Hi,
Do you know about these cloud forecasts? Neither is perfect but they do help. I like to compare the forecast to reality for hours or a day before my obs night to see how accurate they are at that time. The accuracy depends a bit on the type of weather system. Where I am it tends to get it wrong when there is an on-shore wind because they don't model the effect of the escarpment well. They may do better at your place, being pretty flat there.

Don't let bad weather put you off. I've been into astronomy for 40 years and I've stood under cloud, fuming, quite a few times. Even had the scope rained on. But I've also had some of the greatest nights ever and seen thing most people don't even know exist. Apart from hundreds of DSOs I've seen 3 total solar eclipses, two transits of Venus, transit of Mercury, planetary occultations and a few lunar eclipses. If you persist you too will have a collection of very happy memories by the time you're my age. BTW I suppose you are already planning for the 2028 solar eclipse? (I am)
