A front is sweeping across the Carolinas tonight, and this will help to usher in a cooler air mass.
Clouds and that slight chance of a shower will remain for Wednesday with the front still in the area. With limited sunshine expect temperatures to climb into the low 70s west of I-85, and only into the mid to upper 70s east of I-77 tomorrow in North Carolina.
This taste of fall will remain through the weekend with temperatures 5-10 degrees below average for mid-September. Skies will remain partly sunny until the weekend, when drier air aloft moves into the area. Rain chances will remain confined to the coastal areas on Thursday where the front is stalled.
Temperatures over the weekend will rise to slightly below average for this time of year, but there does not appear to be any major weather systems racing towards the Carolinas through the middle of next week.
On Sunday or Monday, I am watching another powerful cold front that has the potential to bring some of the coolest and driest air that we have seen this fall season. The jury remains out on how cool it will be, but some areas in the mountains and foothills could dip into the 40s or low 50s next week.
