Please note that, because of the simultaneous visual sightings (I don't know if there were any direct correlations), I'm not saying that there was nothing unusual going on.
The operator also showed me what his height-finding radar was manifesting that night --- I've drawn colored bars on one of his blanks to show that above. These things gave back "spikes" which stood as if suspended in the air, but which terminated quite high [unlike anything which anomalous propagation would do.] There was a sudden leap in height from 25,000' to nearly 50,000' which occurred at the most in 17 seconds. So the return gained that altitude at roughly 1100mph. Some of the lateral jump speeds seemed greater.

The news article you linked interestedly says the 911 calls witnessed tree top level sightings, yet the weather operator reported echoes from 10000 feet and above. Thats a pretty big discrepancy, what could make such a distance in 94>?
This section goes on about how the radar replication reports were acquired and additional information reported that was not made public during the flap of March 8, 1994. Some of the additional highlights are:
• Several minutes before the 'objects' appeared on the exhibit radar printout, other objects were tracked by sophisticated sites across the United States.
• The first group of 24 objects approached the west coast of California from the southwest over the Pacific Ocean and appeared to be on a course toward Lake Michigan.
• At about the same time, a group of 14 objects were tracked approaching the south east from Florida and an additional group of 24 objects approached from over the Alaska and the Northwest Territory of Canada, also appearing to be headed toward Lake Michigan
• Simultaneously, a group of 12 objects appeared approaching from the East Coast of the United States coming from the north east and were observed at Loring AFB.
• All the groups actually converged at a point approximately 52,000 feet above the north central portion of Lake Michigan.

In fact, didn't they (the military) just come out with a disclosure last week stating that most of the older (and probably current?) UFO reports were due to their secret flight-related tests?
Around 17 minutes in the recording, the weather center radar operator talks about "instantaneous movement". Anomalous propagation can exhibit such characteristics, while physical objects generally can not. So I interpret this as strong support for an explanation of some natural phenomenon and not any kind of solid object.

Anomalous propagation can produce all kinds of strange effects.
If the refraction is strong enough, it's even possible to pick up distorted lights from ground sources, but there was also some comment about antenna lights nearby that were flashing in a pattern similar to what was being observed.
Air Force Captain Harold May was in the radar center at Andrews AFB during the sightings of July 19–20. Upon hearing that National Airport's radar had picked up an unknown object heading in his direction, May stepped outside and saw "a light that was changing from red to orange to green to red again...at times it dipped suddenly and appeared to lose altitude." However, May eventually concluded that he was simply seeing a star that was distorted by the atmosphere, and that its "movement" was an illusion.
Is anomalous propagation visual from the ground to the naked eye ?

Yes, the answer is yes.
As far as the radar-spoofing is concerned? We know for sure that we have the technology to spoof radar. We have anecdotal stories from WWII pilots that were flying along with other aircraft that were using the radar-spoofing equipment of luminous balls of light that they could see that they called "Foo Fighters".
What we don't know is if radar-spoofing equipment that produces artifacts that can be seen by radar and the naked eye has been developed.
You can read aboout it in member mirageman's recent thread.

I sure think it was some unknown weather thing though.
This happened in March. We know from the tape that the aurora borealis was very active that night.
Stratovolcano Galeras had just erupted in January, sending up a 12km plume, maybe the dust ended up over the Great Lakes region in March. And then there's big 'ol reflective Lake Michigan.
One can only speculate, I suppose.
So it's solved
You answered yes, but in what form is it visual to the naked eye?
When there are atmospheric distortions in the refractive index of air in different places, both visual and radar effects can be observed, as happened in the 1952 Washington DC UFO case, so a visual correlation still doesn't rule out variations in the refractive index of the atmosphere:
Both are caused by variations in the refractive index of the atmosphere.

The Washington DC event was explained by atmospheric distortions and not anomalous propagation, which I believe are two separate occurrences.
That description sounds a lot like this case to me except for some quibble about the altitude which may just be our ignorance of the scope of this phenomenon in more unusual circumstances.
AP is a false reflectivity echo on radar (a reflectivity echo that is NOT precipitation, especially echoes produced by unusual rates of refraction in the atmosphere). In cases where the index of refraction is unusual, AP is much more likely to show on radar. In extreme cases, the air near the ground may be so cold and dense that a radar beam that starts out moving upward is bent all the way down to the ground. This produces strong echoes at large distances from the radar. Generally, the Doppler velocity of AP echoes is zero, but the echoes themselves can move around because propagation characteristics of the atmosphere keep changing.
Here is the evidence that was happening in the Washington DC 1952 UFO case:
b. HIGH SUPERREFRACTION- Superrefraction is also termed ducting if the radar beam bend down toward the earth's surface enough to actually intersect the earth's surface. When radar beams bounce off the earth's surface some of that energy will backscatter to the radar to show AP.
Among the witnesses who supported Samford's explanation was the crew of a B-25 bomber, which had been flying over Washington during the sightings of July 26–27. The bomber was vectored several times by National Airport over unknown targets on the airport's radarscopes, yet the crew could see nothing unusual. Finally, as a crew member related, "the radar had a target which turned out to be the Wilson Lines steamboat trip to Mount Vernon...the radar was sure as hell picking up the steamboat."
The troposphere is the seat of powerful processes which originate separation of electric charges. Thunder clouds give rise to a huge vertical separation of charges. But also known is a different electrification mechanism activated by wind, which allows for horizontal separation of charges.
In favourable conditions, when charges are displaced at long distances, image charges appear in the ionspheric plasma and an upward electric field is originated which makes the ionosphere boundary unstable. If this occurs, recombination of displaced charges involves ionosphere conductivity and gives rise to a downward electron stream ejected from the bottom of the ionosphere.
It may produce a peculiar airglow phenomenon, which consists of the emission of light in a narrow region lying at stratospheric or mesospheric altitudes. This outcome of the electrification process just mentioned shows a close connection with a special class of «UFO» sightings, that is, those referred to by J. Hynek as «nocturnal light» and which consist of bright specks of light moving in the night sky.
