I would imagine NWS Norman had enough on their plate that day without adding grammar specifics to the list.

Why would 24-hour time be mentioned? This is a statement for the public, who probably know 7:17 PM far more than 19:17.

Like this: Take UTC time (5:30PM right now) and convert it to Military time. Result is (1730z right now)

24h Zulu times are used for internal consistency between NWS offices, but public-facing offerings need to be in 12h local time. If you're under a tornado warning, you have about ten minutes to decide whether or not you're going to take cover. It's important to eliminate any possible error that could result in someone failing to take shelter, like someone thinking a message is outdated because they botched UTC-to-local or 24h-to-12h conversions.

A recent Snow Squall Warning from my neck of the woods via the mesonet:

BULLETIN - IMMEDIATE BROADCAST REQUESTED
Snow Squall Warning
National Weather Service Missoula MT
815 PM MST Sun Feb 16 2020

MTC039-063-170415-
/O.NEW.KMSO.SQ.W.0004.200217T0315Z-200217T0415Z/
Missoula MT-Granite MT-
815 PM MST Sun Feb 16 2020

The National Weather Service in Missoula has issued a

* Snow Squall Warning for...
  Southeastern Missoula County in west central Montana...
  North central Granite County in west central Montana...

* Until 915 PM MST.

* At 815 PM MST, a dangerous area of intense snow was located 7 miles
  southeast of Bonner-West Riverside, or 10 miles southeast of
  Missoula, moving southeast at 5 mph.

  HAZARD...Poor visibility in heavy snow.

  SOURCE...Radar indicated.

  IMPACT...Dangerous life-threatening travel.

* Interstate 90 Missoula to Bearmouth, and Highway 200 Bonner to
  Potomac.

Locations impacted include...
Missoula, Bonner-West Riverside, East Missoula, Nimrod, Bearmouth,
Clinton and Turah.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Consider avoiding or delaying travel until the snow squall passes
your location. If you must travel, use extra caution and allow extra
time. Rapid changes in visibility and slick road conditions may lead
to accidents.

Very rare occurrence of a Snow Squall Warning. This confuses me because a snow squall constitutes a winter storm, right? But why have two warning products for the same effect? You got snow, you got wind, wind chills, drifting, and icy conditions. Should the NWS offices merge Snow Squall Warnings into Winter Storm Warnings?

When I JUST got into Longhorn's parking lot, this suddenly blasted out of the blue! :wow:
Notice it was raining hard on my dashcam app on my cell phone.

They aren't the same thing. Snow squall warnings are issued when visibility is expected to drop to <1/4 mile in heavy snow with temperatures below 32F (implying that the snow will stick to the ground), causing dangerous and life-threatening conditions for a time period of less than 60 minutes. Think of it like a severe thunderstorm warning but with snow.

Winter storm warnings, on the other hand, are usually issued when a storm is expected to drop heavy snow over a longer time period (generally a day or so). The snow amount criteria for a winter storm warning varies depending on where you are in the US - just half an inch is enough in the Florida peninsula, but you need a whole foot for a warning in many of the higher/snowier mountains out west.
