Autumn arrives tomorrow, but it always comes a little later to the southeast than the rest of the country. How summery will the end of September be?
At 853PM, ET, Greenville was reporting a temperature of 70 degrees with overcast skies. In the ever unraveling saga of Nicholas, he is finally being dragged north towards the Eastern Great Lakes, but a plume of remnant moisture extends from western Pennsylvania to central North Carolina. Of more interest is a sharply digging upper level trough that is reaching into the Lower Mississippi Valley this evening. While the remnants of Nicholas are east of the Appalachians, cyclogenesis will be very autumnal thanks to the trough over the next couple of days.
AS the trough rotates a bit and moves east, the latent moisture left by Nicholas will be expressed as widespread showers with some isolated embedded storms. The low generated by the trough is fully evolved, even dropping a cold front that will press through Greenville tomorrow evening. The air behind the front will be dry and refreshing after so many days with rain in the forecast.
