Here, we can get a light frost as high as 39° F, depending on dew point, cloud cover and wind.

The National Weather Service forecast is for a low of 23 tonight with

Mostly I'm just complaining about the weather but my question is, how
can the NWS call 23 degrees "Patchy Frost"? Wouldn't that be a pretty
widespread frost at that temperature? Wouldn't it actually be a hard freeze?

Around here we often get the reverse problem in the forecast: "Widespread frost predicted tonight with lows in the mid-thirties." Huh?

To partially defend the weather service: this is an area where it's perfectly possible for a significant chunk of their covered area to have frost or even hard freeze, while other portions of the area have temperatures in the midthirties or even in the low forties. But I still think the above forecast would make much more sense phrased as, "Lows in the mid-thirties in some areas, but significant areas of frost expected". (The actual result, right where my thermometer was hanging, turned out to be 33º; I'm in neither the coldest nor warmest place that they cover. I have a friend in a cold spot who may well have gotten mid-twenties last night.)
