Data is released every minute, every five minutes, every hour, and then 6 hour high/low, and then mid-day preliminary reports, so there is no last-minute since any one of those reports could contain data (with various validation/rounding caveats) that could eliminate a market of temperatures, so there isn't really a last minute.
My conclusion was to focus on forecast and attempt to predict the temperature better than forecast vs. market implied probability rather than attempt to respond very quickly to published information. I learned (with my skills) the latter was a losing proposition, but the former isn't impossible (although also possibly beyond my skills it seems).
