Term Simple Meaning
Mostly Sunny The sun is out most of the time. A few clouds might visit.
Partly Cloudy Half sun, half clouds. Like a peek-a-boo sky.
Showers Light rain that starts and stops. Not a downpour.
Thunderstorms Rain + lightning + thunder. Stay inside if you hear thunder!
Precipitation Chance The % odds that any rain/snow falls. 10% = “probably not.” 70% = “likely.”
Wind Direction Where the wind is coming from. “North wind” = blows from north to south.
mph Miles per hour. 5 mph = slow walking speed.

  • Temperatures stay comfortable – highs in the upper 70s to low 80s, lows in the upper 50s to mid 60s.
  • Winds stay light all week – never above 10 mph. No kite-flying wind, but no dangerous gusts either.
  • Sunday’s night temperature (78°F) matches the daytime high – this is unusual and may be a data error. Expect cooler nights (likely ~60°F).

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.
