Synopsis
The upcoming weather for the weekend will be rather dry, but also sunny as a blocking high will dominate our weather pattern for the weekend. a prospective nor'easter that has been in the news will not be influential much along the northeastern coast, but it is something to keep an eye on for the week.
Short Term (Now throughout Friday night)
Currently, the state is along a surface high pressure ridge that is extending all the way into Missouri. This ridge will dissipate a little it gets sandwiched by a cold front up in northern Ontario. A shortwave trough will make its way into the state on Friday afternoon (around 18 to 21z) however this will leave little influence on our weather directly, and as day turns to night, this shortwave will undergo a sharp turnibf as a 500mb ridge, oriented NE to Sw, will deform this shortwave and will begin to cut it off from the mean flow.
Long Term (Saturday through Monday)
Saturday morning, the shortwave will turn a strip of positive vorticity toward the southern parts of the state(in a windshield wiper-like fashion). With this, positive vorticity will get sucked into the cutoff low hat will be hanging out to our south over Eastern TN, northern GA, and western Carolinas. This low will enhance a coastal system that will precipitate over the Carolinas and eastern Georgia. this is in part due to the wide 500mb trough moving toward us in addition to the surface high shifting to the Northeastern U.S. on Sunday, he high to our northeast will begin creating a cold air damming scenario that will keep temperatures below average locally and across the East coast. This will remain in effect for Monday as well, and the high to our northeast will serve as a blocking high that will push he southern cutoff system out to sea and not the recovering east coast.
