Default FAA "Centers" have primary radar?

In another thread I am in a discussion on radar capability for FAA
"Centers". My recollection is that they typically have no primary radar,
thus no capability to paint weather.

There is no connection whatever between 'primary radar' and 'weather radar'.

The ability to detect storm clouds is related purely to the wavelength of the
radar transmission. A radar that was swamped by cloud returns would be utterly
useless as a primary radar !

Bzzzt, wrong answer.

The ablility of radar to detect weather is related to frequency, antenna
polarization, antenna sweep rate, type (as in pure pulse versus doppler)
and signal processing (if any).

Mainly frequency actually. If not ENTIRELY frequency. The effect was found by
accident during WW2 btw.
