FAQ: Your Weather Questions Answered
1. What does “11% chance of rain” actually mean?
It means if you had 100 days just like today, it would rain on only 11 of them. In other words: probably dry, but not a guarantee.
2. Should I cancel my Tuesday evening picnic?
With a 73% chance of thunderstorms, it’s risky. Have a backup plan (indoor space or tent) or reschedule for Thursday/Friday.
3. Why does the wind direction change every day?
Wind follows pressure systems (big swirling air masses). As they move, the wind shifts—like a revolving door of air!
4. Is 5–10 mph wind strong?
Nope. That’s a gentle breeze—you’ll feel it on your skin, see leaves rustle, but it won’t blow things over.
5. Why is Sunday night’s temperature the same as the morning (78°F)?
That’s likely a data mistake. Nights in August usually cool to the 60s. Expect ~62°F, not 78°F.
