Monsoon season and LAS actually had thunderstorms and a little rain this afternoon.... the airport is a mess. They did have an earlier ground stop, followed by a several hour ground delay program that has recently been dropped.

ATCSCC ADVZY 083 LAS/ZLA 07/18/2021 CDM GROUND DELAY PROGRAM

Assuming they don't change it, N244WN is your plane....it came from BUR and has been on the ground in LAS since 5:20pm local. It's operating #2720 LAS-OAK and is currently in-line for departure.

Best of luck to you.
