Why weather_code Alone Won’t Cut It: Building a Severity Scale from Raw API Fields
Condition codes tell you what’s happening, not how bad it is. Here’s how to build a real severity layer from WeatherAPI’s raw fields.

How to Build a Real-Time Frost Prediction Alert Using Dewpoint, Temperature, and Sky Cover Together
Condition codes won’t catch a frost before it forms. Here’s how to combine dewpoint, temp, and cloud cover fields to build an early frost alert that actually works.

How to Build a Dew Point Crossover Alert: Detecting the Exact Hour Conditions Flip from Comfortable to Oppressive
Dew point tells you more about outdoor discomfort than humidity does. Here’s how to detect the exact forecast hour it crosses into oppressive territory.

Reverse Geocoding Weather Requests: Why lat/lon Precision Matters More Than You’d Expect
Coordinate precision in weather API requests isn’t just a formatting choice — it directly affects which station gets selected and the data you get back.

What Weather API Responses Don’t Tell You About Data Provenance (And How to Reconstruct It)
When a weather API returns a number, do you know where it came from? METAR, NWP model, or blended? Here’s how to figure that out and why it matters.

Chasing the Right Model Run: Why Your Forecast Data Is Older Than You Think
GFS, NAM, and HRRR don’t publish instantly after their run cutoff. Here’s how model run latency affects what your weather API actually returns.
