En-Route
I am guessing at where you are, where you are going and how fast you can go!
The one nagging problem with his route of flight is the throat in SC. To the East, there are RA/-TSRA over the Atlantic that have a 30% probability of going convective in the next 120 min. There is +RA at FL270 over W/W-C SC, and +RA/TSRA with convective building over Savannah. With onboard, uplinked, and sferics you still have a tight, and closing, throat to weave to make it up to NC.
