There's a chance that the temperature tonight <i>could</i> <i>potentially</i> hover somewhere <i>around</i> 34ºF. There may be a 50% chance that the temperature <i>could</i> fall between 33 and 35ºF. The range of potential lows <i>could</i>, in theory, span from 31 to 37ºF, but these extremes seem far less likely. There also seems to be some indication that it <i>could</i> be more likely to be cooler than warmer within that range.
