Alert. A Severe Thunderstorm Watch is in force for Chillum until 8 PM today. Read the alert in full, and see what it means in the Field Book. Rain is likely this evening, from about 7 PM, the chance peaking at 67% around 8 PM.
Now. Chillum is 65° and mostly cloudy at 2 PM. The dew point is 68°, so the air feels oppressive. Light breeze from the south-southwest at 7 mph.
Today and tonight. It warms to about 83° by 4 PM. Tonight falls to about 50° by 7 AM, under cloud. Air quality is moderate (index 53): fine for most people, though people unusually sensitive to air pollution may feel it outdoors.
The week. The warmest day ahead is Tuesday, near 64°, and the coolest tomorrow, near 55°. Rain is possible tomorrow (49%) and Monday (31%).
The sky tonight. The sun sets at 6:28 PM. The Moon is a waxing crescent, 33% lit, and sets at 10:25 PM. The next full Moon is Monday, Oct 26. After dark, look for Saturn, bright in the east-southeast. A planet shines with a steady light where the stars around it twinkle. The Orionids meteor shower is active, peaking around Oct 21: at its peak, up to about 20 meteors an hour can be seen from a dark site. Cloud is forecast to cover most of the night, so the sky will be hard to see. The day is 11 hours 11 minutes long, 2 minutes shorter than yesterday.
