Show me a temperature plot in fahrenheit for tonight in narragansett rhode island using the earthmover/aifs repo on arraylake
🤖 Claude
I explored the earthmover/aifs repo on Arraylake — it's the ECMWF AIFS Single forecast dataset (AI-based weather model, 0.25° global, 6-hourly forecasts out to 15 days). Latest initialization available: 2026-04-23 12:00 UTC.
Queried the EDR service at the grid point nearest Narragansett, RI (41.5°N, 71.5°W) for the temperature_2m variable, then converted from Celsius to Fahrenheit.
Forecast for tonight (EDT)
| Valid time (EDT) | Lead time | Temp (°C) | Temp (°F) |
|---|---|---|---|
| 2pm today (18Z) | +6h | 17.1 | 62.8 |
| 8pm tonight (00Z) | +12h | 13.1 | 55.5 |
| 2am overnight (06Z) | +18h | 7.6 | 45.7 |
| 8am tomorrow (12Z) | +24h | 7.9 | 46.2 |
A typical spring overnight — cooling about 10°F from evening into the pre-dawn hours, bottoming out in the mid-40s before sunrise.
