There are solutions for getting the data out of the bridge to use locally, but I wrote my own a year or so ago (as several others have). I avoided posting my code just because I didn't want Acurite trying to circumvent it by using SSL or some other method to defeat it, and wanted to wait and see if they upgraded it because of the forthcoming Atlas. However now that they want to dump the bridge, https://github.com/billfor/acurite-bridge
If using it, make sure to set $FAKEVERSION=224 and $PARANOID=TRUE. That way no matter what acurite sends back to the bridge, it will always behave the way it has, and you will always have local data.
