
The next 3 days look mild with highs in the Triangle in the low 60s today and tomorrow and into the mid to perhaps upper 60s on Sunday. However, a strong cold front moves through Sunday night with temperatures much colder on Monday likely not getting out of the 40s. It will not get out of the 30s on Tuesday with lows Tuesday morning near 20 and perhaps in the upper teens Wednesday morning, before we watch to see if any mischief is stirred up by the aforementioned scenario.
Beyond this, it looks like the pattern will go to a –PNA pattern which will mean a trough in the western US and likely a renewed mild pattern for the 2nd week of January.
