NOAA/NCEI Climate at a Glance, contiguous United States. This is the observed record for the month, not a score of anything said in this piece — the forecast ledger begins 2026-08-17 and cannot reach earlier posts.

An even better day as more sunshine warms the Lower 48 from California to North Carolina. Only a few areas of active weather. Can you feel the Spring Fever?

Huge day as Europe’s weather agency launches their Artificial Intelligence Forecasting System (AIFS) into operational use. It is available 4x per day or every 6-hours, and around 12:45 PM ET for the 12z cycle.
