I just read this in my local NWS forecast discussion.

“Moving into Sunday, eyes turn towards a potent upper-level trough to
our west. There is a lot of uncertainty at this point as to exactly
what the main impacts from this system will be as it moves in our
direction, as well as exactly when impacts may arrive. But there is
the potential for a potent low pressure system and cold frontal
passage. It will all depend on the track, so will have to monitor
for a potential heavy rain and/or severe weather threat as we get
closer in time and have a bit more consistency.”

I am not sure they actually now how to predict anything without the GFS model.
