If you are looking for tomorrow's conditions, the long TAF (issued by about 6 p.m.) will tell you what is likely to happen. For VFR you'll want good vis (preferably 9999 - 10km plus), and a cloudbase at least 1000 feet (preferably 2000 feet) above the highest obstacle en-route. Check how conditions are going to change with time, to ensure you can be back or wherever you are going before it goes to worms - and remember it will always take longer than you think!
You'll also want to check the predicted winds at your origin and destination to ensure any crosswind will be in your personal limits. You'll need the upper winds to plan your enroute time and heading, and again preferably, you don't want gusting winds for either enroute or landing, as a bumpy ride is not enjoyable.
Before you set off, make sure the METARs make sense compared to the TAFs and pay particular attention to temperature and dew point. Remember as it gets later, the temp may drop and if they are already close you risk mist and fog for your return.
At this time of year the sun never rises very high, and if you are landing to Southwest sometimes it's hard to even see the strip if looking into sun! Add poor vis and could ruin your arrival.
The more you do, the easier it will become to set your personal limits.
