You might be able to do that MapServer, depends on how sophisticated the
labeling needs to be. Version 3.7 lets you offset features so you could
define complex presentations around a station point using multiple
layers. As long as data could be stored in shapefiles or another
supported format you'd be ok.
You could also do something like:
http://thoreau.dnr.state.mn.us/weather/map.html
Where detailed station data is presented when the mouse moves over a
station, while displaying more general data in the map itself. In this
case we store station data in XML files but could easily access a
version of the data that is stored in a relational database.
Just thinking out loud...

I believe this to be the case. Specifically, what I'v envisioned is a
mapserver baselayer and core functionality as a mapservice, with
weather
station sites overlaid thereon, as queriable objects. I'd like to find
a way to update the station data as new data rolls in (temperature, dew
point, barometric pressure) as well as setting a wind barb character
and
rotating same to reflect the direction
Specifically, what we're doing is creating the demo site for a
"Mesonet"
or a statewide, dense network of weather stations reporting conditions
in near real time. (Sean, look at www.mesonet.org for a well
established example.)
We're working under some time constraints that are some where between
ambitious and unrealistic to get an initial site up. That's why I
decided to solicit some input here rather than trying to reinvent the
wheel.
Thanks!
