I didn't see my station on MesoWest either.
There is this notice:

Due to some processing upgrades, our data access to stations within the Citizen Weather Observing Program (CWOP) network may be delayed or offline for some time over the next 48 hours. Once the upgrades are complete, data for all active CWOP stations should resume. We thank you for your patience.
Interestingly, my CWOP station CW4114 is not showing on GRLevel3 (with CWOP layer on), but my APRS feed (same data except wind) is OK (KE8DAF-13).
EDIT: I am now seeing it on GRLevel3 all of a sudden...Greg H.
