Six Weather Numbers Worth Remembering
Most of what our guides explain comes down to a handful of rules of thumb. Each one below links to the guide that explains it, with the official source behind it.
| Rule of thumb | What it tells you | Read more |
|---|---|---|
| Seconds ÷ 5 | Count the seconds between lightning and thunder and divide by five: that is the distance in miles. If you hear thunder at all, you are within striking distance. | Storm warning signs |
| 30 minutes | NWS rule: stay indoors until 30 minutes after the last thunder. | Lightning myths |
| 0.06 inHg per hour | A pressure change of about 0.06 inHg (2 hPa) per hour or more is what official observations call "rising" or "falling rapidly": weather is changing fast. | Barometric pressure · Weather fronts |
| (Temp − dew point) ÷ 4.4 × 1,000 ft | Estimated height of the cloud base, in °F, from your own temperature and dew point. | Types of clouds |
| Dew point 65 °F or higher | Lots of moisture in the air and it starts to feel oppressive (NWS); 55 to 65 °F feels sticky. The dew point says more about comfort than relative humidity. | Dew point explained |
| SAME county code | A weather radio with SAME only sounds for warnings in the counties you program, so it can wake you at night without false alarms. | How to program SAME codes · Best NOAA alert radios |

Track Real Conditions With the Right Tools
Want to apply what you learn? A home weather station lets you measure atmospheric pressure, rainfall, wind speed, and temperature at your exact location. Paired with a NOAA alert radio, you get real-time severe weather warnings the moment they are issued.
