Every station ranked. Every forecast scored. Weather for every autonomous machine.
Storm Station 247 reads 82,902 weather instruments across the United States, ranks each one every day and scores its own forecast against what happened. Every reading names the instrument it came from. Drones and driverless trucks read the same engine: the air under 400 ft at any point, and the road every quarter mile of I-45 and I-10, each judged against the operator's own limits.
Now. Columbus is 40° and clear at 7 AM. The dew point is 37°, so the air feels dry and comfortable. Light air from the south-southwest at 3 mph.
Where now comes from. The forecast for this hour, checked against 4 instruments within 24 miles. The nearest, Citizen station GW2783 (247 rank 1,312 in Ohio), read at 7:10 AM.
Today and tonight. It warms until about 3 PM. Tonight falls to about 41° by 7 AM, under a mostly clear sky. No rain is expected for the rest of the day. Air quality is moderate (index 56): fine for most people, though people unusually sensitive to air pollution may feel it outdoors.
The week. The warmest day ahead is tomorrow, near 63°, and the coolest Friday, near 45°. Rain is likely tomorrow (51%) and Thursday (79%). Rain is possible Friday (30%). The first freeze could come Saturday, a low of 30°.
The sky tonight. The sun sets at 5:20 PM. The Moon is a waxing crescent, 3% lit, and sets at 6:01 PM. The next full Moon is Tuesday, Nov 24. After dark, look for Saturn, bright in the east-southeast. A planet shines with a steady light where the stars around it twinkle. The sky is forecast to stay clear: a good night to look up. The day is 10 hours 10 minutes long, 3 minutes shorter than yesterday.
