Warmest and coldest use the average of NWS, American, European. "Rain most certain" ranks by the lowest chance among the models that give one (at least two), so a place only makes the list when they agree, and only from 30%. One place per area, so the list spreads across the state.

Estimates from NASA POWER (GEOS-IT weather analysis, FLASHFlux satellite sunlight), not forecasts or station readings. Warmest and coolest are the average daily high. "Sunniest" is the sunlight that reached the ground as a share of what a clear sky would give at that latitude and date (FAO-56 clear-sky formula, approximate). Each value covers an area of about 50 km around the town, so one town per area. Rain is left out because weekly rain estimates differ too much between data sources to rank them honestly. The week ends a few days back because the sunlight data arrives with a delay.

Which forecast is most accurate in Louisiana?

Over the last 30 days we graded the models in 18 Louisiana cities against the recorded weather. The European model was most accurate in 18 of them. No model wins everywhere, which is why each city page names its own winner.
