Hard to get much that isn't an inaccurate semi-toy for $150 total including 
computer, but you could probably do an AcuRite 5-in-1 from Costco plus a 
raspi + SD + power supply for that, although the AcuRite stations sound 
like they might be a bit unstable.

I'm sure others will chime in with alternatives....

Weatherproofing and powering everything will likely be your main issue I'd 
guess.  You're gonna need to power the multiple sensors.

Here's a totally random link just to give you some examples of cheap 
alternatives if you're willing to build stuff yourself - 
https://github.com/squix78/esp8266-weather-station - you could do something 
similar with a pi zeroW and DS18B20 sensors for just a few bucks, but once 
again powering the zeroW(s) is likely the biggest issue.
