Along the lines of METAR/TAF watching, plan a "flight" somewhere every morning, far enough to provide some weather and routing challenges. Look at prog charts and fronts, forecasts, etc., make a "go/no-go decision, then as the day progresses, watch how actual METARS progress. Basically, do a self-briefing, all with the idea of getting a feel for weather interpretation.
And, I understand not wanting to overload memory banks by starting instrument ground training, and I surely hope you can get your checkride done on schedule, but if it gets further deferred, delving in to your IFR materials might be a good option.
