I’ve been using this weather forecast website more and more since it has less HTML/cookies/marketing/attention-stealing garbage all over it, seems to be generally accurate as opposed to fake accurate (“your up-to-date right at you longitude & latitude weather per minute!!”), and if you click into the larger/main area for today you can see the previous 5 days of forecast for today, yielding some idea of the forecast stability.
I don’t bother with forecasts anymore. I just go prepared. I have insulated coveralls in case it gets real cold. Long sleeve FR shirt and a full brim hat for when it’s hot. Yes I wear long sleeve shirts when it’s 100 degrees out. Trying to keep my arms from hopefully getting skin cancer.
Mainly I use forecast for rain…generally a fool’s errand, I realize. But if I have reasonable confidence it is going to rain that day or next, I tend to adjust watering of my landscape and etc.
