Yes, if it feels that dry already then jar it. If its crunchy on the outside but the stems are still wet then what will happen is as soon as they sit in the jar overnight the moisture will even out. Moisture will move from the wet stems back into the dry parts. Once this happens make sure you remember to burp your jars every day to control the moisture. I would assume that in your area excessive moisture/mold is probably more of an issue than overly dry conditions. If you put your nugs in the jars a little early its ok so long as you are really on top of your game watching for mold/condensation.
