From the UI-View Help page;
KEY POINTS
1. To transmit a WX beacon, you must be running some sort of software on
your PC that either gets information from a weather station or takes
manually input data, and outputs it into a file in the correct format.
UI-View32 does not directly support any sort of weather station. See
Weather Data Format for more information.
WX data file - Usually this will be a text file, made available by some
other software, which contains the WX beacon information. (See "KEY
POINT 1" above.)
However, it can also be a program that will create the wx text file.
UI-View32 decides which it is by looking at the file extension. If the
file extension is EXE, COM, BAT, VBS or JS, then UI-View32 will run the
program, wait for it to finish executing, then look for a similarly
named TXT file that it has created. An example will make this more obvious -
If the wx data file is C:\WX\WXNOW.EXE then UI-View32 will run it and
look for C:\WX\WXNOW.TXT which WXNOW.EXE must create.
NOTE - UI-View32 will wait for a maximum of 15 seconds for the program
to finish executing.
Weather Data Format
Here, between the two lines of '*'s is the format of the file your wx
software needs to create (the lines of '*'s are not part of the file).

g015 - wind gust - 15 mph
t069 - temperature - 69 degrees F
r010 - rain in last hour in hundredths of an inch - 0.1 inches

The first line is the time the file was created in local PC time. Please
note that the day of the month, the hour and the minute must be padded
to two digits with zeros if needed, so this would be wrong - Jun 1 2003 8:7.
The second line is the wx report, in the format used in APRS "complete
weather reports".
Not all the values need to be sent, but you should at least include wind
direction, windspeed, wind gust and temperature. If any of them are not
available, then replace the value with three dots - "..."
If humidity and temperature are included, then a UI-View32 system
receiving the beacon will also calculate and display dew point
temperature. If temperature and wind speed are included, then a UI-View
system receiving it will also calculate and display wind chill temperature.

What stations does UIView support? I was planning to have it put out at
least Peet Bros format.

Again, with Peet Bros format the T2 will work with it as-is.
