As you are a new PPL I would add a word of caution on relying on reported weather!
Remember many airfields do not report weather as such and its important to check by phone for visual observations.
Checking for weather at a station 20 miles away and others may give you a picture but doesn't account for localised weather as in the recent Malibu crash.
Actuals can change enroute and TAFS can be out as I have found on many occasions.
Really you are building a picture and in the early days its better to keep your margins large until you have the skills to handle most weather that is thrown at you.
As in all things aviation trust nothing including weather and always have can exit plan
