A/C barely cold while driving on highway

[TexomaExplorer]

1996 Ford Explorer XLT 4 door 2wd V6

I got the a/c filled and its kinda cold.. But when I'm on the highway, it seems its less cold than when I driving say 35 mph through the city.

Any ideas why it would do this?

If you just had it charged, I'm assuming it has a leak... Has that leak gotten bad enough to leak out in that short a time? Do you hear the compressor cycling a lot?

Compressor runs as normal. Doesn't cycle very often. I got it filled towards the end of last season, but never ran the a/c much because it didn't get that hot until just now. I'm normally a "windows down" type of guy, but the better half requests the a/c and its not performing to her standards lol
