Per SpaceX just a few moments ago, GPS is officially scheduled for September 30th.

And per that Launch Hazard, so is NROL-44.

Either the NROL-44 launch is going to slip beyond September 30th, a mistake has been made, or we're going to see two launches in the span of a few hours (unlikely).

NROL-44 is scheduled for early morning September 30 UTC, shortly before midnight on September 29 EDT.

The hazard zone that Emre Kelly just tweeted has NROL-44 scheduled for Oct. 1 UTC.

That looks to me like an error or else there's a change that the NGA hasn't emailed out yet.

Per the latest notice from the NGA, the UTC hazard times for the primary day are 03:45 to 05:57 on September 30.

Belated post: weather in the hours before the launch scheduled for 04:02 September 29 UTC, resulting in the launch delay to 03:58 September 30 UTC:

Lightning strike near the pad.  Looking at the launch window.

The Mobile Service Tower could not be rolled back for the countdown, leading to the weather scrub:

A Phase 2 lightning warning has been issued for the #DeltaIVHeavy Space Launch Complex-37 due to thunderstorms at Cape Canaveral. The launch pad crew will clear the complex as a precaution until the weather alert is lifted. https://www.ulalaunch.com/missions/next-launch/delta-iv-heavy-nrol-44

The lightning warning for the #DeltaIVHeavy launch pad has been rescinded, allowing the ground crew to return to their work sites. There appears to be a window of acceptable weather for Mobile Service Tower roll to occur in preparation for launch tonight. bit.ly/div_nrol44

Go for tower roll! Launch Conductor Scott Barney has instructed the pad crew to retract the Mobile Service Tower at Space Launch Complex-37 for tonight's #DeltaIVHeavy rocket launch of #NROL44. Live countdown updates: http://bit.ly/div_nrol44

The launch of the ULA #DeltaIVHeavy #NROL44 mission has been scrubbed. The local weather resulted in a significant delay to pre-launch preparations including the roll of the Mobile Service Tower (MST).

Edit to add:

https://twitter.com/ulalaunch/status/1311085128085536769

When the MST roll began we discovered a hydraulic leak in the ground system required to move the tower which needs further evaluation. Subsequent weather will prevent the team from moving forward with tonightís attempt. Launch is now scheduled for 11:54 pm EDT on Wed., Sept. 30.

Doesnít sound like repair time will be an issue:

Hydraulic hose failure on the MST. Happens now and again. Part on hand, repair underway.   However, the earlier lighting hold ate up so much of the launch window that we will not be able to continue towards a launch tonight.

Would likely still require an air purge & test.
Being a hydraulics specialist, I find it astonishing that hydraulic hoses would fail on such an important item. The main culprit is typically rot (rusting of the inner steel layers), exacerbated in such a wet environment near the sea. They should be changed out more often. An alternative is applying petrolatum tape over the steel ends & removing them at launch time. It's not like they have a high launch cadence.

Doesnít the Air Force pay something like $400 million to keep the vehicle and pad in a level of readiness?

The USAF needs to get their money back. Frankly itís brutally embarrassing.
Superheavy + Starship the final push to launch commit!

Considering the weather issues with MST rollout on Monday, why wouldn’t they have built in additional time for Tuesday’s rollout? Conditions were pretty similar both days. Starting the countdown earlier and building in more of a buffer for weather contingencies would’ve probably allowed for a launch.

Simple answer: Me :-* pretty colors!

Learned answer: I want to legibly document just how many schedule changes it takes to get these four rockets launched.  In pretty colors!

These seem to be very delicate rockets compared to Russian or Chinese rockets, which I've seen launch through a snow storm.

Surprisingly, I have not yet received an update from the NGA for this launch, only for SpaceX's GPS III SV04.

Eric from Arstechnica seems to agree. One launch per year, their complex is 20 years old, maintenance is key, but they probably consider it end of life anyways and Vulcan is the future:
